1 INCINERATOR CHARGING / LOADING THE WASTE FEEDER Load the incinerator in such a manner as to limit the operational capacity of the system to 681 kgs (1500 lbs.) per hour average medical waste. The hopper should be loaded with an average of 136 kgs. of waste per 12 minute cycle. The auto charge sequence is set in motion by closing the hopper lid. The waste feeder will charge the incinerator when the charge cycle timer times out at zero minutes and zero seconds, and the temperature interlocks are satisfied. NOTE: A “full weight” charge may not fill the hopper of the waste feeder. Mix different types of waste when possible. Avoid placing glass into the incinerator if possible. If this is unavoidable, save waste which is known to contain glass waste for the end of the operational day. This procedure will help prevent molten glass from adhering to the refractory liner of the incinerator due to a buffer of ash between the glass and the refractory liner. The auto charge sequence is set in motion by closing of all the waste feed interlocks. These interlocks include the load timer, hopper lid closed indication, and minimum secondary temperature of 1600°F-1800°F, access doors proven closed, heat exchanger temperature interlocks, scrubber pH and water level interlocks, and APC system temperature. CAUTION Keep hands and other body parts clear of ash rams, ash conveyor, and waste feeder when the hydraulic system is in operation. CAUTION Lock out HYDRAULIC PUMP ENABLE SWITCH and remove key before servicing waste feeder hopper door(lid), ash conveyor, ash rams, fire door, or charging ram. INCINERATOR OPERATION BEFORE start up manually run the ash conveyor forward for one minute to clear any buildup of ashes from the tank bottom and to confirm ash conveyor operation. PANEL CONTROLS INCINERATOR START KEY SWITCH Rotating of the SYSTEM START key engages the control system and initiates the purge cycle. Before the system will start the following interlocks must be satisfied:

1) The primary and secondary chamber access door must be proven closed. 2) The automatic waste feeder fire door must be proven closed. 3) The automatic waste feeder hopper lid must be proven open. 4) The SYSTEM START key operated switch is rotated momentarily. The start up sequence is as follows after the pressing SYSTEM START: 1) The combustion air blower(s) starts. 2) The incinerator completes the PURGE cycle and begins to PREHEAT. 3) The ID fan and heat exchanger cooling fan will start. 4) The scrubber tank will add water as required. 5) The bypass stack cap will automatically close with limits proven. The position of the stack cap is proven both “closed” and “not open” for various process interlocks. 2 INCINERATOR MANUAL STOP PUSH BUTTON Pressing of the SYSTEM STOP button will manually disengage the incinerator control system. The feeder will not be disengaged if in mid-cycle. This button is normally not used. Note that the incinerator is always, during normal operation in itʼs shutdown sequence. However this shutdown sequence is reset with each waste feed cycle. PRIMARY BURNER No. 1 RESET PUSH BUTTON PRIMARY BURNER No. 2 RESET PUSH BUTTON SECONDARY BURNER No. 3 RESET PUSH BUTTON SECONDARY BURNER No. 4 RESET PUSH BUTTON Allows corresponding burner programmer to be reset in the event of a burner flame failure. PRIMARY BURNER No. 1 ON/OFF/AUTO SWITCH PRIMARY BURNER No. 2 ON/OFF/AUTO SWITCH SECONDARY BURNER No. 3 ON/OFF/AUTO SWITCH SECONDARY BURNER No. 4 ON/OFF/AUTO SWITCH This switch is usually in the AUTO position; in the OFF position the burner will not run; in the ON position the burner will run continuously limited only by temperature and fuel and combustion air proving interlocks. HYDRAULIC SYSTEM AUTO/MANUAL SWITCH In the MANUAL position, the charge ram, fire door, hopper lid, and ash ram switches are operational, and the waste feeder will not cycle automatically. In the AUTO position, the waste feeder will cycle automatically (with the appropriate interlocks proven); And the charge ram, fire door, and ash ram switches are disengaged. The ash conveyor and hopper lid control switches will operate in the auto or manual position.

