Abstract
When primary fuel for combustion is combined with an amount of oxygen in excess of the stoichiometric amount required for complete combustion, in the ports of a glassmaking furnace, additional fuel is injected into the melting chamber to consume at least a portion of the excess oxygen and reduce at least a portion of NO.sub.x present in the melting chamber, to thereby reduce or suppress NO.sub.x emissions from the furnace.
