.0- A (165 MW) Electric power is generated in a Reheat-Regenerative steam power plant. The outlet steam rate from the boiler is (3.95 kg/kW.hr) at (40 bar, 350 °C). The inlet boiler feed water temperature is (165 °C saturated). The boiler efficiency is (88%). The steam is expanded in the first stage of the turbine until it is dry at (30 bar), then it is reheated to (350 °C). (8%) of steam is extracted from the first stage of the turbine to heat the boiler feed water. Calculate the fuel mass flow rate, if the high heat value of the fuel is (31 MJ/kg).

Transcribed Image Text:10-A (165 MW) Electric power is generated in a Reheat-Regenerative steam power plant. The
outlet steam rate from the boiler is (3.95 kg/kW.hr) at (40 bar, 350 °C). The inlet boiler
feed water temperature is (165 °C saturated). The boiler efficiency is (88%). The steam is
expanded in the first stage of the turbine until it is dry at (30 bar), then it is reheated to (350
°C). (8%) of steam is extracted from the first stage of the turbine to heat the boiler feed
water. Calculate the fuel mass flow rate, if the high heat value of the fuel is (31 MJ/kg).
