Coal – Types, Uses and Formation

On burning coal, coal ash is formed. This coal ash comprises several minerals like calcium and aluminium, which can be reused. About 40% of coal ash produced each year is effectively reused to fill coal mines that are abandoned. Sometimes, coal ash is used as the topmost layer on roads and foundations of high rise buildings.

Coal Combustion and Combustion Products

fresh coal on the bed surface is heated rapidly by the hot combustion gas and the radiation from the high-temperature flames and furnace walls. It is advantageous to the ignition of the coal. The burning coal then descends in turn through the reducing region and the oxidization region, becoming ash on the grate, and is finally removed. Figure 1.
