Abstract
An apparatus for flame spraying, in particular of powder material by means of an autogenous flame, comprising a nozzle carrier which has a burner nozzle and which can be connected to a preferably tubular accelerating accessory device which is provided with coolant guide means surrounding the burner nozzle, is improved in that the accelerating accessory device (40) bears slidably against a central arm (12) of the nozzle carrier (10) with an axial portion (45), a conical region (44) adjoins the axial portion (45) at a position remote from the nozzle, and a portion (42) which outwardly embraces a combustion chamber (50) adjoins the conical region (44), wherein the combustion chamber is delimited towards the burner by a movable annular body (38). In addition the burner nozzle (9) is to be disposed approximately in one plane with flame outlet openings of the accelerating accessory device (40) and is adapted to be retracted and extended.
