Coalfired power plants have been identified as one of the major sources of air pollutants in the power sector. Most coalfired power stations have large openair coal stockpiles, which lead to a considerable amount of fugitive dust. The construction of an indoor coal storage is known to control coal dust; however, it requires significant upfront capital. Certain power utilities, including ...

A coalfired power station burns coal to generate electricity. There are many such power plants around the world, including in Israel. Their operating principle is simple: Burning coal heats water in a closed system. The water evaporates and becomes steam. The steam is used to drive a turbine, driving the magnet array that creates an electric field. In fact, this is the transformation of the ...

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.
