Definitions
- the invention relates to a lamella burner with a cooling line Cooling system with parallel pipe sections, as punched and bent parts trained slats with openings and with these on the Line sections are pushed on, the slats by means of protruding thereon Spacer elements on the line sections essentially to one another parallel and spaced so that between adjacent slats Guide channels for a fuel gas-air mixture are formed.
- Such a lamella burner is known from DE-U-297 10 281.
- This Known lamellar burners form the horizontally folded on one side Spacer elements at the same time, the one with many openings, as the focal surface serving cover of the cooling system. This requires a large distance the slats pushed onto the line sections and thus the one in the exhaust gas flow heated surfaces of the slats, that is the efficiency of the Heat exchange is low.
- the distance between the slats on the line sections can can also be kept small in that they are in the area of the openings welded or soldered to the line sections to their To keep distances from each other. This makes the production of the lamella burner more expensive considerably.
- the spacer elements are turned out as collar-shaped passages, which are in contact with the adjacent slat.
- spacer elements between the slats are again used used, which protrude in one piece on the slats and on the adjacent one Apply slats.
- these spacer elements are in the area of the breakthroughs for the line sections as circular arches. In this way, the slats can be parallel and in be kept a small distance from each other. This leads to an essential one Cost reduction in the manufacture of the lamella burner.
- a possible variant of the invention is characterized in that the lamellae made of a thin-walled sheet steel and on their flame side Areas are provided with widenings.
- the thin-walled lamella guides them generated heat well, so that it is simply on the cooling system constant operating temperature can be maintained.
- the widenings which are arranged on the flame-side area of the slats serve to a predetermined outlet cross-section for the fuel gas-air mixture realize. It can be provided that the widening in Project the axial direction of the cable sections on both sides of the lamella. For example, such widening can be achieved by a forming process be generated.
- the lamella to form the widening is provided with a bend at least on its flame-side region.
- the lamella can be at its flame-side area by 180 ° folded over or angled, for example, only by 90 °.
- 1 to 3 are different design variants of slats 10 shown for lamellar burners.
- Fig. 1 shows a lamella 10, which consists of a thin-walled sheet steel blank is made.
- the material thickness of the lamella 10 can be 0.4 to 0.8 mm be.
- In the lamella 10 there is an opening 13 with a circular cross section brought in.
- the opening 13 merges into a spacer element 12.
- This Spacer 12 is collar-shaped and has a cylindrical circumferential inner jacket 12.1, which is coaxial to the central longitudinal axis of the opening 13 is arranged.
- the breakthrough 13 passed into the inner jacket 12.1 via a taper. This rejuvenation serves as a threading aid.
- the lamella 10 can with its breakthrough a line section of a cooling system can be pushed on.
- the free internal cross section the inner shell 12.1 is dimensioned slightly smaller than that External cross section of the line section. So the slat widens 10 in the area of their spacer 12 and is resilient on the Line section clamped. Such a connection can be used thermally conditional expansion of the line section and the lamella 10 compensate.
- FIG. 2 shows a lamella 10 which is essentially identical to FIG. 1 shown.
- lateral widening 14.1 by folding the lamella 10 in its area on the flame side. 3, the widening 14.1 created by a right-angled bevel.
