Theory of Steam Turbines - Thermodynami

In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy.In its simplest form, a steam turbine consist of a boiler (steam generator), turbine, condenser, feed pump and a variety of auxiliary devices. Unlike with reciprocating engines, for instance, compression, heating and expansion are continuous and
