<p>Apparatus for powder spraying operated with a flame jet having a spray head for feeding the powder delivered by a carrying substance, e.g. air, into the flame jet and in the spray head body rows of bores are to be found for emitting and guiding the mixture of combustible gas to the combustion space of the flame. The essence of the apparatus according to the invention lies in that unilaterally or multilaterally arranged sideplates (10) and/or endplates (11) extending over the sprayer head body (3) on the side facing the flame space (8), formed similarly as teeth of a comb and confining the flame space (8), are fixed - preferably welded - in a heat conductive manner to the side lying perpendicularly to the surface of the sprayer head body (3), which incorporated the row (7) of bores emitting the combustible gas needed for flame maintenance.</p> |
