    • The subject of the invention is a method as well as an apparatus for suppressing flow vortices within a turbo power machine with a premix burner, into which fuel and air are introduced for mixing, which then leave the burner downstream along its burner axis in the form of a fuel/air mixture through a burner outlet and flow into a combustor located downstream from the burner in the flow direction of the fuel/air mixture. The invention is based on the basic idea of—for the fluid-mechanical stabilization of a premix burner, into which at least one combustion air stream (5) is fed tangentially into a burner chamber (6) and is mixed with an injected gaseous and/or liquid fuel (7;8) while forming a swirl flow (9) oriented coaxially to the burner axis and induces a reverse flow zone (15) at a change in the cross-section on a burner mouth (14), that is used during the operation of the burner to stabilize the flame—increasingly, radially deforming the swirl flow (9) within the burner chamber (6) in the direction of the burner mouth (14) and let it enter the combustor (12) in a non-rotation-symmetrical flow cross-section, whereby this deformation is created by reducing the free flow cross-section (18) of the burner chamber (6). The fuel/air mixture flows into the combustor with a non-rotation-symmetrical flow cross-section.
    • 本发明的主题是一种方法以及用于在具有预混合燃烧器的涡轮动力机械中抑制流动涡流的装置,燃料和空气被引入燃料和空气中用于混合,然后将燃烧器沿其燃烧器轴向下留下 的燃料/空气混合物通过燃烧器出口流入燃料/空气混合物的流动方向上的燃烧器下游的燃烧器。 本发明基于用于预混合燃烧器的流体 - 机械稳定化的基本思想,其中至少一个燃烧空气流(5)被切向地进料到燃烧器室(6)中并与注入的气体和 /或液体燃料(7; 8),同时形成与燃烧器轴线同轴定向的涡流(9),并且在燃烧器口(14)上的横截面变化时引起反向流动区(15),也就是说 在燃烧器操作期间使用以使燃烧器口(14)的方向上的火焰逐渐变大,使得燃烧器室(6)内的涡流(9)径向变形,并使其进入燃烧器(12) 非旋转对称的流动横截面,由此通过减小燃烧室(6)的自由流动横截面(18)而产生这种变形。 燃料/空气混合物以非旋转对称的流动横截面流入燃烧器。

    • A burner for operating a unit for generating a hot gas consists essentially of at least two hollow partial bodies (1, 2) which are interleaved in the flow direction and whose center lines extend offset relative to one another in such a way that adjacent walls of the partial bodies (1,2) form tangential air inlet ducts (5, 6) for the inlet flow of combustion air (7) into an internal space (8) prescribed by the partial bodies (1, 2). The burner has at least one fuel nozzle (11). In order to control flow instabilities in the burner, the inside of the burner outlet (17) has a plurality of nozzles (32) along the periphery of the burner outlet (17) for introducing axial vorticity into the flow, the nozzles (32) for injecting air (34) being arranged at an angle to the flow direction (30).
    • 用于操作用于产生热气体的单元的燃烧器基本上由至少两个在流动方向上交错并且其中心线相对于彼此延伸偏移的中空部分体(1,2)构成,使得相邻的壁 部分主体(1,2)形成用于燃烧空气(7)入口流入由部分主体(1,2)规定的内部空间(8)的切向空气入口管道(5,6)。 燃烧器具有至少一个燃料喷嘴(11)。 为了控制燃烧器中的流动不稳定性,燃烧器出口(17)的内部具有沿着燃烧器出口(17)的周边的多个喷嘴(32),用于将轴向涡流引入流中,喷嘴(32) 用于喷射与流动方向(30)成一定角度排列的空气(34)。
