- combustible gas mixture for example air / natural gas mixture, air / propane, air / butane, air / biogas, or air / fuel vaporized, a cylindrical burner surface combustion.
- a pressure and flow stabilizing device for such a gas burner, a gas burner equipped with this stabilizer device, and a method for stabilizing the pressure and the flow of the gas mixture feeding the burner.
- a cylindrical surface-burning gas burner comprises a perforated cylindrical wall pierced with a multitude of small orifices, a discoid bottom wall and an inlet opening, through which a pre-mixed combustible gas mixture (premix) is introduced into the burner, for example by means of a fan or a turbine.
- premix combustible gas mixture
- the cylindrical wall is a perforated stainless steel sheet, the orifices being circular holes and / or slots of very small section.
- the invention is also applicable, however, to grid-like walls or as a layer of porous material resistant to high temperatures (for example woven fibers made of refractory material).
- the combustible gas is distributed inside the burner and escapes radially through the orifices of the cylindrical wall; the burner being lit, the outer face of the wall acts as a combustion surface, each orifice generating a radial flame of greater or lesser height, depending on the area of its section and the gas flow.
- This type of burner is particularly suitable for equipping a boiler, for domestic or industrial use, provided with one or more tubes (circular section or other) surrounding the combustion surface.
- One or more fluids to be heated circulates in this (these) tube (s) which is (are) licked (s) by the hot gases from the combustion surface.
- the invention relates more particularly to the stabilization of the pressure and the flow rate of the gas mixture inside the burner, so as to obtain a complete combustion and evenly distributed over the entire cylindrical combustion surface of the burner, with a uniform flame height for optimal performance while reducing emissions of carbon monoxide (CO) and carbon dioxide (CO 2 ).
- CO carbon monoxide
- CO 2 carbon dioxide
- the quality and the hygiene of the surface combustion obtained by this type of burner depend on several parameters, in particular on the dimension (section of passage) of the orifices made in the cylindrical wall, and of their mutual spacing (rate of openwork). perforated wall).
- the uniformity of the gas flow over the entire combustion surface conditions the combustion height and its regularity over the entire surface, on which the emission of CO and CO 2 depends.

- the connecting sleeve M is provided with a safety valve comprising a flap A, hinged at the top, the function of which is to prevent backflows from burner to the fan when it is stopped. This is useful especially when several devices are connected to the same chimney.
- the valve is closed when the shutter, under the effect of its own weight, is in the vertical position Ao shown in broken lines in the figure.
- the difficulty is further increased in case of remote positioning of the fan relative to the burner ( Figure 2) or the presence of a valve at the burner inlet ( Figure 3).
- the object of the invention is to solve these problems, by proposing a device for stabilizing pressure and flow of simple design, without moving parts, light and inexpensive, practically inducing no pressure drop, adapted to be placed at the inlet of the burner to significantly improve the distribution of the gas mixture inside the burner and thus ensure a uniform supply of all the orifices of the combustion surface, generating a constant flame height over all this surface.
- this pressure and flow stabilizing device is intended to equip a gas burner having a perforated cylindrical wall acting as a combustion surface, a bottom wall and an inlet opening, through which a combustible gas mixture is introduced inside the burner.
- the device consists of a grid adapted to be positioned inside said inlet opening, and comprising a central ring surrounded by a series of deflecting blades, this grid being thus shaped that it authorizes the free passage of the central portion of the gas mixture flow entering the burner through the central ring, while said deflector blades generate a swirling movement of the peripheral portion of this flow entering the burner from the outside of the central ring.
- the burner is fed simultaneously with two gaseous flows of different configurations, namely an external cyclonic vortex which moves along an approximately helical path towards the bottom wall of the burner, and a central undisturbed flow, or little disturbed, which also moves to the bottom of the burner while relaxing inside the cyclone.
- the patent document EP-I 538 395 relates to a cylindrical gas burner internally provided with a device for reducing the acoustic resonance phenomena and, correlatively, the burner noises.
- This device comprises parallel or "cross" partitions, which prevent any swirling movement of the gas mixture feeding the burner, which thwarts the homogenization and good distribution of this mixture, contrary to the desired objective.
- German utility model DE 9013114 U describes a disk intended to equip an oil or gas burner.
- This disk is provided with a central opening through which the fuel (fuel) and a first part of the air (oxidizer) pass, as well as a series of radial slots which are crossed by the other part of the necessary air. to combustion.
- This document does not specify which form of burner this disc is associated, nor fortiori, that the disc is positioned inside the inlet opening of this burner.
- the central ring is circular, and is coaxial with the perforated cylindrical wall (when the device is mounted on the burner); said blades extend radially with respect to the axis of the perforated cylindrical wall (when the device is mounted on the burner), with a regular angular distribution;
- the number of blades is between 6 and 30, and advantageously between 11 and 25;
- said blades are plane blades, all identical and of constant width, which are inclined in the longitudinal direction, their plane forming an acute angle with respect to the axis of the perforated cylindrical wall;
- said angle has a value of between 15 and 45 °, preferably of the order of 30 °;
- said blades are integral with the central ring
- Said grid comprises a circular outer ring, whose blades are integral, adapted to be fitted and immobilized in the burner inlet opening;
- the central ring is a sleeve whose length is substantially equal to the axial dimension of the blades (suitable solution for a burner of low to medium length);
- the central ring is a sleeve whose length is greater than the axial dimension of the blades (suitable solution for a burner of great length).
- the invention also relates to a cylindrical burner with surface combustion equipped with a pressure-stabilizing device as described above.
