摘要： A gas burner system for providing a thin, flat flame for use in a long narrow combustion space, has a first air supply plenum which has a long narrow rectangular cross-section, which is placed above a second plenum or combustion chamber of substantially the same cross-section. At the junction between the first and second plena there are longitudinal projections inwardly from both long walls of the second plenum, forming a long narrow rectangular inlet to the second plenum. A burner assembly comprising an elongated flattened pipe having a plurality of short air baffles welded on each side is supported in this narrow inlet to the second plenum and substantially in the center thereof. The overall width of the burner assembly is less than that of the inlet so that there are two longitudinal gaps between the burner assembly and the projections for the passage of combustion air. There are two sets of ports in the lower edge of the flattened pipe. A first set provides downstreamwardly and outwardly projecting ports for the passage of the major gas flow. A second set of smaller gas ports are drilled substantially laterally to the vertical, and the gas therefrom flows into the space behind the air baffles where a stable, sheltered flame can be provided, for continuous ignition of the major flow of gas issuing at high velocity from the first set of ports, and turbulently mixing with the air flow downwardly through the gaps. The walls of the second plenum and projections can be of conventional refractory material, or they can be of metal which is water cooled.

摘要： A premix-type gaseous fuel burning system for alternate or simultaneous combustion of low BTU gas and normal BTU gas comprises a gas supply means for providing both high BTU gas and low BTU gas at selected substantial velocity, and a burner tube for receiving said gas, whereby primary air is inducted into the burner tube and mixed with the gas flow. A burner head comprises a long narrow rectangular structure of tapered construction that is inserted upwardly into a corresponding rectangular opening in the floor of the furnace. The opening is also tapered in the same direction as the burner head, but with a selected annular spacing between the walls of the opening and the burner head. Means are provided for vertically adjusting the position of the burner head within the opening. Secondary combustion air is directed through the annular space between the burner head and the opening in the floor of a furnace.

摘要： A low NO.sub.x burner for a furnace and a method of operating the burner involving a primary and secondary combustion zone wherein staged fuel and air to both combustion zones is provided. By injection of from about 40 to 60% of the liquid or gaseous hydrocarbon fuel along with about 90% of the total air required to a first reaction zone and injection of the remaining fuel with the remaining 10% of the air to a secondary reaction zone the formation of NO.sub.x is significantly suppressed. Such a burner is useful in minimizing NO.sub.x emissions for a variety of furnace types including both natural draft and forced draft furnaces.

摘要： A process for the production of reducing gases and apparatus for use therein is provided. A unique gas mixer and reactor is provided which can be used to effect substoichiometric reactions of gaseous reactants to produce a hydrogen rich gas. The gases which are to be reduced are then admixed with the hydrogen rich gas and the gaseous mixture is passed to a catalytic reactor where the reduction reaction takes place.

摘要： A gas mixer and reactor is provided which includes an elongated gas flow chamber with a nozzle arrangement at its inlet end for passing a first gaseous reactant into the interior of the chamber, toward the outlet of the chamber from points uniformly about the inner periphery of the chamber, and an annular nozzle arrangement near the outlet of the gas flow chamber for directing another gaseous reactant, or reactants, through the outlet of the gas flow chamber and into a thermal reaction chamber which communicates with the outlet of the gas flow chamber. In this manner controlled amounts of gaseous reactants may be thoroughly admixed and reacted to produce an atmosphere of desired composition. Atmospheres for kilns having controlled amounts of free hydrogen, carbon monoxide, oxygen, or carbon for example, are produced by burning controlled ratios of fuel, air and in some cases an inert gas, mixed by the reactor.
