Steam Power Stations - Arrangement and Working

(i) Boiler. The heat of combustion of coal in the boiler is utilized to convert water into steam at high temperature and pressure. The flue gases from the boiler make their journey through superheater economizer air pre-heater and are finally exhausted to atmosphere through the chimney. (ii) Superheater . The steam produced in the boiler is wet and is passed through a superheater where it is ...

How a Coal Plant Works - TVA.com

How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced under tremendous pressure flows into a turbine which spins a generator to create electricity. The steam is then cooled condensed back into water and returned to the boiler to start the process over.

Other changes must be made too. When coal burns in oxygen the flame temperature can reach 2500 oC far higher than current materials can stand. To overcome this some of the carbon dioxiderich flue gas from the exhaust of the boiler must be fed back and mixed with the oxygen diluting it and reducing the flame temperature in the process.
