Abstract
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.

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.
Claim 2
Dependent Claim
119 words
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.
Claim 3
Dependent Claim
69 words
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.
Claim 4
Dependent Claim
69 words
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.
Claim 5
Dependent Claim
78 words
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.
Claim 6
Dependent Claim
78 words
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.
Claim 7
Dependent Claim
