In a coal based power plant coal is transported from coal mines to the power plant by railway in wagons or in a merrygoround system. Coal is unloaded from the wagons to a moving underground conveyor belt. This coal from the mines is of no uniform size. So it is taken to the Crusher house and crushed to a size of 20mm. From the crusher house the coal is either stored in dead storage ...

plants. Lignite combustion has advanced from small stokers to large pulverized coal (PC) and cyclonefired units (greater than 500 megawatt). The major advantages of firing lignite are that it is relatively abundant (in the North Dakota and Texas regions), relatively low in cost since it is surface mined, and low in sulfur content which can reduce the need for postcombustion sulfur emission ...
