Definitions
- the burner according to the invention comprises a bundle of tubular elements each open at each of its ends for the supply therethrough of combustion air for said burner, each of said tubular elements being provided at one end with a head portion having an external crosssection such that when said bundle of tubular elements are bunched together with their head portions in contact with each other fuel orifices are formed between said head portions for fuel supplied to said burner.
- the burner according to the invention comprises a housing defining a fuel chamber, an inlet for fuel opening into said chamber, a bundle of tubular elements mounted in said chamber in laterally spaced substantially parallel relationship with each end of each of said tubular elements open to atmosphere, each of said tubular elements being provided at one end with an enlarged head portion having an external cross-section such that when said bundle of tubular elements are bunched together in said chamber with their head portions in contact with each other fuel outlet orifices are formed between said head portions.
- the invention also includes a tubular element for use with a burner according to the invention, said tubular element comprising at one end a head portion of enlarged non-circular external cross-section, said tubular element preferably also having a portion whose outer surface tapers inwardly for a short distance from said head portion, and an outwardly flared inner surface at said head portion.
- FIG. 1 is a plan view of a burner according to the invention
- FIG. 2 is a section on the line II--II of FIG. 1;
- FIG. 3 is an inverted plan view of the burner according to FIG. 1;
- FIG. 4 is an enlarged view of a detail
- FIG. 5 is an axial sectional view on the line V-V of FIG. 6 of one of the tubular elements used with the burner;
- FIGS. 6, 7 and 8 are plan views of tubular elements having enlarged head portions of dilfere'nt cross-sectional shapes.
- FIG. 9 is a side elevation of the tubular element according to FIG. 8.
- the burner according to the invention comprises a housing 10, defining a fuel chamber 11, a fuel inlet 12 opening into said chamber and having a connecting piece 12a for connecting a pipe line to a source of fuel supply, and a bundle of tubular elements 13 bunched together in said chamber in laterally spaced substantially parallel relationship.
- the base or bottom wall 14 of the housing 10 is provided with a plurality of circular apertures (see FIG. 3) for receiving the lower circular non-headed ends of the tubular elements 13 and the upper wall or top plate 15 of said housing is provided with a hexagonal opening 16 in which enlarged head portions 17 (hereinafter more fully described) of the bunched tubular elements are located in contact with each other with the head portions of the outer ring of tubular elements in close contact with the edges defining said hexagonal opening.
- said tubular elements are open to the atmosphere at each of their ends.
- the aperatures in the base or lower wall 14 of the housing 10 are slightly inwardly tapered, as shown more clearly in FIG. 2, and the lower cylindrical non-headed ends of said tubular elements when inserted in said apertures are splayed out and bonded to the walls of said apertures, for example with an epoxy resin, so as to ensure a fiuid tight joint.
- each of the tubular elements 13 is provided with a head portion 17 of enlarged non-circular external cross-section.
- said head portion is of hexagonal cross-section and the side surfaces of the hexagon are of dished or concave configuration as shown in FIG. 6.
- the edges defining the hexagonal opening 16 in the top or upper wall 15 of the burner are corrugated or provided with curved or convex projections 16a which fit closely in the concave sides of adjacent head portions and are bonded to said head portions with, for example, an epoxy resin to form a fluid-tight joint.
- gas or other fuel is fed into chamber 11, circulates around the tubular elements 13 and passes out of said chamber through the burner orifices 18 and when the gas issuing from said orifices is ignited the burning gas or other fuel will cause combustion air to be drawn through said tubular element by induction to mix with the issuing gas or other fuel to produce the required flame.
- each of said tubular elements tapers inwardly for a short distance from said head portion 17, as indicated at 19 in FIG. 5, so that when a bundle of said tubular elements are bunched together, as shown in FIG. 1, the passage between said tubular elements have a reduced cross-sectional area adjacent to the inlet of burner orifices 18 as indicated at 20 in FIG. 2.
- a turbulence is created at the inlet to said orifice and thereby ensures a uniform distribution of fuel over the entire area of the burner plate and therefore an equal and constant flow of fuel through each of said orifices.
- each of said tubular elements preferably flares outwardly at said head portion as indicated at 23 in FIG. 5.
- the tubular elements 13, an example of which is illustrated in FIG. 5, have the advantage that they can be manufactured relatively cheaply by cold forming, for example by impact extrusion.
- a tubular element having an enlarged hexagonal head 17 with dished or concave sides Whilst a tubular element having an enlarged hexagonal head 17 with dished or concave sides, as in the particular embodiment above described, is at present believed to be the most suitable form, the enlarged head may have other non-circular forms and in order to provide the necessary gap between adjacent heads of said tubular member, when bunched together, to form the fuel orifices 18 a hexagonal headed tubular element need not necessarily be provided with dished or concave sides as shown in FIG. 6, but each of the side surfaces of the hexagon may be provided with an axially extending rib 21 adjacent to the corners of said surfaces (FIGS. 8 and 9-) or the corners defined by adjacent side surfaces of the hexagon are each provided with a rib-like portion or protuberance 22 (FIG. 7).
- a burner for burning fluid fuel comprising a bundle of tubular elements each open at each of its ends for the supply therethrough of combustion air for said burner, each of said tubular elements being provided at one end with a head portion having an external cross-section which provides a plurality of spacer means such that when said bundle of tubular elements are bunched together the spacer means on each head portion contacts each adjacent head portion to provide fuel orifices between said head portions.
- a burner for burning fluid fuel comprising a housing defining a fuel chamber, an inlet for fuel opening into said chamber, a bundle of tubular elements mounted in said chamber in laterally spaced substantially parallel relationship with each end of each of said tubular elements open to atmosphere, each of said tubular elements being provided at one end with an enlarged head portion having an external cross-section which provides a plurality of spacer means such that when said bundle of tubular elements are bunched together in said chamber the spacer means on each head portion contacts each adjacent head portion to provide fuel orifices between said head portions.
- a burner for burning gaseous fuel comprising a housing defining a fuel chamber, an inlet for fuel opening into said chamber, a bundle of tubular elements mounted in said chamber in laterally spaced substantially parallel relationship with each end of each of said tubular elements open to atmosphere, each of said tubular elements being provided with a non-headed end at one end and provided at the opposite end thereof with an enlarged head portion having a hexagonal external cross-section with the side surfaces of the hexagon concave in configuration so that when said bundle of tubular elements are bunched together in said chamber with a part of their head portions in contact with each other fuel outlet orifices are formed between said head portions.
- each of said tubular elements is hexagonal in cross-section and the surfaces of the sides of the hexagon are each provided with an axially extending rib forming said spacer means, said rib being located adjacent to the corners of the hexagon.
- each of said tubular elements is hexagonal in cross-section and the corners defined by adjacent sides of the hexagon are each provided with an outwardly extending rib-like portion forming said spacer means.
- each of said tubular elements tapers inwardly for a short distance from said head portion and the inner surface flares outwardly at said head portion.
- each of said tubular elements tapers inwardly for a short distance from said head portion and the inner surface of said tubular element -flares outwardly at said head portion.
- each of said elements is provided with a, hexagonal head portion including a plurality of spacer means, the spacer means on each head portion contacts each adjacent head portion to provide said fuel orifices and each of said tubular elements is provided with an outwardly flared inner surface at said head portion and an inwardly tapered outer surface adjacent to said head portion.
