The maximum percentage gain in Regenerative feed heating cycle thermal efficiency____________?
Correct answer: A. increases with number of feed heaters increasing
- A. increases with number of feed heaters increasing
- B. decreases with number of feed heaters increasing
- C. remains same unaffected by number of feed heaters
- D. none of the above
Explanation
Adding feed heaters raises the average temperature at which heat is supplied, so the maximum efficiency gain increases as more heaters are used. The improvement from each additional heater becomes progressively smaller, but the overall gain still rises.
