Abstract

Bei einem Brenner zum Betrieb eines Aggregates zur Erzeugung eines Heissgases werden im von einer Anzahl Teilkörper (1, 2) gebildeten Innenraum ( 8) Leitkörper (50) angeordnet, welche an den Innenwänden dieser Teilkörper wirken. Diese Leitkörper (50) haben vorzugsweise die Form von Leitschaufeln und sorgen dafür, dass die weitgehend tangential in den Innenraum (8) einströmende Verbrennungsluft (7) in Strömungsrichtung umgelenkt wird. Diese Umlenkung zu einer axialen Komponente der Strömung innerhalb des Innenraumes (8) geschieht allmählich, wobei der Grad von den vorgegebenen Anströmungswinkeln (α, αn) der Leitkörper (50) abhängt. Damit wird eine Maximierung der Mischungsgüte der Verbrennungsluft (7) und eine Verstärkung der Positionsstabilität der Rückströmzone am Brenneraustritt erreicht.

In a burner for operating a unit for generating a hot gas, guide bodies (50) are arranged in the interior (8) formed by a number of part bodies (1, 2), which act on the inner walls of these part bodies. These guide bodies (50) preferably have the shape of guide vanes and ensure that the combustion air (7) flowing largely tangentially into the interior (8) is deflected in the direction of flow. This deflection to an axial component of the flow within the interior (8) takes place gradually, the degree depending on the predetermined flow angles (α, α n ) of the guide bodies (50). This maximizes the mixture quality of the combustion air (7) and strengthens the positional stability of the return flow zone at the burner outlet.
