- Att0rneyMason, Fenwick & Lawrence [5 7 ABSTRACT A gas burner which provides between the exit orifices and the ignition level a free path for gas jets emanating from the orifices to ensure sufficient aeration of the gas jets.
- the burner comprises a casing connectible to a gas supply and having a number of gas exit orifices provided therein.
- a distributor body Above these orifices there is provided a distributor body presenting a distribution wall inclined relative to the axes of the exit orifices and with its upper edge disposed at least approximately in the plane defined by the axis of the exit orifices. This edge forms part of a ledge whereof at least the major part is on the same side as the orifices and above the distribution wall.
- the ledge and distribution wall subtend an acute angle at said edge and the other edge of the ledge terminates in a low wall substantially perpendicular to the ledge and parallel with the edge.
- This invention relates to a gas burner of the type ensuring the mixture of air and gas by induction and diffusion produced around a jet of free gas and comprising a casing connected to a source of combustible gas, an appropriate number of gas exit orifices arranged in the casing and a distribution wall which at its upper part and opposite the exit orifices terminates in a ridge or edge, the wall being disposed above the casing with regard to the exit orifices and being inclined relative to the axes of the exit orifices.
- the gas jets are directed towards the central or median part of the distribution wall, where they entirely collapse or spread out, so that the flames ignited on the distribution wall are diverted by the wall and burn along the wall which serves as a deflector.
- the distribution wall is located very near the gas exit orifices so that the aeration of the gas jets impinging on the wall is insufficient if one uses gas other than Town gas and particularly gases rich in hydrocarbons.
- the distribution wall there is produced on the distribution wall a carbonaceous deposit which renders the flame unstable and causes poor combustion of the gas. This inconvenience can be accepted when one only uses the burner sporadically, for example, to ignite combustible solids placed on a grille above this known burner.
- the invention has for its object the mitigation or obviation of the aforesaid inconveniences and the realization of a burner of the type first-mentioned which permits the obtaining of correctly aerated and stabilized flames of compact form and presenting a sufficient impulsion to permit them to preserve their general direction whatever the inclination of the burner.
- the top ridge or edge of the distribution wall is located at least approximately in the plane defined by the axes of the exit orifices and is adjacent a ledge whereof at least the major part is located on the same side of the axes of the exit orifice and above the distribution wall, the ledge, on the one hand, forming with the distribution wall, in a plane perpendicular to the ridge or edge, an acute angle, and, on the other hand, at the side opposite the ridge or edge being limited by a wall of small height which is at least approximately perpendicular to the plane of the ledge or edge and parallel with the ridge.
- the gas-air mixture is directed to the surface of the edge or ridge and the ledge of the distribution wall by tubulences which are created at this surface.
- the tubulences overcome the speed of the jet of gas-air mixture, and when this mixture is ignited at the surface of the ledge, it burns with a stable flame which has an impulsion sufficient to burn with an elongate form substantially parallel to the plane of the ledge. As the flame itself is free on all sides, secondary air can flow thereto and ensure correct combustion without carbonization.

- FIG. 4 is a perspective view of a fourth embodiment
- FIG. 5 is a sectional view of a fifth embodiment
- FIG. 6 is a vertical sectional view on the line VI-VI of FIG. 7 through a burner particularly suitable for cooking;
- FIG. 7 is a plan view of the burner shown in FIG. 6;
- FIGS. 8 to 10 show in section and perspective modifications of the embodiments of FIGS. 1, 3 and 5, and
- FIG. 11 is a graph showing the relationship between the different parameters of constructions of a burner according to the invention.
- the burners shown in FIGS. 1 to 5 comprise a distributor body 1 associated with several gas exit orifices 2 formed in a casing 3 connected to a source of combustible gas.
- the exit orifices 2 of small diameter, for example 0.3 to 2.5 mm are formed by any appropriate means in the upper part of the casing 3, constituted for example by a screwed coupling connected through the intermediary of a feed pipe to a source of combustible gas.
- the exit orifices 2 are preferably disposed near the edge of the casing 3.
- the axis of the exit orifices 2 is, for example, parallel with the general axis of the burner and is disposed in a particular manner as will be explained later.
