Definitions

  • the invention relates to a linear burner supplied with combustible gas and combustion air.
  • such a burner is also called a ramp burner.
  • It is a burner comprising at least one row of injectors, each injector extending through an opening in a wall of a body of the burner internally forming an air distribution chamber with which said injectors communicate, these injectors being arranged substantially perpendicular to a longitudinal direction in which the body of this burner extends.
  • This type of burner has the advantage of offering a very wide range of heating power.
  • the aforementioned publication FR 2 641 601 proposes to mechanically vary the volume of the burner body, so as to connect to the supplies provided for this purpose a more or less large number of injectors.
  • the object of the invention is in particular to solve the above-mentioned difficulties, by proposing a burner devoid, on the body of the burner, of a gas distribution chamber and of mechanical members for controlling the number of injectors to be supplied, allowing thus improving the general operation and reliability of the system by reducing manufacturing costs.
  • the burner of the invention is characterized in that the injectors with which it is provided are connected individually, or in groups, to a series of fuel gas supply tubes, or to a mixture of combustible gas and air, these tubes passing through the body of the burner to connect externally to a distribution box itself connected to a main supply pipe in which circulates combustible gas or a mixture of combustible gas and air, this housing comprising adjustment means for selectively supplying, in whole or in part, said supply tubes connected to the injectors.
  • the burner body that is to say its frame, contains only one air distribution chamber, without a combustible gas distribution chamber.
  • this burner body may also be in the form of a duct or channel of substantially rectangular or square section in which a slot will be formed extending in the longitudinal direction of the body and through which the injectors will protrude.
  • the adjustment means available to the distribution box adjoining the burner body may consist of metering means for measuring the supply of combustible gas or gas / air mixture to at least some of the injectors.
  • a linear burner 1 is thus seen illustrated according to the invention, comprising an elongated or constructed body 3 internally defining an air distribution chamber 4 intended to supply air (primary or secondary) a series of injectors shown diagrammatically in 5, themselves supplied with combustible gas or with a combustible gas / air mixture by a network of tubes 7a, 7b, 7c ... connected, outside the body 3, to means adjustment identified as a whole 9 and intended to selectively supply, in whole or in part, said injector supply tubes.
  • the adjustment means 9 are housed in a distribution box 11 laterally attached to the body 3 and shown in phantom lines.
  • the injectors 5 are distributed in rows forming in this case a single row or line extending in the longitudinal direction 3a of the body 3.
  • the body 3 in question may advantageously be in the form of a metal conduit or channel of substantially rectangular or square section with a longitudinal slot 12 provided for the passage of the injectors and their adaptation to the body, the interior volume 4 of this body being adapted to form a suitable "air box”.
  • the body 3 can either be open at its opposite longitudinal ends (see FIG. 3) for an air supply atmospheric, either closed at said ends and then connected to a supply air supply line (pressurized air) shown diagrammatically at 16 in FIGS. 1 and 5 and opening into volume 4.
  • a supply air supply line pressurized air
  • the injectors will of course communicate, in a conventional manner, with this interior volume 4 by a peripheral air passage 18 formed at the level of the slot 12, inside an air injection cone or ring 20 surrounding each injector (see in particular Figures 2 and 5).
  • these injectors are here fixed transversely inside the body 3 by flanges 13, 15 and fixing screws 17, so as to pass through an upper wall 3b of this body, through the long slot 12 formed in the direction of the longitudinal direction 3a of the body.
  • the illustrated injector is connected, inside the body, to one of the supply tubes marked 7a, the other injectors in the row being them, either connected individually to other identical supply tubes 7b, 7c ... joined together in sheet 19, or connected in group to a supply tube of larger diameter such as 7d, the connection principle adopted being a function of the field of application of the burner and of the degree of adjustment of the desired power of the injectors taken independently or in small groups.
  • the connection principle adopted being a function of the field of application of the burner and of the degree of adjustment of the desired power of the injectors taken independently or in small groups.
  • FIG. 1 it will moreover be noted on this subject that if the first and fourth injectors are supplied individually by the tubes 7b and 7c, the second and third are on the other hand supplied jointly by the tubes 7a and 7b. (In FIG. 3, another feeding principle has also been envisaged).
  • the tubes 7a, 7b, etc. are themselves connected to a general fuel gas supply duct or a fuel gas / air mixture 21.
  • the distribution box 11 will preferably be fixed laterally to a longitudinal end of the body 3, via a fixing flange 23 in which a passage 25 has been provided for the supply pipes 7a , 7b ... (see Figure 5).
  • the adjustment means 9 the role of which, as has been said, is to allow, from outside the burner body, to selectively supply all or part of the supply tubes connected to the injectors, may have various shapes. It is however advisable to choose means allowing the dosing of the fuel gas supply or gas / air mixture of at least some of these injectors.
  • these means consist of a series of solenoid valves 24 interposed inside the volume of the housing 11 on each supply tube 7a, 7b ..., downstream of their common connection to the general conduct 21.
  • the adjustment means in question have been replaced by a sliding sector system comprising a fixed part 27 in the thickness of which are locally formed orifices 29 in number at least equal to the number of tubes supply 7a, 7b ... to which these orifices are connected on one side, communicating, on the other side, with the general supply line 21, via a distribution chamber 31 (see FIG. 5).
  • a moving part 33 In contact with and opposite the fixed part 27 slides, for example in rotation, a moving part 33 having through its entire thickness a slot 35 (see Figures 3 and 4) such that it can cover in a gas-tight manner, or uncover, all or part of the orifices 29 of the fixed part 27, by displacement of the movable part .
  • this movable part 33 may be in the form of a rotary sector having a slot 35 in an arc of a circle, the orifices 29 of the fixed part 27 then being in correspondence , also arranged in an arc.
  • control linkage 37 that can be actuated from outside the housing to act on the moving part 33, via a plate 39.
