Steam is generated in the boiler of a cogeneration plant at 4 MPa and 480oC at a rate of 7 kg/s. The plant is to produce power while meeting the process steam requirements for a certain industrial application. One-third of the steam leaving the boiler is throttled to a pressure of 820 kPa and is routed to the process heater. The rest of the steam is expanded in an isentropic turbine to a pressure of 820 kPa and is also routed to the process heater. Steam leaves the process heater as saturated liquid. Determine:
The net power produced and
The rate of process heat supply.