- the distributor body 1 is mounted, in appropriate manner, on the part of the casing 3 provided with the exit orifices 2.
- the distributor body 1 presents a distribution wall 4 inclined relative to the axis of the gas exit orifices 2 and has at the end remote from the exit orifices 2 a ridge or edge 7 followed by a ledge or shoulder 5 directed away from the plane defined by the axis of the exit orifices 2.
- the ledge or shoulder 5 terminates remote from the top ridge or edge 7 of the distribution wall 4 in a wall 6 of slight height preferably perpendicular to the plane of the ledge 5.
- the height of the wall 6 terminating the ledge 5 is substantially equal to the width or depth of the ledge 5.
- the ledge determines with the upper extremity of the inclined distribution wall 4 the sharp ridge or edge 7 located in the plane or very near the plane defined by the axes of the exit orifices 2. In other words, when the axes of the exit orifices are vertical the sharp edge 7 is located straight above the exit orifices 2.
- the angle subtended at the ridge or edge 7 between the distribution wall 4 and the ledge 5 is an acute angle.
- the inclination of the distribution wall 4 relative to the axis of the exit orifices 2 is between 5 and 30, preferably As can be seen in FIG. 1, the distributor body 1 has a second distribution wall 4a disposed symmetrically relative to the plane of symmetry of the burner. Exit orifices 2a, a ledge or shoulder 5a and a low wall 6a are equally provided in symmetrical fashion relative to the plane of symmetry of the burner.
- the functioning of the burner according to the invention is as follows: the jets 8 and 8a of pure gas leaving the exit orifices 2, 2a passes into the free air and partially strike at a small angle the upper part of the inclined distribution wall 4, 4a. There is thus assured a preliminary mixing of the ambient air and the combustible gas due to the phenomena of induction and diffusion produced around the lower zone of the gas jet; the path of the inducted air is indicated schematically in FIG. 1 by the arrows 9. Due to these phenomena there is obtained a well aerated gas jet.
- This spreading of the air-gas jet ensures the mixing and homogenization of the mixture. Moreover, this spreading facilitates the interignition of the different jets of mixture impinging on the upper part of the distribution wall 4, 40. Further, by differential braking of the different layers of jets of mixture, the gas-air mixture tends to adhere to the wall 4, 4a.
- the air-gas mixture commences to burn at the level of the ledge or shoulder 5.
- the ledge 5 modifies the spreading of the gas-air mixture by creating a zone of turbulence in which the speed of circulation of the gasair mixture due to the kinetic energy of the jets of gas is practically cancelled out.
- the flames are stabilized on the distributor body 1 and their roots are held at the level of the ledge 5 and the wall 6.
- the flames are stabilized at the surface of the ledge 5 and the wall 6 by the phenomenon of retention.
- the combustion of the air-gas mixture held at the level of the shoulder or ledge 5 creates a thermal draught directed towards the flame 10, 11 a secondary flow of air moving along the direction of the arrows 12 and bringing towards the center of the flame l0, 1 1, the air-gas mixture corresponding to the part of the gas jets elongated by the distribution wall 4, 4a.
- the current of secondary air surrounds the flame 10, 111 at the holding location (ledge 5 and wall 6) and contributes to the aeration of the flame 10, 1 1 by diffusion.
- the combustion zone is consequently stabilized at the level of the upper extremity of the distributor body 1 and initiates flames of the aerated type presenting a blue cone 10 and a plume 11.
- the air-gas mixture near the stoechiometric value initiates flames of slight volume, stable and turbulent.
- the distributor body 1 is elongate perpendicularly with a section shown as a slope.
- FIG. 2 there is shown a second embodiment of burner comprising a distributor body 1 of truncated form integral at its smaller end with a casing 3 is the form of a plinth closed at its upper face 3b and provided at its lower end with screw-threading 30 to permit its securement to a gas feed pipe.
- the annular face at the side of the smaller end of the truncated distributor body 1 is provided with a certain number of gas exit orifices 2 disposed in a circle and located directly beneath the sharp edge 7 of the larger end of the truncated distributor body 1.
- a low cylindrical element 6 which delimits at the larger end of the distributor body 1 the annular ledge or shoulder 5.
