17,5 MPa 575 CHAPTER 10 EXAMPLE 10-6 The Ideal Reheat-Regenerative Rankine Cycle Consider a steam power plant that operates on an ideal reheat-regenerative Rankine cycle with one open feedwater heater, one closed feedwater heater, and one reheater. Steam enters the turbine atand 600°C and is con- densed in the condenser at a pressure of Some steam is extracted, 5 kPa SMPa from the turbine at for the closed feedwater heater, and the remain- - 5LPa is > 17, 5MPA , ing steam is reheated at the same pressure to 600°C. The extracted steam mixes with the feedwater at the same pressure. Steam for the open feed- water heater is extracted from the low-pressure turbine at a pressure of 0.5 MPa. Determine the fractions of steam extracted from the turbine as well as the thermal efficiency of the cycle.
