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

Burner arrangement for heater

An evaporator arrangement () for evaporating liquid fuel for a mobile fuel-operated heating device, comprising: an evaporator unit () for distributing and evaporating liquid fuel; and at least one fuel supply line () for delivering liquid fuel to the evaporator unit (). The evaporator unit () has at least one first section (B) made of a metal wire mesh ().

Evaporator arrangement

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

A mobile heating device operated with liquid fuel is provided, having: a combustion chamber () comprising a combustion air inlet (), wherein the combustion chamber adjacent to the combustion air inlet () comprises a widening portion () the cross-section of which widens with increasing distance from the combustion air inlet () and in which in operation combustion air and fuel are converted in a flaming combustion; a fuel supply which is arranged such that fuel is supplied into the widening portion (); and an air guide device () being adapted to feed combustion air into the widening portion () with a flow component directed in the circumferential direction such that an axial recirculation region (RB) forms in the widening portion () in which gases flow in the direction towards the combustion air inlet () oppositely to a main flow direction (H). The combustion chamber () is fluidically sectioned into a primary combustion zone (PZ) and a secondary combustion zone (SZ). The primary combustion zone (PZ) comprises the widening portion () and the recirculation region (RB). The secondary combustion zone (SZ) is provided with a secondary combustion air inlet () in such a manner that a higher air-fuel ratio &#x3bb; than in the primary combustion zone (PZ) forms in the secondary combustion zone (SZ).
