A steam power plant design details are supplied as follows. The boiler
tubes can withstand pressures 6.3 MPa and to a maximum temperature of 460 0C.
The condenser operates at 66 0C. The pumps and turbines available can handle only
single-phase materials, and they operate isentropically. Is there a need for any reheat
for this cycle? If so, how many stages of reheat are needed? What is the maximum
temperature at the exit of the last heater? What is the overall cycle efficiency?

A steam power plant runs on a reheat Rankine cycle. Steam enters both the high and low pressure turbines at 500oC. The maximum and minimum pressures of the cycle are 10 MPa and 10 kPa, respectively. Steam leaves the condenser as a saturated liquid. The moisture content of the steam at the exit of the low-pressure turbine is 4% if the actual expansion process is adiabatic; 8.5% if the ideal expansion process is isentropic. The isentropic efficiencies of the high-pressure...

A power plant operates on a regenerative vapor power cycle with one open feedwater heater. Steam enters the first turbine stage at 12 MPa, 560°C and expands to 1 MPa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1 MPa. The remaining steam expands through the second turbine stage to the condenser pressure of 17 kPa. Saturated liquid exits the open feedwater heater at 1 MPa. The net power output for the...

A steam power plant operates with a high pressure of 4 MPa and has a boiler exit at 600C recieving heat from 700C reservoir. The ambient air at 20C provides cooling to maintain the water/vapor mixture in the condenser at 60C. All components are ideal (reversible) except the turbine which has an efficientcy 92% of a reversible, isentropic process. other than that the irreversibility of the turbine, the power plant can be considered as a Rankine cycle.
