Increase in ash content of blast furnace coke_________________?
Correct answer: B. Increases its consumption in the furnace
- A. Reduces its consumption in the furnace
- B. Increases its consumption in the furnace
- C. Does not affect its consumption in the furnace
- D. Decreases its hardness and abrasion resistance
Explanation
Ash is an inert, noncombustible part of coke, so more ash means less effective carbon per unit mass. The furnace therefore requires more coke to supply the same heat and reducing power.
