Abstract (en)
An air-fuel mixing device mixes fuel and primary combustion air in a particular configuration. Thus fuel nozzle 48 sprays the liquid fuel into the primary combustion chamber or zone 36 of a combustor 30 in a hollow conical pattern. A portion of the primary combustion air is injected toward the stream of liquid fuel in a converging annular frustrum pattern and which creates an extremely uniform fuel/air mixture and a stable flame. In a preferred embodiment, the converging annular frustrum through which primary air is injected is formed between the outer surface of the fuel nozzle means 48 and an inner flange or lip 66 of a baffle plate 60 that surrounds the fuel nozzle means 48 and is at an angle of 30 DEG with respect to the main axis of the fuel nozzle means 48.