The ash conveyor, however, will not operate during the waste feed cycle. ASH CONVEYOR OFF / ENABLE SWITCH This switch will enable to the ash conveyor to operate in the Auto, Forward, or Reverse mode when in the ENABLE position. In the OFF position the ash conveyor will not operate. The belt conveyor runs in the forward direction anytime the ash conveyor is operating. ASH CONVEYOR FORWARD/ AUTO/ REVERSE SWITCH IN THE AUTO position the ash conveyor will cycle forward only, for a timed period as set by panel mounted timer TD-8 located inside the control panel. The auto ash conveyor cycle occurs after the waste feed sequence is complete and the hopper lid has opened. In the FORWARD position the ash conveyor will move forward, if enabled, and no other limits stop the movement. In the REVERSE position the ash conveyor will move backward, if enabled, and no other limits stop the movement. The ash conveyor will not operate during the waste feed cycle. The belt conveyor runs in the forward direction anytime the ash conveyor is operating. UPPER ASH RAM EXTEND/RETRACT SWITCH LOWER ASH RAM EXTEND/RETRACT SWITCH This switch provides manual operation of the ash rams by the operator. The HYDRAULIC SYSTEM AUTO/MANUAL SWITCH must be in the manual position to operate this switch. 3 CHARGE RAM EXTEND/RETRACT SWITCH This switch provides manual operation of charge ram by the operator (ram will not extend unless fire door is fully open as indicated by the pilot lamp on the graphic display). The HYDRAULIC SYSTEM AUTO/MANUAL SWITCH must be in the manual position to operate this switch. FIRE DOOR OPEN/CLOSE SWITCH This switch provides manual operation of fire door by the operator (fire door will not close unless charge ram is retracted to "clear" or “retract” position as AUTO/MANUAL SWITCH must be in the manual position to operate this switch. NOTE: Fire door and ram switches are intended to be used for servicing and for occasional use by operators as needed, they are not intended to be used to “force feed” the incinerator. HOPPER LID OPEN/CLOSE BUTTONS (or remote control device buttons) These push buttons provide manual operation of the hopper lid by the operator.

HYDRAULIC SYSTEM EMERGENCY SHUTDOWN PUSH/PULL BUTTON Push in for hydraulic pump shutdown, pull out for normal operation. HYDRAULIC PUMP OFF/ENABLE SWITCH LOCK This switch prevents the waste feeder, and all hydraulic functions from being operated during off-use hours by switching to OFF and removing the key. STACK CAP PUSH TO OPEN MUSHROOM

This mushroom button is normally pulled out for normal operation. The button is pushed in to open the emergency bypass stack cap, to bypass the heat exchanger, baghouse, wet scrubber, ID fan, and scrubber exhaust stack.

MAIN - LOW PRESSURE COMBUSTION AIR BLOWER ON/OFF/AUTO SWITCH This switch is usually in the AUTO position; in the OFF position the blower will not run; in the ON position the blower will run continuously regardless of system status or control interlocks. This blower supplies combustion air to the primary and secondary combustion air injection manifolds. BURNER - HIGH PRESSURE COMBUSTION AIR BLOWER ON/OFF/AUTO SWITCH This switch is usually in the AUTO position; in the OFF position the blower will not run; in the ON position the blower will run continuously regardless of system status or control interlocks. This blower supplies combustion air and atomizing air to the diesel /Diesel burners and gaseous fuel pilot burners. INDUCED DRAFT FAN ON/OFF/AUTO This switch is usually in the AUTO position; in the OFF position the blower will not run; in the ON position the blower will run continuously regardless of system status or control interlocks so long as the baghouse temperature is not over limit. This blower pulls gases thru the stack system, thru the heat exchanger, thru the bag house, thru the wet scrubber, and forces the cleaned waste gases up the final exhaust stack. Due to the high starting load this blower motor is operated by a variable frequency drive which will ramp up the acceleration over a 30 second period from 5 hz to the maximum frequency as determined by field set up. Actual flow thru this blower is limited by a butterfly valve in the blower outlet modulated according to primary chamber negative pressure (vacuum) 4 COOLING FAN ON/OFF/AUTO This switch is usually in the AUTO position; in the OFF position the blower will not run; in the ON position the blower will run continuously regardless of system status or control interlocks. This blower provides a constant but modulated

flow of ambient air to the heat exchanger which is cooling the incinerator gases prior to entry to the bag house. Due to the high starting load this blower motor is

operated by a variable frequency drive(VFD) which will ramp up the acceleration over a 30

second period from 5 hz to the operating frequency as determined by the temperature of the bag house inlet. The bag house temeprature controller outputs a 4-20mA signal to the VFD to maintain a constant 150°-180°C bag house temperature.

LIQUOR PUMP No. 1 ON/OFF/AUTO LIQUOR PUMP No. 2 ON/OFF/AUTO In the AUTO position the liquor pump will operate when the incinerator is in operation, so long as the low water level safety switch in the scrubber is satisfied. In the ON position the liquor pump will operate continuously so long as the water level switch in the scrubber is satisfied. In the off position the liquor pump will not operate. CAUSTIC PUMP ON/OFF/AUTO In the AUTO position the caustic pump will operate when the scrubber liquor pH controller is indicating a pH value of 6 or lower. The pump will operate until the pH value is above 7. In the ON position the caustic pump will operate continuously. This on position is for testing purposes only. Do not leave the chemical pump on the on position. In the off position the caustic pump will not operate. WASTE OIL INJECTOR PUMP ON/OFF/AUTO SWITCH This switch is usually in the AUTO position, where as the pump operation is

interlocked to minimum & maximum incinerator temperature status and other interlocks; in the OFF position the WASTE OIL INJECTOR PUMP will not run; When in the ON position the WASTE OIL INJECTOR PUMP will run for a timed maximum of 120 seconds, regardless of system status or control interlocks. This pump supplies waste oil to the incinerator secondary waste oil injector. A low level switch located at the tank will stop pump operation if waste oil tank level is low.

