In the operation of a coal fired electric power plant, coal is fed to a pulverizer mill where it is finely ground for mixture with the primary air flow and transported to the burners. In many cases, the inlet hot and cold air flow mix is varied by damper positioning to hold a desired mill exit temperature for the primary air and coal mixture.The mode of operation is same for all mills. Operation of all the pyrite hopper pneumatic conveying system is independent of each other. The Vessels will be in operation sequentially.
