H.W 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. [Answer. (Reheat temperature= 529°C , total turbine power output= 6487 kW, the boiler heat transfer= 16 475 kW)]

Question
Н.W 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. [Answer. (Reheat temperature= 529°C , total turbine power output= 6487 kW, the boiler heat transfer= 16 475 kW)]
