Pollution control in coal power plants is critical. In this blog, we explore the different technologies used and the differences between them. Pollution Control. Thermal Power Plants produce electricity by first creating heat, and the U.S.A. still produces most of our energy by burning fossil fuels (coal, natural gas, or oil) to create this heat.

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, low-carbon peat, to coal, an energy- and carbon-dense black or brownish-black sedimentary rock.

The main raw material used for power generation is coal. Coal is a more abundant fossil fuel than either crude oil or natural gas, and coal deposits are distributed throughout the world. Economic development over many centuries was supported by the use of coal.
