Burner (), in particular for a vehicle heater (), having an orifice plate () separating an inner combustion region () from an outer region (), wherein a photosensitive sensor () is arranged in the outer region (), wherein at least two separate air inlet openings () are being provided in the orifice plate (), wherein one of the at least two air inlet openings () is additionally formed as a light opening () which also allows light to pass from the inner combustion region () to the photosensitive sensor () that is arranged in the outer region (), wherein the at least two air inlet openings () are being shaped such that the same combustion air quantities flow into the internal combustion region () per unit time, respectively, and wherein the orifice plate () is transparent and/or the light opening () has a shape different from the air inlet openings () that are not formed as light opening such that an illumination area defined by the light opening () is larger than a reference illumination area defined by one of the at least two air inlet openings () that are not formed as light opening ().

Burner with improved orifice plate

An evaporator assembly (), in particular for a fuel-operated vehicle heater (), comprising a pot-like evaporator reception (), an evaporator body () inserted into the pot-like evaporator reception (), a plate-like designed hold-down element (), which is fixed to the evaporator reception () and fixes the evaporator body () in the evaporator reception (), and wherein the plate-like designed hold-down element () has at least one retaining claw (), which has an upper part () on an upper side () of the plate-like designed hold-down element () and a lower part () on a lower side () of the plate-like designed hold-down element (), wherein the upper part () and the lower part () point away from the plate-like designed hold-down element ().

Evaporator unit for a fuel-operated vehicle heater

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).