DRAFT CONTROL DAMPER CLOSE / AUTO/ OPEN This switch is usually in the AUTO position which permits the position of the draft control damper on the ID Fan outlet to automatically adjust according to incinerator nagative pressure of negative 0.1”w.c. - 0.2”w.c. control pressure range. This switch allows the operator to force the draft damper full open or full closed for testing purposes. CAUTION: Use breaker switch(es) located inside the control panel to disconnect power to burners, pumps, or blowers before servicing equipment. ANNUNCIATOR TEST PUSHBUTTON This button, when pushed in, will sound the audible alarm and cause all the

annunciator lamps to illuminate. ANNUNCIATOR SILENCE PUSHBUTTON This button, when pushed in, will silence the audible alarm. Any additional alarm conditions will again sound the audible alarm. 5 HOPPER SPRAY PUSH TO ACTIVATE PUSHBUTTON This button, when pushed in, will energize the waste hopper water spray solenoid valve. The hopper spray may be manually activated by opening the bypass valve which is parallel to the waste hopper water spray solenoid valve. HYDRAULIC SYSTEM AUTO DRIVE SEQUENCE (WASTE FEED CYCLE): The auto forward sequence is set in motion by a combination of several factors: 1) charge timer counting down and locking at zero. 2) closing of the waste hopper lid by the operator 3) closing of incinerator feed interlocks, which may include temperature limits, purge cycle, stack cap proven closed, scrubber interlocks, bag house temperature interlocks, and burner controls. 4) hydraulic system switch in the AUTO position. The Sequence HOPPER LID CLOSES - by operator using control panel button SYSTEM proves all feed interlocks including time, temperature, and door status interlocks mentioned above. LOWER ASH RAM EXTENDS The lower ash ram extends until the full extend limit switch LS6 is activated, or until the stroke timer TD-6 (inside control panel) times out, which ever occurs first. A full stroke of the ash ram is usually not required. LOWER ASH RAM RETRACTS FULLY UPPER ASH RAM EXTENDS The upper ash ram extends until the full extend limit switch LS8 is activated, or until the stroke timer TD-7 (inside control panel) times out, which ever occurs first. A full stroke of the ash ram is usually not required. UPPER ASH RAM RETRACTS FULLY FIRE DOOR OPENS

CHARGE RAM EXTENDS FULLY The waste feeder control system senses the force being applied to drive the charge ram forward, if this force surpasses a preset limit, the AUTO UNJAMMING sequence is engaged, reversing the ram for a timed period and then returning the waste feeder to the AUTO FORWARD sequence. The auto reverse sequence is initiated when the charge ram reaches the full extend position. CHARGE RAM RETRACTS to a position "CLEAR OF FIRE DOOR" and stops. FIRE DOOR CLOSES If fire door fails to fully close, the auto recycle sequence is engaged, reopening the fire door and recycling the ram. The auto recycle sequence will remain engaged until the obstruction is cleared and the cycle is completed. CHARGE RAM fully retracts. HOPPER LID opens (automatic). 6 HYDRAULIC SYSTEM AUTO DRIVE SEQUENCE, continued: ASH CONVEYOR runs FORWARD FOR A TIMED PERIOD (TD-8), if enabled. MIST SPRAY MIST SPRAYERS (six units installed in the waste hopper) are cycled under the following conditions: 1) sprayers remain engaged for a timed cycle following the closing of the fire door 2) sprayers are engaged by operator pressing the HOPPER SPRAY PUSH TO ACTIVATE PUSHBUTTON 3) sprayers are activated by a temperature sensor built into the wall of the waste hopper which triggers the water spray solenoid valve above 160°F 4) sprayers may be activated by opening the bypass valve in the water line 20-100 psi of water pressure is acceptable. WASTE FEEDER(LOADER) DISABLED ALARM ALARM feature is designed to alert the operator that the waste feeder has jammed and is not successfully correcting the problem on itʼs own. If waste feeder DISABLED alarm is annunciated, the HYDRAULIC SYSTEM switch is switched to the MANUAL position, which should immediately be followed by correcting the waste feeder problem using manual hydraulic switches.

