Burners, in particular rust-shaped burners for gas-heated devices

The invention relates to a burner, in particular grate-shaped burner for gas-heated appliances, in which at least one elongated burner chamber with a gas inlet opening is placed transversely on a distributor piece, which forms the connection to the gas supply line with a Gas supply nozzle is provided.

Burners of the type mentioned are already known. Are the burner chambers, for example, as diffusion series burners formed, so result with some types of gas, in particular with natural gas, with relatively high pressures in the burner chambers Difficulties in assembling the burner because of the connection points between the distributor and the the burner chambers can hardly be properly sealed.

The invention is based on the stated deficiency to fix.

The object is achieved on a burner of the type mentioned according to the invention in that the distributor

piece with an upward ridge than the burner, chamber supporting bridge is provided, which has a recess corresponding to the outline of the lower part of the burner chamber has, which for the gas supply to the burner chamber with the interior of the distributor piece via a bore is connected, against which the burner chamber with its gas inlet opening is sealed by means of the support bridge of the distributor piece screwable fastening straps can be pressed.

In a preferred embodiment it is provided that the gas outlet opening of the distributor piece with an in formed the recess of the supporting bridge protruding approach is, on which the burner chamber can be plugged with its gas inlet opening, which either in the ground or on a pipe socket of the burner chamber is formed.

In the preferred embodiment, the design can be such that a seal between the edge of the gas inlet opening the burner chamber and the base surface of the recess is arranged.

But there is also the possibility that the seal between an annular shoulder formed by the pipe attachment the burner chamber and corresponding support shoulders is provided on the recess.

Furthermore, the training is made so that the burner chamber can be pressed onto the manifold by means of two fastening tabs that overlap their edge.

Finally, when assembling the burner, it is advantageous that for a rust-shaped burner with several Burner chambers through all fastening tabs, which each overlap the edges of two adjacent burner chambers a common angled longitudinal leg are connected to one another and can be placed as a unit, which is attached to the support bridge? of the distributor piece can be screwed on.

The inventive design of the burner offers a simple and cost-saving assembly of a burner, in the case of a grate-shaped burner, the burner chambers are centered and parallel at the same time when placed on the distributor piece be aligned to each other. An essential feature of the invention is that a perfect seal at the connection points between the distributor piece and the attached burner chambers even at higher pressures of the gas, such as natural gas, is guaranteed. In addition, the distributor piece forms in the area of the supporting bridge and the fastening straps for the burner chambers attached thereon between the diffusion burner chambers due to the vortex of the sucked-in air, a zone in which the outflowing gas and the sucked-in air ^ Mix faster and become more ignitable. An overfire is already initiated between the combustion chambers, before too much gas has escaped.

The object of the invention is based on one in the drawing schematically illustrated embodiment explained in more detail. Show it:

Fig. 1 is a plan view of the invention trained burner;

FIG. 2 is a front view according to FIG. 1, partly in section;

3- a broken front view according to FIG. 1 in section with a different seal the burner chambers used.

The embodiment shown in the drawing is directed to a rust-shaped burner for gas-heated devices, which consists essentially of a distributor piece 10, on which elongated combustion chambers 11 as Diffusion row pusher with a gas inlet opening 12

are placed across. The manifold 10 is with a the connection to the gas supply line forming gas supply nozzle 13 is formed, on which for screwing with a union nut 14 is provided in a gas supply line (not shown). The same of course also applies to a burner with only one or two burner chambers, which are arranged on a correspondingly designed manifold are.

According to the invention, the distributor piece 10 is provided with an upwardly directed web 15 as a supporting bridge which supports the burner chambers 11 and which has recesses 16 corresponding to the outline of the burner chamber 11. For the gas supply to the burner chamber, each recess 16 is connected to the interior of the distributor piece 10 via a bore 17, against which the burner chamber 11 with its gas inlet opening 12 can be pressed with a seal by means of fastening straps 18 that can be screwed onto the support bridge 15 of the distributor piece 10. According to the exemplary embodiment shown, the gas outlet opening 17 of the distributor piece 10 is designed with a projection 19 protruding into the recess of the support plate 15, onto which the burner chamber 11 with its gas inlet opening 12 can be plugged. The gas inlet opening 12 can be formed either in the bottom or on a pipe socket 20 of the burner chamber 11. In a preferred embodiment (Pig. 2) it is provided that a seal is arranged between the edge of the gas inlet opening 12 of the burner chamber 11 and the base surface of the recess 16. In another embodiment according to FIG. 3, a seal 211 is provided between an annular shoulder 22 formed by the pipe socket 20 and the bottom of the burner chamber 11 and corresponding support shoulders 23 on the recess 16. The burner chamber 11 can be pressed against the distributor piece 10 by means of two fastening tabs 18 which overlap their edge, so that a perfect

Sealing of the connection point between the distributor piece 10 and the attached burner chamber 11 even at relatively high pressures of the gas, such as, for example Natural gas, is guaranteed.

The assembly of the burner is simple, time-saving and ensures a good seal. After inserting the Seal 21 or 211 is the burner chamber 11 in the recess 16 of the support bridge 15 of the distributor piece 10 is inserted, with the penetration of the projection 19 of the gas from outlet opening 17 in the gas inlet opening 12 or the pipe socket 20 at the bottom of the burner chamber 11, the latter centered and is aligned accordingly, especially in the case of grate-shaped burners. The assembly is, however also simplified by the fact that for a grate-shaped burner with a plurality of burner chambers 11, all of the fastening tabs 18, which are each the edges of two adjacent Burner chambers 11 overlap by a common angled Longitudinal legs 24 are connected to one another and can be placed as a unit, which is attached to the supporting bridge 15 of the Distributor 10 can be screwed on by means of screws 25.
