Power Plants and Types of Power Plant

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal. Vast deposits of coal originates in former

Power Plants in the United States – Electric Choice

Coal is one of the most commonly used fossil fuels used to generate electricity in a fossil fuel power station. These plants can use either a steam or combustion turbine. The coal is burned in a boiler at high temperatures. The steam produced moves a turbine, which then moves the generator to produce energy.

How a Coal Plant Works. 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.

Power Plant

A power plant is an industrial facility used to generate electric power with the help of one or more generators which converts different energy sources into electric power. Electricity is a secondary energy source, which means that electricity is obtained from the conversion of other primary sources of energy, such as coal, natural gas, nuclear, solar, or wind energy.
