WEB4 days ago · 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.
WEBState point 2 3 is heat addition in the boiler. If you are rejecting 70% of that heat in the condenser, then your cycle efficiency is at most 30%. (Neglecting pump work, should be small compared to turbine work.) Usually, Rankine cycles are more efficient than that. Conversion of thermal energy to mechanical work is never 100%.
