A Simulation Model to Predict Coal-Fired Power Plant
It uses coal energy to convert it into mechanical energy through the expansion of steam in steam turbines. Coal received from collieries in the rail wagons is routed by belt conveyors. After crushing the coal in coal mills, it is then pushed to the boiler furnace (1), which is comprised of water tube walls all around through which water circulates.
