Abstract (en)
[origin: EP1369498A1] For high speed flame spraying, the spray particles are accelerated in a flame spray of combustion gases. The powder tube (2) and the outer jet body (1) together form a Laval jet (5) to accelerate the flame spray to a speed up to 800 m/second, where the injection of the spray particles is axial and centrally in diverging sections of the jet structure. The Laval jet has a high pressure combustion chamber (3), with feed tubes (4) for the delivery of oxygen and a combustion gas e.g. propane, propylene, hydrogen, ethene and acetylene, or a kerosene.
