COMBINATION OIL. AND/OR GASEOUS FUEL BURNER Filed June 13, 1962 2 Sheets-Sheet 2 FIC-3.3

INVENTORSZ ROBERT D. REED JOHN SMITH ZlNK ATTORNEYS Unted States Patent O 3,174,527 COMBINATION OIL AND/ R GASEOUS FUEL BURNER Robert D. Reed and .lohn Smith Zink, Tulsa, Okla.,

assignors to John Zink Company, Tulsa, Okla., a corporation of Delaware Filed June 13, 1962, Ser. No. 202,254 4 Claims. (Cl. 158-11) This invention relates to a burner construction and more particularly to a combination liquid and/or gas fuel burner for use in producing high temperatures.

A primary object of this invention is to provide a burner construction capable of burning either gaseous and/ or liquid fuels to produce a relatively thin, at, substantially triangular flame shape. Such a llame occurs from the burning of either fuel or with Iboth fuels tired simultaneously.

Another object of this invention is to provide a burner construction capable of creating a relatively flat, thin and substantially triangular llame which can be readily manufactured and is economical to construct and operate.

These and other objects of this invention will become more apparent upon further reading of the specification and claims when taken in conjunction with the following illustrations, of which:

FIGURE 1 is a side elevation View partly in crosssection depicting the burner construction of this invention and the result-ant flame therefrom.

FIGURE 2 is a top elevational view view, partly in cross-section depicting the burner construction of this invention and the resultant flame.

FIGURE 3 is a frontal View taken along the line 3-3 of FIGURE 2.

FIGURE 4 is a sectional view taken along the line 4-4 of FIGURE 2.

FIGURE 5 is a sectional view taken along the line 5-5 of FIGURE 2.

FIGURE 6 is a sectional view taken along the line 6 6 of FIGURE 2.

Briefly, this invention is directed to a burner block construction having an opening or port which is defined herein as being substantially frusto-conical-pyramid in its peripheral shape. That is, a substantially rectangular base with rounded corners defines the -frontal opening which converges rearwardly to a substantially circular opening. A typical liquid fuel injection system is axially located adjacent the circular opening and directed toward the frontal opening. The injection system includes means to mix the liquid fuel with combustion supporting gas such as air.

A gaseous fuel-air mixture is separately injected and ignited and forced to flow through upper and lower channels. Each of the upper and lower channels specifically include a horizontal portion and an angular portion, the latter of which terminates at junction with the opening delined by the frusto-conical-pyramid walls. An input gas-air mixture is admitted into each channel and flows along the horizontal portion until diverted by the angular portion, which is, typically, a refractory surface. The issuing gases substantially intersect with the liquid yfuelair mixture, above and below, in the burner opening to form a resultant flame of relatively flat, thin and of substantially triangular shape extending substantially forward of the opening. At best, the flame will form a shape substantially identical to the burner opening, i.e., frustoconical-pyramidic.

Description Referring now to the drawings in detail. The numerals 1li and 12 represent a furnace wall and floor con- 3,174,527 Patented Mar. 23, 1965 ice struction within which the burner block 14 of this invention is typically installed. It is to be understood that this is given by way of example only as the burner block 14 is adaptable to other types of construction where high temperature is required. VThe burner block 14 is molded or constructed of a suitable refractory material. A refractory material which is capable of becoming incandescent to assist the combustion of the gaseous and/ or liquid fuel-air mixtures is preferred.

The frusto-conical-pyramid opening in the burner block 14 tapers inward from forward face 16 rearwardly to opening 18 to form burner cham-ber 19. As shown in the drawing, the forward opening 16 is relatively rectangular in shape with rounded ends while the rear opening 18 is circular. The maximum vertical width of the opening is substantially epual to the diameter of rear opening 18.

