You are an operating engineer in a steam power plant which is working on a regenerative Rankine cycle and you are requested to find the thermal efficiency of this cycle. You read the following data from the measuring devices used in the power plant: The pressure and temperature of the steam at the inlet of the turbine are 7000kPa and 550 °C, respectively. The pressure at the inlet of the condenser is 22 kPa. The extracted steam from the turbine is at 500 kPa and it is used to heat the feed water in an open feed water heater. The pumps and turbine efficiencies are 80% and 85%, respectively. Don't forget to show the evele on a T-s diagram.

DESIGN a steam power plant that produces 70 MW of power. The plant should have an open heater and a reheater operating simultaneously utilizing saturated steam from the partial expansion of steam in the turbine. The remaining steam is reheated to the inlet temperature of steam when it enters the turbine. Another open heater is used to bled saturated steam when the steam partially expands in the turbine after reheating, remaining steam is expanded to the exhaust pressure of the turbine. Other pertinent data are as follows: steam turbine: inlet pressure – 6.6 MPa; inlet temperature - 420 C; exhaust pressure – 10 KPa; stages of turbine – all pressure compounded stage; pumps – 90% efficient; shaftings – 75%% efficient; generator – 95% efficient.
