Coal-fired power generation | Sulzer

Coal- and oil-fired process. Coal- and oil-fired steam power plants have steam turbines to convert the heat energy of combustion into mechanical energy, which then operates an electric generator. All plants use the steam turbine for the drop between the high pressure and temperature of the steam and the lower pressure of condensing vapor.
