Evaporator burner for a mobile heating unit operated using liquid fuel

An evaporator burner for a mobile heating device operated with liquid fuel, said burner comprising:

• a mixture preparation region mixing fuel with combustion air to form a fuel-air mixture;
• a fuel supply supplying liquid fuel to the mixture preparation region;
• a combustion-air supply supplying combustion air to the mixture preparation region;
• at least one evaporation surface to which the liquid fuel is supplied for evaporation of the liquid fuel;
• a reaction region downstream of the mixture preparation region in terms of flow and which serves for the reaction of the fuel-air mixture to form combustion exhaust gases with a release of heat;
• and
• an exhaust-gas recirculation arrangement recirculating combustion exhaust gases into the mixture preparation region;
• wherein an axial body extends in the mixture preparation region along a longitudinal axis of the evaporator burner so as to be spaced apart from a side wall of said mixture preparation region, and
• wherein the axial body has an internal cavity which is open toward the reaction region and from which at least one exhaust-gas outlet opening extends to the mixture preparation region such that combustion exhaust gases are recirculated through the axial body to the mixture preparation region.
