ABSTRACT:
High flame stability and good starting qualities are obtained in a relatively smoke free hot gas generator including a housing 10 having an interior combustion chamber 12 with a diverging interior wall 20 that is generally a surface of revolution. An axially directed opening 18 is centered in the wall 20 and an outer, oxidant inlet 48, 52 is provided and includes swirler vanes 50 for introducing into the chamber 12 at the interior wall 20 a swirling, hollow body of oxidant such that centrifugal force will create a diverging hollow body of swirling oxidant on the interior wall 20. A central fuel inlet 52, 58 is located within the opening 18 and within the oxidant inlet 48, 52 and is generally concentric therewith. The fuel inlet 52, 58 includes swirler vanes 50 for introducing a hollow cone-like body 90, 92 of atomized fuel into the chamber 12 such that the outer surface 94 of the cone-like body 90, 92 is on the inner surface 96 of the diverging body of oxidant from substantially the point of initiation of the latter to minimize mixing between the bodies.
