Question

Consider a steam power plant operating on the ideal

reheat Rankine cycle. Steam enters the high-pressure

turbine at 15 MPa and 600°C and is condensed in the

condenser at a pressure of 10 kPa. If the moisture

content of the steam at the exit of the low-pressure

turbine is not to exceed 10.4 percent, 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.

Answer 1

Answer:

Consider a steam power plant operating on the ideal Rankine cycle with reheat between the pressure limits of 30 MPa and 10 kPa with a maximum cycle temperature of 700∘C and a moisture content of 5 percent at the turbine exit.
