In the process of using gas boilers, there are often cases where the fire cannot be ignited. Of course, the failure to ignite is also a common fault. The most direct impact is that the boiler cannot work normally and affects production. So today, let's understand why the boiler burner cannot start?
1. The boiler emergency stop switch is misoperated, and the burner does not ignite (the boiler does not run). Treatment method: At this time, all functions are generally unusable and can be monitored by yourself.
2. Solenoid valve failure: If only the ignition sound is heard when the gas boiler is ignited, and there is no "click" magnetic suction sound of the solenoid valve, it may be that the solenoid valve is damaged or aged. The solenoid valve is aged and will be out of control. It can be attracted at the beginning of the ignition and ignite, but it will close and go out again; before confirming whether the solenoid valve is good or bad, it is necessary to confirm whether the igniter control circuit is normal. If there is a problem, the solenoid valve cannot be controlled to attract. The burner is not reasonable in debugging gas and controlling air distribution, and the burner automatically goes out after ignition. Treatment method: The gas and air debugging ratio is incorrect, the air intake is too large, and the fire is automatically extinguished after ignition
3. Natural gas leaks, and the burner does not ignite. Treatment method: Generally, the burner has its own leak detection device and can monitor it by itself.
4. The gas inlet pressure is too low or too high, and the burner does not ignite. Treatment method: Check the burner inlet pressure gauge to see if the pressure is the ignition pressure of the boiler
5. The smoke pipe cannot be exhausted normally. The gas boiler smoke pipe is blocked, and the smoke pipe blockage is cleared. The smoke pipe is too long and not installed correctly. The exhaust temperature is too high, the boiler automatically interlocks and protects, and the burner does not ignite. Treatment method: Check the boiler exhaust temperature to see if it is higher than the boiler's shutdown smoke temperature
6. Water-gas linkage installation failure: The tympanic membrane in the water-gas linkage valve of the gas boiler is aged or damaged and cannot push the micro switch; the micro switch is broken.
7. Ignitor failure: If one of the pulse igniter and the controller fails, the gas boiler cannot start. Set the boiler ignition pressure too high or too low, and it is not within the ignition range. Treatment method: Check the boiler pressure and see if the pressure is within the ignition pressure range of the burner. It can be operated in the control cabinet.
8. Water level problem: The filter screen at the water inlet of the gas boiler is blocked, causing water to not flow normally. The boiler water level is too low, lower than the ultra-low water level of the boiler, the boiler automatically interlocks, and the burner does not ignite. Treatment method: Check the boiler water level to see if it is lower than the ultra-low water level of the boiler, and clean the filter plug.
Many faults will have corresponding solutions. Finding the right method for targeted solutions can quickly solve equipment failures and other situations. However, it is best not to operate the product recklessly without understanding it, which will affect the performance of other aspects of the equipment. In the worst case, contact the technicians of the equipment manufacturer for professional guidance.
