Read further to know more. Coal Gasification is the process of converting coal into synthetic gas (syngas) which is a mixture of hydrogen (H2), Carbon Monoxide (CO), and Carbon dioxide (CO2). It is an in situ process in which oxygen is injected into the seam along with water and ignited at a high temperature, which causes the coal to partially ...

sufficient coal reserves available to keep the power station in operation should the mine experience production problems. Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas. The pulverised coal is transported to the boiler furnace with air where it ...

In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.
