| 摘要 |
A gas turbine engine fuel burner comprises a convergent/divergent flow passage which receives a flow of swirling fuel and air upstream of the passage throat. The fuel and air mixture passes through the throat and is entrained into a further mass of swirling air which enters the passage through air swirlers in the wall of the divergent portion of the passage. The invention is intended to promote good fuel and air mixing, fine atomization and a reduction in carbon deposition on the burner.
