A steam power plant operating on a regenerative cycle, as illustrated in Fig. 8.5, includes two feedwater heaters. Steam enters the turbine at 6500 kPa and 600°C and exhausts at 20 kPa. Steam for the feedwater heaters is extracted from the turbine at pressures such that the feedwater is heated to 190°C in two equal increments of temperature rise, with 5°C approaches to the steam-condensation temperature in each feedwater heater. If the turbine and pump efficiencies are each 0.80, what is the thermal efficiency of the cycle, and what fraction of the steam entering the turbine is extracted for each feedwater heater? kindly answer it with full explanation of the solution, thankyou
A steady-state gas turbine is using air as the working fluid has shaft power output of 55 MW. Air enters the turbine at 300 K and leaves at 600 K and 30 m/s. The air is first compressed by adding a compression power of 15 MW. Then air receives 173 MW as heat input from the combustor. Determine the mass flow rate of air in kg/s.
Consider a thermal power plant with reheating and cogeneration. It produces 5 MW of power and 4 MW of process heat. The steam enters the high-pressure turbine at 8 MPa and 480 °C and expands to 1.2 MPa, to be reheated to 450 C. Subsequently, at a pressure of 0.8 MPa, a fraction of 0.152 of steam is extracted, which is sent as process heat. Then, at a pressure of 0.25 MPa, another extraction is made to preheat feed water in a closed heater, whose condensate (saturated liquid) expands and is sent to the condenser, whose pressure is 15 kPa, from which saturated liquid comes out. Subsequently, it is pumped to a mixer where it joins with the subcooled liquid at 120 C and 0.8 MPa that comes from the industrial process, to be later pumped to the steam generator.
