Abstract
A burner for operating a unit for generating a hot gas consists essentially of at least two hollow partial bodies (,) 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 (,) form tangential air inlet ducts (,) for the inlet flow of combustion air (,) into an internal space (,) prescribed by the partial bodies (,). The burner has at least one fuel nozzle (,). In order to control flow instabilities in the burner, the inside of the burner outlet (,) has a plurality of nozzles (,) along the periphery of the burner outlet (,) for introducing axial vorticity into the flow, the nozzles (,) for injecting air (,) being arranged at an angle to the flow direction (,).
