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...
Consider a steam power plant that operates on the ideal

the pump, and the heat...

2) A steam power plant operates on an ideal regenerative rankine cycle with superheated steam leaving the boiler, entering the turbine at 10 mPa,600C. X fraction of steam is extracted from the turbine at 0.6 mPa pressure for the high pressure open feedwater heater.

Consider a modern extra-supercritical pressure steam power plant that operates Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater, as shown below. Steam enters the high-pressure turbine at 32 MPa and 700 °C and is condensed in the condenser at a pressure of 10 kPa. Steam exits the high-pressure turbine at 4 MPa and is routed into a reheater (inside the boiler) to be reheated to 640 °C. Steam at P-8 MPa is extracted from...
A steam power plant design consists of an ideal Rankine cycle with regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder enters Turbine 2. A portion (y'') of the steam exiting Turbine 2 at P3 is diverted to an open feedwater heater while the remainder enters Turbine 3. The exit of Turbine...
