Consider a cogeneration system operating as shown in the figure. The steam generator provides 1.2x106kg/h of steam at 8 MPa, 480C. Steam is extracted between the first and second turbine stages at 1 MPa and diverted to a process heating load. The process heating load is 9.5x108 kJ/h. Condensate returns from the process heating load at 0.95 MPa, 120C and is mixed with liquid exiting the lower-pressure pump at 0.95 MPa. The entire flow is then pumped to the steam generator pressure. Saturated liquid at 8 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 86 and 80%, respectively.
