Description
Technical field:
The invention belongs to the firing technique field in the gas furnace, what be specifically related to is a kind of igniter of burner.
Background technology:
Be widely used in the gas burner safety control circuit at present and mostly be single-stage flame combustion control mode.This control mode is adapted to the small-power burning heating equipment and uses, but to high-power firing equipment since the ignition point combustion gas in a large number discharging the combustion gas deflagration phenomenon can appear, the security when having a strong impact on fuel gas buring and lighting.
Summary of the invention:
The purpose of this invention is to provide a kind of combustion gas deflagration phenomenon that can overcome high-power burning heating equipment burner igniter and use the ignition method of this kind 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 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 the top, described air inlet pipeline is provided with kindling material combustion gas control magnetic valve, described kindling material combustion gas control magnetic valve is connected on the control circuit, described control circuit also is provided with and is connected with a main fiery gas supply magnetic valve, and main fiery gas supply magnetic valve is used to control the main combustible pipe road of burner.
Described igniter is the crosspointer igniter.
The probe of described flame ion detecting electrode crosses the main burner top from the outlet of kindling material burner.
The present invention also provides a kind of ignition method that uses above-mentioned igniter: described method comprises step:
1), the power connection of igniter, ignitor produces electric spark;
2), connect back first blanking time at interval at igniter, kindling material combustion gas control magnetic valve is opened, and electric spark is lighted the kindling material burner; If the probe of flame ion detecting electrode after kindling material combustion gas control magnetic valve is opened through first detection time in detect less than the burning signal, will close kindling material combustion gas control magnetic valve.
3), when the probe in detecting of flame ion detecting electrode after light the signal that the kindling material burner lighted, open main gas control valve, main burner is sent in combustion gas, the flare of kindling material burner is lighted main burner, and closes kindling material combustion gas control magnetic valve after second detection time after main gas control valve is opened; If after the probe of flame ion detecting electrode is cutting out kindling material combustion gas control magnetic valve first detection time in detection less than the signal that burns, will close main gas control valve.
Ignition method of the present invention can effectively prevent the deflagration phenomenon that combustion gas produces at ignition point.Its control characteristics are when opening point firearm power switch, and ignitor punctures air and produces electric spark.Kindling material combustion gas control magnetic valve is opened kind of the burner that warms oneself in front of a fire and is confessed combustion gas and lighted by electric spark behind certain hour.Produce ionization phenomena after the kindling material burner combustion, when ionization detection electrode detection main fiery gas supply magnetic valve behind the kindling material ionization signal is opened automatically, combustion gas is by the flame ignition of kindling material, effectively stopped when the big discharge capacity combustion gas control of single-stage point cause of fire magnetic valve is opened and the deflagration phenomenon that produces.Kindling material is closed burning automatically after main fire is lighted.If the kindling material gas supply electromagnetic valve is opened the back combustion gas and do not lighted, kindling material magnetic valve automatic self-closing gas behind the certain hour effectively guarantees the safety of fuel gas buring.
