Notes on Simple Steam Power Plant - ME Mechanical

Sep 14, 2016· Simple Steam Power Plant. In a simple steam power plant, at the top of the boiler high-pressure superheated steam leaves the steam drum, also referred to as a steam generator and enters the turbine. In the turbine, steam expands and in doing so does work, which enables the turbine to drive the electric generator.
