Boiler and Condenser Pressures - Rankine Cyc
The process of superheating is the only way to increase the peak temperature of the Rankine cycle (and to increase efficiency) without increasing the boiler pressure. This requires the addition of another type of heat exchanger called a superheater, which produces the superheated steam. Rankine cycle with superheat of the high-pressure stage.Get a Quote

Thermodynamics eBook: Ideal Regenerative Rankine Cyc
In an ideal regenerative Rankine cycle with an open feedwater heater, steam from the boiler (state 5) expands in the turbine to an intermediate pressure (state 6). At this state, some of the steam is extracted and sent to the feedwater heater, while the remaining steam in the turbine continues to expand to the condenser pressure (state 7).Get a Quote
