A method for heating a blast furnace stove includes combusting fuel in a combustion chamber in the stove, providing combustion gases from the combustion chamber to heat refractory material in the stove, recirculating exhausted combustion gases into the combustion chamber, enriching the combustion chamber with oxygen sufficient for maintaining combustion in the combustion chamber without damaging the refractory material in the stove.

Apparatus and method for heating a blast furnace stove

A burner for a melter is provided which includes a nozzle, a fuel stream moving through the nozzle, and an oxidant stream including an initial elliptical cross section and being external to the nozzle and surrounding the fuel stream for providing a combustion stream having a cross section transitioning from an elliptical cross section to a circular cross section to provide a flat flame from the circular cross section for combustion in the melter. A method for producing a flat flame is also provided.

A metallurgical lance for introducing gas into a volume of molten material in a furnace includes a head having a bore extending therethrough, a mounting assembly at the head in the bore, and a nozzle detachably secured to the mounting assembly by a connection, the nozzle adapted to coact with a tool releasably engagable with the nozzle to insert and withdraw same from the lance head through the bore without dismantling the nozzle.

In an industrial glass furnace which contains recuperators, regenerators, electric boost or other devices for providing heat to glass batch material an oxy-fuel burner mounted in the roof of the furnace provides additional heat to melt the batch material. A method of mounting and using such a roof-mounted oxy-fuel burner including the operating parameters to maximize heat transfer while minimizing the disturbance of the batch material is disclosed.

Method of boosting a glass melting furnace using a roof mounted oxygen-fuel burner

In an industrial glass furnace, which optionally contains recuperators, regenerators, electric boost or other devices for providing heat to glass batch material, at least one staged combustion oxy-fuel burner is mounted in the roof of the furnace to provide heat to melt the glass batch material by providing a flow of fuel to the oxy-fuel burner; providing a flow of gaseous oxidant in association with said the oxy-fuel burner; injecting the fuel and the oxidant into the furnace; and, combusting the fuel such that at least a portion of combustion is effected in the vicinity of said glass forming material to enhance convective and radiative transfer of heat to said glass forming material without substantially disturbing the glass forming material. In one embodiment, the oxy-fuel burner is adapted for injecting liquid fuels. In another embodiment, the oxy-fuel burner is adapted for fuel staged combustion and contains at least one outer oxidant injector and two inner fuel injectors, the innermost fuel injector being adapted for high velocity fuel injection and the other fuel injector, disposed between the innermost fuel injector and the outer oxidant injector, being adapted for lower velocity fuel injection.

A method of heating a surface provides for a central fuel rich jet having a peripheral shroud of substantially stoichiometric combustion products and one or more fuel lean jets each having a peripheral shroud of substantially stoichiometric combustion products. The fuel lean jets are placed around the periphery of the central fuel rich jet. The fuel lean jet or jets each having shrouds of substantially stoichiometric combustion products and a careful choice of relative velocities for each results in minimizing the mixing of the fuel rich and fuel lean jets until they are at or near the surface of the material to be melted. The placement of the fuel lean jet and fuel rich jets may be reversed in applications where an oxidizing atmosphere is required at the surface to be heated.
