Abstract
Provided is a safe ignition device for combustor. The ignition device comprises an igniter, a pilot fire combustor and a control circuit, wherein, the control circuit is provided with a flame ion detection electrode, a detection probe of which is arranged near an igniting electrode of the igniter that is arranged at an upper part, an air inlet pipeline is provided with a pilot fire combustion gas control solenoid valve which is connected with the control circuit, and the control circuit is arrange to be connected with a main fire combustion gas feeding solenoid valve which is used for controlling a main combustion gas pipeline of the combustor. The ignition device and ignition method provided in the invention enable effective eradication of deflagration of single-stage ignition caused by unlatching of a large displacement combustion gas control solenoid valve.
Description
Technical field:
The invention belongs to the firing technique field in gas furnace, what be specifically related to is a kind of igniter of burner.
Background technology:
Be widely used in gas burner safety control circuit at present and mostly be single-stage flame combustion control mode.This control mode is adapted to small-power burning heating equipment and uses, but there will be combustion gas deflagration phenomenon to high-power firing equipment owing to discharging in a large number in ignition point combustion gas, has a strong impact on security when fuel gas buring is lighted.
Summary of the invention:
The object of this invention is to provide and a kind ofly can overcome the igniter of the burner of the combustion gas deflagration phenomenon of high-power burning heating equipment and use the ignition method of this kind of igniter.
The present invention solves the technical scheme that its technical problem takes: a kind of igniter of burner, key is that described igniter comprises igniter, kindling material burner and control circuit, described described control circuit is provided with a flame ion detecting electrode, the probe of described flame ion detecting electrode is arranged on the top of kindling material burner, the ignitor of described igniter is arranged on top, described air inlet pipeline is provided with a kindling material combustion gas Controlling solenoid valve, described kindling material combustion gas Controlling solenoid valve is connected on control circuit, described control circuit also arranges and is connected with a main fiery gas supply magnetic valve, main fiery gas supply magnetic valve is used for the main combustible pipe road of control combustion device.
Described igniter is crosspointer igniter.
The probe of described flame ion detecting electrode crosses above main burner from the outlet of kindling material burner.
The present invention also provides a kind of and uses the ignition method of above-mentioned igniter: described method comprises step:
1), the power supply of igniter connects, and ignitor produces electric spark;
2), after igniter is connected interval first interval time, kindling material combustion gas Controlling solenoid valve is opened, spark ignition kindling material burner; If the probe of flame ion detecting electrode can't detect burning signal after kindling material combustion gas Controlling solenoid valve is opened within the first detection time, kindling material combustion gas Controlling solenoid valve will be closed.
3), when the probe in detecting of flame ion detecting electrode is to lighting kindling material burner by after the signal lighted, open main gas control valve, main burner is sent in combustion gas, main burner is lighted by the flare of kindling material burner, and closes kindling material combustion gas Controlling solenoid valve after the second detection time after main gas control valve is opened; If when the probe of flame ion detecting electrode after closing kindling material combustion gas Controlling solenoid valve the first detection time in can't detect burning signal, by main for closedown gas control valve.
The deflagration phenomenon that ignition method of the present invention can effectively prevent combustion gas from producing at ignition point.Its Volume control is when opening point firearm power switch, and ignitor punctures air and produces electric spark.Kindling material combustion gas Controlling solenoid valve is opened and is confessed combustion gas by spark ignition to kindling material burner after a certain time.Ionization phenomena is produced after kindling material burner combustion, when fiery gas supply magnetic valve main after ionization detection electrode detection to kindling material ionization signal is opened automatically, combustion gas, by the flame ignition of kindling material, has effectively stopped the deflagration phenomenon produced when single-stage point cause of fire huge discharge combustion gas Controlling solenoid valve is opened.After main fire is lighted, kindling material closes burning automatically.If kindling material gas supply electromagnetic valve is opened rear combustion gas and do not lighted, kindling material magnetic valve automatic self-closing gas after certain hour effectively ensures the safety of fuel gas buring.
