ABSTRACT:
A carbureting device for the combustor of a gas turbine comprises an annular spin chamber which is defined by a generally annular housing having a closed forward end, an exhaust tube which is partially disposed within the spin chamber, and a flange disposed around the exhaust tube. A swirling air entrance is disposed between the annular housing and the flange and a fuel entrance is disposed along the annular housing spaced axially forward of the swirling air entrance. In one embodiment of the invention the exhaust tube is a venturi. In another embodiment a fairing is disposed outside and aft of the spin chamber and is sized and disposed about and extending at least to the end of the venturi, thereby forming a passageway between the fairing and the venturi. A second air swirling means is disposed in the passageway formed by the fairing and the venturi.
