Abstract:
1. Apparatus for rotating heated air in a chamber, the apparatus having a gas inlet opening and a gas outlet opening, wherein the gas inlet opening and a heat source are located in a lower area of the chamber and the gas outlet opening is located in an upper region of the chamber so that an ascending gas flow may be generated in the chamber, wherein the heat source is located in the center of the chamber and the chamber tapers inwardly in a hyperbolic manner from bottom to the top and there is at least one gas inlet channel or nozzle formed so that inflowing gas flows therethrough in a directed manner along a directional vector into the lower area of the chamber such that a substantial component of the direction vector projects along an inner wall of the chamber and follows an at least approximately circular path along the inner wall in a common rotational sense around the heat source and then is drawn upwardly by a draw of the upwardly flowing heated gases along an approximately spiral path thereby rotating rising heated air from the heat source which passes through the gas outlet opening.
