Abstract

The secondary air jets (11) that are arranged within the combustion space (5) consist of an outer casing (12), an inner casing (13), and a flange (14) that connects the two casings to each other, the flange (14) crossing the inner casing (13) and being rigidly connected with this, whereas the outer casing (12) is so connected to the flange that is of greater diameter than the outer casing (12) that slot-type jets (15) are left between the face side of the outer casing (12) and the flange (14), these jets making it possible to expel air parallel to the defining wall and essentially perpendicular to the axis of the jets.
