A device for producing a rotating flow in a rectangular flow duct which has a flue-gas outlet of an incineration plant, in particular of a garbage incineration plant, and a transition region from a combustion chamber of the incineration plant to the flue-gas outlet. First wall sections on two opposite walls define the flow duct and have a wall width b. The first wall sections have a length lof at least approximately 0.4b&#x3c;0.8b. These first wall sections, with the center longitudinal axis of the flow duct as axis of symmetry, are centrosymmetrically opposite one another and are defined on the one side by the adjacent wall. In the first wall sections, first nozzles for media which can be emitted in the form of a jet are oriented in a row in an injection plane in such a way that they inject a jet into the injection plane, the angle lying in the injection plane between the wall and an injected jet being at least approximately 90&#xb0;.

The distribution-pressurized natural gas is supplied via a conduit arranged in the piston of an electrovalve in a nozzle of which the outlet leads to a cone which provides, with the nozzle, a ring-shaped opening which, connected to the atmosphere, acts as a secondary nozzle for injecting air into the gas flow. The cone is followed by a cylindrical element then by an abrupt widening section which opens into a heat exchanger which is in contact with a substrate impregnated with a catalytic material which oxidizes fuel gas. A small amount of air is sucked up by the widening and mixed with the gas. This mixture is then treated in the exchanger up to the transformation temperature of the sulphur-containing compound and the sulphur is then oxidized.
