The EMB burners develop the maximum capacity in stoi-

chiometric ratio with 45mbar of air pressure. This implies

the use of low prevalence blowers which are also inex-

pensive; the setting is simplified due the special differen-

tial pressure plugs that allow the measurement of air and

gas flow.

PARAMETER CAPACITY AND FLAME LENGTH

DESCRPTION

The EMB burner ignition takes place through a high ten-

sion discharge obtained via an electrode and the detec-

tion is performed by another electrode, or by UV scanner

(in block holder version).

The adoption of flame control systems is highly recom-

mended in all plants operating at temperatures lower

than 750°C (UNI EN746/2 Regulation).

The flame lengths and velocities are approximate, they

refer to burners fed by natural gas that are placed in open

air and function in stoichiometric ratio at nominal capaci-

ty.

In special applications, mono-electrodes for the ignition

and flame detection are used or else an electrode for

flame ignition and a UV photocell for the flame detection

is used.

The EMB burners are "nozzle mix" type burners. The fuel

and combustive agents are mixed at the combustion head

to avoid dangerous flame flashbacks. Furthermore, the

special shape of the combustion head allows regulation in

stoichiometric ratio as well as in air excess or gas excess.

The burners can work also with preheated combustion air

up to 550°C.

WARNINGS

¾¾ The EMB burner ignition must always be carried outat minimum power, modulating towards the maximum,

facilitating the ignition and reducing the outlet overpres-

sures. Thus it is opportune to use slow opening solenoid

valves on the fuel line.

¾¾ The passing from minimum to maximum power andvice-versa, must be gradual and not instantaneous. In

double stage regulations, the use of MRBV regulation

valves (data sheet E1302) is suggested.

¾¾ For all low temperature applications (up to 750°C),the burner ignition and the fuel gas solenoid valve com-

mands must be performed via a certified burner control

device.

¾¾ To avoid possible damage to burners, make sure thatthe blower does not send them air that may be fouled by

combustion products, oils, solvents or other. To avoid

these phenomena from taking place, possibly install the

blower or the suction duct outside the establishment and

far from the exhaust pipes.

¾¾ Check the correct connection of the feeding lines afterinstallation. Before switching the burner on, check that

the combustive air and fuel gas pressure values are cor-

rect (Pag.05).

¾¾ The burner can only function within the indicatedpower range. Functioning at lower or higher powers

could compromise the burner performance as well as its

life span. In which case, the general warrantee condi-

tions will automatically expire and ESA will not be held

responsible for any damage to persons or things.

¾¾ If there is trouble with other devices during the burnerstart up phase, use the connector with anti disturbance

filter for the high-tension (HT) cable connection of the

ignition electrode.

¾¾ Avoid burner ignition close to each other so as not toheat the ignition command system devices (solenoid val-

ves and transformers). Prewash time lapse + first safety

time lapse + min. of 5 sec. = time lapse between one igni-

tion and another. (however, do not attempt more than 2

ignitions during a 30sec. time lapse).

¾¾ Make sure the power supply is TURNED OFF whenintervening on the burner and its devices. In case of bur-

ner malfunctioning, follow the indications in the

'Maintenance' chapter of the present manual or contact

ESA-PYRONICS assistance.

¾¾ Any modification or repair done by third parties cancompromise the application safety and automatically

cause the general warrantee conditions to expire.

EMB - E3004 rev. 09 - 18/01/18


INSTALLATION

The EMB series burners are supplied with a special fur-nace wall fixing flange. The light obtained for the burnerhousing must leave open space around the burner. Thisspace has then to be filled with ceramic-fibre.

For the installation carefully follow the instructions below:

1 - Place the EMB burners far from heat sources and pro-ducts such as: liquids, solvents or corrosive gases.

2 - Make sure that the housing dimensions and thedistance between the centers of the feeding pipes corre-spond to what is specified in the "Overall dimensions"chapter.

3 - Assemble the burner on the furnace wall (pos. 01)interposing a ceramic fibre gasket between the atta-chment flange and the furnace wall (pos.02) *. During theburner insertion phase check that the insulation previou-sly wrapped around the outside is not altered nor dama-ged. Once the spacer has been fixed onto the furnace,from the inside of the combustion chamber, seal any pos-sible cracks that may be left between the wall and thespacer with ceramic fibre.

4 - Connect the combustion air and fuel gas inlet piping,interposing, if possible, dilation joints in AISI.

5 - Connect electricity to the ignition electrode and to theuv-scan detector making sure not to pass the conductorsnear heat sources.

