FRITZ KIESLER in HAMBURG. Downward directed gas incandescent light burner.

Patented in the German Empire on August 11, 1905.

In the case of incandescent gas burners, namely high-power burners, is often in the burner head a perforated plate made of refractory material and placed under this a wire mesh to allow the flame to penetrate and to prevent the destruction of the network. Such a fireproof, perforated plate with upstream wire mesh is also used in the present, downward-facing incandescent gas burner inserted into the burner head mouth, but the plate is bent towards the inside of the burner head and on . Edge with standing at an angle to the burner center line, preferably in the direction the radius of curvature of the plate running perforations for the outlet or passage of the gas mixture. This curvature of the plate serves as well as with upright burners the well-known, Wire mesh pressed in towards the bottom to create a Bunsen flame that is as elongated as possible produce.

In the drawing, FIG. 1 shows an invert burner head set up according to the invention in longitudinal section and FIG. 2 in a bottom view.

The lower end of the burner head b fastened on or to the burner tube α is effected by a relatively thick, concave plate c which is provided with holes d at the edge for the passage of the gas mixture. The plate c, the attachment of which on the BEZW. in the burner head, e.g. B. by a screw engaging in a transverse web e of the burner head // is made of non-combustible material (e.g. steel, magnesia, soapstone) and not only offers the burner or mixing sieve g upstream a smooth support surface, but also reliably protects it against burning. The fact that the passage openings d , which are relatively long due to the thickness of the plate c , have the effect that the gas mixture only begins to burn at the lower edge de / holes, so that the flame is kept away from the burner screen.

The openings d are arranged so that their center lines are inclined to the center line of the burner at an angle, that is, converge below the burner. The arrangement will advantageously be chosen so that the center lines of the openings d coincide with the radii of curvature of the plate c .

By 'the obliquely inwardly directed openings d it is achieved that the gas-air mixture flows out in downward and inward directed jets which meet or against each other at a certain distance below the plate c and unite to form a bundle.

Such a feeding of the burner, made possible by the inclined arrangement of the outlet channels d and ensured or guaranteed by plate c during the burning, results in a flame that burns downwards with a relatively long flame cone in which the gas light that otherwise occurs with the usual hanging gas light Strive to get to the edge of the

To hit the burner head up, ' so the brief reversal of the flame is prevented.

The new burner therefore delivers with notification that the burner screen has burned through a flame of great luminosity.

Claims (1)

Patent claim: ίο Downwardly directed gas incandescent light burner, characterized in that the bottom of the burner head is terminated by a concave plate (c) made of refractory material, which at the edge with obliquely inwardly inclined outlet channels , preferably running in the direction of the radius of curvature of the plate (c) (d) is provided for the purpose of preventing the burner screen (g) from being burned through and producing an elongated, downward-burning cone of flame. For this purpose ι sheet of drawings.
