Abstract (en)
[origin: EP0833105A2] The pre-mixer burner has a torsionally stabilised inner chamber (18) with an inner body (13) running conically in the flow direction. A mixer pipe (21) is connected downstream of the inner chamber (18) and changes through a cross-sectional jump into a burner chamber (31). A torsional flow (23) flows through the mixer pipe. The cross-sectional jump is formed by a front wall (25) and a reverse flow zone (32) can be produced in the plane of the cross-sectional jump. At least one fuel lance (14) enclosed by an air stream passes preferably centrally through the inner body of the inner chamber with the burner nozzle (17) set in the tip area of the inner body.
