A burner arrangement (1), for a mobile heater operated with liquid fuel, is provided; having a combustion chamber (2) for converting fuel with combustion air in a flaming combustion, which combustion chamber (2) extends along a longitudinal axis (Z) in a main flow direction (H); a pre-mixing chamber (3), which is arranged fluidicly upstream of the combustion chamber (2), for generating a fuel-combustion air-mixture, which pre-mixing chamber (3) comprises a side wall (4); a fuel evaporation surface (O) arranged in the pre-mixing chamber; a fuel supply (10) for supplying liquid fuel; and a first combustion air supply (6) having a swirl body (7) for supplying a combustion air flow into the pre-mixing chamber (3) with a swirl such that the combustion air is guided along the fuel evaporation surface (O) with a tangential flow component. A neck portion (5) is formed at a transition from the pre-mixing chamber (3) to the combustion chamber (2) at which the flow cross-section abruptly widens in the main flow direction (H).
