Consider a cogeneration power plant modified with regeneration. Steam enters the turbine at 6 MPa and 450°C and expands to a pressure of 0.4 MPa. At this pressure, 60 percent of the steam is extracted from the turbine, and the remainder expands to 10 kPa. Part of the extracted steam is used to heat the feedwater in an open feedwater heater.

Solved: Steam Is Generated In The Boiler Of A Cogenerati

Steam is generated in the boiler of a cogeneration plant at 10 MPa and 450 degrees C at a steady rate of 5 kg/s. In normal operation, steam expands in a turbine to a pressure of 0.5 MPa and is then routed to the process heater, where it supplies the process heat. Steam leaves the process heater as a saturated liquid and is pumped to the boiler

Solved: Consider An Ideal Cogeneration Steam Plant - Che

Consider an ideal cogeneration steam plant to generate power and process heat. Steam enters the turbine from the boiler at 7 Mpa and 500 degree C. One-fourth of the steam is extracted from the turbine at 600-kPa pressure for generating 8600 kJ/s of process heat. The remainder of the steam continues to expand and exhausts to the condenser at 10 kPa.
