ABSTRACT:
Process and apparatus for firing a furnace using oxygen or oxygen-enriched air as the oxidant gas, comprising injection into the furnace of a plurality of oxidant jets, through nozzles, in a spaced relationship to a fuel jet, at a velocity sufficient to cause aspiration of furnace gases into the oxidant jets before the latter mix with the fuel jet, in amounts sufficient to lower flame temperature.
