Discussion on Vibration Reduction and Noise Reduction of Cen-trifugal Fans for Boilers
In order to solve the problem of vibration and noise of centrifugal fans used in boilers,it is necessary to identify the sources and propagation pathways of noise from centrifugal fans.By comparing the noise data of centrifugal fans in a certain industrial plant at different time periods and loads,it was found that the conventional noise level of fans is directly related to the fan load.The larger the load,the greater the noise.By analyzing the implementation cases of vibration reduction and noise reduction in boiler fan buildings,it was found that the abnormal noise level of the fan is mainly related to the fluid flow state inside the air duct.At the same time,drawing on relevant cases of vibration reduction and noise reduction in fan rooms,this paper discusses the fluid model of fan ducts,damping materials for wind ducts,and fan vibration reduction and noise reduc-tion accessories respectively,in order to reduce fan noise pollution and improve the quality of the working environment for rel-evant personnel.
