May 10, 2012 · A simple steam turbine CHP system needs a boiler and steam generator to raise the steam to drive the unit. The fuel can be any fossil fuel as well as biomass fuels. For highest electrical conversion efficiency, the steam will be condensed at the exit of the steam turbine, creating the largest pressure drop possible across the turbine blades.

A steam heating system takes advantage of the high latent heat which is given off when steam condenses to liquid water. In a steam heating system, each room is equipped with a radiator which is connected to a source of low-pressure steam (a boiler). Steam entering the radiator condenses and gives up its latent heat, returning to liquid water.
