1 Introduction. In regenerative steam Rankine cycles, steam is extracted from the turbines to preheat the boiler feedwater (BFW). This preheating process elevates the temperature at which the BFW receives heat, thus increasing the thermal efficiency of the plant (defined as the ratio between the net power output from and the heat input to the plant). In practice, a finite number of closed or

A steam power plant operates on a cycle, using a turbine that receives steam at P 2 =10,000kPa and T 2 =600 o C and expands it to P 3 = expanded steam goes into a condenser that produces saturated liquid water, which is then fed in a pump to produce the compressed high pressure water goes into the boiler to produce high pressure steam.

In gas cycles, the working fluid remains in the gas phase throughout the entire cycle. In vapor cycles, the working fluid exits as vapor phase during one part of the cycle and as liquid phase during another part of the cycle. Steam power plants run vapor power cycles with water as the working fluid. This section introduces the ideal cycle for

Today, the Rankine cycle is the fundamental operating cycle of all thermal power plants where an operating fluid is continuously evaporated and condensed. It is the one of most common thermodynamic cycles, because in most of the places in the world the turbine is steamdriven.. In contrast to Carnot cycle, the Rankine cycle does not execute isothermal processes, because these must be performed
