Appl. No.:

5/779595

Inventors:

John S. Zink - Tulsa OK
Robert D. Reed - Tulsa OK
Robert E. Schwartz - Tulsa OK

Assignee:

John Zink Company - Tulsa OK

International Classification:

F23D 1500

US Classification:

431202

Abstract:

Apparatus for the smokeless combustion of gases, supplied at substantial pressure, such that they will aspirate the required combustion air when discharged to atmospheric pressure. The apparatus comprises a plurality of spaced apart burner assemblies, each of which has a plurality of orifices arranged in a circular symmetrical pattern. Each burner assembly comprises a vertical tube supplying gas, with a plurality of short substantially radial arms, each of which has a plurality of orifices in its top surface. The arms themselves are tilted upwardly at a selected angle to the horizontal so that the orifices that are perpendicular to the arms will provide gas jets which will intersect each other along the axis of the assembly. In another embodiment, the top surface of the arms form a plane fingered plate of substantial thickness. The orifices are drilled at a selected angle toward the axis, in the top surface of the plate.

International Classification:

F23J 1500

US Classification:

431 9

Abstract:

An improved burner for both liquid and gaseous fuels in which the combustion air is divided into at least two parts, comprising primary and secondary air. The primary air, which is insufficient to completely burn the fuel, creates a flame zone in which there is a deficiency of air, which produces quantities of carbon monoxide and hydrogen. The combustion products are recirculated, cooled and re-entered into the combustion zone in the region of the fuel and primary air entry, resulting in a reduction in the oxides of nitrogen. The secondary air, in quantities greater than the primary air, is introduced into a second combustion zone downstream of the first combustion zone. In the second combustion zone the deficiency in air is made up by the secondary air so that complete combustion can be carried out. If desired, a third quantity of air can be introduced still farther downstream in the flame zone.

International Classification:

F23d 1320

US Classification:

431202

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.

International Classification:

F23D 1312

US Classification:

431348

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.

International Classification:

F23L 700

US Classification:

431202

Abstract:

Apparatus for the injection of steam for the smokeless combustion of waste gases, comprising an annular chamber of substantially the same inner diameter as the top of the flare stack, the chamber mounted on top of the flare stack and extending outwardly a selected radial distance, and vertically a selected height above the top of the flare stack. Steam is supplied to this annular chamber. A plurality of circumferentially spaced pipes are provided in the top of the annular chamber and are deflected outwardly in radial planes at selected angles. There are a plurality of inwardly and upwardly directed orifices for the injection of steam into the flame of the burning gases above the top of the annular chamber as well as to the gases prior to emergence for burning. Additionally, there may be a plurality of circumferentially spaced radial pipes inserted through the inner wall of the annular chamber in a horizontal plane a selected distance down from the top of the chamber. These pipes extend toward the axis of the stack and contain a plurality of orifices in the top quadrant of the pipes for the injection of steam into the rising flow of gas at a selected distance upstream of the plane of burning.

US Classification:

98 58

Abstract:

An improved construction for an upwardly extending flare stack for the emergency venting to the atmosphere of large quantities of combustible gases, such improvement being for the purpose of preventing the inflow, and upstream flow of air, into the flare stack, comprising an annular obstruction means attached to the inner surface of the flare stack a short distance upstream of the downstream end of the stack.

International Classification:

B36B 5900

US Classification:

114222

Abstract:

The device of the present invention, an enclosure for partially submerged boat keels, rudders and lower units, is a box-like structure constructed to enclose those described parts extending downwards from the hull of a boat when the boat is lifted from the water on a hoist in such a manner as to prevent direct contact with the water. The device is positioned about the submerged portion of the keel, rudder or lower unit and then emptied of water, resulting in flotation of the upper portions of the enclosure to a level above the surrounding waterline. By thus preventing continuous direct contact with water during periods of storage, the adverse effects of bottom growth and gelcoat blistering are reduced or eliminated, thus enhancing performance underway and reducing maintenance.

Abstract:

Apparatus for vaporization of liquids having a boiling point lower than that of water, comprising a vessel having at least three narrow planar plena, contiguous to each other, so that there is a single metal wall between each adjacent pair of plena. Gaseous fuel and air is supplied to the first plenum to provide a downflowing flame and hot products of combustion which, at the bottom of the first plenum, pass through the wall into the second plenum, which is filled with water. The hot gases and water rise rapidly in the second plenum and the water flows over the intervening wall into the third plenum, which is also filled with water, which moves downwardly and back under the wall separating the second and third plena, and again rises in the second plenum. A vertical array of horizontal pipes is arranged in the third plenum, through which the liquid to be vaporized is flowed. Means are provided at the base of the first plenum, to distribute the flow of hot gases substantially uniformly over the cross-section, to provide more rapid and uniform heat transfer from the hot gases to the liquid.
