Chapter 10 VAPOR AND COMBINED POWER CYCLES

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).

Thermodynamics eBook: Ideal Reheat Rankine Cycle

The Rankine cycle system consists of a pump, boiler, turbine, and condenser. The pump delivers liquid water to the boiler. The boiler heated by the solar heat converts water to superheated steam. This steam is used to run the turbine which powers the generator. Steam leaves the turbine and becomes cooled to liquid state in the condenser. Then the liquid is pressurized by the pump and goes back to the boiler. And the cycle …

Boiler and Condenser Pressures - Rankine Cycle | nuclear

Boiler and Condenser Pressures – Rankine Cycle. As in the Carnot, Otto and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature at which energy is rejected decreases. This is the common feature of all thermodynamic cycles.
