Design a steam power plant that works as an ideal Regenerative Rankine cycle with 2 closed feedwater heaters cascaded backwards by selecting their extraction pressures to optimize cycle efficiency. The available steam conditions at the exit of the boiler are 3 MPa and 590 °C and the condenser pressure is 20 kPa. The steam flow rate at the inlet of the turbine is 80 kg/s. A T-s diagram for the cycle should be provided along with a table showing the pressure, temperature, enthalpy and entropy of all the states at the optimized point. Also, mention the net power output and rate of heat rejected from the cycle as well as the fractions of the working fluid extracted for each feedwater heaters at the design point.

A steam power plant operates on a regenerative Rankine cycle with two feedwater heaters, one closed and one open. Steam enters the turbine at 12.5 MPa and 550ºC and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 1 MPa for the closed feedwater heater and 0.8 MPa for the open one. The feedwater is heated to the condensation temperature of the extracted steam in the closed feedwater heater. The extracted steam leaves the closed...

A proposed steam power plant design consists of an ideal Rankine cycle with reheat and 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 an open feedwater heater while the remainder is reheated to T3 before entering Turbine 2. The condenser operates at P4. Saturated liquid exits the condenser and is fed to Pump 1. The outlet of Pump...
