The Coal Power Plant or Steam Power Plant has four major circuits by which the layout can be studied in detail. These are. 1. Coal and ash Circuit: This circuit consists of coal delivery, preparation of coal, handling of coal to the boiler furnace, ash handling and ash storage. The coal which is received from the mines are stored in coal storage.

A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes.
