    The method entails passing impure gases from an incineration plant such as a destructor, process furnace, crematory furnace or heating boiler, through a burner in an afterburner where through enforced mixture with combustion gas they undergo complete combustion. The combustion gas, depending on the composition of the flue gases, may consist of air or oxygen or either mixed with liquid petroleum gas. …<??>In the device for implementation of the method the flue gases and the combustion gas are introduced into a burner (10, 44) which blows the gas mixture into a flame bowl (3, 52) where temperatures in the 1500 - 2000 DEG C range can be achieved. In one version of the invention the burner (44) produces a conical basketshaped flame in which the flue gases undergo complete combustion.

    flame. The central passage 34 of the burner 33 is provided to feed gases from the
    previous kilns. Hole 35 is located on the inclined high-axis axis of the burner 33, and through them gas mixture flows with air for combustion in a large number of flame plumes. The taper of the basket-shaped conic flame is determined by the angle at which the holes are drilled. On the bottom 36 of the afterburning chamber 29, there is an insert sleeve 37 with holes 38 around its bottom edge. Hole: and 38 are connected by a collapsing support cavity and open access to exit 39, passing through under. On the inside of the support there are support shoulders 40, on which the flame bowl 41 is supported, made of refractory material and having a configuration of almost a half sphere. Flame bowl 41 is made with the possibility of vertical movement and provides for the regulation of the flame.
    A few shoulders at the back of the central passage 34, the holes are drilled at a sharp angle to the burn. The passage through the heating device 16, the gases can be heated to a high temperature exceeding 1000 ° C, and enter the annular space 25, from where they are directed through the holes 26 to the peak 17 of the burner 10. The holes 26 direct the treated gases in such a way that in order to force them to rotate around the nozzle 18. Their rotation is also enhanced by the tangential exit of the combustion gas from the nozzles 18, thereby achieving a good mixing of the gases. Air, oxygen, or fuel can be used as a combustion gas, which is determined by the composition of the exhaust gases to be afterburning. In the nozzle 11, the gases react, and their temperature rises, and through the 20 flame tube 9 they emerge as a uniform flame, which is released into the flame bowl 3. The flame hits the hemispherical end 4 of the flame bowl, which reflects 25 180 ° and rushes into an annular gap formed by the outer part of the flame tube 9 and the cylindrical surface of the body 5 of the flame and 3. In the annular gap, the flames burn through and the gases rush through the openings 6 into the afterburner 1. From the afterburning chamber, the completely burned out flue gases are removed through the outlet pipe 27, around which the heat-treatment device 28 is located.
    In an embodiment of the device (Fig. 2), the gases to be treated are fed through the central passage 34 40 of the burner 33 into the afterburning chamber 29. B. The same burner supplies gases that provide combustion (air, oxygen, or fuel), which flow in numerous streams from the openings 35 of the burner 45 in such a way that, when combined, form a conical basket-shaped flame. The flame taper is determined by the angle at which the holes 35 are drilled in the burner 33. A co-50 basket-shaped flame strikes the flame bowl 41 and is reflected from it, while the flame is more twisted inward towards the center, where the gases to be processed quickly mix with combustion gases, and completely burned in a fiery basket. Since the flaming bowl 41 has the ability to move vertically, a flaming basket of various sizes can be formed, which makes it possible to adjust the ratio between the gas velocity in the central passage 34 and the gas release rate through the flaming basket.
    The proposed design of the device provides an improvement in the mixture formation and thus the complete afterburning, which increases the efficiency of the afterburning process of the exhaust gases.
