Modeling and outlet temperature control of coal mill using performance analysis of coal mill

Abstract Coal mills are used to grind and dry the raw coal containing moisture and to transport the pulverized coal air mixture to the boiler Poor dynamic performance of coal mill causes difficulties in maintaining the frequency boiler pressure and temperature of the plantAbstract Coal mill is an essential component of a coal fired power plant that affects the performance reliability and downtime of the plant The availability of the milling system is influenced by poor controls and faults occurring inside the mills
