Coal fired power plant (Principle, Diagram andThe coal power plant diagram shows the components of the plant and the different stages of transforming the chemical energy (coal) into electrical energy as We started with the boiler or the steam generation system as we supply the coal from coal bunkers via coal conveyors to be crushed into coal mills.mill coal feeders on linecoal mill and feeder.Feed belts (distributors) then transport the coal to the coal mill, where it is ground into dust and blown into the boiler. In order to ensure the fuel supply to the boiler in periods of full load, and especially low load, three redundant measuring systems are employed per feed belt.
Nov 17, 2012 2.Coal pulverizer mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner.Than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal air mixture in the system becomes leaner and the coal dust will be ground to a uniformly fine size and dried to a greater extent.
