Definitions
- the invention relates to a gas burner with a base part, which has a gas supply has, and with a slat block, which is attached sealed to the base part, wherein the slat block is formed from slats that are parallel to each other is, which are pushed onto cooling elements designed as cooling tubes, wherein heat can be coupled out from the fins to the cooling elements and the Lamella block is surrounded by a frame that the sides of the lamella block running in the flow direction of the fuel gas is at least partially covered and connected to it.
- a gas burner of this type is known from US-A-4,137,905.
- the slats are parallel to the flow direction of the exhaust gas and are on cooling pipes with at their ends Connected heating elements that form the frame and of the one to be heated
- the heat exchange between the fins on the The cooling roller is only in the area of the lamella bores for the cooling pipes and over this to the liquid to be heated.
- the heating elements are multi-layer Slat block connected in series and with one inlet and one Provide outlet connection for the liquid flowing through.
- This known gas burner is not only complicated in construction, it also has one poor efficiency in heat transfer from the slats and frames too the liquid to be heated.
- the frame can be simple and that of heat absorbed by the frame - also from the exhaust gas - is transferred to the cooling pipes transmitted, which must be led out of the frame.
- a simple structural design of the frame is given if he has two legs at right angles to each other, one of which sits on the base part and is in operative connection with the seal and the second leg is connected to the slats via the thermal bridges. The The first leg can be applied to the surface of the seal. Thereby, that the first leg is bent at right angles to the second leg the seal can be held spaced from the lamella block become. This significantly reduces the influence of heat radiation.
- a preferred variant of the invention provides that the frame has a collar carries, which is arranged in the region of the flame side of the slat block and this protrudes, and that the collar via an expansion joint with the frame connected is.
- the frame over the flame side of the slat block protrudes, the flames are stabilized.
- the arrangement introduces a high proportion of heat radiation into the collar. This can lead to thermal deformation of the collar.
- an expansion joint between the collar and the frame the thermal deformations are not transferred into the frame.
- the gas burner in side view and in section shown.
- the gas burner has a base part 10, which is a duct system is crossed.
- This channel system serves as a gas supply 11 fuel gas is introduced into the gas supply 11 via an injector arrangement 11a.
- the fuel gas flows to a lamella block 30.
- the slat block 30 is cuboid and has a large number of mutually parallel, in the image plane one behind the other slats 31.
- the Fins 31 are provided with circular openings through the cooling tubes 32 are threaded. Heat can be extracted from the fins 31 via the cooling tubes 32 become.
- the lamella block 30 is surrounded on all sides by a frame 20 surround.
- the frame 20 lies with one leg 22 on the respectively assigned one Side of the slat block 30. Another of the legs 22 Leg 21 angled horizontally. The other leg 21 is located flange-like on a support section 12 of the base part. The leg 21 is supported on a seal 13 which is in a groove in the base part 10 is included. The leg 21 merges into a holding section 27 which is bent from the leg 21 and protrudes upward.
- the slats 31 are coupled to the legs 22 of the frame 20 via thermal bridges 24. In the drawing there are two alternative options for attachment of the thermal bridges 24 shown. Firstly, on the underside of the slat block 30 applied a welded joint in the form of a fillet weld.
- a thermal bridge consists in that on the front ends of the slats 31 a solder is applied, which is a material connection to the frame 20 manufactures.
- a collar 23 is placed on the frame 20.
- an expansion connection 28 is provided on the frame 20.
- the collar 23 follows the expansion joint 28 into a horizontal bend 25 about.
- a support section 26 adjoins the fold 25. If the Collar 23 is placed on the frame 20, the support section 26 comes with the holding section 27 in register. In this assembly position, the Support section 26 with the holding section 27 with the aid of the expansion element 28 are connected.
- the lamella block 30 can be fixed to the base part 10 by means of closures 14 become.
- fuel gas is passed through the gas supply 11 of the base part 10. This flows between the individual slats 31 through the slat block 30 therethrough. There it is ignited by means of an ignition 33. This creates a flame front that extends over the entire surface of the lamella block 30 extends.
- the radiant heat generated during the combustion becomes partial introduced into the collar 23. From here it is transferred to the leg 22 of the frame 20. The heat is largely from the leg 22 again passed back over the thermal bridges 24 into the cooled fins 31. Thereby the leg 22 can be largely kept free from the effects of heat, so that harmful temperature influences are kept away from the seal 13 can be.
