What should I do if the burner of the fuel boiler fails to ignite?
The problem of non ignition of fuel boiler burners has puzzled many enterprises and caused headaches for many distributors. Actually, solving this problem is not difficult. The difficulty lies in how to identify the problem and find a solution. These tedious tasks have surely stumped many people. Now let’s learn together what to do if the burner of a fuel boiler malfunctions and fails to ignite?
After starting, the front blowing is normal, but it cannot ignite. Reason: 1. Insufficient ignition gas volume; 2. The solenoid valve is not working (main valve, ignition valve); 3. The solenoid valve is burnt out; 4. Unstable air pressure; 5. The air volume is too high.
Exclusion measures: 1. Check the circuit and repair it; 2. Replace with a new one; 3. Adjust the air pressure to the specified value; 4. Reduce air distribution and decrease the opening of the air door
Unable to ignite, normal air pressure, electrical failure. Reason: 1. Ignition transformer burned out; 2. High voltage lines are damaged or detached; 3. The gap is too large or too small, and the relative size of the ignition rod position; 4. Electrode rupture or short circuit with ground; 5. The spacing is not appropriate.
Exclusion measures: 1. Replace with a new one; 2. Reinstall or replace; 3. Readjust; 4. Reinstall or replace; 5. Readjust.
Reasons for stalling after 5 seconds of ignition: 1. Insufficient air pressure, excessive pressure drop, and low gas supply flow rate; 2. The air volume is too low, the combustion is not sufficient, and the smoke color is thick.
3. The air volume is too high, resulting in white air.
Exclusion measures: 1. Adjust the air pressure again and clean the filter screen; 2. Readjust; 3. Readjust.
Reasons for emitting white smoke: 1. Too low air volume; 2. The air humidity is too high; 3. The exhaust temperature is relatively low.
Exclusion measures: 1. Reduce the air damper; 2. Reduce the air volume appropriately and increase the inlet air temperature; 3. Take measures to increase the exhaust temperature.
Reasons for chimney dripping: 1. Low ambient temperature; 2. There are many processes of small fire combustion; 3. Gas has a high hydrogen content and generates water with a large amount of peroxide; 4. The chimney is relatively long.
Exclusion measures: 1. Reduce the air distribution volume; 2. Reduce chimney height; 3. Increase furnace temperature; 4. When the exhaust temperature is low, the air door is stopped under control and the position switch signal of the air door is not fed back to the program signal. Check if the air door wiring is loose or if the switch is malfunctioning.
