Abstract
A safety burner for spraying metal powder in the molten state is provided comprising a burner body and a powder supply device formed of a carrier part firmly connected to the burner body and having an intermediate part removably attached to the carrier part, the intermediate part having means for detachably coupling a powder container thereto and also having a powder shutoff device cooperably associated therewith, the intermediate part and the carrier part being arranged one to the other such that the intermediate part can be removed from the carrier part only when the powder shutoff device is closed. The burner also includes gas flow conduits within it for conveying combustible gas and an oxidizing gas and powder-carrier gas therethrough. The burner body contains a first combustible gas-oxidizing gas injector and a second powder-carrier gas injector, the first injector being coupled to the combustible gas-oxidizing gas conduit and the second injector being coupled to the powder-carrier gas conduit. A gas-shutoff device is provided coupled to the gas-flow conduits.
