What causes the burner oil pump of the gas-fired boiler not to work?

22 Oct 2021

1. Fuel injection nozzle of combustion oil pump of gas boiler does not inject fuel.

Possible causes include blockage and leakage of oil supply pipeline. The solution is to clean, repair or replace;

 

2. The pressure of oil pump of gas boiler is low.

After long-term use and wear, the maximum pressure of the gas-fired oil pump of boiler will gradually decrease, resulting in poor atomization of oil injection and difficulty in ignition. After ignition, a large amount of smoke is emitted, and the flame is unstable, so it is useless to adjust the pressure of the oil pump. At this time, the oil pump needs to be replaced.

 

3. Oil is too viscous to flow, or oil contains more water.

Change oil or drain water.
