Abstract

A burner nozzle for burning petroleum products. The burner nozzle includes a tube portion with a burner nozzle insert disposed therein. A nut is threadingly engaged with the tube portion to hold the insert in place. The insert has a substantially conical nozzle portion with an inlet portion extending substantially perpendicular to a longitudinal axis of the nozzle portion. The inlet portion defines a plurality of inlet ports therethrough. The inlet ports are angled with respect to the longitudinal axis and have an outlet end adjacent to an inner surface of the nozzle portion.

Claims

1. A petroleum burner nozzle comprising:

a tube portion defining a central opening therein and connectable to a fluid source;

a nozzle insert disposed in said central opening of said tube portion and comprising;

a substantially conical nozzle portion; and

a wall portion integrally formed with said nozzle portion and extending substantially perpendicular to a central axis of said tube portion, said wall portion defining a plurality of fluid inlet ports therethrough in communication with said nozzle portion;

fastening means for holding said insert in place, said fastening means being disposed radially outwardly of said insert and being characterized by a nut having a substantially conical inner surface; and

sealing means for sealing between said insert and said tube portion.

2. A burner nozzle insert comprising:

a nozzle portion having a longitudinal axis and a substantially conical inner surface cone and substantially constant radial wall thickness; and

an inlet portion adjacent to an end of said conical inner surface of said nozzle portion and intergrally formed therewith, said inlet portion defining a plurality of ports

therethrough, said ports being disposed at an acute angle with respect to said longitudinal axis.

3. A burner nozzle insert comprising:

a nozzle portion having a substantially conical configuration with substantial constant radial wall thickness and further having an outlet end, said nozzle portion defining a longitudinal axis; and

an inlet portion adjacent to said nozzle portion and opposite said outlet end wherein said inlet portion comprises a wall substantially perpendicular to said longitudinal axis adjacent to a substantially conical inner surface of said nozzle portion and defining a plurality of inlet ports therethrough.

4. The insert of claim 3 wherein said ports are angled with respect to said longitudinal axis.

5. The insert of claim 4 wherein said ports have an outlet end adjacent to a substantially conical inner surface of said nozzle portion.
