A snowboard support and display rack, for selectively supporting and displaying a snowboard upon a vertical support structure. The rack comprises a left engagement member and a right engagement member, each comprising a front prong, a rear prong, a junction located therebetween, and a base member contiguous with and extending perpendicularly inward from the rear prong. After attachment to the support structure of the left and right engagement members at the same height, the prongs each extend vertically upward. Each engagement member has a vertical slot defined by the prongs and the junction located therebetween, into which the snowboard is selectively lowered for support and display of the snowboard. The engagement members are separately selectively mounted to the vertical support structure by attaching the rear surface of the base member to the support structure. In a second embodiment of the rack, the two engagement members are attached to one another by a centrally located substantially rectangular base member.

In the combustion of waste mineral-bearing liquid streams, an improved type of construction for the combustion chamber, for the combustion of waste mineral-bearing liquid streams which permits continuous removal of solid particulate waste. An annular water channel is fitted inside of the outer shell of the combustion chamber at the bottom. The bottom of the chamber is closed off with a funnel-shaped, inverted conical floor, having a drain outlet at its center. An opening is provided in the side of the combustion chamber just above the bottom, for the exit of downflowing products of combustion. Water is supplied to the annular channel and flows through a longitudinal gap in the inner wall, to fall onto the funnel-shaped floor plate, to wash down all of the particulate matter that collects on the bottom plate, into the drain. Thus, the waste is removed as it is formed. The refractory lining of the chamber is shaped with an inwardly-directed flange to permit the flow of molten material down the refractory surface onto the funnel-shaped floor plate and to protect the water channel from direct heating by the flame in the cumbustion chamber.

An improved fuel oil atomizer which comprises a burner tube through which fuel oil is supplied under selected pressure, and a coaxial surrounding steam tube providing an annular space therebetween, the flow of steam being under greater pressure than the oil pressure. A burner head is joined to the burner oil tube through an orifice of selected diameter. The burner head has a long axial bore of constant selected diameter, which leads to the burner tip, which has a plurality of tip ports. There are a number of transverse ports between the annular steam path and the central bore, so that the steam can flow under pressure into the central bore of the burner head to mix thoroughly with the pressurized oil flowing from the orifice. Two factors are important in the construction of the burner head, namely that the central bore must be of constant diameter from the point where the steam and oil mix, outwardly toward the burner tip ports. Secondly, the total cross-sectional area of the tip ports must be less than the cross-sectional area of the central bore.

Fuel oil atomizer

An apparatus for immediate ignition of waste gases and their smokeless burning which is built into a cylindrical stack, for the flow of waste gases. Near the top of the stack, there is positioned, coaxially, a steam-air pipe for supplying a mixture of steam and air. The steam and air are introduced into the pipe, by means of radial tubes, connected to a circular manifold on the outside of the stack. A circular cover plate or baffle over the steam-air pipe is supported by a plurality of broad strips equally spaced circumferentially, around the periphery of the steam-air pipe. There are a plurality of radial support arms between the stack and the steam-air pipe. These can be made from angle iron of sufficient width, the purpose being to deflect upwardly flow of the annular column of gas, to break it into a plurality of spaced circular segments of gas, the space above the arms protects a stable flame, for instant reignition of the mixture of gas, air and steam.

Immediate ignition smokeless burning of waste gases

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.

Low NOX burner

A burner assembly for the smokeless flare burning of low calorific value gases, or diluted hydrocarbon gases, which comprises a plurality of separate burner heads arranged in a horizontal array, each of the burner heads being mounted on top of a vertical pipe through which the low calorific gases are supplied. A plurality of hollow radial arms are inserted into the wall of the head, arranged in equally-spaced array, each of the arms having a plurality of ports in the top surfaces, near the ends of the arms. These ports are of selected size and selected angle of their axes, which are tilted inwardly towards the central axis of the burner heads. Additionally, there is between each pair of arms at least one port drilled downwardly from the inside of the burner head, at a selected angle, so that jets of gas will impinge downwardly on an annular plate positioned beneath the arms, to close off the vertical flow to the space between the arms. The arms are surrounded by a shallow cylindrical wall which is perforated in a selected uniform pattern over its entire surface. Over each of the arms is a cylindrical tube against which the gas jets, which can be sonic, impinge, so that the jets are diffused throughout the entire volume between the arms and above the arms. Air diffuses inwardly through the surrounding perforated wall to mix quietly with the gas so as to maintain a continuous combustion, with sufficient air to prevent the formation of smoke.

A burner-stack-furnace system comprising a stack of selected diameter and height, which is supported on a circular base ring, which is, itself, supported on a plurality of circularly positioned upright columns. The columns are supported on grade and are spaced equally circumferentially. The furnace or combustion section of the system is of the same diameter as the stack, and has a plurality of re-entrant vertical channels in its outer wall, spaced to surround each of the columns, with a selected air space between them. The combustion section thus hangs partly within the circle of the columns or piers, and partly between the piers. A shallow excavation is made below grade within and between the columns, and the combustion section extends downwardly into the excavation, which is deep enough that the bottom edge of the wall is above the base of the excavation. The combustion section is open on the bottom, but is filled with a porous fill of heat-resisting material, to a selected level. One or a plurality of circumferentially spaced openings in the wall of the combustion section are provided for combustion air and for gaseous or liquid fuel burners. In addition to the pipes which supply fuel to the burners, there are other pipes which supply either water or steam. The water is supplied through an atomizing nozzle, so that the droplets flow directly into the path of the fuel and into the flame.

