Air pressure transmitter 11 and air control valve 12 are sequentially installed on air hose 1.
Further include PLC controller, gas meter 31, gaseous-pressure transmitter 33, gas leakage transmitter 35, infrared ray
Coal gas detection instrument 37 and air pressure transmitter 11 will detect that signal sends PLC controller to, and PLC controller controls combustion gas tune
Save valve 32, the first gas cut off valve 34, the second gas cut off valve 36, ignition cut valve, blow valve 41, nitrogen stop valve 21 and sky
Gas regulating valve 12 opens and closes.
The working process of the utility model is as follows：
One, when opening burner 7：
1st step：When gaseous-pressure transmitter 33, air pressure transmitter 11 detect that pressure is higher than setting value, operator
After member presses start button, blow valve 41 must be electrically turn off.Whether it is more than to set that gas leakage transmitter 35 detects pressure to go up after 15S
Definite value represents the first gas cut off valve 34 or nitrogen stop valve 21 does not leak if be no more than.If it is more than setting to go up
Value, PLC controller sends out failsafe valve, and warning output, while each valve is in a state of nature.
2nd step：First gas cut off valve 34 close after electric opening 2S, at this time gas leakage transmitter 35 should and combustion gas
Pressure transmitter 33 is consistent, keeps 15S.If gas leakage transmitter 35 is not below setting value, illustrate the second gas cut off valve
36 is normal.If gas leakage transmitter 35 illustrates that 36 failure of the second gas cut off valve has interior leakage situation less than leak detection setting value, and
Warning output, while each valve handles reset condition.
3rd step：Air control valve 12 is opened automatically to ignition position and opens 5%, and boiler high-energy ignition transformer, which must be established by cable, to be begun to beat
Fire, opening ignition of the boiler stop valve 51, while flame detector 8 execute next step after detecting flame.If fire defector after 5S
Device 8 does not detect that flare up fire, PLC controller think loss of ignition, and each valve is in a state of nature.
4th step：First gas cut off valve 34, the second gas cut off valve 36 are opened, and 7 turns of automatic runnings of burner adjust combustion
Gas regulating valve 32 carrys out adjustment of combustion gas flow, while air control valve 12 is automatically adjusted according to gas flow.
Two, when stopping burner 7：
1st step：After operating personnel press stop button, the first gas cut off valve 34, the second gas cut off valve 36 close, are empty
Gas regulating valve 12 is opened after certain aperture carries out purging 2min and is automatically closed.Blow valve 41 is opened, and nitrogen stop valve 21 is opened
Nitrogen stop valve 21 is closed after 2S.
2nd step：As long as the pressure that gaseous-pressure transmitter 33, air pressure transmitter 11 detect after normal operation is low
In setting value, 8 no signal of boiler flame detector, the first gas cut off valve 34, the second gas cut off valve 36 are closed, burner 7
Out of service while alarm indication.Detect that combustion gas is not above height and gives the correct time in infrared gas combustion detector 37, air control valve
12, which open certain aperture, is purged.Detect that combustion gas is given the correct time more than height in infrared gas combustion detector 37, air control valve 12
It closes, nitrogen stop valve 21, the second gas cut off valve 36 opening purge pipeline, ensure safety, until infrared ray fires
Gas detector 37 disappears.
3rd step：As long as the first gas cut off valve 34 is closed, and flame detector 8 is without flame alarm alarm signal
Number, PLC controls think that burner 7 handles dead ship condition, when infrared ray coal gas detection instrument 37 detects that combustion gas is given the correct time more than height, put
Empty valve 41 is closed, and nitrogen stop valve 21, the second gas cut off valve 36 opening purge pipeline, until infrared gas combustion is examined
It surveys instrument 37 to disappear, nitrogen stop valve 21, the second gas cut off valve 36 are closed after the completion, and blow valve 41 is opened.
