Common failure causes and treatment methods of low-nitrogen burners! Low-nitrogen burners are important equipment installed on industrial oil-fired boilers and gas-fired boilers to control pollutant emissions, but many failures will inevitably occur during use, so all What is the cause? What are the treatment methods?

1. The burner motor does not turn:

Reason: There is no voltage, the thermal relay operates, the fuse is damaged, the zero line is interrupted, the motor fails, the control circuit is interrupted, the gas transmission is interrupted, the ball valve is closed, and the controller fails;

Solution: connect the circuit, reset, replace, repair, replace, find the disconnection point, connect or disconnect the regulator or controller, and open the ball valve for replacement. the

2. The low-nitrogen burner motor runs, but a fault occurs during the pre-purge for about 10 seconds:

Reason: The setting value of the air pressure switch is not correct. The air pressure switch fails. The air pressure switch pipe is blocked. The blower is polluted and the burner motor is reversed;

Solution: reset, replace, clean and clean the motor. the

3. The burner motor runs, but fails during pre-purge for about 20 seconds:

Reason: The solenoid valve is not sealed, the solenoid valve is polluted and the solenoid valve is damaged;

Treatment method: clean and replace. the

4. The motor of the low-nitrogen burner is running, and the voltage has been applied to the input terminal of the transformer:

Reason: the distance between the ignition electrodes is too large, the ignition electrode or the circuit grounding ignition transformer is out of order;

Treatment method: re-adjust to exclude grounding, replace damaged electrodes or replace cables. the

5. The motor runs normally and the ignition is normal, but it fails later:

Reason: The solenoid valve is not open: The solenoid valve coil is damaged. The solenoid valve is not powered;

Solution: replace the solenoid valve and check the circuit. the

6. The motor runs normally, the ignition is normal, but it stops later, and there is no fault display:

Reason: The gas filter is clogged;

Treatment method: turn on the electromagnetic. the

the

The above are the common fault causes and treatment methods of low-nitrogen burners. Low-nitrogen burners are important equipment installed on industrial oil-fired boilers and gas-fired boilers to control pollutant emissions. By adjusting the combustion air and combustion head, the fuel can be stably ignited Combustion and complete combustion, improve combustion efficiency and reduce nitrogen oxide content, combustion parameters can be obtained to meet emission standards.
