<p>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 of atomized fuel into the chamber (12).</p> |
