Explanation: Work output(turbine) = h1-h2 6. Which of the following contributes to the improvement of efficiency of Rankine cycle in a Thermal Power Plant?
A. reheating of steam at intermediate stage
B. regeneration use of steam for heating Boiler feed water
C. use of high pressures
D. all of the mentioned
Answer:A
Explanation: Work output(turbine) = h1-h2 6. Which of the following contributes to the improvement of efficiency of Rankine cycle in a Thermal Power Plant?
A. reheating of steam at intermediate stage B. regeneration use of steam for heating Boiler feed water C. use of high pressures D. all of the mentioned
Explanation: The regenerative features effectively raise the nominal cycle heat input temperature, by reducing the addition of heat from the Boiler/fuel source at the relatively low feedwater temperatures that would exist without regenerative feedwater heating.
