Abstract

A burner for generating a hot gas including at least two hollow partial bodies stacked inside each other in a downstream air flow direction. The center axes of the hollow bodies extend offset to each other such that burner slits formed by adjoining walls of the partial bodies form tangential air inlet channels for an inflow of combustion air into an inside chamber defined by the partial bodies. The hollow bodies are provided with a plurality of baffles projecting into the downstream air flow. The plurality of baffles add an axial turbulence force to the air flow.
