Abstract
A burner arrangement (), for a mobile heater operated with liquid fuel, is provided; having a combustion chamber () for converting fuel with combustion air in a flaming combustion, which combustion chamber () extends along a longitudinal axis (Z) in a main flow direction (H); a pre-mixing chamber (), which is arranged fluidicly upstream of the combustion chamber (), for generating a fuel-combustion air-mixture, which pre-mixing chamber () comprises a side wall (); a fuel evaporation surface (O) arranged in the pre-mixing chamber; a fuel supply () for supplying liquid fuel; and a first combustion air supply () having a swirl body () for supplying a combustion air flow into the pre-mixing chamber () with a swirl such that the combustion air is guided along the fuel evaporation surface (O) with a tangential flow component. A neck portion () is formed at a transition from the pre-mixing chamber () to the combustion chamber () at which the flow cross-section abruptly widens in the main flow direction (H).
