In regenerative cycle feed water is heated by_____________?
Correct answer: C. draining steam from the turbine
- A. exhaust gases
- B. heaters
- C. draining steam from the turbine
- D. all above
Explanation
Regenerative heating uses steam bled or drained from intermediate turbine stages to heat the feedwater in feed heaters. Exhaust gases belong to waste-heat or economizer arrangements, not the usual regenerative cycle.
