Fuel gas production: true/false statement about water gas formation Statement: “Water gas is obtained by passing air and a large amount of steam over waste coal at about 650°C.” Decide whether this statement is correct.

ConceptWater gas (CO + H₂) is produced by passing steam over red-hot coke (typically near 1000°C). Air is not used during the water-gas reaction stage because oxygen would burn carbon to CO₂, lowering CO yield. Air–steam mixtures over fuel beds yield producer gas or semi-water gas, not pure water gas.
