Regenerators are used for waste heat recovery in____________________?
Correct answer: A. By-product coke ovens
- A. By-product coke ovens
- B. Beehive coke oven
- C. Blast furnace stoves
- D. Soaking pits
Explanation
By-product coke ovens use regenerative arrangements to recover heat from hot waste gases and preheat the combustion air. Beehive ovens have simpler construction, while blast-furnace stoves are primarily hot-blast heating units rather than the intended answer here.
