Jan 01 1982 · The gas pressures are normally between 1.5 and 5 kPa gauge (15 and 50 mbar). Normal piped supply pressure is used for the smaller ratings and gas boosters are used for burners requiring the higher pressures. The combustion-air pressures are normally in the range 0.2–1 kPa gauge (2–10 mbar) but also up to 3 kPa gauge.

Coke (fuel)Wikipedia
Coke is a grey hard and porous fuel with a high carbon content and few impurities made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product used mainly in iron ore smelting but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low
