Modeling and Control of Coal Mill

Coal mill is an important component of the thermal power pla nt. It is used to grind and dry the moisturized raw coal and transport the pulverized coal ± air mixture to the boiler. Poor dynamic performance of coal mill will lead to decrease in the overall efficiency of the power plant, slow load take up rate and fr equent shut down.
