A direct-fired furnace wherein a charge-proximal stratum is established between the charge and combustion gases emanating from one or more or burners oriented above the charge, wherein the charge-proximal stratum has a different oxidative effect upon the charge than does the combustion gases.
A method for heating or melting a charge of material in a direct-fired furnace, comprising: (A) introducing said charge into said furnace to expose said charge to radiant heat from a direct-fired burner placed above said charge; (B) providing fuel and oxidant into the furnace from said direct-fired burner at a mass average velocity not exceeding 50 feet per second, and combusting the fuel and oxidant within the furnace to generate heat and to produce combustion gases; and (C) introducing a charge-proximal gas into the furnace between said direct-fired bu...
