Abstract
The invention relates to a device (10) and a method for rotating a flame and/or a plume of smoke, arranged with a heat source (36) in a chamber (16) with at least one gas inlet opening (24, 26, 30) and a gas outlet opening (32). The gas inlet opening (24, 26, 30) and the heat source (36) are located in a lower area (12, 20′) of the chamber (16). The gas outlet opening (32) is located in an upper region (14) of the chamber (1.6). In this way, an ascending gas flow may be generated in the chamber (16). At least one gas inlet channel or nozzle (24, 26, 30, 40) is adapted to direct inflowing gas therethrough into the lower area (12, 20′) of the chamber (16) approximately along an inner wall of the chamber about an at least approximately circular path following along the inner wall in the same rotational sense around the heat source and then is drawn upwardly by a draw of the upwardly flowing heated gases though the gas outlet opening (32). A flame or smoke plume inside the chamber (16) can thereby be placed into a rotary motion.