In a flare system for waste gases, apparatus is provided for controlling the flow of purge gas into the flare gas line, as required, and not on a continuing basis. Sensor means are provided for detecting a change in temperature in the flare gas line, and means are provided for controlling the flow of purge gas whenever the temperature in the flare gas line changes to a lower value. No purge gas flow is required when the temperature is constant or when the temperature is rising.

Control system for purge gas to flare

A low NOx burner for a furnace operating under natural draft in which primary and secondary combustion air are provided to a first burning zone, in which either or both liquid and gaseous fuel can be used. Less than stoichiometric air is supplied in the primary burning zone and tertiary combustion air is supplied in a second combustion zone downstream from the first combustion zone. The total air supply is over the stoichiometric requirement. Air control means is provided so that a fixed ratio of primary-secondary air/tertiary air is provided for all burning and fuel rate conditions, so as to maintain the less than stoichiometric air supply to the first combustion zone. In addition, water atomization is provided upstream of the first burning zone to provide a burning chemistry which favors the reduction of NOx in the first burning zone.

A multi-fuel gas burner using preheated forced draft air, comprising a cylindrical inner burner tube, supported by the wall of a furnace, and inserted into an opening in said wall, and including means to inject through the upstream end combustion air preheated to a selected temperature, and compressed to a selected pressure. The downstream end of the inner burner tube closed, and a plurality of longitudinal slots, circumferentially spaced, in the wall of the tube at the closed end. Means to inject rich fuel gas up to 3,500 btu/cu feet under selected pressure into the inner burner tube along its axis. An outer burner tube axially surrounding said inner burner tube and forming an annular passage therebetween. Means to pass low pressure, lean, combustible gas of as low as 50 btu/cu feet down said annular passage and outwardly through a circumferential slot at the end of said outer burner tube inside the furnace. The hot combustion air and rich gas flowing through the inner burner tube and radially outwardly and rearwardly through the plurality of slots, flow against and mix with the lean gas flowing outwardly through the circumferential slot, and burn against the surface of a tile, having a central opening, through which the burner is inserted into the furnace.

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. A second air plenum is provided coaxial with and surrounding the first combustion zone and tertiary air is supplied tangentially to this air plenum so that the tertiary air will flow in a helical swirling motion along the outside of the first combustion chamber, around the downstream end of the combustion chamber and will meet and mix with the hot products of combustion from the first combustion chamber. Control of the shape of the flame is provided by controlling the relative directions of tangential flow of air in the two plena.

Burner for reduced NOx emission and control of flame spread and length

A self-contained single structure for NOX disposal and heat recovery, comprising a burner means (12), including means to supply NOX (oxides of nitrogen) gases (146) to be reduced, primary air (130) in less-than-stoichiometric flow rate, and gaseous fuel (128) at selected flow rate. The gases flow into a first reducing section (114), in which the fuel is burned in a reducing atmosphere, and the NOX gases are reduced. Fire tubes (124) carrying water or steam are positioned to receive heat from the burning gases. At the outlet of the reducing section precooled stack gases (135) are injected (137) into the flame so as to cool the hot products of combustion. The direction of flow of hot gases is turned to 90.degree. (164) in a second section. At the end of the second section the direction of flow is turned 90.degree. so as to be counter to the first direction in a third or oxidizing section (182) to which secondary air is added (172) and a fourth or boiler section (124) accepts the hot gases from the oxidizing section to recover the waste heat.

Disposal of oxides of nitrogen and heat recovery in a single

A burner system for gaseous or liquid fuels adapted for insertion through a circular tile opening in a furnace wall, comprising a burner tube for alternate supply of gaseous or liquid fuel. The burner tube is coaxial with, and inserted into said circular opening. A first stationary annular vane assembly comprises a plurality of symmetrically-placed tangentially-directed vanes enclosing a cylindrical open chamber coaxial with and upstream of said burner means. A second movable assembly of radial vanes is adapted to slide axially about the burner tube and to be moved from a first position where it is entirely outside of the chamber space, inwardly to a second position, where it is entirely inserted into the chamber space, and inside of the first annular vane assembly. Means are provided for flowing combustion air at selected pressure through the tangential vanes and into the chamber space. When the second vane assembly is moved to its first position, the tangential vanes provide a swirling helical flow of air into and axially along the chamber space, and into the downstream of the burners, providing a swirling flame. When the movable vane assembly is in its second position, inside of the chamber volume, then the tangentially-directed air flowing through the first vane assembly flows into the second vane assembly with its radial vanes. This completely cuts off the helical flow, and causes only axial flow of air past the burners and into the flame zone.

An apparatus for reducing hydrocarbon fuel requirements for Haber Ammonia Synthesis by the supply of selected gases to the second reformer of such system, comprising a first cylindrical conduit, a second smaller coaxial cylinder inside of the first conduit, forming a first annular space therebetween, the downstream end of said second conduit closed, and a plurality of circumferentially-spaced orifices in the wall of said conduit upstream of the closed end. Means to supply air at selected pressure P1, temperature and flow rate to the first annular space, means to supply at least methane at a pressure P2 greater than P1, to said second conduit, so that the concentration of methane in the air will be less than the lower explosive limit, and means to shield the jets of gas from the orifices in the second conduit, as they flow radially outwardly across the annular space. Means are also provided for adding steam in selected ratio with the methane prior to flow into the second conduit, whereby air, methane and steam are mixed together prior to flow into the second Haber reformer.
