Reheat in Rankine cycle is heating the steam which comes out from Low pressure turbine. For reheating the steam is passed through the boiler part. If we don't reheat and if we want higher pressure at turbine inlet then during expansion through tur

Dec 30, 2019 · The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing a phase change. It is an idealized cycle in which friction losses in each of the four components are neglected. The heat is supplied externally to a closed loop, which usually uses water as the working fluid.

A steam power plant operates on a Rankine cycle with high pressure of 2.0 MPa and a boiler exit temperature of 600˚C. The heat input to the boiler is 3437 kJ/kg. The condenser operates at 60˚C and the outlet of the condenser is saturated liquid. All components are ideal except the turbine, which has an isentropic efficiency of 95%.

Rankine Cycle, as shown in Figure 2. In the steam Rankine cycle, the working fluid— water—is first pumped to elevated pressure before entering a heat recovery boiler. The pressurized water is vaporized by the hot exhaust and then expanded to lower temperature and pressure in a turbine, generating mechanical power

Jan 02, 2021 · by The Science Pan. The ideal cycle for vapor power plants is the Rankine cycle. The simple ideal Rankine cycle does not involve any internal irreversibilities and consists of the following four processes: 1-2 Isentropic compression in a pump: Water is pumped from low pressure to high pressure, which is the boiler's operating pressure.

Aug 10, 2020 · The next stage of the Rankine cycle is the turbine stage which receives high temperature high pressure fluid in vapor state. Vapor enters the turbine where they expand in turbine by rotating the blades of the turbine. This process reduces both temperature and pressure of the vapors thus making the process of expansion as isentropic expansion.

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.
