Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...

The purpose of the coal stockyard is to ensure that there is sufficient coal reserves available to keep the power station in operation should the mine experience production problems. Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas.

Coal is the most available fuel, has a rather stable price and as a result is the most costeffective fossilfired technology. Nowadays, crude oil or heavy fuel oil have become quite unusual as fuels for electricity generation purposes. Sulzer provides maintenance and service for all rotating equipment to improve efficiency and reliability.

Coal plays a dual role in the Kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temp. But main role of coal is to supply carbon in the reduction process. Dolomite is used as sulphur scavenger which finally comes out with the char. Char contains ash of coal and other impurities of iron ore.
