In large steam power plants, the feed-water is frequently heated in a closed feed-water heater by using steam extracted from the turbine at some stage. Steam enters the feed-water heater at 1 MPa and 200C and leaves as saturated liquid at the same pressure. Feed-water enters the heater at 2.5 MPa and 50C and leaves at 10C below the exit
In large steam power plants, the feed-water is frequently heated in a closed feed-water heater by using steam extracted from the turbine at some stage. Steam enters the feed-water heater at 1 MPa and 200°C and leaves as saturated liquid at the same pressure. Feed-water enters the heater at 2.5 MPa and 50°C and leaves at 10°C below the exit temperature of the steam. Determine the ratio of the mass flow rates of the extracted steam and the feed-water.
