A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
Many power plants produce CO2 emissions. The electric power sector is a large source of CO2 emissions. Electric power sector power plants that burned fossil fuels or materials made from fossil fuels, and some geothermal power plants, were the source of about 33% of total energyrelated CO2 emissions in 2018.

Switching from coal to wind power will help decrease the amount of sulfur oxides emitted into the atmosphere. This will reduce acid deposition and the chances of acid rain occurring in a given area. Another environmental benefit is that there will be reduced acid mine drainage from coal mines, which will create a pH change in aquatic habitats.
A coalfired power station or coal power plant is a thermal power station which burns coal to generate power stations generate over a third of the world''s electricity but cause hundreds of thousands of early deaths each year, mainly from air pollution..

The heart of a coalfired power plant is a boiler, in which coal is burned by combustion to turn water into steam. The following equation shows what burning coal looks like chemically: C + O 2> CO 2. Coal isn''t made of pure carbon, but of carbon bound to many other elements.
Coal occurs after living materials like plants and animals collect in a swampy region decay and degrade by decomposition of microorganism resulting in solid products, which can produce heat. On the other hand, charcoal occurs after plats, especially woods and plant trumps are exposed to heat and a limited supply of oxygen.

Of the total retired capacity, coal power plants and natural gas steam turbines accounted for the highest percentages, 47% and 26%, respectively. Most of the planned retirements through 2020 will also be coal plants and natural gas steam turbines, based on information reported to EIA. Various factors influence the decision to retire a power plant.
Jan 29, 2020· The stored energy potential within coal is described as the "calorific value," "heating value," or "heat content." It''s measured in British thermal units (Btu) or millijoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately gallons—a pound of water—by 1 degree Fahrenheit at sea level.
In burning coal for energy, the many negative externalities of coal (such as: contributing significantly to climate change, damage to the public health, damage to plant and animal ecosystems, and other damage to the environment from coal pollution) must be considered; external costs which add dramatically to the economic and social cost of coal.