- the burner shown in FIG. 3 comprises a casing 3 in the form of a rectangular rail.
- This rail is for example, constituted by a flattened tube whereof the upper elongate surface is provided near one of its longitudinal edges with a series of exit orifices and near the other edge with a distributor body 1 formed by a metal sheet folded so as to provide, as in the preceding example, a distribution wall 4, a ledge 5, a low wall 6 and a sharp edge 7 located in the plane defined by the axes of the exit orifices 2.
- This burner can be completed by a second burner 1 which is disposed symmetrically relative to and adjacent the first (1) so that the rail faces 3, 3a provided with exit orifices 2, the distribution walls 4, 4a and the low walls 6, 6a are located opposite one another while the intermediate space 15 permits air to aerate the flames at the sides of the low walls 6, 6a.
- the ledge 5a merges with the upper extremity of the distribution wall at the rectilinear sharp edge 7a and forms with the said wall 4a an acute angle.
- the rail 3 as well as the distributor body constituted by the inclined walls 4, 4a, the ledges 5, 5a and the low walls 6, 6a parallel with the axes of the exit orifices can be provided in the form of an annulus or a coil.
- FIG. 4 there is shown a simple annular burner.
- the casing is constituted by an annular tube 3 supporting on its inner edge the hollow distributor body 1 of truncated form.
- the tube 3 is provided on its periphery with a feed pipe 13 which extends tangentially into the chamber defined by the annular tube 3 which has at its upper face, near its outer edge a series of exit orifices 2 disposed this time in a circle.
- the distributor body 1 presents an inclined distribution wall 4 constituted by a metal sheet of truncated form whereof the smaller end is integral with the annular tube 3 within the circle defined by the series of exit orifices 2.
- the inclined distribution wall 4 has an annular ledge or shoulder 5 extending radially inwards and whereof the exterior edge constitutes the sharp edge 7 at the upper extremity of the inclined distribution wall.
- the ledge 5 terminates in a low sheet metal wall 6 perpendicular to the plane of the ledge 5.
- the sharp edge 7 is located vertically above the exit orifices or move precisely in the plane defined by the axes of the exit orifices 2.
- the embodiment shown in FIG. 5 difiers from the previously described embodiments in that the axis of the exit orifices 2 is inclined relative to the plane or general axis of the burner.
- the angle of inclination between the axis of the exit orifices and the distribution wall 4 is between 5 and 30 and is preferably
- the upper and lower surfaces 3b, 3d of the top wall of the casing 3 are perpendicular to the axis of the exit orifices 2. Due to the inclination of the axes of the exit orifices 2, the burner can be conceived in a most compact manner, which is advantageous especially in installations which provide little space for mounting burners.
- the upper end of the low wall 6 inwardly of the sharp edge 7 is provided with a flange 14 which is parallel to the ledge 5 and is rectilinear or annular depending on the general form of the burner, this flange 14 protruding slightly relative to the wall 6 to overly part of the shoulder or ledge 5.
- This flange 14 has, preferably, a width and a height between a quarter and a third of the height of the wall 6.
- the general axis of the burners can have different inclinations relative to the vertical.
- the burners provided with a flange 14 even function correctly in horizontal disposition provided the pressure of the gas jets is sufficient.
- FIGS. 6 and 7 there is shown an embodiment particularly adapted for cooking. It is known that cooking burners must be controllable between certain limit values of gas pressure for heating purposes. If, in the case of the embodiments of FIGS. 1 to S and FIGS. 8 to 11), the gas pressure falls too much, the impact of the gas jet would be developed wholly on the distribution wall and the flames would no longer be held at the ledge but would burn directly on leaving the exit orifices and as a result the distribution wall would be exposed thereto. The poor aeration of such flames would give rise to carbonization.
- the distributor body 1 is annular with its internal face conical narrowing from top to bottom and serving as the distribution wall 4.
- the casing 3 is of cylindrical form terminating at its upper end in a conical wall 3b provided with exit orifices 2 whose axes are inclined relative to the vertical and coincide substantially with the upper edge or ridge 7 of the distribution wall 4.

- the angle of inclination of the distribution wall 4 relative to the horizontal is greater than that of the axes of the exit orifices.
