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 fluid fuel burner system for minimum production of NOX under varying rates of fuel firing and varying rates of combustion air or oxidant supply, which comprises a fuel burner including means for burning liquid and gaseous fuel. Liquid fuels are burned in an axial burner tube, and the gaseous fuels are burned in a plurality of gas burner tubes located in a circle coaxial with the liquid burner. A first air or oxidant plenum supplies primary-plus-secondary air or oxidant, the primary air or oxidant going to the liquid burner and the secondary air or oxidant going to the gas burner. The total of primary plus secondary is less than stoichiometric flow so that the combustion of the fuel in a first combustion chamber provides a reducing atmosphere to preclude the formation of NOX. Means are provided for independently controlling the primary air or oxidant flow compared to the secondary air or oxidant flow, or vice versa. A second air or oxidant plenum provides tertiary air or oxidant to a second combustion space downstream of the first combustion chamber. Control means provide independent control of the primary-plus-secondary air or oxidant flow to the first plenum as a selected ratio to the tertiary air or oxidant, that flows to the second plenum.

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： Apparatus for burning gaseous and liquid fuels in a furnace, to retard formation of NO.sub.x, comprising a fuel tube of selected length and diameter, closed at the end which is inserted into a combustion zone. There are a plurality of ports drilled in the closed end of the fuel tube, the axes of which lie on a conical surface coaxial with the fuel tube. The fuel tube is inserted coaxially into a burner tube of selected larger diameter, and the distant ends are substantially coplanar. A plurality of jets of low pressure steam are injected through a plurality of ports into the annular space between the fuel tube and the burner tube at the outer end of the burner tube. The steam jets flowing through the ports induce a flow of primary combustion air, which mixes with the steam and flows down the annular space to mix with the high velocity jets of fuel as they emerge from the ports on the fuel tube. The fuel, air, and steam mix together prior to entering the combustion reaction zone.
