2015 11 1 Most of the thermal power plants in the world are coal fired. They contribute to major part of the world total electric supply. Coal fired plants are known to have low load take up rate and sometimes face complete shutdown. This is basically due to the poor dynamic response of the coal mills. This paper focuses on the flow control of pulverized fuel pf flow of the coal mill.
