Question details

(18 mark) Q4/A steam power plant operates on ideal Rankine cycle using reheated and regenerative feed water heaters. It hàs one open feed heater Steam is supplied at (150 bar and.600 °c) The condenser pressure is (10 kpa).Some steam is extracted from the turbine at( 40 bar) for closed feed water heater and remaining steam is reheated at (40 bar to 600 °c). Extracted steam is completely condensed in this closed feed water heater with draines pumped forward and is pumped to (150 bar )before mixing with the feed water heater. Steam for the open feed water heater is bled from LP. turbine at( 5 bar). Assume the H.P turbine efficiency 80%and used TTD of (5°c) and (Neglect the pumps work). Determine: 1-Fraction of steam extracted from the turbines at each bled heater 2-Thermal efficiency Draw the line diagram of the component and represent the cycle on T-S diagram. (40 mark)
