Abstract: An evaporator burner (100) for a mobile heating unit which is operated using liquid fuel is provided, said evaporator burner having: a mixture preparation region (2) for the mixing of fuel with combustion air to form a fuel-air mixture; a fuel feed (1) for feeding liquid fuel to the mixture preparation region (2); a combustion air feed (B) for feeding combustion air to the mixture preparation region (2); at least one evaporation surface (8) to which the liquid fuel is fed and which serves for the evaporation of the liquid fuel; a conversion region (3), positioned downstream of the mixture preparation region (2) in terms of flow, for the conversion of the fuel-air mixture into combustion exhaust gases (A) with a release of heat; and an exhaust-gas recirculation means (10; 210) for the recirculation of combustion exhaust gases (A) into the mixture preparation region (2).

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: The invention relates to an evaporator burner (100) for a mobile heating device operated with liquid fuel, comprising: a mixture-preparing region (2) for mixing fuel with combustion air to form an air-fuel mixture, a fuel supply (1) for supplying liquid fuel to the mixture-preparing region (2), a combustion-air supply (B) for supplying combustion air to the mixture-preparing region (2), a reaction region (3) arranged downstream of the mixture-preparing region (2) for reacting the air-fuel mixture, heat thus being released, and an evaporator body (9) for evaporating the liquid fuel, which evaporator body extends in an axial direction in the mixture-preparing region (2) at a distance from a side wall and has an outer peripheral surface designed as a fuel-evaporating surface, which outer peripheral surface is arranged in such a way that the supplied combustion air flows around the outer peripheral surface.
