ABSTRACT:
A flame spray directing means for connection to a flame spray nozzle of an autogenous flame-spraying apparatus for optimizing the working parameters of the apparatus including flame speed and kinetic energy is provided. The means comprises a hollow longitudinally extending module of tubular configuration through which flame spray material is caused to flow. The extending module has a predetermined length with one end portion thereof shaped for coupling to the flame spray nozzle and for providing a combustion chamber therefor, with its opposite end portion providing an exit end therefor. A portion of the hollow module extending from the combustion chamber to the exit end coaxially defines an extending accelerating chamber which is divided into a first stage chamber of specified diameter following the combustion chamber and a second stage chamber in which the diameter thereof less than that of the combustion chamber.
