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.

Abstract: An evaporator burner for a mobile heating device is provided having a combustion chamber, an evaporator accommodation, and an evaporator element for evaporation of liquid fuel. The evaporator element is accommodated in the evaporator accommodation at the side facing the combustion chamber. At the side of the evaporator accommodation facing away from the combustion chamber, the evaporator burner comprises at least one combustion air guide element which is arranged such that a combustion air flow path extending at least along a portion of a base wall of the evaporator accommodation is formed between the combustion air guide element and the base wall of the evaporator accommodation.