- the angle subtended between the axes of the exit orifices 2 and the distribution wall is of the order of 10.
- the annular distributor body 1 rests on support feet 17 fixed on the support plate 16.
- the support feet 17 maintain the distributor body at a certain distance from the exit orifices 2 and thus ensure that the ambient air has free access to the jets of gas leaving the orifices 2. It would be equally possible to fix the support feet 17 on the cylindrical part of the casing 3.
- the upper edge or ridge 7 is followed by a ledge 5 extending this time radially outwards so as to form a frustum of a cone converging towards the center and the top of the distributor body 1.
- the ledge 5 subtends with the distribution wall an acute angle for example of the order of and is, on its outer edge, adjacent the low wall 6 disposed at least nearly perpendicularly to the cone frustum defined by the ledge 5.
- the upper end of the wall 6 terminates in the upper truncated surface 1b of the distributor body 1, this surface 1b being substantially parallel to that of the ledge 5 and adapted to permit secondary air access to the flames 10, 11.
- the flames 10, 1 1 are well held at 5, 6 on the distributor body 1.
- the flames initiate at the exit of the orifices 2 and are adjusted or corrected under the eflect of air entering the distributor body in the region of the space 18 between the upper part 3b of the casing 3 and the lower part of the distributor body 1 (see flames 10a, 11a in dotted lines). In this manner, this construction of burner can be also used without inconvenience with very feeble outputs of gas.
- FIGS. 8 to 10 are constructed similarly to those of FIGS. 1, 3 and 5 with the difference that the distribution walls 4, 4a are so near one another (FIGS. 8 and 9) or the distribution wall 4 has such an inclination relative to the axis of the casing 3, that they cannot be directly fixed on the casing if one Ll wrshes to marntarn and appropriate distance between the exit orifices 2 and the edge 7, a distance L] T whose functron wrll be explarned later.
- an extension piece 19 in the form of a solid body thick or thin, parallelipiped or cylindrical, perforated or not depending on the form of the distributor body 1, the extension piece 19 being perpendicular to the upper face 3b of the casing 3.
- the extension piece 19 integral with the upper wall 3b of the casing 3 has a parallelipiped form whereof the two lateral walls 19a, 19b subtend an obtuse angle with the distribution walls 4, 4a and are parallel to the axes of the exit orifices 2.
- the extension piece 19 can, besides, be grooved or channeled over all its height and a major part of its length.
- FIG. 9 has distribution walls 4, 4a very close together at their surfaces remote from the corresponding exit orifices 2, 2a and are fixed on their corresponding rails 3, 3a by extension legs 19c preferably disposed between two adjacent orifices 2 or 2a.
- the rails 3, 3a can be unitary.
- the exit orifices 2 formed in the upper wall 3b of the casing 3 and perpendicularly to the lower face 3d and upper face of the said wall 3b are inclined relative to the vertical so as to define generatrices of a cone whose apex is at the bottom.
- the axes of the exit orifices 2 coincide with the periphery of the inverted cone which constitutes the distributor body 1.
- the circumference of the large base of the cone 1 constitutes the sharp edge 7 from which extends radially inwards an annular ledge 5.
- the ledge S terminates on a low wall 6 and an annular flange l4 overlies the ledge 5.
- the conical distributor body 1 is cut and fixed on the extension piece 19 of cylindrical form which is itself integral with the upper wall 3b of the casing 3 within a circle defined by the series of exit orifices 2.
- the graph shown in FIG. 11 shows at the X-axis the calorific output Qc in millitherms/hour as well as the internal diameter of the gas exit orifices 2 or 2a in millimeters and at the Y-axis the lengths in millimeters of the difierent parameters of the distributor body 1 which is equally schematically shown in FIG. 1 I.
- the gas used for the different values indicated in this graph is the natural gas of LACQ employed with a suppression of 18 millibars.
- the curves L1, L2, L3, L4 indicate respectively the distance between the exit orifice 2 and the sharp edge 7, the distance between the two adjacent orifices 2 and 2a, the height of the wall 6 opposite the sharp edge 7 and terminating the ledge S, and the width of the ledge 5.
- the distributor bodies employed to establish this graph have distribution walls 4 inclined at 10 relative to the axis of the exit orifices.
