Sep 17 2017 · A simple steam plant works on Rankine cycle. In the first step water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a boiler which converts it into high pressurized super heated steam. This high energized steam passes through steam turbine (a mechanical device which converts flow energy of fluid into mechanical energy) and