- FIG. 6 is a side view, in section, of the same device, the section plane being referenced VI-VI in Figure 5;
- - Figures 7 and 8 show a second possible embodiment of the stabilizer device of the invention, these views being similar, respectively, to Figures 4 and 6 of the first embodiment;
- FIG. 9 shows a third possible embodiment of the stabilizer device of the invention, this view being similar to Figure 4 of the first embodiment
- FIG. 10 is an axial section of a burner provided with a stabilizer device according to the first embodiment
- FIG. 11 is a view similar to FIG. 10, intended to illustrate the operation of the device by showing how the gas flow is distributed inside the burner;
- Figure 12 is a perspective view, and in section, similar to Figure 11;
- FIG. 13 is a view similar to Figure 11, but with a burner of greater length, provided with a stabilizer device according to the second embodiment.
- the device shown in Figures 4 to 6 consists of a grid, for example stainless steel sheet thin.
- This grid 4a is composed of a pair of concentric rings, one central 5a, the other outer 7, shaped cylindrical sleeves of short length, common axis X-X ', as well as a series of blades 6.
- the grid comprises 12 blades, distributed at 30 ° all around the central ring. They are fixed at their ends, for example by welding, to each of the two sleeves 5a and 7.
- the outer diameter of the ring 7 is chosen to correspond to the internal diameter of the cylindrical wall of the burner to be equipped, so that the grid can be inserted and maintained without play in the burner inlet opening, coaxially with it.
- blades 6 all identical, are flat blades of constant width. They are inclined in the longitudinal direction, so as to form an acute angle, designated ⁇ in Figure 6, relative to the axis X-X '. As an indication, this angle has a value of the order of 30 °.
- the central ring 5a defines a cylindrical channel 8, of axis X-X ', allowing the free passage of gases.
- the spaces between blades 6 define an annular peripheral passageway 9 for the gases.
- the device which is the subject of the second embodiment shown in FIGS. 7 and 8 consists of a gate 4b which is different from the gate 4a which has just been described by the fact that the length i of its central sleeve, referenced 5b, is significantly larger than the axial dimension e common to the blades 6 and to the outer ring 7. As will be seen below, with reference to FIG. 13, the portion of this sleeve 5b that exceeds the general plane of the grate is intended to penetrate inside the burner.
- the device which is the subject of the third embodiment shown in FIG. 9 consists of a gate 4c which differs from the gate 4a in that it does not comprise an external ring.
- the blades 6 are intended to be positioned and apply directly against the cylindrical inner face of the burner inlet opening.
- These blades therefore have a length such that their outer edge fits into a cylindrical envelope (fictional) whose diameter corresponds to that of this inner face.
- a stabilizing device 4b according to the first embodiment described above is fitted axially into the inlet opening 10 of the burner and is retained therein, for example under the effect of the simple friction due to a certain tightening between the external face. of the ring 7 and the inner face of the mouth of the cylindrical wall 2.
- the ring 10 is provided with a flange 70 forming a stop, which limits its penetration inside the burner body.
- FIGS 11 and 12 illustrate the mode of action of the device.
- the central flow symbolized by the arrows X, is a regular or even laminar flow, generally trajectory in translation along X-X 'towards the bottom 3.
- the gaseous mass tends to flare, in the form of cone, then "in trumpet", as shown by the outline of the envelope Ea.
- the external flow symbolized by the arrows Y, follows a swirling trajectory, in a helix, at a high speed, around the central flow, this trajectory combining an axial translation movement and a rotational movement (twisting) which is printed to it by the inclination of the deflecting blades 6.
- the external flow surrounds the central stream over almost its entire length (upstream side).
- the combination of these two flows ensures a regular distribution of the flow rate and the pressure of the gas inside the burner, over its entire length and over its entire periphery (over 360 °).
- the dimensions of the stabilizer device must naturally be adapted to the structure and dimensions of the burner.
- the burner la just described has a perforated wall 2 made of stainless steel sheet whose thickness is 0.3 mm.
- the rate of perforation of the wall is of the order of 30%.
- La and Da in FIG. 10 Its length and internal diameter, respectively designated La and Da in FIG. 10, are respectively 160 mm and 70 mm.
- the stabilizing device 4a can also be made of a thin sheet of stainless steel.
- the outer ring 7 has a diameter of 70 mm with a functional tolerance allowing it to fit without play, or even with a certain tightening, into the burner inlet opening.
- the central ring 5a has a diameter of 24 mm.
- the axial dimension e of the device is 10 mm.
- Burner Ib shown in FIG. 13 is similar to burner 1a except for its longer length Lb.
- Lb 240 mm
- Db 70 mm.
- the stabilizing device 4b is identical to the device 4a, except for the sleeve constituting the central ring 5b, whose length i is substantially greater than e.
- this sleeve 5b has the effect of channeling the central flow so that it diverges less rapidly than the central flow of the first embodiment, so that it can reach the bottom wall 3, plus away from the opening as before.
- the envelope Eb which separates the central flow from the external cyclone flow flares more progressively downstream, inside the burner Ib, than the envelope Ea inside the burner la.
- the operating mode of the two stabilizers is similar, and generates a uniform distribution of gas flow and pressure, resulting in a regular flame height and optimal combustion hygiene.
- the entrance opening is similar, and generates a uniform distribution of gas flow and pressure, resulting in a regular flame height and optimal combustion hygiene.
- the stabilizer device could be shaped so as to cap (from the outside) the inlet mouth of the burner instead of fitting inside.
