2) A cogeneration plant with a simple steam power plant topping cycle (single turbine, condenser, pump, and boiler, with no reheat or regeneration) is used to generate process heating for a refinery. The turbine inlet is at a pressure 18 MPa and temperature 823 K. The turbine outlet pressure is 0.2 MPa, and the turbine isentropic efficiency is 0.9. The boiler is heated by the combustion of a fuel of heating value 40 MJ/kg that flows at a rate of 21.5 kg/s. The boiler combustion efficiency no is 0.95, the electric generator efficiency is 0.98, and the fraction of power plant rejected heat converted to useful process heat is 0.85. a.
