Steam Power StationsArrangement and Working

Steam is produced in the boiler by utilizing the heat of coal combustion. The steam is then expanded in the prime mover (i.e. steam turbine) and is condensed in a condenser to be fed into the boiler again.. The steam turbine drives the alternator which converts the mechanical energy of the turbine into electrical energy. Although the steam power station simply involves the conversion of the
