High rate of heating of coke ovens____________________?
Correct answer: A. May damage its walls due to abrupt excessive swelling of coal
- A. May damage its walls due to abrupt excessive swelling of coal
- B. Produces larger size coke
- C. Increases the time of carbonisation
- D. None of these
Explanation
Rapid heating causes coal to swell abruptly while it is being carbonised, producing severe thermal and mechanical stress on the oven walls. It can therefore damage the walls, making option A the valid effect.
