Coal Preparation Equipment

SKU: CHCPE00CENDuration: 60 Minutes

Coal preparation is an important aspect of coal handling. When coal leaves a plant's coal handling system, it generally is sent to one of two places. Depending on the design of the plant, the coal may go directly to a boiler furnace to be burned, or it may go through coal processing equipment, such as a pulverizer, before it is burned. In either case, coal usually has to be prepared during coal handling so that the pulverizing and burning will be more efficient. Coal preparation involves the use of special equipment that operators are often required to inspect, maintain, and troubleshoot. Operating coal preparation equipment properly can help prolong the life of the equipment and maximize the efficiency of the coal handling system.
