A steam turbine cycle running on a Rankin cycle between a condenser pressure of 10 kPa and a boiler pressure of 20 MPa, the steam enters the high pressure turbine at a temperature of 600 ° C. The average turbine expands to 800 kPa and then enters the boiler again to be reheated to 500 ° C. The steam leaves the boiler to a low pressure turbine, where it expands to the condenser pressure. If the expansion and compression in the turbine and the pump is isotropic, and the addition of heat is constant pressure, find the efficiency of the cycle. Note point # 1 at the vapor exit region of the condenser
Exhaust gases from the turbine of a simple Brayton cycle are quite hot and may be used for other thermal purposes. One proposed use is generating saturated steam at 110°C from water at 30°C in a boiler. This steam will be distributed to several buildings on a college campus for space heating. A Brayton cycle with a pressure ratio of 6 is to be used for this purpose. Plot the power produced, the flow rate of produced steam, and the maximum cycle temperature as functions of the rate at which heat is added to the cycle. The temperature at the turbine inlet is not to exceed 2000°C.
