The average compositions for dried coal are shown in Fig. 1 Based on the coal composition, the net heat value has been found to be 30,600kJ/kg-coal. The stream data obtained from the plant is used to perform a mass balance over the system. It is usually more convenient to define mass/energy data per kg clinker produced per unit time.

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

(iii) Grinding of Clinker. As the lump-shaped clinker comes out from the kiln, it is extremely hot. It is, therefore, passed through air-cooling rotary cylinders. After that, it is mixed with 3-4 percent of gypsum and ground to a very fine powder as discussed above in the DRY PROCESS of cement manufacturing.

Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall. Organic compounds are also often added as grinding aids to avoid powder agglomeration.
