DE450535C - Tube-shaped gas burner - Google Patents

Description

Tubular gas burner. For gas heating of baking chambers, Drying and the like, special burners are required which are in the form of more or have less long pipes and offer the possibility of simple manufacture must, over the entire length of the burner, exactly uniform, reliable and to ensure adjustable flame depending on the intended heating.

In the previously known burners of this type, this was z. B. thereby tries to achieve that one in a longitudinal slot that get over extended the entire length of the burner tube, inserted a strip of corrugated iron or the like, in order to divide the slot into many openings. This has the disadvantage that these openings are not exactly even and that one cannot hold it in one's hand has to keep them in the desired, precisely determinable size. When these openings z. B. turn out to be too large at individual points, the exit speed ' from the burner less than the ignition speed of the gas and the flame strikes return.

In the gas burner according to the present invention, these errors are avoided, because with him the possibility is given, the exit cross-sections exactly the same to make great.

An embodiment of the new burner is shown in the drawing.

Fig. I shows part of the burner in longitudinal section, Fig.2 shows a Cross-section, Fig.3 the whole burner in a 'longitudinal section on a smaller scale.

The burner consists of a gas tube i, which is closed at one end while the gas-air mixture is fed to it at the other open end. That The gas-air mixture then comes over the entire length of the burner tube i milled slot for combustion.

The subdivision of this slot to achieve more precise, smaller openings now happens in the following way: A wire is helically around a flat iron 2 3 wrapped with a wire size and pitch that have been precisely determined beforehand. This flat iron - with the tightly wound wire 3 is between two slightly wider flat iron guide 4 saved by means of countersunk rivets 5. The finished strip is then riveted together inserted into the slot of the burner tube i, which is fastened with rivets or screws 6, on which the strip rests, is pulled together tightly. Thereby are expedient the rivet or screw holes of the flat iron core 2 are designed as elongated slots, to allow displacements of the flat bars 2 and 4 as a result of different thermal expansion.

By using thinner or thicker wire 3 and by winding it up with a smaller or larger slope on the flat iron 2 one has @es in an easier way Way in hand, the burner openings of exactly the same and specific size to manufacture. It is advisable to use flat wire as the wire, as it is larger Cross-section than round wire and tears less when winding, even later burns less easily when burning.

Claims (4)

PATENT REPRESENTATION i. Gasbremier in tubular form with burner slots, characterized in that gas outlet openings on the one hand through a slot in the burner tube (i), on the other hand by a helically wound onto a core (2) Wire (3) of wire thickness and pitch determined by the size of the torch openings are accomplished. 2. Gas burner according to claim i, characterized by the use of flat wire. 3. Gas burner according to claim i and 2, characterized in that the core (2) carrying the helically wound wire by means of rivets (5), screws o Burner slot is used. 4. Gas burner according to claim 1, 2 and 3, characterized in that the rivet or screw holes of the core (2) are designed as elongated slots, so that the diversity the thermal expansion between the inner core (2) and the two outer guide flat irons (4) is taken into account.
