Electrical Working Principle of Controllable Infrared Catalytic Burner

一、 Working Purpose

When the oven temperature reach setting required temperature, the infrared catalytic burner stop working; While the oven temperature under setting required temperature, the infrared catalytic burner start working again.

二、Composition of Electrical System

1.Electronic Control System

Input Power(AC220 V or AC110 V)+ Thermocouple+ Electric Cabinet(Temperature Controller +Power switch+ Ignite switch+ working indicator light+ Alarm+ Air switch+ Relay) + Pluse ignitor + Solenoid valve+ Ignition neddle

2.Gas Control System

Gas + Barometer+ Pressure Regulating Valve+ Solenoid Valve+ Infrared Catalytic Burner

三、Working Principle

Open the gas valve, adjust the combustible gas pressure to 3500~5000pa by pressure regulating valve. Open the main power switch of electric cabinet and set the oven inside heating temperature on temperature controller, then open the burner ignition switch, the solenoid vale supply gas for the infrared catalytic burner when the  pluse ignitor is electrified. At the same time, the pluse ignitor outputs high voltage to  ignition needle, and ignition needle produces electric arc so as to ignite the combustible gas in infrared catalytic burner.

After the infrared catalytic burner work normally, pulse ignition stop outputting high voltage, and ignition needle stop producing electric arc.

When the thermocouple reacts the oven temperature lower than setting temperature of controller, the solenoid valve will restart to supply gas after the pluse ignitor gets signal from temperature controller. Meanwhile, the pluse ignitor outputs high voltage to igniton neddle, and ignition needle produces electric arc so as to ignite the combustible gas, the infrared catalytic burner gets work.

四、Flameout Protection

When the electric arc produced by ignition needle doesn’t ignite the flammable gas in infrared catalytic burner, pluse ignitor will stop outputing high voltage and shutting solenoid valve to supply gas. It will prevent the gas from leakage and sure security. 

If need to start again, you must open the ignition switch and pulse ignition of electric cabinet to get electricity, to reboot your ignition system normal working.
