Description

Oct. 14, 1969 I E. BARRIE 3, 02,
RADIANT GAS BURNER Filed Oct. 18. 1967 finiin i I III" II I United States Patent Tee RADIANT GAS BURNER Eric Barrie, 25 Bunarba Road, Gymea, New South Wales, Australia Filed Oct. 18, 1967, Ser. No. 676,281 Claims priority, application Australia, Oct. 21, 1966, 12,926/66 Int. Cl. F2311 13/14 US. Cl. 431-329 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates to improvements in gas burners particularly of the type used for grilling food. With these types of burners it is desirable to design the shape of the burner so that an unnecessary amount of heat will not be concentrated in the centre portion of such burner. This problem arises because the burner is approximately 100 square inches in area and a considerable quantity of heat is generated towards the centre of such burner which can lead to uneven grilling.
In one type of griller burner now in use the central portion of the burner is blanked off and the air/ gas mixture is preferentially admitted to the marginal portion of the burner. This arrangement causes incomplete secondary combustion and also localises the escape path of the combustion gases and may cause interference with other adjacent cooking operations.
Accordingly, the object of the present invention is to provide a gas burner of the grilling type which has reasonably even heat output over the whole area of the burner.
In accordance with the present invention this is provided a gas burner of the griller type comprising first and second shell members joined together around their perimeters, an aperture extending through both shell members and the portions of the shell members thereabout being joined together to form two compartments in the burner, an air/ gas inlet to the burner, each compartment having in the second shell member an opening covered by a refractory member so that the air/ gas mixture entering the burner when ignited after passing through the compartments burns on the surface of the refractory member and at least some of the products of combustion pass up through the aperture in the burner.
The invention is described by Way of example with reference to the accompanying drawings in which:
FIGURE 1 is a partially cut away plan view of the burner of the invention, and
FIGURE 2 is a partially sectioned front elevation of the burner of FIGURE 1.
In a preferred construction the burner comprises substantially flat first and second shell members 11 and 12 having marginal peripheral flange portions 13 and 14 so that one shell member may be secured to the other around such flange portions, for example, by means of a lock seam joint 15. A central aperture 16 is provided in each shell member 11 and 12 and each has a flange portion 17 and 18 thereabout so that the shell portions 11 and 3,472,602 Patented Oct. 14, 1969 12 may be also joined together by a lock seam joint 19 thereby around the aperture in the completed burner shell. The thickness of the burner shell as assembled may increase from the perimeter 15 towards the aperture 16 and in the preferred construction being described the aperture forms two compartments 29 and 21, one on each side of the aperture and inter-connected to each other around the ends of the aperture 16 which is elongated in plan.
At one side of the burner adjacent an end of the aperture there is provided a flared out open inlet portion 22 to which is mounted the usual air mixing and connecting devices 23 required in a gas burner. As the gas air mixture passes into the burner it is deflected into the compartments 20 and 21 by a baflle 30 which, in side elevation, that is, a direction parallel to but transverse to the longitudinal axis of the aperture, is V shaped and extends from one shell member 11 to the other shell member 12 of the burner with the apex closest the wall of the aperture 16.
'Each compartment 20 and 21 is provided with an opening or gas outlet in the second shell member 12 which is of-such size as to extend towards the marginal portions 14 and the aperture 16. Each gas opening has a marginal flange 24 and 25 for mounting thereon a gauze or other refractory member 26 and 27 so that the gas air mixture after passing through the compartments 20 and 21 of the burner passes through such refractory or gauze 26 and 27 and is ignited on the outer surface thereof. The flanges 24 and 25 for mounting the refractory member vary in extent because of the varying thickness of the burner.
The burner may be provided with mounting flanges 28 and 29 so that it can be readily mounted, refractory member downwards in the griller assembly.
I claim:
1. A gas burner of the griller type comprising first and second shell members each having an elongated aperture and having marginal flanges around the perimeter of the shell and around the aperture, the marginal flanges around each shell member being secured together and the marginal flanges around the apertures being joined together with the flanges being sized so the spacing between the shell members increases from the perimeter towards the aperture, a compartment on each side of the elongated aperture, said compartments being joined at each end of the aperture, an air/gas inlet to the burner in general alignment with the aperture at one end of the aperture whereby incoming air/ gas mixture flows laterally to reach the two compartments, each compartment having in the second shell member an opening surrounded by a flange, a refractory member secured to the latter flange so that the air/gas mixture entering the burner passes into the compartments and burns on the surface of the refractory members and some of the products of combustion pass up through the aperture in the burner.