6 - Check that the burner body and all its metallic ele-ments are earthed with appropriate conductors.

7 - The connecting cable from the ignition transformer tothe electrode must be specific for high tension and notscreened. It must not be more than 1 metre long; other-wise the ignition transformer must be positioned near theburner. The high tension cable must be placed far fromthe power cables and not in metallic ducts. Ideally itshould be left in open air.

8 - For further information please consult the technicaldata sheet concerning the ignition transformers.

9 - Connect electricity to the ignition electrode and to theuv-scan detector making sure not to pass the conductorsnear heat sources.

NOTE: * The furnace wall seal, unless specifically reque-sted by the customer, is not included in the burner supply.

START-UP - SETTING

PREMIX AIR FLOW SETTING WHERE SCHEDULED (LPG BURNERS)

The procedures indicated in the following chapter must

be carried out by expert technicians. The non-observan-

ce of the instructions given can provoke dangerous con-

ditions.

1 - Check that the combustion air pressure exiting the

blower and the combustive fuel feeding pressure are both

within the allowed range.

2 - Adjust the working pressure and the safety device

pressure of the combustion plant, whether there is one

per burner or one for the whole plant i.e. gas pressure

reduction gear, block valve, relief valve, pressure swit-

ches etc. Simulate the intervention of all the safety devi-

ces including the intervention of the safety over tempera-

ture, checking that the fuel safety block devices act pro-

perly.

3 - Place the motorized air regulation valve in its maxi-

mum opening position and, via the gate valve, regulate

the inlet air pressures to the burner, referring to the

values indicated in the "burner performance" chapter for

the maximum capacities (pag.05).

4 - Place the motorized air regulation valve in its mini-

mum opening position and regulate its opening to obtain

(in burner and ejector inlet) the relative minimum power

pressure.

5 -Activate the burner control device and attempt the igni-

tion until the burner switches on. While attempting to igni-

te the burner, act on the gas adjustment valve and, star-

ting from the totally closed position, open it gradually until

the burner ignites.

6 - Fully open the air regulation valve and adjust the maxi-

mum fuel capacity via the gas adjustment valve, checking

the differential pressure created on the calibrated gas

flange.

7 - Double check that, at minimum and maximum power,

the burner inlet pressure corresponds to the values in the

in the 'Parameter capacity" chapter. These values may be

different depending on whether the burner is on or off.

8 - If necessary, with all burners turned onto the same

power, analyse the combustion products in the chamber

(where possible).

9 - Repeatedly attempt ignition at minimum burner power,

with maximum amplitude, to check the ignition reliability

and flame stability during the adjustment.

The premix line is supplied with the LPG burners. The

setting must be carried out with burner off and in mini-

mum flow conditions. The premix line must be fed by an

inlet necessarily placed upstream the air flow regulation

valve, whether it is in zone or interlocked by the main bur-

ner.

1. Place the burner in the minimum combustion air flow

conditions.

2. Open the premix air tap.

3. Regulate the micrometric pin valve according to the fol-

lowing conditions:

4. Check, however, that at minimum power, the burner

does not create black smoke on the combustion head

and on the electrodes. In case this should occur, increa-

se the premix air setting.

For correct dismantling and better maintenance of the

EMB burner, meticulously follow the instructions below

with the plant turned off.

BURNER-SHUTDOWN

For correct dismantling and better maintenance of

the EMB burners, meticulously follow the instruc-

tions with the plant turned off. In shutdown condi-

tions of the burner refer to the burner control device

indications and to the relative manual to identify the

cause. The main cases are indicated here below:

¾¾ Illegal flame detection: the shutdown is due to an ille-

gal flame detection during the phases prior to ignition or

after the turning off. The causes are within the detection

system (broken or faulty sensor or presence of humidi-

ty), or in the gas draw from the solenoid safety valve,

which allows the burner to remain turned on.

EXTRAORDINARY MAINTENANCE

¾¾Failed ignition: shutdown is caused due to the fact

that no flame has been created during the starting pro-

cess. The causes can be found in the start-up system

(spark absence, faulty electrodes or incorrect position),

in the bad setting of the fuel and combustion flow or in

the detection system (faulty sensor or interrupted

cables). More precisely, in the first two cases the flame

is not ignited, while in the last case the flame is created

but the burner control device is unable to detect it.

¾¾Flame signal loss: shutdown due to the loss of flame

signal during the normal functioning of the burner. The

causes can be found in the combustion air flow adju-

stment (rapid flow variations, adjustment out of allowed

range). They can also be found in the detection system

(faulty, dirty or badly positioned sensors).
