Q2. A cogeneration steam power plant has been modified with introducing an open feedwater heater as shown in figure below. Working pressure of the plant is between 6 MPa and 10 kPa for the boiler pressure and condensate pressure. The steam is extracted at 0.5 MPa for process heater and feedwater heater. The superheated srteam enters the turbine at 500°C at a rate of 25 kg/s and expands to the condensate pressure of 0.5 MPa. There is 60 percent of the steam is extracted from the turbine at the pressure of 0.5 MPa, and the remainder expands to a pressure of 10 kPa. Part of the extracted steam is used to heat feedwater and the rest of the extracted steam is used for process heating. The steam leaves the process heater as a saturated liquid at 0.5 MPa. It is subsequently mixed with the feedwater leaving the feedwater heater, and the mixture is pumped to the boiler pressure. The steam in the condenser is cooled and condensed by the cooling water from a nearby river, which enters the…
