Starting the burner is the first step in the normal operation of the boiler, and the burner is also one of the most important in the auxiliary equipment. In the event of a malfunction of the burner, it may cause a bad situation in which the entire boiler cannot be used. So how do you identify burner faults and eliminate them? FANGKUAI Boiler will answer your questions.
First, the ignition failure.
If the boiler burner fails to ignite three times in succession, it is judged to be an ignition failure. The troubleshooting is as follows:
1. If the pressure of natural gas cannot be maintained at 3-5kpa, it will not be ignited when pressure too high or too low.
2. If the damper of the burner is too large, it may easily lead to multiple ignitions failure.
3. When using the burner, if the ignition voltage is not ignited, or if the ignition electrode is too dirty or the position is wrong, an ignition failure will occur.
4. When the valve is normally ignited, the valve group will be opened in time, and the opening sound can be heard. If the valve is not opened, the flame will not be generated. Therefore, if the boiler valve group fails, it will not be ignited.
5. The ignition fault may also be caused by the ignition controller. If the ignition controller fails, it will cause normal ignition failure.
Second, the flameout failure.
The flameout fault refers to the sudden extinguishing of the fire when the burner is in normal operation. The operation of troubleshooting is as follows:
1. The instability of the gas source will cause the flame to fluctuate, resulting in fire extinguishing.
2. If the flame detector is failed during operation, the flame cannot be detected normally, and the flameout may occur.
3. the power supply is unstable or lack of equal circuit failure will also cause the flameout during operation.
FANGKUAI Boiler adopts the internationally renowned burner brand and is equipped with an automatic combustion system to achieve high-intelligence ignition. Only through the operation of the control system, various complex combustion mechanisms can be completed.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
