Sensible heat of hot industrial flue gases cannot be recovered by a/an________________?
Correct answer: C. None of these
- A. Economiser
- B. Regenerator
- C. None of these
- D. Ceramic recuperator
Explanation
An economiser, regenerator, and ceramic recuperator can all recover sensible heat from hot flue gas by transferring it to incoming feed, combustion air, or another process stream. Therefore none of the listed devices is excluded.
