摘要

Process for applying surface coatings in the path of high speed flame spraying comprises atomizing kerosene in a burner containing the kerosene, oxygen and hydrogen using a combustion gas such as hydrogen, ethylene or methane; and then igniting. An Independent claim is also included for a device for carrying out the process comprising a high speed flame burner (1) with an atomizing chamber connected to a combustion chamber (2). Preferred Features: The kerosene is atomized in a vortex chamber using a combustion gas and then fed to the combustion chamber. The material to be injected is introduced in powder form into a region of a pulsation-deficient process gas stream in the combustion chamber.
