摘要： A swirler for creating a swirling fuel/air mix is presented. The swirler has vanes extending radially around a central axis of the swirler and positioned on an annular base. The swirler has mixing channels for mixing the fuel and the air. At least one mixing channel is defined by opposing walls of two adjacent vanes. At least one of the opposing walls includes a primary side injection opening for ejecting a stream of fuel into the mixing channel; and a secondary side injection opening which corresponds to the primary side injection opening and is for ejecting a jet of fuel into the mixing channel. The secondary side injection opening is positioned on the wall such that the jet from the secondary side injection opening creates turbulence, within the mixing channel, in the stream from the primary side injection opening. The turbulence increases mixing of fuel and air.

摘要： The invention relates to a burner (1), comprising an air supply and premix channel (4) having an essentially annular cross-section, through which air and fuel flow during operation, and which is formed of an outer shell (5) and a hub (6). A plurality of swirl blades (7), which extend from the hub (6) to the outer shell (7) in a radial direction and are provided with a deflection surface (11), are arranged in said burner. In a radial outer region of the swirl blades (7), a downstream flow angle (α) to a main flow direction (13) increases at least once and decreases at least once in a radial direction at an outflow end (12) of the deflection surface (11).

摘要： The multiple cone burner (1) comprises a swirl chamber (2) defined by a plurality of wall elements (7). A combination of nozzles at the pressure side, suction side and trailing edge of the wall element (7) are placed for fuel injection. The wall elements (7) define slots (8) between each other which have different widths (w) in consecutive planes (11, 11') in the axial direction; the planes (11, 11') are perpendicular to the central axis (5).
The burner (1) further comprises a lance (3) in the swirl chamber (2), a transition element (22) at the larger end of the swirl chamber (2), and a mixing tube (23) connected to the transition element (22) providing an almost completely circular air passage (24) between the transition element (22) and the mixing tube (23). The passage (24) is arranged to eject a flow through it, substantially parallel to a surface of the mixing tube (23), wherein the axial location of the outlet (29) of the passage (24) and radial gap of the passage (24) are fixed. Spacers are arranged in the passage (24) on the surface of the mixing tube (23) and/or the transition element (22) to avoid eccentricity of the two parts while still allow sliding and air passage. The spacers are axially tilted in order to control the swirl of the purge flow to a desired value.
