Claim:
A thermal post-combustion device comprising a burner, the burner having a combustion nozzle with a substantially hollow-cylindrical base member at least virtually closed at one end by a cover and to which fuel gas is supplied axially at a particular pressure, which gas flows out radially via a plurality of main discharge openings, wherein the main discharge openings are arranged at such a radial distance from the axis of the base member and exhibit such a cross-section that, at the particular pressure of the supplied fuel gas, individual flames form at the main discharge openings which substantially do not overlap; wherein at least one small-area passage opening is provided in at least one of the cover and in the region of the base member close to the cover, wherein the total area of all the small-area passage openings in at least one of the cover and the base member is less than the total area of all the main discharge openings.
