Research on fault diagnosis of coal mill system based
Coal mill is an important auxiliary equipment of the coal-fired power plant, and its status is directly related to the security and stability operation of the unit. The coal feed flow into the boiler cannot be guaranteed if faults occur in the coal mill. In this case, the energy output from the boiler cannot match the energy demand of the turbine.Web
