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 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 an ideal reheat–regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. Steam enters the turbine at 10MPa and 550C and is con- densed in the condenser at a pressure of 10 kPa. Some steam is extracted from the turbine at 4 MPa for the closed feedwater heater, and the remain- ing steam is reheated at the same pressure to 550C. The extracted steam is completely condensed...
Water is the working fluid in an ideal regenerative Rankine cycle with one open feed water heater, Figure 2. Upstream of the high pressure turbine superheated vapour with a mass flow rate of 90 kg/s entres the first-stage turbine at a pressure of 14 MPa Each turbine stage has an isentropic efficiency of 90%. The temperature of the inlet vapour is 520°C. The steam expands through the first-stage turbine to a pressure of 0.9MPa where some of the steam is...

SP-25 Consider a regenerative steam power plant with one open feedwater heater and one closed feedwater heater. Superheated steam enters the turbine with a mass flow rate of 120 kg/s at 16 MPa and 560°C (State 1). Some fraction of the steam is extracted at 40 bar (State 2) and is supplied to the closed feedwater heater. The remaining steam expands to a pressure of 3 bar (State 3), another fraction is extracted at this pressure, and is supplied to...

1) A steam power plant operates on an ideal reheat regenerative Rankine cycle with one reheater and two open feedwater heaters. Steam enters the high pressure turbine at 100 bar and 600°C and leaves the low-pressure turbine at 0.1 bar. Steam is extracted from the turbine at 17 and 3 bar, and it is reheated to 550°C at a pressure of 10 bar. Water leaves both feedwater heaters as a saturated...
3. A water vapor thermoelectric plant operates in the
regenerative Rankine cycle with two open feed water heaters as
shown in the figure. The plant maintains the turbine inlet at 10
MPa and 600 ° C, and operates the condenser at 5 kPa. Steam is
drawn from the turbine at 0.6 and 0.2 MPa. The water comes out of
both feed water heaters as a saturated liquid. The isentropic
efficiency for the turbine and the pumps is 90%. For a...
