Abstract: A method and a device for the distribution of gas. The method includes the steps of transferring the gas into a swirl chamber through an inlet section positioned tangentially to the swirl chamber, swirling the gas in the swirl chamber by passage through a number of equally displaced bent vanes, the surface of the upstream part of the vanes lying in a plane perpendicular to the swirl chamber's axis, the downstream part of the vanes being parallel to the swirl chamber's axis, and the vanes extending radially outward, and passing the gas through an outlet section positioned downstream the swirl chamber.