Note: In a waste feeder disabled alarm situation, the first priority should be to secure the fire door in the closed position. Note: Hydraulic directional valves may be actuated manually if necessary by pressing the “button” which is approximately 1/8” in diameter and is located in the center of each hydraulic directional valve solenoid. INCINERATOR CONTROL SYSTEM SEQUENCE The operator will check that the fire door is closed, check that the primary chamber access door is closed, check that the secondary chamber access door is closed, and check that the waste feeder hopper lid is open. The system will not start if these minimum conditions are not proven. The operator then switches the hydraulic system switch to the auto position. The operator rotates the SYSTEM START key. After all limits are proven the MAIN combustion air blower, burner combustion air blower will start and begin the PURGE cycle. The burner combustion air blower will not shut off until the incinerator shuts itself off at the end of the dayʼs operation. The MAIN combustion air blower will shut off at the end of the purge cycle and will not restart until the initial load of waste is injected into the incinerator. The bag house and wet scrubber ID fan and heat exchanger cooling fan begin operation at this time. 7 INCINERATOR CONTROL SYSTEM SEQUENCE, continued: During the PURGE cycle the primary and secondary combustion air manifold dampers(2) open for approximately three minutes prior to ignition of the incineratorʼs burners. The preheat cycle immediately follows the purge cycle. In the event the primary temperature is above 1000°F at the time of start up the purge cycle will be skipped. An example of this condition would be following a generator test or following a power generator shutdown. The PREHEAT cycle is indicated by the PREHEAT/ LOW TEMPERATURE LOCKOUT lamp. The preheat cycle is temperature controlled and is maintained until the secondary chamber temperature reaches 1000°C. At this time the incinerator is ready to accept waste. The combustion air dampers close during the preheat cycle.

The INCINERATE lamp will illuminate after the preheat cycle and after the first load of waste is injected into the incinerator. The high pressure BURNER COMBUSTION AIR BLOWER provides combustion air and atomizing air to the three secondary chamber burners and the two primary chamber burners and to the waste oil injector. This high pressure combustion air blower cycles on during the purge cycle and cycles off four hours after the last load of waste is injected into the incinerator. The low pressure MAIN COMBUSTION AIR BLOWER provides combustion air to the secondary chamber air manifold, and all of the primary chamber air manifolds. This combustion air blower cycles on during the purge cycle, off during the preheat cycle, back on after the first load of waste is injected into thge primary chamber, and cycles off four hours after the last load of waste is injected into the incinerator. The PRIMARY COMBUSTION AIR PRESSURE CONTROL VALVE operates on a time delay following the closing of the fire door after each charge. The primary air pressure may be manually adjusted by moving the linkage of the flow control valve. This modulating butterfly damper valve may be initially set to provide 4.0” w.c. manifold air pressure and may require an increase in pressure for improved ash quality or a decrease in pressure for smoke control. The primary combustion air pressure control valve modulates to low pressure / off when the primary chamber rises above 925°C and remains at the low pressure position until the primary chamber temperature cools to 900°C. The primary combustion air valve opens when the incinerator is off line for additional cooling purposes and to help eliminate glowing embers. The SECONDARY COMBUSTION AIR is controlled with a motorized modulating butterfly damper which modulates according to the position of the BIAS AIR POTENTIOMETER and opens as secondary exhaust temperature increases. The temperature increase is a result of, and an indicator of, an increased presence of fuel derived from the waste. Approximately 80% of the waste placed in the incinerator is oxidized in the secondary chamber. Carbon “vapors” driven from the waste in the primary chamber are oxidized in the secondary chamber. The process has potential to produce temperatures in the 3000°F. range especially when the excess air is controlled. 8 INCINERATOR CONTROL SYSTEM SEQUENCE, continued: The SECONDARY COMBUSTION AIR is controlled with a motorized modulating butterfly damper which modulates open as the temperature in the secondary chamber increases. The damper is fully open during the purge cycle.. The air pressure in the secondary combustion air manifold is biased (higher pressure) during a timed period following each charge of waste into the incinerator. The purpose of bias air is to burn the peak flow of hydrocarbons which vaporize from the waste upon initial placement into

