Stage 1: The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and oxygen in the air combine to produce carbon dioxide and heat.
Stage 2: Thermodynamic process: The heat from the combustion of the coal boils water in the boiler to produce steam. The steam is the piped to a turbine. The high pressure steam impinges and expands across a number of sets of blades in the turbine. The impulse and the thrust created rotates the turbine. The steam is then condensed and pumped back into the boiler to repeat the cycle.
