Sometimes water is sprayed during coal charging in the coke oven, which helps in ________________?
Correct answer: E. All A., B. and C.
- A. Prevention of clinker formation in the oven
- B. Controlling the dust nuisance while charging the coal
- C. Reducing the cracking of hydrocarbons in the gas and increasing the percentage of CO &
- D. H2 in the gas (due to the endothermic reaction represented by C + H2O = CO + H2)
- E. All A., B. and C.
Explanation
Water spraying during charging suppresses coal dust, helps prevent clinker formation, and supplies steam that limits hydrocarbon cracking while promoting CO and H₂ formation. Therefore, all the listed effects apply.