the incinerator. Later in the cycle less air is needed and the motorized air damper returns to the normal modulated setting. SECONDARY COMBUSTION AIR As the exhaust temperature rises from 870°C toward 1100°C, the secondary combustion air control damper modulates from 5% open to fully open. Since the secondary diesel burners are modulated off by the mid 1030s°C, then continually rising temperatures indicate an increase in carbon vapor volume being generated in the primary chamber. As such more oxygen is required to oxidize the vapor. The opposite is so as the temperature in the secondary chamber is reduced, less air is needed. SECONDARY COMBUSTION AIR/ BIAS AIR SIGNAL The air pressure in the secondary combustion air manifold is biased (higher pressure) open during a timed period following each new charge of waste into the incinerator. The purpose of bias air is to burn the peak flow of hydrocarbons which vaporize from the waste upon initial placement into the incinerator. This initial peak of hydrocarbon vapor generation will require extra oxygen (air) before either the oxygen cell or thermocouple have time to react and adjust the secondary air damper. This is the purpose of the bias air signal. The bias air value is controlled by the position of the BIAS AIR POTENTIOMETER which is located inside the control panel. The incinerator is so equipped with four(4) air atomized full modulating natural gas / diesel burners. The burners are numbered 1 thru 4. The numbers assigned are based on flow through the incinerator. Primary burner no. 1 is located near the feeder. Primary burner no. 2 is located in the center of the chamber. The secondary burners are accessed from the platform. Secondary burner no. 3 is located on the end above the ash conveyor. Secondary burner no. 4 is located nearest to the stack exhaust connection.

The SECONDARY BURNERS are of the full modulating type which modulate according to the exhaust temperature of the secondary chamber, see chart below. The secondary burners are disabled two hours after waste feeding stops. The fuel/air mixture and rate of input is continuously modulated to provide process heat as required to the secondary combustion chamber to maintain the minimum exhaust temperature. The burners may cycle off during the incineration process if the waste is generating sufficient heat to maintain minimum temperatures. The PRIMARY BURNERS are of the full modulating type which modulates according to the exhaust temperature of the primary chamber, see chart below The primary burners cycle off while the fire door is open and for a timed following each charge of waste into the primary chamber. After the fire door closes and with all other limits satisfied the primary burner no. 3 ignites after a 1 minute delay, burner no. 2 ignites after a 1-1/2 minute delay, and burner no. 3 ignites after a 2 minute delay. The burners cycles off when any access door is opened and while either ash ram is not proven fully retracted.. The primary burners are disabled two hours after waste feeding stops.

Primary chamber climbs above 1100°C. (Primary high temperature lockout) B. Bag house climbs above 205°C. C. Secondary chamber climbs above 1100°C. (Secondary high temperature lockout) D. Secondary chamber falls below 1000° C. (Secondary low temperature lockout) E. Charge timer has not engaged. F. Hydraulic pump controls in manual or off. G. System is off line. H. Stack cap is open I. Any incinerator door is open. J. Wet scrubber low water K. Wet Scrubber low pH

BURNER OPERATION INFORMATION All the primary burners and secondary burners have full modulation of fuel and combustion air. All four burners operate in an identical manner. The main fuel is ignited by a proven gaseous fueled pilot flame. The pilot flame is ignited by an electrical arc fired by the ignition electrode (spark plug) installed on the burner housing. The electrical arc ignites the pilot. The flame is proven by means of an ultra violet light scanner installed on the burner housing. The scanner can only “see” the flame while the pilot or fuel valve is open. The purple colored UV scanner device senses a flame signal to the Honeywell burner controller installed in the control panel. The flame signal may be tested by inserting a DC volt meter lead(s) into the positive(+) and negative(-) test jacks on the Honeywell flame controller installed in the control panel. A steady signal of 1.25 vdc to 5.0 vdc is acceptable. If a low signal is present (under 1.25vdc) or no signal is present. Check the appropriate scanner relays for operation. Check wiring. Check the scanner eye for dirt (wipe only with clean tissue, do not touch the eye.) Check for spark at the ignition electrode. The combustion air and fuel are modulated from high to low fire with a Honeywell damper motor coupled to the combustion air butterfly valve and natural gas butterfly flow control valve based on a 4-20mA analog signal originating in the corresponding temperature controller.

Pilot gas flow is controlled by the pilot gas regulator and pilot gas butterfly valve. The pilot air shall remain fully open at all times. The pilot gas butterfly valve is adjusted to form a small pilot flame. The pilot flame should be maintainable at any burner combustion air pressure. An air purge is supplied to the UV scanner tube to prevent dirt and heat from contacting the UV scanner lens. See specific operating data for the burners and temperature controls at the end of this section. 10

INCINERATOR CONTROL SYSTEM SEQUENCE, continued: After the dayʼs waste is consumed, the operator closes the hopper lid and switches the hydraulic system to manual. Two hours after doing so, the burners will be disabled. Two hours later the incinerator combustion air blower will cycle off. The incinerator system, 4 hours after the last load of waste is injected into the primary chamber is now off line. The COOLING CYCLE lamp will illuminate the final 2 hours of operation.

