Reasons for the unsuccessful ignition of the boiler burner

1. check whether the burner For Boiler is locked, that is, whether the reset button of the burner program controller lights up with a red light (also called an alarm light).

2.Input; the power supply is normal, the alarm light is on, press the reset button for 1 second to
release,The flame detection is not very ideal. 
3. Is the air supply pressure stable and whether it meets the combustion requirements.
4. The flow is not enough, and the fuel or gas cannot keep up.
5. If there is a high and low pressure switch, consider the pressure problem. Whether the self-test procedure fails .
6. Is the ignition transformer normal ? It is necessary to check one by one on the spot. The burner does not operate and the red light goes out but soon turns red again. This is the fault of the flame detection system of the burner. Interference signals are mostly caused by light leakage from the combustion chamber, damage to the photoelectric eye, short circuit of the photoelectric eye signal line, etc. Press the reset button for 1 second to release the burner fan action, but the electric spark will not appear, and then the alarm will be locked. Check whether the oil circuit switches are all turned on and there is oil in the fuel tank, whether the oil circuit filter is blocked, the oil pipe is leaking, the oil pump is damaged or worn, the coupling is damaged and slipped, the solenoid valve fails to open, the fuel nozzle is blocked, etc.;
Fuel injection Can also spew flames, but then locks. This is the programmer not sensing the flame. It may be caused by the damage of the photoelectric eye or the dirt on the sightseeing surface, the open circuit of the signal line of the photoelectric eye, the damage of the program controller, and the unstable flame .
