Abstract: A burner arrangement (1), for a mobile heater operated with liquid fuel, is provided; having a combustion chamber (2) for converting fuel with combustion air in a flaming combustion, which combustion chamber (2) extends along a longitudinal axis (Z) in a main flow direction (H); a pre-mixing chamber (3), which is arranged fluidicly upstream of the combustion chamber (2), for generating a fuel-combustion air-mixture, which pre-mixing chamber (3) comprises a side wall (4); a fuel evaporation surface (O) arranged in the pre-mixing chamber; a fuel supply (10) for supplying liquid fuel; and a first combustion air supply (6) having a swirl body (7) for supplying a combustion air flow into the pre-mixing chamber (3) with a swirl such that the combustion air is guided along the fuel evaporation surface (O) with a tangential flow component. A neck portion (5) is formed at a transition from the pre-mixing chamber (3) to the combustion chamber (2) at which the flow cross-section abruptly widens in the main flow direction (H).

Abstract: The invention relates to an evaporator burner (1; 101) for a mobile heating device, comprising: a combustion chamber (3), a fuel feed line (4) for feeding liquid fuel, and an evaporator for evaporating fed fuel. The evaporator has a support body (6; 106) made of a nonporous material, comprising a fuel preparation surface (6a; 106a) which faces the combustion chamber (3) and which comes into contact with the liquid fuel. A surface structuring (11) with a plurality of depressions (11a) and elevations (11b) is introduced into the fuel preparation surface (6a; 106a) and/or into a support body (6; 106) rear face (6b; 106b) facing away from the fuel preparation surface.
