Q. The temperature of feed water can be increased in following two ways in a regenerative Rankine cycle
i) by passing feed water around turbine casing in direction opposite to flow of steam
ii) by bleeding certain portion of steam at the end of h.p expansion & mixing with condensate to make feed water at the temperature of boiler

  • (A) i) is preferred over ii) for higher efficiency
  • (B) ii) is preferred over i) for reduced moisture content of steam in l.p side
  • (C) only i) is implemented in actual practice
  • (D) by preferring ii) overi) significant gain in efficiency results
