Energy Conversion Process Coal to Electricity ... Modern coal fired power station boilers are known as water tube type boilers. That is water and/or steam passes through the tubes of the boiler as opposed to fire passing through the tubes in a traditional "locomotive"type boiler or fire tube boilers. The process set out below refers to

(d) Excludes the energy of the coal and natural gas to the power plant. (e) Includes the coal and natural gas fed to the power plant since these resources are consumed within the boundaries of the system. Because the energy in the coal is greater than the energy delivered as electricity, the life cycle efficiency is negative.

How a Coal Plant Works. Coalfired 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. Here's a real ...