AIR to AIR HEAT EXCHANGER OPERATION- Gas cooling: The clear waste gases (products of combustion) exit the incinerator relatively clean, smoke free, but at a high temperature, in excess of 1000°C. In order that the emissions from the incinerator are able to meet the EU and US EPA clean air regulations, filtration devices are employed. The maximum inlet temperature of these devices is 200°C. As such as the gases exiting the incinerator are at a much higher temperature than what is allowable in the filtration process, gas cooling is required. The extreme heat is radiated thru the shell of the ductwork to the air to air heat exchanger. The gas temperature is lowered to approximately 750°C by the intial radiation duct work. The air to air heat exchanger is fabricated of high grade nickel alloy. The exchanger section flows ambient cooling air as required to reduce the waste gas temperature to a controlled 150°-180°C as measured at the bag house inlet. A variable frequency drive(VFD) unit reacts to the incoming bag house temperature to control the speed and flow from the cooling air blower. Waste gases thus exit the air to air heat exchanger at a control temperature. The cooling air is heated in the process to approximately 375°C and exhausted to the atmosphere. The base of the air to air heat exchanger is supported by a clean out holding box in whcih gases are turned 180° and in which large particles are collected and deposited in the box. The box and air to air heat exchanger are equipped with access doors for cleaning purposes. Frequency of cleaning is suggested initially each two weeks, until operation determines the frequency of cleaning required. Thi cleaning cycle varies from site to site. An interconnecting unlined stainless steel duct then routes the cooled waste gases to the baghouse inlet.

BAGHOUSE DUST COLLECTOR SYSTEM The baghouse dust collector uses special fabric filters to collect approximately 95-99% of remaining microscopic and larger dust particles and heavy metals that pass through the air to air heat exchanger. The bag house is operated at a temperature sufficient to prevent condensation of acid compounds in its interior surfaces. The dust collector contains approximately 260 pcs of a fabric “bag” which is 15cm in diameter and 180cm in length. The gases pass through the exterior side of the bags and exit at the end of the interior side. Filtered particles collect on the outside of the bags. A rotary screw air compressor and air dryer supply compressed air to teh baghouse for bag cleaing. On a user adjustable timer control automatic reverse pulse of compressed air is applied to the inside of the bags to clean the collected dust from the outside surface of the bags. This reverse pulse dust drops to the base of the baghouse hopper. Once each day a manual slide valve is opened to drop the collected dust into a drum for proper disposal.

11 INCINERATOR CONTROL SYSTEM SEQUENCE, continued: WET SCRUBBER OPERATION The purpose of the scrubbing system is to remove acid producing compounds from the waste gas stream. This scrubbing apparatus is required under this contract according to emission performance data. Waste gases exit the baghouse and enter a gas quenching chamber where the temperature is reduced to 80°C. Scrubber liquor is sprayed into the quench chamber using several 3/4 npt clog resistant wide angle spray heads rated at 10 gpm each operating at 30 psi. The scrubbing process begins at this point although the primary purpose of the gas quenching chamber is for cooling purposes. Excess scrubbing liquor (scrubber water) drains back to the tank in the same duct as the gases. Cooled waste gases enter the scrubber tower above the tank and below the separator plate. The separator plate is the point where acid producing compounds are neutralized and separated from the waste gas. The scrubber has one separation plate where approximately 99% of acid pollutants are removed. The separator plate is perforated with approximately 1500 directional holes approximately 5mm in diameter. The top side of the plate is continuously flooded with scrubbing liquor. Waste gases pass up through the plate from the bottom side and are propelled though the scrubbing liquor. The liquor level is maintained at about 10cm by 1-1/2 npt clog resistant wide angle spray head rated at 25 gpm operating at 30 psi. Excess liquor overflows the separator plate and drains back to the tank. The pH of the liquor is maintained by an injection of 50% solution of caustic which is pumped on demand using a common peristaltic pump or “tube” pump. The pH level

of the liquor is maintained at 6 to 7. The process of neutralizing acids creates salts and increases the density of the liquor, this is further complicated by the evaporation of water in the liquor. For this reason, the liquor tank is blown down to the drain via a 2” automatic drain valve. The drain valve close time TD9 and open time TD10 are user adjustable via timers. TD9 controls the valve closed time, typically two hours. Timer TD10 controls the blowdown valve open time, typically 2-5 minutes. In the event the temperature of liquor rises above 85°C, fresh water will be introduced to the tank. Excess water in the tank will pass to the drain via the overflow piping. Fresh water is introduced into the scrubber as required by float activated switches. The water feed valve is controlled by a level switch and certain commands from the PLC. The cleaned waste gases then are routed to the Induced draft fan inlet and blown up the stack. Water vapor will condense on the walls of the stack and drain back to the tank. The outlet of the scrubber stack is equipped with a trap to prevent condensed water from being “blown” into the surrounding area. The scrubber liquor to the quench chamber and the separator plate is supplied by two(2) 3 hp pumps, each capable of delivering 60 gpm at 20 ft. of head. The pump is capable of passing solids up to 0.375 inches in diameter. The 3/4” spray nozzles will pass objects up to 0.28 inches in diameter. And the 1-1/2” spray nozzles will pass objects up to 0.62 inches in diameter.

