A flow-directing element for a heating apparatus, in particular a heating apparatus with an evaporator burner, having a body which comprises a laterally arranged inflow region on an underside of the flow-directing element, having a centrally arranged outflow region, which includes a through-passage from an underside of the flow-directing element to an upper side of the flow-directing element, the upper side being located opposite the underside, and having at least one guide element, which is arranged such that it allows flow to be guided from the inflow region to the outflow region.

Some embodiments of the disclosure provide a steam generator and a car washer with the steam generator. The steam generator includes: a boiler having a combustion chamber. The steam generator further includes: a windproof cover, at least a part of an ignition device of the steam generator being located in the windproof cover; an igniting cover, at least a part of the igniting cover being located in the combustion chamber, and an outlet of the windproof cover being located in the igniting cover; an air inlet grating, the air inlet grating being provided around the windproof cover and connected with the windproof cover, and the air inlet grating being located on an inner side of an air inlet of the igniting cover, to prevent airflow in the igniting cover from flowing out from the inlet of the igniting cover.

The present disclosure discloses a combustion chamber and a combustion apparatus. The combustion chamber includes: a first surrounding plate located on an outer side and a second surrounding plate located on an inner side. A combustion cavity is defined by the second surrounding plate. The first surrounding plate and the second surrounding plate are spaced apart from each other to define at least one air duct in communication with the combustion cavity. Each of the at least one air duct has an air inlet hole formed in the first surrounding plate, and an air outlet hole formed in the second surrounding plate.
