Abstract

Hand burner for flame-treating surfaces, with a supply device for a fuel gas/air mixture. At the end of a mixing pipe, a burner head (1) with a nozzle member (2) is arranged, in which there is a nozzle (5) for the outlet of the fuel gas/air mixture and to which is fastened a combustion chamber (4) which extends in the direction of flow and has a casing (3). The chamber has at least one opening (11) for the entry of ambient air. To achieve the aim of obtaining a stable flame and avoiding the casing heating up, the at least one air entry opening (11) is delimited towards the outside by the casing (3) of the combustion chamber (4). The opening (11) extends over the greater part of the circumference of the casing (3) in the region of the openings (11) and more particularly in such a manner that the ambient air is guided in immediate proximity and essentially parallel to the respectively adjacent generating line of the casing (3). <IMAGE>
