The effect of fly ash on the environment can vary based on the thermal power plant where it is produced, as well as the proportion of fly ash to bottom ash in the waste product. This is due to the different chemical makeup of the coal based on the geology of the area the coal is found and the burning process of the coal in the power plant.

A. THERMAL POWER PLANT COMPONENT AND ITS AUXILIARIES 1) FUEL PREPARATION SYSTEM: In coalfired power stations, the raw feed coal from the coal storage area is first crushed into small pieces and then conveyed to the coal feed hoppers at the boilers. The coal is next pulverized into a very fine powder, so that coal will undergo
