Patent ID: 8096701

Claim:
A method of mixing at least one gaseous fluid stream with a large gas stream, including the steps of: directing the large gas stream against at least one disk-shaped mixer element on an inlet or windward side thereof, wherein said at least one mixer element is inclined at an angle counter to the direction of flow of the large gas stream, and wherein eddy-type whirls are adapted to form at said at least one mixer element; and guiding the gaseous fluid stream essentially to the center of an impact surface associated with a discharge or lee side of said at least one disk-shaped mixer element, wherein the gaseous fluid stream is admixed with the large gas stream downstream of said at least one mixer element, and wherein the gaseous fluid stream is guided essentially perpendicularly onto the center of the impact surface on the discharge side of said at least one mixer element such that the gaseous fluid is distributed over the entire discharge side of the at least one mixer element from the center thereof and is incorporated across the entire whirl system formed at a peripheral edge of said at least one mixer element.
