Fuel nozzle for burner construction
Patent
·
OSTI ID:5738293
By enhancing fuel-air mixing, this two-stage burner configuration lowers the amount of noxious substances and smoke emitted. Primary fuel burns in an annulus in the first combustion zone while secondary fuel is discharged downstream to a second combustion zone. Vortex generators located in the fuel-air passageway to primary zone improve both the mixing and the toroidal flow. More vortex generators efficiently mix the secondary fuel and air and enhance combustion in the second zone as well. Additionally, a disc on the secondary nozzle tube serves as a trip device to divert the flow of fuel and air from the first zone into a recirculating path, helping concentrate the primary combustion near the inlet end of the chamber.
