  • Patent number: 4245980
    Abstract: A burner for reduced NOx emission and also for the control of the shape of the flame as regards its length and spread, comprises a first combustion zone, which is contained within a cylindrical chamber lined with refractory material. A burner tube is inserted through an opening in the upstream end of the first combustion zone, the burner including means for providing and burning liquid and gaseous fuel. A first air plenum is provided upstream of the first combustion zone with means for supplying less-than-stoichiometric combustion air in a tangential swirling manner, prior to entering the first combustion zone.

  • Patent number: 4237858
    Abstract: 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.

  • Patent number: 4166834
    Abstract: An improved air injector for use in feed preparation in the primary reformer of a HABER processor for ammonia synthesis. In the HABER process, process gas is introduced at relatively high velocity downwardly in a process reactor through a vertical conduit. Along the axis of the conduit is an air supply pipe with a fixture which produces a plurality of downwardly and radially outwardly directed pipes attached to a plenum on the bottom of the air pipe. In this invention the number of circumferentially spaced pipes is doubled over the prior art and they are spaced circumferentially into rows directed outwardly at about a angle so as to present, more or less, a continuous plurality of streams of air which block the annular space and force the downflowing process gas to be turbulently mixed with the air and to form a pressurized mass of process gas and air, which is then forced, by the gas pressure, to flow downwardly in, more or less, a uniform manner through a volume of catalyst.

  • Patent number: 4152108
    Abstract: 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.

  • Patent number: 3958922
    Abstract: A duct burner primarily for use in raising the temperature of turbine exhaust gas (TEG) to a usable temperature to operate a steam generator or the like. The burner comprises an array of downstream facing burners capable of burning low grade fuel oil in a low oxygen environment, each burner being provided with gas burning backup and individual flame scan capabilities.
