Abstract
Abstract A burner apparatus for burning petroleum products during well testing. The apparatus comprises a plurality of burner nozzles for mixing air, oil or other flammable hydrocarbon, and in some cases steam, and discharges the mixture for burning. Each module may have a plurality of burner nozzles, and a plurality of such modules may be connected together. Each burner nozzle has a body with an air inlet and a fluid inlet, a nozzle insert disposed in the body and having an air port in communication with the air inlet and a fluid port in communication with the fluid inlet. Sealing is provided between the nozzle insert and the body. The body may also have a steam inlet, and the nozzle insert may also have a steam port in communication with the steam inlet, for directing steam into the apparatus to increase the mixing energy and temperature, thereby facilitating atomization. A single pilot and igniter system may be used for substantially simultaneously igniting the air and fluid mixture discharged from the nozzle inserts.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
A burner apparatus comprising: a plurality of burner nozzles, each burner nozzle having a central axis and comprising: a body defining a body cavity therein and an air inlet and a fluid inlet in communication with said body cavity; a nozzle insert disposed in said body cavity and defining a central opening therethrough and an air port in communication with said air inlet and a fluid port in communication with said fluid inlet; and means for sealingly separating said air inlet and said fluid inlet; an air manifold having a longitudinal central axis and defining an air manifold cavity therein in communication with each of said air inlets, wherein: each central axis of said burner nozzles is angularly disposed with respect to said central axis of said air manifold; and said burner nozzles are circumferentially spaced from one another about said central axis of said air manifold; and pilot lighting means for substantially simultaneously igniting an air and fluid mixture discharged from said nozzle inserts.
Claim 2
Dependent Claim
165 words
A burner apparatus comprising: a plurality of burner nozzles, each burner nozzle having a central axis and comprising: a body defining a body cavity therein and an air inlet and a fluid inlet in communication with said body cavity; a nozzle insert disposed in said body cavity and defining a central opening therethrough and an air port in communication with said air inlet and a fluid port in communication with said fluid inlet; and means for sealingly separating said air inlet and said fluid inlet; an air manifold having a longitudinal central axis and defining an air manifold cavity therein in communication with each of said air inlets, wherein: each central axis of said burner nozzles is angularly disposed with respect to said central axis of said air manifold; and said burner nozzles are circumferentially spaced from one another about said central axis of said air manifold; and pilot lighting means for substantially simultaneously igniting an air and fluid mixture discharged from said nozzle inserts.
Claim 3
Dependent Claim
32 words
The apparatus of claim 1 wherein said pilot lighting means is mounted on said air manifold such that said pilot lighting means is substantially equally spaced from each of said burner nozzles.
Claim 4
Dependent Claim
31 words
The apparatus of claim 1 wherein the central axis of each of said burner nozzles is angularly disposed with respect to the central axes of all of the other burner nozzles.
Claim 5
Dependent Claim
52 words
The apparatus of claim 1 wherein said air port is one of a plurality of air ports, at least some of said air ports having axes which are substantially in a single plane and at least one of said ports having an axis which is angularly disposed with respect to said plane.
Claim 6
Dependent Claim
19 words
The apparatus of claim 4 wherein said plane is substantially perpendicular to a central axis of said nozzle insert.
Claim 7
Dependent Claim
52 words
The apparatus of claim 1 wherein: said body further defines a steam inlet in communication with said body cavity; said nozzle insert further defines a steam port in communication with said steam inlet; and said sealing means is further adapted for sealingly separating said steam inlet from said air and fluid inlets.
Claim 8
Dependent Claim
142 words
A burner apparatus comprising: a plurality of burner nozzles, each burner nozzle comprising: a body defining a body cavity therein and an air inlet and a fluid inlet in communication with said body cavity; a nozzle insert disposed in said body cavity and defining a central opening therethrough and an air port in communication with said air inlet and a fluid port in communication with said fluid inlet; and means for sealingly separating said air inlet and said fluid inlet; an air manifold defining an air manifold cavity therein in communication with each of said air inlets, said air manifold defining a central opening therethrough; and pilot lighting means for substantially simultaneously igniting an air and fluid mixture discharged from said nozzle inserts, said pilot lighting means being mounted on said air manifold and at least partially disposed through said central opening.
Claim 9
Dependent Claim
142 words
A burner apparatus comprising: a plurality of burner nozzles, each burner nozzle comprising: a body defining a body cavity therein and an air inlet and a fluid inlet in communication with said body cavity; a nozzle insert disposed in said body cavity and defining a central opening therethrough and an air port in communication with said air inlet and a fluid port in communication with said fluid inlet; and means for sealingly separating said air inlet and said fluid inlet; an air manifold defining an air manifold cavity therein in communication with each of said air inlets, said air manifold defining a central opening therethrough; and pilot lighting means for substantially simultaneously igniting an air and fluid mixture discharged from said nozzle inserts, said pilot lighting means being mounted on said air manifold and at least partially disposed through said central opening.
