In an apparatus for setting the outflow direction, in particular of a swirl, of air and/or burnable gas in a burner for the combustion of powdery or fine-grained, liquid and/or gaseous fuels, in particularly for rotary tubular kilns, comprising at least one primary air duct (1) and at least one jet nozzle (2), the primary air duct (1) has at least one disk set (8) comprising a plurality of parallel disks (9), wherein the disks (9) are mounted so they can be rotated about a common axis (11) and/or displaced relative to each other and in the main position have at least one first group of mutually aligned recesses (10), which together form a duct (12), wherein the duct (12) has a course that deviates from the main position, in particular an inclined and/or curved, particularly a helical course, when the disks (9) are successively rotated or displaced relative to each other compared to the main position. An adjusting apparatus is provided for rotating or displacing the disks (9). |