12 WET SCRUBBER OPERATION, continued: A motorized butterfly valve is positioned in the final exhaust stack to control the rate of final exhaust gas flow. The damper motor is responding to changes in pressure in the primary chamber of the incinerator. During high flow demand periods the draft damper opens which increases the scrubberʼs capacity for waste gas flow from the incinerator. And, during lower flow demand periods the draft damper closes which decreases the scrubberʼs capacity for waste gas flow from the incinerator. After the dayʼs waste is consumed, the operator switches the closes the hopper lid and switches the hydraulic system to manual. Two hours after doing so, the burners will be disabled. Two hours later the scrubber, bag house, and incinerator blowers will cycle off and the stack cap will open. The incinerator system, 4 hours after the last load of waste is injected into the primary chamber is now off line. The COOLING CYCLE lamp will illuminate the final 2 hours of operation.

NOTE: Mixing of caustic soda is not required. Purchase the caustic soda(NaOH) from a chemical supplier in a 50% solution. When one drum is empty, pull the plastic suction tubing from the empty drum and place it inside the full drum. Make sure the tubing goes to the bottom of the drum. It is recommended that the ph sensor is recalibrated once per week minimum to prevent damage to teh wet scrubber apparatus. DO NOT OPERATE THE WET SCRUBBER WITH OUT SUPPLY OF CAUSTIC SODA(NAOH) OR WITH CAUSTIC SODA IN FROZEN STATE, EQUIPMENT DAMAGE WILL RESULT. IF REQUIRED, DURING COLD WEATHER APPLY HEAT TO THE CAUSTIC SODA CONTAINER TO PREVENT FREEZING OF THE CAUSTIC SODA SOLUTION. CAUTION: Do not touch the caustic or suction tubing with your bare hands. Chemical burns will result. Wear gloves, safety glasses and protective clothing when handling caustic drums or tubing from with in the caustic drum. NOTE: DARK Visible emission at the stack is usually associated with over charging the incinerator, excessive air leakage into the primary chamber, or failed combustion air delivery components to the secondary chamber. Seek factory assistance in the unlikely event that visible emission is experienced on a routine basis. 13 ANNUNCIATOR ALARMS AND CORRECTIVE MEASURES: PRIMARY BURNER No. 1 FLAME FAILURE: Primary burner has failed to light. Press PRIMARY BURNER No. 1 RESET button up to three times waiting 10 seconds before pressing a 2nd or third time. Confirm the alarm goes off an the burner attempts to relight after pressing the RESET button.

The ash ram has failed to return to the full retract position. This condition may cause permanent damage to the ash ram tubes. Check ash ram directional valves, position proving switches, and hydraulic pump or e-stop switches. Take the appropriate action to retract the ash ram from the primary chamber. The primary burner will not fire while in this condition. LOADER DISABLED ALARM This alarm feature is designed to alert operator that loader has jammed or failed the auto loading sequence in some form. If LOADER DISABLED alarm is annunciated, the HYDRAULIC SYSTEM switch is switched to the MANUAL position, which should immediately be followed by correcting loader problem using manual hydraulic switches. In a loader disabled situation, the first priority should be to secure the fire door in the closed position. Then check for obstruction, check limit switches by proving the physical position of each component and check that the appropriate lamp on the control panel is illuminated indicating that the limit switch or position sensor is working. Check hydraulic pump pressure. Check hydraulic pump overload relay. Check circuit breaker for hydraulic pump. Or Seek service. SCRUBBER TANK LOW FLUID LEVEL The liquid level in the scrubber tank is low. This caused the liquor pump to stop operation, the stack cap to open, and the feed system to lock out. Check output relays, wiring, water supply pressure, and water supply valves, and water level control switch. SCRUBBER LOW pH The liquor in the scrubber tank is becoming acidic. The caustic pump has stopped operation or the caustic solution barrel is empty. Check caustic supply barrel level, output relays, pump tubing, wiring, and pump switch. SCRUBBER INDUCED DRAFT FAN HIGH TEMP The inlet temperature of the scrubber fan has exceeded 180°C. This caused the stack cap to open, and the feed system to lock out. Check the water level floats, fan temperature probe, scrubber tank drain valve, scrubber liquor pump operation. CHECK STACK CAP Stack cap has not fully closed. This prevents the system from running. Check hydraulic system operation, stack cap open pushbutton position, stack cap limit switches. Or the stack cap did not fully open when commanded to do so. LOW DRAFT The pressure with in the primary chamber is too high. This caused the stack cap to open, primary burner and combustion air to shut off, and the feed system to lock out. Check draft damper operation by switching full open and closed. Check that heat exchanger is not plugged or plugging, cleaning may be required. ID FAN OVERLOAD The APC ID fan is supposed to be running, but one or more running interlocks has opened. The interlocks include high cyclone temperature, motor overload, and the

