Definitions
- the invention relates to a lamella burner with a burner deck with a Burner frame connected with several parallel slats is, and with a pipe coil cooling the fins, the pipe sections led across the fins, connected to them and of coolant flowed through.
- Such lamella burners are from DE 197 24 817 A. and known from EP 0 913 632 A.
- the burner deck covers the burner pan with their gas mixture room.
- the burner deck is through the in the Pipe coil flowing coolant cooled.
- To the gas tightness to the outside To ensure the burner deck is closed by a frame that is sealed to the burner pan by means of a sealing element. Since the Pipe coil directly connected to the fins, these will be sufficient cooled and perform their function satisfactorily. But with that also The burner frame is cooled so that the sealing element is not overheated, must be a mechanical and good between the fins and the burner frame there is a heat-conducting connection. This is the case with known lamella burners achieved in that at least part of the slats with the Torch frame is welded.
- connection lugs which inserted in connection recordings of the burner frame and by deformation the part of the connection approaches protruding from the connection recordings and / or of the connection receptacles surrounding the burner frame Partial areas of the burner frame in the connection receptacles in a positive and / or non-positive manner held and connected to the burner frame.
- the same good results can also be achieved according to the invention by that the ends of at least part of the slats in connecting lugs with Retaining shots leak out into the holding shots holding elements of the burner frame can be inserted and clamped in such a way that the ones with the connecting lugs provided slats form and / or non-positively on the burner frame held and connected to it.
- connection technology No thermal process is included in the connection technology, so a Subsequent alignment work is no longer necessary, as is reworking the connection points.
- the burner deck can be manufactured inexpensively in a simple manner and still has the necessary for the function in the lamella burner Properties on.
- the lamellae are preferably made of aluminum, Cu alloys or ferritic stainless steel and the burner frame is made of ferritic stainless steel manufactured.
- connection lugs as pins are formed in the form of slots with a corresponding cross-section Connection recordings of the burner frame are introduced, and that the Tapping by bending, cupboarding or riveting the connection receptacles projecting part of the connecting lugs are deformed.
- connection recordings of the burner frame at least on two opposite one another Sides have sections formed as retaining tabs on the burner frame are bent out on the sides facing away from the slats, and that after the insertion of the connecting lugs, the partial areas in the direction of the Slats pressed in and so with the connecting lugs and the slats are positively and / or non-positively braced and held.
- connection technology is characterized by that the connecting lugs of the slats to the top and bottom of the burner deck have open connection slots as holding receptacles, at least one of them at an acute angle to the burner frame stands, and that the holding elements of the burner frame are designed as hooks are that can be inserted into the holding fixtures of the slats and under exercise a clamping force on the lamellae can be positively and / or non-positively fixed therein are.
- the burner frame is formed in two parts, each part with a Holding element is provided, and that the two parts of the burner frame after the connection with the slats themselves are interconnected.
- part of the lamellae 10 can be formed as a pin Leakage approaches 11 expire.
- the burner frame 20 is on the Connection points with the cross section of the connection lugs 11 Connection recordings 21 provided.
- connection approaches 11 With the projecting from the connection receptacles 21 Part bent on the leg of the burner frame 20, the front side the lamella 10 outside the connecting projection 11 against the leg of the Burner frame 20 is pulled and clamped to it. In this way becomes a mechanically firm and good heat-conducting connection between the lamella 10 and the burner frame 20, which is simple and inexpensive can be produced.
- connection receptacles 21 projecting parts of the connection lugs 11 reached become.
- riveting or caulking the outstanding parts of the connection lugs 11 may represent an equivalent connection technique, such as 3 and 4 show. This forms a kind of rivet heads 11 ", which are the Support the fins 10 turned away from the leg of the burner frame 20. The deformation the connection lugs 11 is made with the aid of a rivet punch 40 executed.
- connection receptacle 21 for the connection approach 11 of the lamella 10 are also punched out on two opposite sides Holding tabs as deformable portions 22 which the connection receptacle 21 in the initial state, i.e. when inserting the connection approach 11 of the lamella 10 limit, as the view of FIG. 6 illustrates.
- the subareas 22 face away from the slats 10 bent and can with a tool 40 in the plane of the leg of the Burner frame 20 are pressed, as the view of FIG. 7 shows. there the sub-areas 22 brace on the connecting projection 11 and pose a mechanically firm and good heat-conducting connection between the lamella 10 and the burner frame 20 ago.
- the slats 10 preferably consist of Aluminum, Cu alloys or ferritic stainless steel and the burner frame 20 made of ferritic stainless steel.
- the pipe sections 30 of the coil are in bores 12 of the fins 10 used and firmly connected to the slats 10.
- the connecting lugs 11 can the ends of the slat 10 also have holding receptacles 13 and 14, which as slots open towards the top and bottom of the burner deck are formed, into the holding elements 23 and 24 of a two-part burner frame designed as hooks 20.1 and 20.2 can be introduced.
- the upper holding receptacle 13 is at an acute angle inclined to the leg of the burner frame 20.1, the inclination of the holding receptacle 13 is larger.
- the holding element 23 and the Holding receptacle 13 made a positive and / or non-positive connection become.
