A. You are kindly request to solve the following problem.
Consider an ideal steam regenerative Rankine cycle with two feedwater
heaters, one closed and one open. Steam enters the turbine at 10 MPa
and 500 C and exhausts to the condenser at 10 kPa. Steam is extracted
from the turbine at 0.7 MPa for the closed feedwater heater and 0.3 MPa
for the open one. The extracted steam leaves the closed feedwater heater
and is subsequently throttled to the open feedwater heater. Show the
cycle on a T-s diagram with respect to saturation lines, and using only
the data presented in the data tables given below determine
a) the fraction for steam leaving the boiler that is extracted at 0.3
MPa z=0.1425
b) the fraction of steam leaving the boiler that is extracted at 0.7
MPa y=0.06213
c) the heat transfer from the condenser per unit mass leaving the
boiler
q_out=1509 kJ/kg
d) the heat transfer to the boiler per unit mass leaving the boiler
qin=2677 kJ/kg
e) the mass flow rate of steam through the boiler for a net power
output of 250 MW m'=214.1 kg/s
f) the thermal efficiency of the cycle. Eta_th=0.4363
