Natural gas burner

The furnace "relates to a natural gas burner with a perforated disc, from which the gas-air mixture formed after the supply of compressed air emerges and burns «The well-known Burners of this type have so far not been used for natural gas, but for town gas, but are not suitable for natural gas, because of the high methane content of natural gas and its low Ignition speed lead to the! Flame from the Perforated disc lifts off »Also requires the combustion of Natural gas has a higher proportion of air in the gas mixture, and the mixing of natural gas and air is older when it is used Burner insufficient »

The hiring consists in the fact that in the burner housing before outer perforated disk at a distance one or more inner perforated disks are arranged, the holes of all perforated disks are offset against each other "

The advantage of the innovation is that between the

spaced perforated disks one or more mixing and Relaxation chambers are formed into which the emerging from the perforated disk in front of the chamber in question The gas-air mixture expands and mixes before it passes through the holes located behind this chamber Perforated disc escapes. Mixing is promoted by the fact that the holes of the perforated disks against one another are offset. In addition, the arrangement of the inner perforated disks and the formation of the chambers result in a reduction achieved the exit speed of the gas-air mixture from the outer perforated disk, so that a lift-off the flame from the outer perforated disc is avoided.

The outer perforated disc is advantageously surrounded by a protruding Yfail strand, which increases the stability of the flame is increased.

The bead is advantageous from the protruding hand formed of the housing, in which the outer perforated disc is embedded.

A simple construction of the burner results from the fact that the perforated disks are secured by an intermediate ring or by means of an intermediate ring rings, the outer diameter of which corresponds to that of the perforated disks are firmly connected to one another to form a unit and this unit is pushed into the housing and fastened therein.

in the drawing the innovation "is for example and shown schematically «They show: - ■ ■."

1 shows a section through a burner, FIG. 2 shows a plan view of FIG. 1.

The housing 1 of the burner "consists of a hollow cylinder, one end of which is threaded 2 -that the Connect the housing to the natural gas air supply line. In the housing 1 there are several perforated disks at a distance arranged from each other. The outer perforated disk 3, above which the gas-air mixture burns, is recessed in the Housing 1 so that it is from the top of the housing is surmounted, which forms a beaded edge that secures the stability of the flame 4-.

An inner perforated disk 5 is at a distance from the outer one Orifice plate 3 arranged so that-. between the two perforated disks a mixing and expansion chamber is formed. Instead of an inner perforated disk 5, several can be provided at a distance from one another.

The holes 7 of the outer perforated disk 3 are offset from the holes 6 of the inner perforated disk 5, so that the mixing of the gas-air mixture in the "mixing chamber is increased. - '..'." ...: . ' . '

The perforated disks 5 and 5 are supported by an intermediate ring 8, the outer diameter of which corresponds to that of the perforated disks, firmly connected to one another »This unity is pushed into the burner housing 1 and in its position secured by a screw 9. If several inner perforated disks are used, these are also used "from intermediate rings with the outer perforated disk to one Unity connected.
