Ceramic recuperators compared to metallic recuperators for the same duty_________________?
Correct answer: B. Occupy more space
- A. Are lighter
- B. Occupy more space
- C. Are less costly
- D. Have higher pressure differential between flue gas & air side
Explanation
Ceramic recuperators withstand higher temperatures but require thicker, more fragile construction and often have lower heat-transfer compactness than metallic units. For the same duty, this generally makes them occupy more space.
