摘要： 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.

摘要： 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).

摘要： A burner for generating a hot gas including at least two hollow partial bodies stacked inside each other in a downstream air flow direction. The center axes of the hollow bodies extend offset to each other such that burner slits formed by adjoining walls of the partial bodies form tangential air inlet channels for an inflow of combustion air into an inside chamber defined by the partial bodies.