variable speed drive control. Check for variable speed drive operation. Shut off ID FAN control panel switch and then turn the switch on again, and attempt to restart after investigating. 15 ANNUNCIATOR ALARMS AND CORRECTIVE MEASURES, continued: COOLING OVERLOAD The COOLING fan is supposed to be running, but one or more running interlocks has opened. The interlocks include, motor overload, and the variable speed drive control. Check for variable speed drive operation. Shut off COOLING FAN control panel switch and then turn the switch on again, and attempt to restart after investigating. ASH CONVEYOR OVERLOAD The ash conveyor shaft rotation switch did not/make/break while the ash conveyor was commanded to run. Check that the needle valve is not closed or closed to far. Check that the hydraulic system is generating pressure. Check that the hydraulic directional valve is opening (by observe the hydraulic hoses “jumping” at the conveyor motors when the conveyor is commanded to run is given). Check that the conveyor will run reverse then forward again. Forward and reverse operation will usually clear a jamb. BAG HOUSE HIGH TEMP The inlet temperature of the cyclone fan has exceeded 205°C. This caused the stack cap to open, and the feed system to lock out. Check the operation of the heat exchanger cooling fan.

16 MAINTENANCE DAILY OPERATE ash conveyor one full chain revolution every day CHECK fly ash level in HEAT EXCHANGER BOX, empty as required. Open Baghouse hopper slide gates & check fly ash level in hopper drums empty as required. WEEKLY: CALIBRATE pH sensor using pH 4, 7, 10 test solutions CHECK hydraulic system for leaks and CHECK hydraulic fluid level. DO NOT USE CONVENTIONAL HYDRAULIC FLUID. USE ONLY FIRE RETARDANT WATER GLYCOL HYDRAULIC FLUID CLEAN debris from beneath base of fire door ROD THRU external primary air jets on the lower hearth level, there are multiple air jets per manifold, there is one air manifold on each side of the lower hearth. Use 1/2” diameter x 12” length cleaning rod* CHECK for accumulation of fly ash under and inside heat exchanger. The frequency of this check may have to be altered as required after operation is established. MONTHLY: CHECK and change as necessary rope gasket beneath base of fire door. CHECK and add ringes to ash conveyor packing as required, do not overtighten packing. Add antiseize past to ash ram tube surface with new packing to prevent sticking and tearing of packing. VACUUM primary chamber and apply coating of Satanite mortar as required. Coat the hearth with a sacrificial layer or mortar to prevent

glass adhesion to the refractory lining. Experience will determine if this practice should continue. ROD THRU internal primary air jets on the two upper hearth level, there are fifteen air jets per manifold, there are three air manifolds on per hearth, there is one air jet in the center and seven jets on either side of center jet, On the middle hearth the jets spaced 4” apart, On the upper hearth the jets spaced 4.75” apart, use 3/8” diameter x 12” length cleaning rod CHECK output pressure of primary chamber combustion air manifold CHANGE as necessary rope gaskets on primary chamber door(1), and waste feeder door(4) SEMI- ANNUALLY: GREASE bearings on all blowers: 17 HYDRAULIC SYSTEM NOTES NOTE: Hydraulic directional valves may be actuated manually if necessary by pressing the “button” which is approximately 1/8” in diameter and is located in the center of each directional valve solenoid. If hydraulic components appear to move in an irregular fashion, check that speed/flow control valves are not closed or partially plugged. The debris that occasionally collects in the valve my be flushed to the tank by fully opening the valve and operating the cylinder. Following flush, readjust the valve until the cylinder runs at the desired speed. Speed is adjustable in both directions for the hopper lid cylinder. ASH CONVEYOR NOTES Max continuous hydraulic operating pressure at the motors is 1300 PSI. IMPORTANT- The ash conveyor chain is designed to run underwater. To prevent seizing of the chain due to dried solids in the pin assemblies: •Be certain the conveyor chain moves everyday.

•If the incinerator is offline for an extended period then have operators run the conveyor chain at least one full rotation each day, with water in the tank. •DO not allow chain and tank to totally dry out with out a thorough rinse of the chain link pins.
