Steam power plant using the reheat Rankine cycle
A steam power plant operates using the reheat Rankine cycle. Steam enters the high pressure turbine at 12.5 MPa and 550ºC at a rate of 7.7 kg/s and leaves at 2MPa. Steam is then reheated at a constant pressure to 450ºC before it expands in the low pressure turbine. The isentropic efficiencies of the turbine and the pumpare 85% and 90%, respectively. Steam leaves the condenser as a saturated liquid. If the moisture content of the steam at the exit...

20 E2) An idealized reheat-regenerative vapour power cycle having two feedwater heaters (one closed, one open) operates with a boiler delivery pressure and temperature of 8.0 MPa and 480 °C, respectively. A portion of the steam, y, is extracted at 2.0 MPa after the first turbine expansion stage for the CFWH. The remainder expands to 0.7 MPa and is then reheated to 440°C. The reheated steam then enters the third turbine stage, expands to 0.3 MPa and has a portion,...

Problem 8.021 Tutorial S1 Water is the working fluid in an ideal Rankine cycle with reheat. Superheated vapor enters the turbine at 12 MPa, 440C, and the condenser pressure is 8 kPa. Steam expands through the first-stage turbine to 1.2 MPa and then is reheated to 480°C. Assume the pump and each turbine stage has an isentropic efficiency of 85% and 92%, respectively. Determine for the cycle: (a) the rate...

A steam power plant operates on the reheat Rankine cycle. Steam enters the high-pressure turbine at 12.5 MPa and 5508C at a rate of 7.7 kg/s and leaves at 2 MPa. Steam is then reheated at constant pressure to 400 C before it expands in the low-pressure turbine. Steam leaves the condenser as a saturated liquid. The exit of the turbine is saturated at the condenser pressure (a) the condenser pressure, (b) the net power output, and (c) the thermal...

a) A steam power plant operates on an ideal reheat-regenerative Rankine cycle. Steam enters the high-pressure turbine (HPT) at a pressure of 10 MPa and temperature of 550°C. The steam expands through the HPT stage to a pressure of 0.6 MPa. Some of the steam at the end of the expansion process in HPT is extracted for a regeneration process in a closed-type feedwater heater. The steam leaves the heater as a saturated liquid and then is throttled to the...

Consider a regenerative vapor power cycle with two feedwater heaters, a closed one and an open one, and reheat. Steam enters the first turbine stage at 12 MPa, 480°C, and expands to 2 MPa. Some steam is extracted at 2 MPa and fed to the closed feedwater heater. The remainder is reheated at 2 MPa to 440°C and then expands through the second-stage turbine to 0.3 MPa, where an additional amount is extracted and fed into the open feedwater heater...
