摘要

The invention relates to a flow-directing insert (28, 130, 131, 132, 133, 134, 135, 136) for a heating device (2) having an evaporator burner (4), wherein: the evaporator burner (4) has a fan chamber or combustion air pre-chamber (20), an evaporator holder (10) and a combustion chamber (8); the evaporator holder (10) has a base wall (26) and a circumferential wall (30) with at least two combustion air passage openings (22) to direct combustion air out of the fan chamber or combustion air pre-chamber (20) initially along an exterior side of the evaporator holder (10) through the combustion air passage openings (22) into the combustion chamber (8); the flow-directing insert (28, 130, 131, 132, 133, 134, 135, 136) comprises at least one first region (28a, 130a, 131a, 132a, 133a, 134a, 135a, 136a) for positioning over at least one of the combustion air passage openings (22) and a second region (28b) for fixing in the fan chamber or combustion air pre-chamber (20) of the evaporator burner (4), the first region being in the shape of a tongue. The invention also relates to a fastening element having a flow-directing insert, to a flow-directing system and to a heating device.
