How does coal produce energy?

COal is used in boilers to make steam.Steam drives turbine \generators which produce electricity.


Huge boilers heat water using coal as fuel.Steam is produced in boilers at very high temperature and pressure..Steam drives Steam turbines which rotates generators to produce electric power.enter image source here

Coal is burned in boilers. Boilers make steam under high pressure and temperatures. This drives steam turbo generators which make electrical power.


Coal is a type of rock that forms when dead plant matter is compressed over a large period of time. This dead matter is buried and compressed under high temperatures as more and more soil and rock is layered on top of the dead matter. Eventually, the result is a sedimentary rock called coal that contains a large amount of carbon.

This rock is then usually pulverized into a powder and then it is burned in a coal power plant. When coal is burned, there are tubes of water in the boiler and this water is heated and boils (see image below). When the water boils, it transforms into steam. The steam then turns a turbine attached to a generator and electricity is produced.

Coal is also used in industry for other uses. For making steel, coal is used in blast furnaces to make heat to melt steel. Coal is heated with steam and the gas that is produced is distributed as demotic/industrial gas in some old cities. Old steam loco motives coal was used a fuel to run railway coaches..
