Induced draft fans have important applications in industrial boiler systems, which can increase gas pressure and discharge gas. Once the induced fan has abnormal noise and other failures, it is very likely to endanger the normal operation of the boiler. We need to analyze the abnormal vibration machine of the induced draft fan and take effective measures to cope with it to provide guarantee for the normal operation of industrial boilers.
First of all, it is necessary to analyze the cause of the induced fan vibration. The causes of induced fan vibration mainly include vibration of motor, induced fan bearing box, coupling, fan casing, impeller, etc.
When the induced draft fan vibrates, it will cause injury to people and equipment.
1. Harm to people. When working in a vibrating environment, human vision will be disturbed and it is difficult to concentrate, which may lead to quality accidents and even safety accidents. Vibration can interfere with the daily life of people around, such as sleep, rest, reading, and damage people's health.2. Harm to the boiler room. Depending on the vibration intensity and frequency of the induced draft fan, it will destroy the building structure of the boiler room.
3. Harm to industrial boilers. The vibration of the induced draft fan will harm the normal operation of precision instruments, affect the accuracy and reading speed of the scale reading, or even fail to read at all.
4. Harm of noise to the environment. The vibration of the induced draft fan will directly radiate noise into the space, and it will propagate in the soil. During the propagation process, it will also agitate the vibration of the building foundation, walls, beams, ceilings, doors, windows and pipes. Radiate the noise again.
Therefore, we have to find out the main cause of the induced draft fan vibration of industrial boilers, and start to deal with the vibration fault immediately.






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:
