Sometimes water is sprayed during coal charging in the coke oven, which helps in

Reducing the cracking of hydrocarbons in the gas and increasing the percentage of CO & H₂ in the gas (due to the endothermic reaction represented by C + H₂O = CO + H₂)

All of these

Controlling the dust nuisance while charging the coal

Prevention of clinker formation in the oven
