A Coal-Fired Thermoelectric Power Plant - USGS

A large thermoelectric plant like this burns a lot of coal—in this case, about 11 million tons per year. Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam.

What is clean coal technology? | HowStuffWorks

Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers. A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel. But most coal -- 92 percent of the U.S. supply -- goes into power production [source: Energy Information Administration]. Electric companies and businesses with power plants burn coal to make the steam that turns turbines and generates electricity.

More U.S. coal-fired power plants are decommissioning as

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.

Fossil fuel power station - Wikipedia

Power plants remove particulate from the flue gas with the use of a bag house or electrostatic precipitator. Several newer plants that burn coal use a different process, Integrated Gasification Combined Cycle in which synthesis gas is made out of a reaction between coal and water. The synthesis gas is processed to remove most pollutants and

How a Coal Plant Works - TVA.com

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.

Coal based power plant - SlideShare

6/16/2014 · A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. [Rankine cycle] Coal is used as a fuel to heat water in a coal based thermal power plant.

Coal | Uses, Types, Pollution, & Facts | Britannica

Four general methods are used for liquefaction: (1) pyrolysis and hydrocarbonization (coal is heated in the absence of air or in a stream of hydrogen), (2) solvent extraction (coal hydrocarbons are selectively dissolved and hydrogen is added to produce the desired liquids), (3) catalytic liquefaction (hydrogenation takes place in the presence of a catalyst—for example, zinc chloride), and (4) indirect liquefaction (carbon monoxide and hydrogen are combined in the presence of a catalyst).
