With maximum discharge nozzle - per unit of time, the spindle-shaped fire mines are too long for most combustion chambers and lead to a too high temperature of the gases leaving the combustion chamber, while with minimal discharge per unit of time, the toireiteii and short flames take the lead the Brennkasaisr overheat and you can hardly avoid ά · <3 particles from unverbr 'nntem fuel to the "Jeitenwände of the combustion chambers are gescnleudert. ^:

As is known per se, the outer chamber is an axially movable, cylindrical Verbreiniüngöluftschieber etuf, which brings adjustable and movable air guide flaps into effect when opening and with which the air entering the cylinder corrugation and the inner chamber surrounding the inner chamber can be metered.

These two flap or slide valve arrangements can be separated from land or mechanically or also to the perfect one Automation of the burner can be operated, for example, with a few servo-Kotor, which by means of a triple curling with an adjustable profile on the Pulp dosing beer supply line and the two flap or slide arrangements acts.

, 7ci.ti.re abandonment, features and advantages of the invention result from the following description of a preferred embodiment example b of a burner according to the invention, which does not serve to delimit the concept of the invention, reference being made to the accompanying drawings, in which the flame shapes that can be generated with the burner according to the invention are shown.

? ig. 1 shows an axial smock section through a burner H 'according to the invention,

Pig. 2 in an axial direction schematically in

in full lines a small, spindle-shaped flame and in broken lines a medium one spindle-shaped flame and

FIG. 3 in a representation corresponding to FIG

a broad flame.

The burner has two concentrically arranged chambers, which have the following parts in common:

a fuel injector 1 with mechanical powder ■

2C with continuous operation, their supply and return lines formed by two outer tubes 2 and 5;

an electrical high-voltage arc ignition device consisting of electrodes 4 »insulators 5 and centering bearings

2t> consists of a flame plate 7 which is firmly connected to a sleeve 8 which is brought into a certain position and can then be fixed, for example with a screw, on the central tube 9 of the inner chamber to generate the spindle-shaped flame.

The central tube 9 »which is closed with a cover 10, has an air inlet 11 with an opening 12. In this opening 12 of the inner chamber is a small one

Flap 13 is arranged, which is pivotable about its axis H. and with which the entering into the inner chamber ■ - air can be regulated. The setting of this little flap 13 can be done mechanically, for example by means of a servo-i-i-iotor, not shown, which does not act on a acts with an adjustable profile.

The outer chamber determined by the spread of the flame, which is mounted concentrically around the inner chamber, has a crane ring 15, which is not shown with Traverses or tie rods on a solid cylindrical Housing Ib is attached »This housing 1t. lU3t the air flow to air inlet 11 and also has a circumferential air inlet 17 which is opened to a greater or lesser extent by means of a cylinder slide 18 can be used to increase the air flow in the outer chamber steer. The slide 18 is movable in the axial direction and cannot mechanically, for example, with one Servo-Iiotar shown to be operated on a not shown crouching with adjustable profile eii: - acts; When it opens, the slide 18 brings a Ansahl von Luftleitflügeln 19 sur v / irk that in the air inlet 17 are arranged. This air guide 19 εϊηα movable and adjustable about its axis 20, these axes 20 on a circle around the center axis of the housing 1i. and the crane ring 15 are arranged. Am somehow designed housing 21 of suitable volume through which the combustion air passes through and has a rear wall 22, is around the housing 1o and the crown ring 15 the outer chamber arranged, the housing 21 on the side of the rim ring 15 with a ring seal 24 press-fitting ring 23 is sealed.
