Fuel consumption in coke making can be reduced by___________________?
Correct answer: D. All A., B. and C.
- A. Preheating, blending and de-ashing the coal
- B. Stamped charging of coal
- C. Dry quenching of coke
- D. All A., B. and C.
Explanation
Coal preheating, blending and de-ashing improve carbonisation efficiency, stamped charging increases bulk density, and dry quenching recovers sensible heat. Each measure can reduce fuel requirements, making the combined option correct.
