1 Kg 5 Consider The Following Steam Power Plant That Operates On An Ideal Reheat Regenerative Rankine Cycle With Feedwat 1 (144.12 KiB) Viewed 16 times

1 kg 5 Consider the following steam power plant that operates on an ideal reheat-regenerative Rankine cycle with feedwater heater, feedwater pump, and reheater. Steam enters the turbine at 20 MPa and 650°C and is condensed in the condenser at a pressure of 30 kPa. Some steam is extracted from the turbine at 5 MPa for the feedwater heater, and the remaining steam is reheated at the same pressure to 550°C. The extracted steam is completely condensed in the heater and is pumped to 20 MPa before it mixes with the feedwater at the same pressure. Steam for the open feedwater heater is extracted from the low-pressure turbine at a pressure of 1 MPa. Qin (Note: Steam traps are a type of automatic valve that filters out condensate and non-condensable gases such as air without letting steam escape. Steam traps are used in some industrial applications to ensure that steam is not wasted) Find the following parameters (approximately): h₂ = kJ/kg h4 = ( kJ/kg h6 = kJ/kg hg = kJ/kg % hg = kJ/kg Wnet = Qin = nth = kJ/kg kJ/kg 20 kPa HP LP 650°C Turbine Turbine 5 MPa 'y' kg 5 MPa, 550°C 'y' kg Trap Wout 1 MPa z' kg Ferd-water Heater Fini 130 kPa Qout
