Potential Causes of Boiler Shutdown
Fuel issues: Insufficient or interrupted fuel supply, such as low gas pressure or fuel pump failure.
- Ignition system failure: Dirty ignition electrodes, faulty ignition transformer, тощо.
- Poor combustion: Improper air–fuel ratio, burner blockage, тощо.
- Safety protection activation: Such as low water level protection, overpressure protection, тощо.
- Electrical failure: Power interruption, controller malfunction, тощо.
Boiler Restart Procedure
Identify the cause: First determine the reason for the flameout and eliminate the fault.
Reset safety devices: If the shutdown was caused by a safety protection device, reset the relevant device.
- Ventilation: Ensure the boiler room is well ventilated to remove any accumulated combustible gases.
- Ignition: Follow the boiler operation manual to relight the boiler. Зазвичай, this involves opening the gas valve and initiating the ignition sequence.
Monitor operation: After successful ignition, closely monitor the boiler’s operating condition to ensure all parameters are within the normal range.
