A certain amount of electricity can be generated by burning a set amount of coal in a power plant. But, the efficiency of the power plant and the type of coal being burned also affect how much coal is required to generate the desired electricity. In the United States, a typical coalired power plant operating at efficiency requires about pounds of coal to generate megawattour (MWh) of electricity. If the same power plant were operated at efficiency, it would only require pounds of coal per MWh.

What Are The Different Methods Of Generating Electricity From Coal?

Assuming you would like a general overview: The most common method of generating electricity from coal is pulverized coalired generation. In this process, coal is ground up into a powder and then combusted in a boiler to produce heat, which in turn produces steam. The steam spins a turbine, which turns a generator and produces electricity.

Another method is circulating fluidized bed combustion, which involves blowing air through a bed of pulverized coal to create a hot gas. That gas then turns a turbine connected to a generator. A less common method is integrated gasification combined cycle, which first creates a synthetic gas from coal and then uses that gas to power a gas turbine connected to a generator.

Finally, there is Enhanced Coal Bed Methane Recovery, which involves drilling into a coal seam and then using a pump to force methane gas out of the coal and into a pipe. That gas can then be used in a gas turbine to generate electricity.
