Combined Gas-Vapor Power Cycle: (ANALYSIS)
Consider a combined gas-steam power cycle. The topping cycle is a
simple Brayton cycle that has a pressure ratio of 8. Air enters the
compressor at 20°C at a rate of 40 kg/s and the gas turbine at 950°C.
The bottoming cycle is a Reheat Rankine cycle between the pressure
limits of 6 Mpa and 12.5 kPa. Steam is heated in a heat exchanger at a
rate of 4.8 kg/s by the exhaust gases leaving the gas turbine, and the
exhaust gases leave the heat exchanger at 200°C. Steam leaves the
high-pressure turbine at 1.0 MPa and is reheated to 400°C in the heat
exchanger before it expands in the low-pressure turbine. Assuming
85% isentropic efficiency for all pumps and turbines,
determine
(a) the moisture content at the exit of the low-pressure turbine,
(b) the steam temperature at the inlet of the high-pressure turbine,
(c) the net power output and the thermal efficiency of the combined
plant](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fabae9954-85d7-4b3c-90d6-97e916b83df7%2F11356725-f2e7-4b46-bd80-2e93e8c774c4%2Fmpap9b_processed.jpeg&w=3840&q=75)
