When the second solenoid valve is slammed, there is gas output. To supply the combustion gas; once the small fire assembly burner 03 does not emit the flame, the cluster thermocouple is not heated, there is no voltage output, so that the second solenoid valve is closed, and there is no gas supply to the burner, thus the burner Stop running. Therefore, the cluster thermocouple must always be in the long flame at high temperature, so the bundle thermocouple is easily burned;
  • thermocouple 01 As in the above-mentioned long open flame ignition device, in order for the small fire assembly burner to continuously emit a long flame, the thermocouple 01 must always generate a current of >80!11, and the thermocouple 01 must be placed all the way. In the Changming flame, the same as above, the thermocouple is exposed to high temperature for a long time, causing fouling of the outer shell of the thermocouple, resulting in a decrease in thermal conductivity and sensitivity, and even failure of the thermocouple.
