Which of the following types of coke ovens are heated from outside and the heat
required for carbonisation is transmitted through the side walls?
-
A.
Beehive ovens
-
B.
Flatter and wider ovens
-
C.
Non recovery ovens
-
D.
Slot type by-product recovery ovens
Correct Answer:
D. Slot type by-product recovery ovens
Explanation:
Slot-type by-product recovery ovens are designed as narrow, tall refractory chambers where coal is carbonized by heat transferred through the side walls. Unlike beehive ovens, where heat is generated internally by burning the coal's volatile matter, slot-type ovens are heated externally by burning gas in flues located between the oven walls. This indirect heating method allows for the collection of volatile gases and chemical by-products, which are drawn off through an outlet rather than being consumed during the process. This design facilitates a more controlled, efficient carbonization process suitable for large-scale industrial steel production.
