Definitions

  • the subject of the present invention is a burner device for a gas insert chimney comprising at least two bodies, a first body disposed on the front side of the insert and supplied with little combustion air for the production of large yellow flames and a second body. arranged on the rear side supplied with sufficient combustion air for the production of small blue flames.
  • the heating of the dwellings was carried out for a long time by the combustion of logs of wood in the hearth of a chimney.
  • Wood heating was gradually replaced by central heating using other means of heat production such as coal, fuel oil or gas.
  • the fireplaces have been preserved in some homes, mainly for their aesthetic side and the ceremoniity of the wood fire. Subsequently, given the increase in energy costs, it was planned to use the wood-burning fireplaces also as auxiliary heating. To go in this direction, the fireplaces were designed to allow the recovery of calories, and one of the main developments has been the production of inserts, which consist of a closed enclosure, placed in the hearth of the fireplace, and where combustion takes place, said insert being closed by a glass door which allows on the one hand the supply of fuel, and on the other hand the vision of the fire.
  • An insert makes it possible to control the combustion and to concentrate the heat, which can thus be recovered by heat exchanger devices arranged above said insert.
  • heating with wood has many drawbacks, the main ones being the need for a frequent manual supply of fuel, and tedious maintenance, in particular for the removal of ashes and the internal cleaning of the insert.
  • combustion In order to obtain optimal efficiency, combustion must be complete, that is to say that the gas must burn with sufficient oxidant, in this case air.
  • complete combustion of the gas results in the production of small blue flames which is not particularly aesthetic in a fireplace having the appearance of a conventional wood fireplace.
  • the device as described in this prior document, comprises a first burner ramp arranged between two artificial logs, placed at the top of the pyre and at the rear of the hearth, this first burner being defined so as to produce flames blue through an optimized gas / air mixture.
  • ramps are also placed between and / or in front of the artificial logs located in the front part of the hearth, therefore, defining the base of the pyre. These ramps are powered, essentially, in gas for the production of a yellow flame resulting from a mixture depleted in primary combustion air.
  • Document US-A-5,660,162 also describes a burner device for a gas insert chimney, this device essentially comprising two burner ramps, one of which, placed substantially in front of a artificial pyre corresponds to a ramp with high output for the production of blue flames and to bring to incandescence the first artificial logs of the pyre.
  • this in accordance with the present invention is rigorously managed in order to optimize this rate of production of carbon monoxide. Note that by reducing this, to a minimum, we simultaneously optimize the heat output of the fireplace.
  • the invention relates to a burner device for a gas insert chimney comprising at least two bodies, a first body disposed on the front side of the insert and supplied with weak combustion air for the production of large yellow flames and a second body disposed on the rear side supplied with sufficient combustion air for the production of small blue flames, these burner bodies being, on the one hand, placed integrally above a first plate and, on the other hand, comprising a part emerging above a second plate and pierced with a multiplicity of outlets for the gas / oxidant air mixture, at least partially at the periphery of these parts of the bodies persisting an interstice of width determined relative to said second plate for the passage of a secondary air gap.
  • the spacing distance between the first plate and a body of the burner is between 35 and 45 mm.
  • the width of the gap remaining at the periphery of the parts of the bodies of the burner emerging above the second plate is chosen to be of the order of 5 to 10 mm, preferably equal to 7 mm.
  • the advantages resulting from the present invention consist in that, while obtaining the appearance of a wood fire through the gas burner device, the operation of the latter is optimized for maximum heat output and a production rate of carbon monoxide as low as possible.
  • the short distance separating the first plate and the burner bodies makes it possible to avoid turbulence at the openings for supplying combustion air, in particular as regards those of the front body intended to produce large yellow flames. This ensures a constant proportion of the gas / combustion air mixture and, thus, regular flames.
  • the outlet orifices of the front body of the burner are distributed irregularly, so as to obtain yellow flames of different heights for the union of more or less orifices and for as close as possible imitation of a fire.
  • wood Of wood.
  • This burner device comprises two bodies 1 and 2, the body 1 is intended to be placed at the front of the insert, not shown, on the side of the glass door thereof, while the body 2 is intended to be placed in the back.
  • the bodies 1 and 2 emerge, in part, above a plate 3, while they rest on a plate 4, to which they are secured by lugs 40, only two of which are visible in FIG. 1.
  • lugs 40 only two of which are visible in FIG. 1.
  • the parts 10 and 20 respectively of these bodies 1, 2 emerging from the plate 3 are pierced with holes 11, 21 respectively.
  • the body 1 has at one end a gas supply nozzle 5 opening into a chamber 12 pierced below with an opening 13, and separated from the rest 14 of the body 1 by a venturi 15.
  • the nozzle 5 injects the gas into the chamber 12 into which the combustion air is brought by suction through the opening 13.
  • the gas / combustion air mixture produced at the venturi 15 spreads into the part 14 of the body 1 and exits through the orifices 11.
  • body 2 is of general design identical to that of the body 1, with however some differences.
  • combustion air inlet 13 of the body 1 is smaller than that of the body 2, so that the mixture is less rich in combustion air, in order to obtain an incomplete combustion producing yellow flames, while the body 2 where combustion is complete due to a sufficient supply of combustion air, produces small blue flames.
  • the orifices 21 of the body 2 are regularly distributed, it is not the same for the orifices 11 of the body 1, which can for example be joined in bundles, so that the orifices 11 of each of the packages can be combined in the creation of a large yellow flame.
  • the combustion air comes from the ambient medium, and it reaches the opening 13 along the plate 4 and the bodies 1 and 2.
  • the dimensions of the opening 13 are calculated so as to admit the quantity adequate combustion air, in order to obtain the mixture allowing the production of large yellow flames at the level of the body 1.
  • turbulence at the combustion air intake can modify the quantity of combustion air admitted, resulting in more or less regular yellow flames, not giving the appearance of a wood fire.
  • a well-defined space between the body 1 and the plate 4 a space of the order of 35 to 45 millimeters, makes it possible to reduce turbulence while allowing a good supply of combustion air.
  • the burner device according to the invention thus makes it possible to give the appearance of a wood fire by producing in front of regular yellow flames, but of different heights, while providing heat at the rear, which can be recovered by appropriate means.
  • the bodies 1 and 2 are supplied separately with gas, and that by means of a bypass, not shown, the body 1 is supplied weakly with gas, sufficient for the production of yellow flames, so that the essential consumption and therefore calorific intake is achieved at the level of the body 2 which has an optimal yield.
  • the burner according to the invention is intended to be placed in an insert and can be hidden behind dummy logs.
