Abstract
In a two stage burner construction in which primary fuel burns in an annulus in a primary combustion zone and secondary fuel is discharged through the primary zone to a secondary zone downstream of the primary zone, vortex generators are used in the passage through which the fuel and air entering the primary zone to enhance the mixing and to improve the toroidal flow in the combustion zone. Other vortex generators are used to improve the mixing of the secondary fuel and air to improve secondary combustion. The vortex generators may be used in conjunction with a trip on the secondary nozzle tube to further enhance primary combustion.
