| 摘要 |
The present invention describes a swirler arrangement (100) for injecting a fluid into a tubular swirling chamber (120), which comprises a first radial swirler device (101) and a second radial swirler device (102) and which is adapted for being fixed around an internal circulation zone (105) of the tubular swirling chamber (120). The first radial swirler device (101) comprises first vanes (201) formed to inject the fluid into the internal circulation zone (105) with a first injecting angle (±). The second radial swirler device (102) comprises second vanes (202) formed to inject the fluid into the internal circulation zone (105) with a second injecting angle (²). The first injecting angle (±) and the second injecting angle (²) are defined by an angle between an injecting direction of the fluid and the tangential direction along the inner surface (303) and are smaller than 90°, wherein the first injecting angle (±) and the second injecting angle (²) are different. |
