Abstract
An autogenous flame spraying apparatus includes a supply line housing having gas supply lines for combustion gas, carrier gas and acceleration gas; a main housing connected to the supply line housing and having a supply line for a spray powder, and ducts communicating with the gas supply lines, the housing having a first injector for mixing the spray powder and the carrier gas to form a first mixture; an interchangeable nozzle carrier for carrying a releasable torch nozzle, the carrier being releasably attached to the main housing and having a second injector for mixing the combustion gas and the carrier gas to form a second mixture, the nozzle carrier also having ducts for conveying the first mixture and the second mixture to the torch nozzle, whereby the carrier can be replaced so as to alter both flame power and feed of spray powder.
