    Abstract: A burner system for burning gaseous or liquid fuel, comprises a primary burner system, which includes a liquid burner tube closed at one end and provided with a plurality of primary combustion ports symmetrically arranged to provide a plurality of jets forming a conical sheet of particles of fuel. Surrounding the liquid burner is a gas burner tube, which comprises the annular space between two coaxial tubes closed at the end, and including therein a plurality of primary combustion ports arranged symmetrically to provide jets arranged on the surface of a cone. Combustion air is drawn into the space around the gas burner tube, to supply combustion air for the liquid and/or gaseous fuel. Upstream of the primary combustion ports is a secondary burner which is circular in configuration, and surrounds, and is spaced from the gas burner tube. A limited quantity of gaseous fuel is supplied in the form of a circumferentially directed jet in the lee of an annular plate. The combustion air flows adjacent the secondary burner and the products of combustion of the gas in the secondary burner, flows with the air into the combustion zone of the primary burner, where the carbon dioxide and water serve to reduce any NOx that may be present in the combustion zone of the primary burner.

    Abstract: An improved flare stack for the smokeless burning of smoke prone fuel gases, comprising a cylindrical flare stack, an inner cylindrical conduit which is closed at its bottom end and positioned with its top at substantially the same elevation as the top of the flare stack. The flow of the smoke-prone fuel gas up the stack is diverted into the annular space between the inner conduit and the flare stack, providing an annular flow of fuel gas. Smoke suppressant, such as a mixture of steam and air, is conducted into the inner conduit and vertically upwardly to the top thereof from which it can either continue unaltered flow direction or it can be diverted outwardly and upwardly into the inner wall of the annular flow of gas, to provide quick and intimate mixing of the smoke suppressant with the fuel gas. Additionally, smoke suppressant can be injected inwardly into the outer wall of the annular flow of fuel gas, to provide additional intimate mixing of smoke suppressant, to provide smoke-free combustion of the fuel gases.

    Abstract: Hazardous inversion of ambient air into a waste gas elevated flare stack is prevented by the controlled injection of a purge gas into the bottom of the stack. Upward or downward flow of gases in the stack deflects a small horizontal, high velocity stream of gas relative to opposite tubes capable of sensing the impact energy relative to differential pressure detection devices. The devices thus send a signal to control the quantity of purge gas input as a function of the deflection of the stream.

    Abstract: A noiseless premix burner comprising a cylindrical housing which is attached to the outer covering of the furnace wall, and closed at its opposite end by a closure plate which supports a concentric burner tube which extends from the closure plate through an opening in the furnace wall to the interior of the furnace. A gas fuel line is inserted along the axis of the burner tube. Pressurized fuel gas flows through an orifice in the fuel line in an expanding flow. The proximal end of the burner tube has a venturi type throat construction. The annular space between the burner tube and the cylindrical housing comprises two plenums, one adjacent the outer wall of the furnace supplying secondary air, which passes into the furnace through a narrow annular gap between the burner tube and the furnace lining. The second plenum provides primary air to the burner tube at the position of the fuel nozzle, where it mixes turbulently with the inflowing high velocity gas stream, to provide a fuel-air mixture which passes down the burner tube. The axial outlet of the burner tube inside the furnace is closed and there are a plurality of longitudinal slots spaced circumferentially around the burner tube through which the gas-air mixture moves radially into the furnace impinging on tile which surrounds the burner tube.

    Abstract: A vertically fired means for the combustion of waste gases in a noise-proof manner having a vertically oriented cylindrical furnace with burner insertion into the bottom of the furnace, which is raised a selected distance above the surface grade. The inlet air opening at the bottom of the furnace is of a cross section area less than a selected fraction of the cross section area of the combustion zone. A cylindrical windshield encircling the bottom of the furnace provides limited access of air to the area below the inlet air opening at the bottom of the furnace to suitably isolate wind flow from the inlet air opening. The cross-sectional area for air flow due to limited access is at least equal to a selected fractional area of the furnace, which is the inlet air opening. Suitable isolation of air flow energies from the inlet air opening requires the limited access area to be no greater than 2.5 times the air inlet area. The inlet air opening is preferably not more than 85% of the furnace area. One or more burners are provided from suitable manifolds so that the flame resulting from the combustion of the waste gases issues preferably in the inlet air opening to the furnace. The inlet air opening area is preferably in the range of 0.2 to 0.85 of the cross section area of the furnace.

    Abstract: 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.
