Thermal power plant development started in 1866 when Werner von Siemens built the first dynamo for power generation. Years later in 1882, Thomas Edison developed the first central power station in New York [37]. In the first steam generators, the generated steam to drive the DC dynamos is either lowpressure saturated or slightly superheated.

The steam for process purposes is extracted from a certain section of turbine and the remaining steam is allowed to expand in the turbine. Alternatively the exhaust steam may be used for process purposes. Thermal stations can be private industrial plants and central station.

2. Process description of a coalfired power plant. A coalfired power plant burns coal to produce electricity. In a typical coalfired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

Brown and black coal are mostly used as a source of fuel for power stations. Burning the coal produces heat which is used to make steam, so the the coal is sometimes called thermal or steam coal. The steam spins turbines to generate electricity. In Australia in 2017 coal was used to produce about 60% of the nation's electricity requirements.
