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.

A gas turbine carbureting device for disposal in a downstream flowing compressor discharge air flow comprising: a spin chamber defined by a generally annular housing including a closed forward end having a continuous unobstructed inner surface and an open aft end wherein said forward end is upstream of said aft end with respect to the compressor discharge airflow; at least one exhaust tube having an inlet disposed within said spin chamber wherein said exhaust tube is radially spaced apart from said annular housing and which together with said annular housing forms at least in part a first annular air passage leading to said forward end; said housing having a fuel entrance and a swirling air entrance to said first annular air passage and spaced axially apart from each other, and wherein said swirling air entrance and fuel entrance are downstream of said closed forward end with respect to the compressor discharge flow; and wherein said first air passage is formed for flowing swirling air from said swirling air passage to said aft end in an upstream direction with respect to the compressor discharge flow and said exhaust tube inlet is disposed within said swirl chamber so as to reverse the axial direction of the swirling air off said forward end from an upstream direction to a downstream direction through said exhaust tube.
