| Consider a steam power plant operating on the reheat Rankine cycle. Steam enters the high pressure turbine at 16 MPa and 550oC, is condensed in the condenser at 10 kPa. If the moisture content of the steam at the exit of the low pressure turbine is not to exceed 5%, determine (a) the pressure at which the steam should be reheated, and (b) the thermal efficiency of the cycle. Assume the steam is reheated to the inlet temperature of the high pressure turbine.(c) What-if-scenario: How would the answer in (b) change if the moisture tolerance of the turbine were increased to 10%? --------------------------------------- Answers: (a) 1.29 MPa, (b) 43.9 %, (c) 44.3 % | |
