Reheat cycle in steam power plant is used to________________?
Correct answer: B. increase thermal efficiency
- A. utilise heat of flue gases
- B. increase thermal efficiency
- C. improve condenser performance
- D. reduce loss of heat
Explanation
Reheating expands steam in stages and returns it to the boiler for reheating between stages, raising the average temperature of heat addition and improving cycle efficiency. It also reduces moisture at the turbine exhaust, although that benefit is not listed.
