CONDENSATE RECOVERY SYSTEM MODIFICATIONS

NORMAL Sequence of Operation Condensate Return Boiler Feed SystemDescription:

REFER TO DRAWING M-6.02 FOR DESCRIPTION AND FLOW DIAGRAM OF NORMAL OPERATION

1. Low pressure (0-15 psig) and medium pressure (approximately 45 psig to 70 psig) steamsystem condensate returns are collected in mechanical spaces at the various buildingsthroughout campus and pumped at varying intervals back to the central plant as PumpedCondensate (PC).

2. High pressure (approximately 70 - 150 psig) steam condensate return is usually piped fromthermodynamic trap discharge directly back to the central plant as High Pressure Return(HPR) from mechanical rooms and also from steam piping traps in manholes. In some cases,HPR is discharged to flash tanks in building mechanical rooms then pumped back as PC.

4. The North HPR and South HPR cond loops are piped directly to a high pressure return ventedflash tank. The high temperature of the HPR flashes to steam as it hits the vented tank. Theflash tank discharge is piped from a vented loop at midway up the flashtank to the inletcondensate header of the surge tank.

5. PC coming back to the central plant from various sources will lift to a header then dropsdown into the vented atmospheric surge tank to be installed on the mezzanine. Any flashsteam is vented from the surge tank. Makeup water is to be added at the surge tank whenthe surge tank level drops. A Low Pressure (LPC) mix of condensate and makeup water (asrequired) is transferred from the surge tank through variable speed, high temperature rated,transfer pumps (TP-1&2) matched to the inlet valve flow and pressure requirements of theDeaerator (DA).

6. The DA preheats the condensate and removes the oxygen and dissolved gasses and leavesthe DA as Boiler Feed Water (BFW).

7. The preheated BFW drops to the three Boiler Feed Water Pumps (BP-1,2,3) where it ispumped back to the boilers.

DISABLE PUMPS WHEN FLUID LEVEL IS TOO LOW.

7. CONDENSATE DROPS TO TRANSFER PUMPS.

8. THE ACTIVE TRANSFER PUMP PUMPS CONDENSATE TO DEAERATOR. THE DEAERATOR IS SLIGHTLY

PRESSURIZED AND HAS RESTRICTED VENT.

9. SODIUM SULFITE IS ADDED AT THE DEAERATOR.

10. LOW PRESSURE STEAM IS ADDED TO THE DEAERATOR.

11. THE DEAERATOR PREPARES THE CONDENSATE FOR RETURN TO THE BOILER.

12. OVERFLOW DRAINAGE IS THROUGH THE SURGE TANK AND FLASH TANK OVERFLOW OPENINGS AND

PIPING AND OR THE DA OVERFLOW TRAP. OVERFLOW DRAINAGE CAN ALSO OCCUR THROUGH THE

HEADER PIPE SURGE OVERFLOW DRAIN LINE, BUT IS NOT LIKELY DURING NORMAL OPERATION.

13. THE BOILER FEED WATER IS DISCHARGED FROM THE DEAERATOR TO THE BOILER FEED PUMPS.

14. THE ACTIVE BOILER FEED PUMP PUMPS THE BOILER FEED WATER TO THE ACTIVE BOILERS.

15. BOILERS CREATE THE STEAM THAT IS DISTRIBUTED THROUGHOUT THE CAMPUS.

CONDENSATE RECOVERY SYSTEM SURGE TANK BYPASS OPERATION

DESCRIPTION OF OPERATIONBYPASS ARRANGEMENT.

NOTE: BYPASS OPERATION IS FOR EMERGENCY USE WHEN THE SURGE TANK IS NOT AVAILABLE DUE TO

MAINTENANCE OR MALFUNCTION. THIS MODE DOES NOT HOLD THE CONDENSATE LONG AND MAY BE

STRESSFUL ON THE TRANSFER PUMPS DUE TO HIGH TEMPERATURE OF RETURNING CONDENSATE. THE

VENTED OVERSIZED 10" LPC PIPE AND AND HIGH PRESSURE RETURN FLASH TANK PROVIDE SOME

DEGREE OF PROTECTION, BUT OPERATING IN THIS MODE SHOULD BE KEPT TO A MINIMUM.

BASIC DESCRIPTION:

1. SURGE TANK IS VALVED OFFLINE.

2. HPR RETURNS TO VENTED FLASH TANK.


SURGE TANK HEADER BYPASSING SURGE TANK TO 10" LOW PRESSURE RETURN HEADER, WHICH IS

VENTED TO THE FLASH TANK VENT.

4. FLUID SENSOR IN HEADER ENABLES TRANSFER PUMPS. POSITION TO ALLOW ADEQUATE TIME TO

DISABLE PUMPS WHEN FLUID LEVEL IS TOO LOW.

5. CONDENSATE DROPS TO TRANSFER PUMPS.

6. THE ACTIVE TRANSFER PUMP PUMPS CONDENSATE TO DEAERATOR.

7. MAKEUP WATER IS ADDED AT THE DEAERATOR.

8. SODIUM SULFITE IS ADDED AT THE DEAERATOR.

9. LOW PRESSURE STEAM IS ADDED TO THE DEAERATOR.

10. THE DEAERATOR PREPARES THE CONDENSATE FOR RETURN TO THE BOILER.

11. OVERFLOW DRAINAGE IS THROUGH THE FLASH TANK OVERFLOW OPENING AND PIPING AND OR THE

DA OVERFLOW TRAP. OR THROUGH THE HEADER PIPE SURGE OVERFLOW DRAIN LINE.

12. THE BOILER FEED WATER DROPS FROM THE DEAERATOR TO THE BOILER FEED PUMPS.


14. BOIELRS CREATE THE STEAM THAT IS DISTRIBUTED THROUGHOUT THE CAMPUS.
