Beehive coke oven________________?
Correct answer: B. Takes 2-3 days for coking of coal but requires no external fuel for heating
- A. Facilitates by-products recovery
- B. Takes 2-3 days for coking of coal but requires no external fuel for heating
- C. Gives larger yield of coke (around 85%) as compared to by-product ovens
- D. Produces coke with very poor strength
Explanation
A beehive oven is a non-recovery coke oven: coal is coked for roughly 2 to 3 days, and the volatile gases burn inside the oven, eliminating the need for continuous external heating. It does not recover valuable by-products.
