Question 4 A steam power plant equipped with an open feed water heater as well as reheat arrangement, as shown in figure 1, supplies 50 kg/s of steam at 80 bar 470°C to the H.P. turbine. For feed heating, a part of steam is extracted at 7 bar and the remainder of the steam is reheated to 350°C in a reheater and then expanded in L.P. turbine down to 0.035 bar. The isentropic efficiency of both turbines is 0.85: A....

A steam power plant is based on the Rankine cycle with reheat (refer to the figure below). Steam is produced by the boiler/superheater (H-1) at 100 bar and 600 C at a rate of 2.5 kgs. This is expanded to 10 bar in the turbine T-1 and then reheated to 600 °C in heater H-2. The steam is then expanded in turbine T-2 to a pressure of 0.1 bar. The steam is then condensed in condenser (C-1) which operates at...

01: Steam enters the first turbine at 15.0 MPa and 600°C. The pressure in the condenser is 20.0 kPa. While some steam is extracted from the high-pressure turbine at 5 MPa and sent to the closed feedwater heater, the remaining steam is reheated to 600°C. The extracted steam is condensed as saturated liquid at 5.0 MPa and trapped to the open feedwater heater. Some steam is extracted from the lower-pressure turbine at 1.0 MPa and sent to the open feedwater...
