The invention relates to an evaporator burner () for a mobile heating device operated with liquid fuel, comprising: a mixture-preparing region () for mixing fuel with combustion air to form an air-fuel mixture, a fuel supply () for supplying liquid fuel to the mixture-preparing region (), a combustion-air supply (B) for supplying combustion air to the mixture-preparing region (), a reaction region () arranged downstream of the mixture-preparing region () for reacting the air-fuel mixture, heat thus being released, and an evaporator body () for evaporating the liquid fuel, which evaporator body extends in an axial direction in the mixture-preparing region () 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.

Evaporator burner for a mobile heating device operated with liquid fuel

An evaporator burner arrangement () for a mobile heater operated with liquid fuel having: a mixture preparation region () for generating a fuel-air-mixture, a fuel evaporation surface () arranged in the mixture preparation region () for evaporating the liquid fuel, a combustion air supply (B) for supplying combustion air to the mixture preparation region (), a fuel supply () for supplying liquid fuel to the fuel evaporation surface (), a conversion region () being arranged fluidically downstream of the mixture preparation region () for converting the fuel-air mixture in order to release heat, and a heat conductor body () extending spaced from a sidewall () of the mixture preparation region () through the mixture preparation region () to the conversion region () for feeding-back heat from the conversion region () to the mixture preparation region () by thermal conductance

Evaporator burner arrangement for a mobile heater operated with liquid fuel

An evaporator burner () for a mobile heating unit which is operated using liquid fuel is provided, said evaporator burner having: a mixture preparation region () for the mixing of fuel with combustion air to form a fuel-air mixture; a fuel feed () for feeding liquid fuel to the mixture preparation region (); a combustion air feed (B) for feeding combustion air to the mixture preparation region (); at least one evaporation surface () to which the liquid fuel is fed and which serves for the evaporation of the liquid fuel; a conversion region (), positioned downstream of the mixture preparation region () 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 () for the recirculation of combustion exhaust gases (A) into the mixture preparation region ().

Evaporator burner for a mobile heating unit operated using liquid fuel

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