Steam enters the high-pressure turbine in a steam power plant with a mass flow rate of 200000 kg/h at atemperature of 700°C and a pressure of 10 MPa. The steam

is expanded to a pressure of 3 MPa where24.39% of the steam is extracted for use in a feedwater heater; the remainder expanded to a reheatpressure of 1 MPa. This steam is reheated to a temperature of 500°C, and is then expanded to thecondenser pressure of 10 kPa. Boiler feedwater leaves a mixing chamber at the boiler pressure and entersthe steam generator as liquid at a temperature of 230.52°C. Flue gas enters the steam generator with amass flow rate of 532861 kg/h and can be assumed to have a specific heat of 1.2938 kJ/kg K. Assume avalue of 4.178 kJ/kg•K as the specific heat of the boiler feedwater, and that the turbines have an isentropicefficiency of 95%, and the pumps have an isentropic efficiency of 85%. Set the approach pointtemperature difference and the pinch point temperature difference to 30°C and 25°C, respectively. Thepower plant burns propane (C3H8) as the fuel with 110 % excess air. (a) The temperature of the flue gas at all stages (b) The rate of heat transfer for the boiler, superheater, reheater, and economizer. (c) Construct the temperature-duty diagram, indicating all temperatures.