Suitably attached to the rear face of the burner block 14 and/ or furnace wall 10 or floor 12 is support mounting plate 20 to which the stator portion 22 of a liquid fuel or oil register is axially located with respect to the burner chamber. Rotor 24 is suitably attached to the stator and rotatable therewith to control the primary air supply to the oil register. A concentric hub 26 is adapted to receive the liquid fuel guide tube 28 which is axially movable therein. A liquid fuel manifold 3l) is adapted to receive, singularly or simultaneously, oil from inlet 32 and/or steam at inlet 34. Steam is used to atomize the oil and assist in the combustion process. The combined oil plus steam passes through conduit 36 into nozzle 38 where a multiplicity of horizontal openings 39 are adapted to fan vaporized liquid fuel, such as oil, into the opening within the burner block. The combined configuration of the burner block opening and the horizontally aligned ports 39 at the tip of the oil atomizing gun initially assists to form the desired llame shape, i.e., fiat, thin, substantially triangular or fan shape.

Adjustably attached to the support mounting plate 20 are upper and lower air control doors 40 and 40' suitably arranged with respect to upper and lower gaseous fuel inlet heads 42 and 42 which are rearwardly attached to gaseous fuel supply conduits 44. The gaseous fuel, such as methane, or liquified petroleum gas (LRG.) such as butane or propane, passes through a multiplicity of horizontal ports 43 and 43 into mixing and combustion channels 48 and 48. The gaseous fuel passing through ports 43 and 43 mixes with controlled amounts of air entering through doors 4t] and 40. The upper and lower channels 48 and 48' are of substantially constant rectangular crosssection and extend horizontally a short distance and thence angularly until junction 52 with the opening 19, slightly rearwardly of but substantially adjacent the forward opening 16. Channels 48 and 48 intersect with the chamber at an angle more than with respect to forward open ing 16. Upper and lower surfaces 50 and 50' respectively serve to deflect and direct the expanding and burning gasair mixture into the burner opening. The upper and lower combustion streams passing through channels 48 and 48 intersect in the burner chamber, the resultant force of which produces forward ow and a flat, thin flame 60 (FIGURE 1), substantially triangular or trapezoidal in shape (FIGURE 2).

Surfaces S0 and 50 being of a refractory material, become heated by the burning gas-air mixture within channels 48 and 48. The heated surface of the refractory becomes incandescent or a heat source to accelerate the burning of the combustible gaseous fuel-air mixture.

A tertiary air Ysupply is admitted through opening 54 which extends from the forward burner block face to the rearward face on support plate 20 where the air supply is controlled by a draft or shutter apparatus 56. The tertiary air supply provides not only a cooling medium for the re- 3 fractory surface, but also an aid to complete combustion of the fuel. The air passing outward from opening 54 into the forward flame area is drawn into the ame because of its relatively high velocity.

The burner chamber 19 is designed such that when liquid fuel-air mixtures are red and burned, there is little or no contact of partially burned oilwith the peripheral surface, hence coking and carbonizing of the surface is eliminated.

The preceding description makes it apparent that the construction is susceptible to some modification. For example, although the construction has been shown for a typical horizontal installation, ie., the flat, thin, trapezoidal shaped flame is horizontal, it is to be understood that the burner block may-be so rotated as to form a substantially vertical flame. Accordingly, these changes and others can be made without departing from the spirit and scope of this invention as set forth in the appended claims.

What is claimed:

1. A combination burner for combustible mixtures of gaseous and/ or liquid hydrocarbon fuels comprising the combination of:

a support block having substantially parallel forward and rear faces,

a burner chamber in said block peripherally transitioned from a substantially circular opening at said rear face to an opening at lsaid forward face of vertical width substantially equal to the diameter of said circular opening and a horizontal length greater than said diameter,

4;- means to inject a combustible fuel mixture axially of said chamber toward said opening at said forward face, and means to inject a combustible fuel mixture into each of said upper and lower channels to cause a resultant ame of a relatively at, thin and substantially triangular shape.

2. A combination burner as dened in claim l wherein said upper and lower channels extend substantially across the horizontal length of said chamber walls where said channels terminate into said chamber.

3. A combination burner as defined in claim 1 wherein said upper and lower channels angularly intersect said chamber at an obtuse angle toward said forward face.

4. A combination burner as defined in claim 1 wherein an auxiliary air supply conduit extends from said rear face to said forward face-parallel to the horizontal axis of said chamber.
