In a coal-fired steam station much like a nuclear station water is turned into steam, which in turn drives turbine generators to produce electricity. Here’s how the process works. 1. Heat is created Before the coal is burned, it is pulverized to the fineness of talcum powder.
Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

Why energy efficiency? Much effort is currently being focused on reducing greenhouse gas emissions from coal-fired power generation. However, it is just as important to reduce the amount of carbon dioxide (CO 2) that ends up in the waste flue gas that comes out of the flue stack of a power station.This is done by improving the efficiency of the coal combustion process.
Coal has the largest share of utility power generation in the United States, accounting for approximately 56% of all utility-produced electricity (U.S. DOE, 1998). Therefore, understanding the environmental implications of producing electricity from coal is an important component of any plan to reduce total emissions and resource consumption.
During a coal-fired plant’s decommissioning process, the electric-generating equipment—such as precipitators, boilers, turbines, and generators—are shut down and operating permits are terminated.Unused coal and materials associated with both the generation process and the buildings and structures are removed. The electric-generating equipment may be used at other plants or sold

Most of U.S. electricity generation is from electric power plants that use a turbine or similar machine to drive electricity generators. A turbine converts the potential and kinetic energy of a moving fluid (liquid or gas) to mechanical energy. In a turbine generator, a moving fluid—such as water, steam, combustion gases, or air—pushes a series of blades mounted on a shaft, which rotates
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce electricity.Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator.The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.

Most people know coal as a fossil fuel which is used to produce around 40 percent of the world’s electricity. 1 It’s a flammable black or brown sedimentary rock, and is made mostly of organic carbon. However, there are actually two main types of coal: ‘thermal’ coal, which is mostly used for power generation, and ‘metallurgical’ coal, which is mostly used for steel production.
