Definitions
- the present invention relates generally to a device forming a gas burner, in particular for a heating appliance in which the combustion of gas takes place around non-combustible elements having the appearance of logs for example, of the type comprising at least one gas pipe pierced with orifices and placed inside an open box filled with a non-combustible material forming a diffusion bed for the gas before its combustion and on which the logs rest.
- gas systems mounted in the hearth of the fireplaces to give the appearance of a wood fire by the flames which result from the combustion of the gas around non-combustible logs which imitate natural wood.
- FR-A-2 420 091 (BERGER) recommends the provision at the base of the fireplace, along the gas rail, of a pipe for diffusing air under pressure.
- BERGER BERGER
- GB-A-2 147 994 (COLLIER) provides for its part combination of a gas diffusion ramp or plate at the base of the fireplace with perforated air diffusion tubes; thus creating, within the gas diffusion bed, a primary air supply for combustion.
- GB-A-1 173 819 consisting in providing for a gas rail embedded in the diffusion bed a device for supplying a mixture of gas and primary air.
- the subject of the present invention is an improved arrangement of an open fire device of the type considered to be essentially characterized by the combination of a supply by a primary gas-air mixture with at least one supply of secondary air at the upper level of the diffusion bed. . Thanks to this arrangement, it is possible to obtain an almost complete combustion of the gas and to limit as much as possible the formation of soot.
- the supply of secondary air is located towards the peripheral part and towards the central part of the diffusion bed.
- the orifices of the gas conduit through which the primary gas-air mixture escapes are located opposite the bottom wall of the box to ensure better diffusion of the mixture through the bed broadcast.
- the burner device is mounted inside the hearth of a closed hearth chimney, which is advantageously equipped with an air-air heat exchanger to heat the air taken off. in the external environment surrounding the chimney and propel the hot air resulting in this external environment.
- FIG. 1 is a perspective view with partial tearing away of a burner device according to the invention
- Figure 2 is a sectional view with partial cutaway along the line II-II of Figure 1
- Figure 3 is a schematic sectional elevation of a chimney equipped with the device according to one invention.
- the device 1 forming a gas burner and as shown in FIGS. 1 and 2 comprises a hollow box 2 inside which is mounted at least one duct 3 connected to an external supply device 4 in communication with a gas supply line 5.
- the box 2 is of rectangular shape and has a bottom wall 8 delimited by four external side walls 9, which each extend, substantially at 90 °, by an external rim 10.
- the box 2 also has a central part 11 constituted by a flat surface 12, substantially coplanar with the external flanges 10 and connected to the bottom wall 8 by four internal side walls 13.
- the bottom wall 8, in its part delimited by the internal side walls 13, has an opening 8a.
- the external 9 and internal side walls 13 of the box 2 define between them and with the bottom wall 8, the internal space 14 of the box 2.
- the flanges 10 and the surface 12 of the box 2 are pierced with holes 16 for reasons which will be explained later.
- two conduits 3 are mounted parallel to one another in the interior space 14 of the box 2, and respectively on either side of the central part 11 of the box 2 bordered by the internal side walls 13 .
- Each conduit 3 is constituted by a tubular cylindrical envelope, with a diameter of the order of 30 mm for example, closed at one end and the other end of which is in communication with a supply device 4.
- Each duct is provided with orifices 17, which are advantageously located opposite the bottom wall 8 of the box 2.
- the supply device 4 associated with each duct 3 is in the form of a cylindrical enclosure 20 closed at one end by a wall 21 open at the other end and delimiting an interior chamber 22.
- the inlet pipe 5 of gas penetrates, sealingly, inside the chamber 22 through the wall 21, and is equipped at its end with a nozzle 23.
- the enclosure 20 is pierced with orifices 24 to put the chamber 22 in communication with the outside environment.
- the enclosure 20 has its open end bordered by a flange fixed around an opening 25 provided in the corresponding external side wall 9, so that the chamber 22 and in particular the nozzle 23 are substantially axially aligned with the duct 3 associated.
- the supply device is supplemented by a mixing device which is constituted in this example by a venturi tube 18 mounted inside the conduit 3, the inlet of the tube 18 coming substantially at the open end of the conduit 3 for form the entrance to it.
- the tube 18 extends inside the conduit 3 over a length which is of the order of a quarter of the length of the conduit 3.
- the interior space 14 of the box 2 is filled with a non-combustible material 25, such as vermiculite which is in the form of granules. This non-combustible material is also deposited on the edges 10 of the central part 11 of the box 2.
- An application of the device 1 forming a burner as described above, is shown diagrammatically in FIG. 3 where the device is mounted inside the hearth of a fireplace 30 with a closed hearth to constitute a heating appliance.
- a heat exchanger E is mounted inside the enclosure 31 and towards the upper part thereof. The exchanger E communicates, on the one hand, with the outside by the gills 37 and, on the other hand, by openings 39 and by an opening 40 provided in the upper wall 35 of the enclosure 31, with a conduit chimney 41.
- the device 1 forming a burner is mounted inside the enclosure 31 and rests, for example, on supports 45 provided for this purpose on the lower wall 31, so that air coming from the lower vents 38 can penetrate inside the central part 11 of the box 2.
- Logs 50 of a non-combustible material are suitably arranged on the non-combustible material 25 which fills the box 2 and which forms a diffusion bed.
- the pressurized gas from each line 5 leaves the nozzle 23 and enters the chamber 22 of the associated supply device 4.
- the pressure of the gas drives the air or primary air present in the chamber 22 and coming from the outside through the orifices 24, inside the venturi tube 18 where the primary gas-air mixture takes place.
- This mixture then propagates inside each conduit 3, is ejected through the orifices 17 of the conduits 3 and diffuses inside the diffusion bed 25.
- the primary gas-air mixture combines with the air or secondary air injected into the diffusion bed through the orifices 16 provided in the flanges 10 and in the central part 11 of the box 2.
- the thickness of the non-combustible material 25 located on the flanges 10 and the central part 11 of the box 2 can be adjusted to regulate the supply of secondary air.
- the quantity of gas admitted into each supply device 4 is itself adjustable by means of a valve not shown.
- the invention is in no way limited to the embodiment described and includes variant embodiments concerning in particular the shape of the box and the supply device which ensures the primary gas-air mixture.
