Definitions

  • the present invention relates to a burner device for gas insert chimneys comprising at least two bodies, one first body disposed on the front side of the insert and supplied low in 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.
  • Wood heating was gradually replaced by the central heating using other means of production heat such as coal, fuel oil or gas.
  • An insert allows to control the combustion and to concentrate the heat, which can thus be recovered by devices heat exchangers arranged above said insert.
  • wood heating has many disadvantages of which the main ones are the need for a frequent manual fuel supply, and a tedious maintenance, especially for ash removal and internal cleaning of the insert.
  • combustion In order to obtain optimal efficiency, combustion must be complete, i.e. the gas must burn with sufficient oxidizer, in this case air. However, a complete combustion of the gas results in obtaining small blue flames which is not particularly aesthetic in a fireplace having the appearance of a fireplace classic wood.
  • the device as described in this document front, has a first burner ramp arranged between two artificial logs, placed at the top of the pyre and at the back of the hearth, this first burner being defined so able to produce blue flames through a mixture optimized gas / air.
  • ramps are still placed between and / or in front of the artificial logs located in the front part of the fireplace, 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.
  • the document US-A-5,660,162 also describes a device for burner for a gas insert chimney, this device comprising, essentially two burner burners, one of which is placed substantially at the front of an artificial pyre corresponds to a high efficiency ramp for the production of blue flames and bring the first artificial logs of the stake.
  • the invention relates to a burner device for a gas insert chimney comprising at least two bodies, one first body disposed on the front side of the insert and supplied low in 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, these burner bodies being, on the one hand, solidly placed above a first plate and, on the other hand, comprising a part emerging above a second plate and pierced with a multiplicity of orifices of outlet of the gas / combustion air mixture, at least partially in periphery of these persistent body parts an interstice of width determined with respect to said second plate for the passage of a secondary air gap.
  • the distance between the first plate and a body of the burner is between 35 and 45 mm.
  • the width of the gap remaining in periphery of parts of the burner body emerging above of the second plate is chosen on the order of 5 to 10 mm preferably equal to 7 mm.
  • the short distance separating the first plate and the burner bodies avoids turbulence at level of the combustion air supply openings, especially with regard to those of the front body intended for produce large yellow flames. This ensures a constant proportion of the gas / combustion air mixture and, thus, regular flames.
  • the outlet ports of the front body of the burner are distributed irregularly, so as to obtain flames yellows of different heights for the meeting more or less orifices and for as faithful an imitation as possible of a wood fire.
  • This burner device has two bodies 1 and 2, the body 1 is intended to be placed at the front of the insert, not shown, on the glass door side of it, while the body 2 is intended to be placed at the rear.
  • 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 Figure 1. Note that the parts respectively 10 and 20 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 nozzle 5 for supplying gas opening into a chamber 12 pierced below by a 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 in which is brought, by suction through the opening 13, the air oxidizer.
  • 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 combined in bundles, so that the orifices 11 of each of the packages can associate in creating a big yellow flame.
  • the combustion air comes from the ambient environment, and it reaches the opening 13 along the plate 4 and the bodies 1 and 2. From plus, as seen above, the dimensions of the opening 13 are calculated to admit the right amount of air oxidizer, in order to obtain the mixture allowing the production large yellow flames on the body 1.
  • turbulence at the combustion air intake can modify the quantity of combustion air admitted, with for consequence of more or less regular yellow flames, do not not giving the appearance of a wood fire.
  • a well defined space between the body 1 and the plate 4 space of the order of 35 to 45 millimeters, reduces the turbulence while allowing a good air supply oxidizer.
  • the burner device according to the invention thus makes it possible to give the appearance of a wood fire by production forward regular yellow flames, but of different heights, while providing heat to the rear, which can be recovered by appropriate means.
  • the bodies 1 and 2 are supplied separately with gas, and that through a bypass, not shown, the body 1 is supplied with a small amount of gas, enough to produce yellow flames, so that the main part of consumption and therefore of calorific intake is carried out 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 logs dummy.
