Boiler
Thermal power is supplied by a fuel to a boiler. [1] Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle. The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam.

Electric Resistance Heating | Department of Energy
Electric resistance heating is energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity. Because of electricity generation and transmission losses, electric heat is often ...
Our Energy Sources, Coal — The National Academies
In addition, competing energy sources for electricity generation could reduce the demand for coal. Future increases in the supply will probably come from western states because of the low sulfur content of the resource in that region, which now provides about 57% of the nation's coal. Wyoming alone typically accounts for about 42% of all ...

The Types of Coal: Composition, Usage, and Energy Value
Coal releases thermal energy or heat when it is burned, along with carbon and ash. Ash is made up of minerals such as iron, aluminum, limestone, clay, and silica, as well as trace elements such as arsenic and chromium. The stored energy potential within coal is described as the "calorific value," "heating value," or "heat content.".

Coal & electricity
Steam coal, also known as thermal coal, is used in power stations to generate electricity. First coal is milled to a fine powder, which increases the surface area and allows it to burn more quickly. In pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high temperature.
