Consider a Rankine cycle with an ideal intermediate steam pickup, one of which is open and the other is closed feed water heaters. The steam enters the turbine at 12.5 MPa pressure and 550 degrees Celsius temperature and expands to 10 kPa condenser pressure. The steam separated from the turbine at 0.8 MPa pressure is sent to the closed feed water heater and the steam separated at 0.3 MPa pressure is sent to the open feed water heater. The feed water is heated to the condensing temperature of the steam leaving the turbine in the closed heater. The steam comes out of the closed heater as a saturated liquid, then the pressure is lowered into a valve and sent to the open feed water heater. Show the cycle in a T-s diagram with saturated liquid and saturated vapor curves.

a)

Water flow that must pass through the boiler for the production of 250 MW net power,

b)

Calculate the thermal efficiency of the cycle.

Consider a steam power plant operating on a simple ideal Rankine cycle in which the steam enters the turbine at 3 MPa and 350C and is condensed in the condenser at 75 kPa. Determine the thermal efficiency of this cycle and sketch an appropriately labeled T-s diagram. Also compare this thermal efficiency to that a Carnot heat engine operating between these same two limits. The change in enthalpy across the pump = work done by the pump: h2-h1= v1(P2– P1)
