Abstract:
1. A swirler arrangement for injecting a fluid into a tubular swirling chamber having an inner surface, the swirler arrangement comprising: a first radial swirler device; a second radial swirler device; and an adapter plate, wherein the swirler arrangement is fixed around an internal circulation zone of the tubular swirling chamber, wherein the first radial swirler device includes a plurality of first vanes, the plurality of first vanes are formed to inject the fluid into the internal circulation zone with a first injecting angle, wherein the second radial swirler device includes a plurality of second vanes, the plurality of second vanes are formed to inject the fluid into the internal circulation zone with a second injecting angle, wherein the first injecting angle and the second injecting angle are defined by an angle between an injecting direction of the fluid and a tangential direction along the inner surface, wherein the first injecting angle and the second injecting angle are smaller than 90°, wherein the first injecting angle and the second infecting angle are different, wherein the first radial swirler device and the second radial swirler device are attached to the adapter plate, and wherein the adapter plate includes a defined thickness for spacing the first radial swirler device and the second radial swirler device, wherein the adapter plate is formed by a circumferential plate with a through-hole, and wherein the through-hole is adapted to a diameter of the tubular combustion chamber.
