Coal washing Coal that comes from a mine is a complex mixture of materials with a large variety of physical properties. In addition to the coal itself, pieces of rock, sand, and various minerals are contained in the mixture. Thus, before coal can be sold to consumers, it must be cleaned.
washing, the coal's heating value can be improved dramatically . This means that less coal must be burned to produce a comparable amount of electricity . Thus, power plants that use higher quality coal will have an economic and performance advantage over those that use lesser quality coal . (2) Improve Plant Operations
A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam.
