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).

DetailsQuestion: 10-102: Consider an ideal reheat-regenerative Rankine cycle with one open feedwater heater. The boiler pressure is 10 MPa, the condenser pressure is 15 kPa, the reheater pressure is 1
DetailsSep 29, 2014· Sample Problem A steam power plant operates on an ideal reheat-regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. The fractions of stream extracted from turbines and the thermal efficiency of the cycle are to be determined. Assumptions: All the components in the cycle operate at steady state.
Details9-1-27 [regen-14MPa] Consider a steam power plant operating on the ideal regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 14 MPa, 610 o C and is condensed in the condenser at a pressure of 12 kPa.
DetailsQuestion: Consider a reheat-regenerative Rankine cycle with one open feedwater heater. The boiler pressure is 10 MPa, the condenser pressure is 1 MPa, and the feedwater pressure is 0.6 MPa.
DetailsMar 04, 2020· Rankine Cycle with Closed Feed Water Heaters. Rankine cycle with closed feed water heaters are having its benefits and is most commonly used in all modern power plants. Closed feed water heater employs indirect mode of heat transfer, i.e extracted steam or bleed steam from the turbine transfers its heat indirectly to feed water in shell and tube heat exchanger.
DetailsFeb 25, 2013· Exercise 5Consider a steam power plant operating on theideal regenerative Rankine cycle with one openfeedwater heater. Steam enters the turbine at15 MPa and 600°C and is condensed in thecondenser at a pressure of 10 kPa. Some steamleaves the turbine at a pressure of 1.2 MPa andenters the open feedwater heater.
DetailsRankine cycle, is the ideal cycle for vapor power plants. The ideal Rankine cycle does not involve any internal irreversibilities and consists of the following four processes: 1-2 Isentropic compression in a pump. 2-3 Constant pressure heat addition in a boiler. 3-4 Isentropic expansion in a turbine. 4-1 Constant pressure heat rejection in a
DetailsA steam power plant operates on an ideal reheat-regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. The fractions of stream extracted from turbines and the thermal efficiency of the cycle are to be determined. Assumptions: All the components in the cycle operate at steady state.
DetailsConcept of regenerative Rankine cycle with feedwater heater will provide better positive result in respect of increase in thermal efficiency of the Rankine cycle or in simple way we can say that thermal efficiency of the steam power cycle will be improved quite good by using the concept of regenerative Rankine cycle with feedwater heater as compared with reheat cycle.
