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).
