Electricity Generation from coal-fired, natural gas, and ...

Coal fired power plants: The first step in producing electricity from coal requires the coal to be broken up into powder. This makes the coal more easy to burn and use as fuel. After it is made into powder it is blown into the boiler where it is then converted from chemical energy into heat energy.

Coal - Wikipedia

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.

Pulverized coal-fired boiler - Wikipedia

A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Coal power technologies - SourceWatch

In the first step, coal is converted into synthetic gas or syngas. In the second step, the gas is used to power a steam turbine, with waste heat from the turbine being recovered to provide additional power (hence the term "combined cycle"). Such plants are considered "integrated" because the two steps occur at the same facility in tandem.
