Abstract (en)
[origin: EP0538594A2] Arranged as swirl bodies at an angle of incidence ( beta ) of more than 45 DEG at the discharge cone (5) of a burner pipe (1) are at least six guide vanes (6). A division of the secondary air into individual swirl jets takes place, with a great acceleration effect. As a result, a greater waste gas recirculation is caused at the flame envelope region and the flame surface area is increased. The NOx formation is reduced. <IMAGE>
