ABSTRACT:
A burner nozzle for petroleum products. The burner nozzle comprises a housing portion with a nozzle assembly disposed therein. In the nozzle assembly are an outer disc and an inner disc disposed in the outer disc. Helical ramps on the outer and inner discs define gaps or fluid flow orifices therebetween. A spring biases the ramp on the inner disc toward the ramp on the outer disc. Fluid pressure in the tube portion forces the ramps apart to increase the orifice size to maintain a relatively high fluid flow velocity through a wide flow rate range. Fluid is discharged from the orifices in a spiraling pattern and impinges a conical inner surface of a swirl chamber from which the fluid is discharged from the burner nozzle.
