When using a gas boiler, it often fails to ignite. This is a common malfunction, directly impacting the boiler's normal operation and impacting production. So, let's explore the reasons why a boiler burner fails to start.
1. The boiler's emergency stop switch is incorrectly operated, causing the burner to fail to ignite (the boiler won't operate). Solution: Generally, all functions will be unavailable at this point, but you can monitor the situation yourself.
2. Solenoid Valve Fault: If only the ignition sound is heard during ignition without the solenoid valve's magnetic engagement sound, the solenoid valve may be damaged or aged. Aging solenoid valves can become uncontrolled, closing briefly at the start of ignition and igniting, but then closing and extinguishing. Before verifying the solenoid valve's condition, ensure that the igniter control circuit is functioning properly. If a malfunction occurs, the solenoid valve will not engage. Improper gas and air distribution during burner commissioning may be causing the burner to automatically shut down after ignition. Solution: The gas-to-air ratio is incorrect, the air intake is too high, and the fire automatically extinguishes after ignition.
3. Natural gas leak, the burner fails to ignite. Solution: Most burners have built-in leak detection devices that can monitor the burner's operation.
4. The gas inlet pressure is too low or too high, causing the burner to fail to ignite. Solution: Check the burner inlet pressure gauge to see if the pressure is within the boiler's ignition pressure.
5. The flue pipe is not venting properly. The gas boiler flue pipe is blocked. Remove the blockage. The flue pipe is too long or improperly installed. The exhaust gas temperature is too high, causing the boiler to automatically lock out, causing the burner to fail to ignite. Solution: Check the boiler exhaust gas temperature to see if it exceeds the boiler's shutdown temperature.
6. Water-gas linkage installation error: The internal diaphragm of the gas boiler's water-gas linkage valve is aged or damaged, preventing it from pushing the microswitch; the microswitch is faulty.
7. Ignitor problem: If either the pulse igniter or the controller fails, the gas boiler will fail to start. The boiler's ignition pressure is set too high or too low, outside the ignition range. Solution: Check the boiler pressure to see if it's within the burner's ignition pressure range. This can be done from the control cabinet.
8. Water Level Problem: The filter at the gas boiler's water inlet is clogged, preventing water from flowing properly. The boiler water level is too low, below the minimum water level, causing the boiler to automatically lock out and the burner to ignite. Solution: Check the boiler water level to see if it's below the minimum water level and clean the filter plug.
Many faults have corresponding solutions. Finding the right solution can quickly resolve equipment problems. However, be careful not to operate the product recklessly without understanding the product's function, as this can affect other aspects of the equipment's performance. In the worst-case scenario, contact the manufacturer's technician for professional guidance.
