Abstract: A method of operating a flame spraying burner, having water-cooled combustion chamber and expansion nozzle arranged downstream of the combustion chamber, with a gaseous fuel and/or a liquid fuel in association with an oxidation gas, a compression air and/or oxygen, and feeding a spraying material alternatively axially through the combustion chamber into the flame jet or radially, transverse to the burner axis, through at least two opposite radial bores which introduce the spraying material into the expansion nozzle; and a flame spraying burner operated by such a method.

Abstract: An injector tip for burning aggregates for the mixing of fuel constituents, particularly fuel gases, auxiliary combustion gases and possibly liquid fuels is suggested which comprises feed ducts for the individual fuel constituents. The feed ducts of the individual fuel constituents are each preferably formed by a group of axial bores arranged on a circle, in which case the groups of axial bores assigned to the individual fuel constituents are arranged on concentric circles. According to the invention, the first feed ducts assigned to a first fuel constituent lead into first injector nozzle bores having a reduced cross section which in turn lead into a first radial injector gap. For the mixing of the first fuel constituent with at least a second fuel constituent, the second feed ducts assigned to the second fuel constituent must also lead into the first radial injector gap.

Abstract: The invention relates to a burner head for burner units, comprising a single or multiple injector gas mixing system for the interior and/or exterior mixing of various fuel constituents, particularly fuel gases, auxiliary combustion gases and possibly liquid fuel gases, formed by an intermediate piece in which feed ducts for the fuel constituents are provided from an equipment connecting surface to a nozzle connecting side, and comprising a nozzle which consists of a center part having ducts and at least one cap part, for the mixing of at least two fuel constituents, the first ducts assigned to a first fuel constituent and distributed around the circumference leading into first injector nozzle bores which, in turn, are connected with a radial injector gap formed by an annular gap between the center part and the cap part, and the second ducts assigned to the second fuel constituent and distributed around the circumference also leading into the radial injector gap, in which case, in the intermediate piece, radia
