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.
