Flame tube for a light oil burner

The invention relates to a flame tube for a light oil burner which is used to hold a nozzle assembly and a baffle plate arranged in front of the nozzle of the nozzle assembly and ignition electrodes in the area the nozzle is used as it is used for boiler units for heating living space or the like.

The object of the present invention is to create a flame tube for a light oil burner, the one more economical and more environmentally friendly Allows operation of the burner.

This object is achieved in that the flame tube in the outlet end area for feed channels having hot gases from the combustion chamber, wherein the supply channels on the circumference of the flame tube in the direction are arranged openly distributed to the outlet side of the flame tube.

This allows hot gases from the combustion chamber to add to the fuel-air mixture that comes out of the Flame tube emerges with the formation of the flame, is admixed again, whereby firstly a very hot flame results, secondly better combustion takes place, thirdly the CO and nitrogen oxide content in the exhaust gas reduced and thus the profitability and conversion. World friendliness of the light oil burner is improved.

Further refinements of the invention can be found in the following description and the subclaims refer to.

The invention is described below using an exemplary embodiment shown in the accompanying drawings explained in more detail.

Fig. 1 shows a flame tube for a light oil |

burner in axial section and

Fig. 2 shows the front end of the flame tube of Fig. 1 from the outlet side seen. §

The flame tube 1 _; which protrudes into the combustion chamber of the boiler of the corresponding boiler system when installed, serves to accommodate a nozzle assembly and a baffle plate arranged in front of the nozzle of the nozzle assembly as well as ignition electrodes in the area of the nozzle (these §

Internals are not shown). The baffle plate is in the area of the constriction 2 of the flame tube 1 arranged.

There are bulges in the outlet end area of the flame tube 1 in front of the baffle plate 3, which are gill-like in that the flame tube 1 is provided with a series of incisions is, the bulges 3 by pressing an approximately semicircular portion of the Flame tube limited by the respective incision inwardly with the formation of the gill-like bulge 3 are trained.

On the outside of the flame tube 1 there is a ring 4 which has a conical inner surface 5, which is arranged adjacent to the bulges 3 and with these ■ supply channels 6 for hot exhaust gases from the combustion chamber to the fuel-air mixture that emerges from the flame tube 1 during operation, forms. The conical inner surface 5 of the ring 4 forms with the flame tube 1 an annular one Entry gap for the gas from the combustion chamber, 'that through to the outlet side of the flame tube 1 protruding bulges 3 which are open. The feed channels 6 run essentially axially and are distributed on the inner circumference of the flame tube 1 in the direction of the outlet side of the flame tube 1 opening arranged. Due to the fuel-air mixture flowing through the flame tube 1, during operation hot gases from the combustion chamber through the supply channels 6 into the flame tube 1 and thus into the mixture sucked in. For this purpose, the flame tube 1 must protrude so far into the combustion chamber of the boiler system, that hot gas can flow into the supply channels 6 from the combustion chamber.
