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

Prevention of clinker formation in the oven

All of these

Controlling the dust nuisance while charging the coal

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)
