H.W. 3.1 Find the cycle efficiency and specific steam consumption of a reheat
cycle operating between pressures of 3 MPa and 0.004 MPa, with superheat temp
of 450°C. Assume that the first expansion is carried out to the point where the
steam is dry saturated and then the steam is reheated to the original superheat temp.
The feed pump term may be neglected.
H.W. 3.2 A smaller power plant produces steam at 3 MPa, 600•C, in the boiler. It
keeps the condenser at 45 C by the transfer of 10MW out as heat transfer. The first
turbine section expands to 500 kPa, and then flow is reheated followed by the
expansion in the low-pressure turbine. Find the reheat temperature so that the
turbine output is saturated vapor. For this reheat, find the total turbine power
output and the boiler heat transfer.
