In order to fully burn the coal and improve the coal burning efficiency, the boiler is equipped with blower and induced draft fan with sufficient air volume, but it also brings two problems: on the one hand, the noise generated by the blower and induced draft fan during operation has seriously affected the health of the stoker and the living environment of the surrounding residents; On the other hand, although the use of blower and induced draft fan contributes to the full combustion of coal, heating a large amount of cold air also causes waste of resources
At present, coal-fired boilers are widely used in China, with a large number and a large annual coal consumption. The above problems are quite common
Therefore, the research on noise reduction and energy saving of boiler room is of practical significance
The heat needed by residents for heating in winter is mainly provided by boiler coal
