ABSTRACT
When fresh fuel is charged into a hot furnace the moisture and volatile matter are first distilled off. The combustible matter in the volatile matter, along with the carbon monoxide (CO) and hydrogen formed by reactions of hot carbon with carbon dioxide (C02) and water, bums in the free space above the fuel bed that, in the final analysis, consists chiefly of carbon. Combustion within fuel beds is concerned largely with reactions involving oxygen of the air and hot carbon.
