A 900-MW supercritical single-reheat steam power plant operates with the main (live) steam condition of 250 bars and 560°C and the condenser pressure of 0.04 bar. The steam is reheated at a pressure of 30 bars to a temperature of 560°C. The turbine isentropic efficiency is 0.92. The feed pump work consumption may be ignored. Calculate: (a) the plant net specific work, (b) the plant thermal efficiency, (c) the plant steam flow rate, and (d) the plant heat rate.
Biomass is used as fuel to power the following cogeneration plant on a school. The turbine drives an electric generator to produce electricity, and part of the steam is extracted to provide heating to campus buildings. The boiler provides 106 kg/h of steam at 6 MPa, 520 °C, of which 4x105 kg/h is extracted between the first and second turbine stages at 1 MPa and diverted to the building heating load. Condensate returns from the building heating load at 0.95 MPa, 115 °C, and it is mixed with liquid exiting the lower pressure pump at 0.95 MPa. The entire flow is then pumped to the boiler pressure. Saturated liquid at 6 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 89 and 85%, respectively. The efficiency of the electric generator is 93% for converting turbine mechanical power into electricity. Calculate the heating load in kJ/h. Calculate the electric power generated in MWe.
A steady-state system for producing power consist of a pump, heat exchanger and a turbine. Watersteam power plant operates on an ideal reheat– regenerative Rankine cycle. Steam enters the highpressure turbine at 10 MPa and 550°C and leaves at 0.8 MPa. Some steam is extracted at thispressure to heat the feedwater in an open feedwater heater. The rest of the steam is reheated to500°C and is expanded in the low-pressure turbine to the condenser pressure of 10 kPa.
