The invention relates to an in-line burner for a gas « Heated device with a gas distribution chamber composed of two half-shells, on the top of which combustion openings are formed are.

Starting from such a series burner, as it is described in DE-PS 36 22 763, it imagines the « lying invention for the task of making the half-shells as simple and robust as possible so that they are in constant sequence Main and auxiliary combustion openings lined up alternately form, which, matched to their size, consistently have the same specific gas throughput.

According to the invention limit the two half-shells in the Above the mixture distribution chamber, both elongated profiles of Hauptbrenn = locally tangent to each other openings as well as shorter profiles of auxiliary combustion openings in between.

As a result, a pair of such half-shells joined together results in each case without further action and without the aid of additional ' Licher complex components a desirably compact and operationally reliable unit, with only one single-minded Dimensioning of the profile of these half-shells based on the required output of the in-line burner, taking into account the locally varying factors, such as gas pressure, calorific value, etc., can be taken into account. Alone by a purposeful professional = lation of the half-shells can be that throttling of the gas supply

to reach the more or less large gas outlet openings, which is necessary in order to let the gas exit from all openings with - approximately the same pressure.

Exemplary embodiments of the subject matter of the invention are in Drawings illustrated / u.zw. demonstrate

Fig.l the top view of a series burner, 2 shows a partial plan view on a larger scale, 3 shows a cross section through a main combustion opening, as well as

Fig. 4 and 5 cross sections through auxiliary combustion openings in two types of execution.

The in-line burner according to the invention consists of the two profiled half-shells 1 which are connected to one another in sections and which enclose a transverse gas distribution chamber 2 and are connected to one another via edge flanges 3.

In the areas 4, the two half-shells 1 touch each other locally and are also connected to each other, where they have 4 gas passage openings between these areas limit.

Such a unit formed by half-shells 1 has flanges and is supplied via gas supply (not shown) directions supplied with gas.

In the area above the gas distributors in chamber 2 delimit the two half-shells between the tangent areas 4, both elongated profiles, in plan view rectangular shaped profiles of main combustion openings 6 as well as shorter, squat ones in between, in the top = sees round profiles of auxiliary combustion openings 7.

The profile delimited jointly by the two half-shells 1 goes from the wider lower region of the gas distributor ^{9 to} chamber 6 with a conical gradation 8 in the narrower upper region of the main combustion opening 6 (FIG. 3).

The same applies in principle to the profile of the half-shell » pair in the area of the auxiliary combustion openings 7 (Fig. 4), but the flanks of the series burner point in these areas Additional combustion openings 9 open to the side open and then narrow once more above these additional combustion openings Combustion openings 9 with a gradation 10 to the upwardly directed auxiliary combustion openings 7.

According to a variant illustrated in FIG. 5, under = half of the laterally open combustion openings 9 locally one Constriction (constriction) 11 may be provided.

With a targeted dimensioning of the mentioned graduations 8 and 10, which act as baffle plates, as well as the constriction 11 can, thanks to the purposeful profiling of the half-shells, without any further action, simply by the purposeful throttling Profiling of the half-shells, in the area above the gas distributor = chamber 2, an absolutely uniform ver = division of the gas pressure via the more or less large outlet openings 6 or 7. This will a quick and reliable over-ignition of the burner is guaranteed and the risk of occurrence of Deflagrations prevented.
