Claim 1
Independent Claim
308 words
An apparatus comprising (1) a mixing zone in open communication with a source of an oxygen-containing gas and a source of a combustible gas, (2) a combustion chamber having a substantially symmetrical internal configuration and having at least one electrically generated spark-producing means in the sidewall thereof, (3) a tubular injection jet extending from said mixing chamber into said combustion chamber to a point just above said spark-producing means, said injection jet being in open communication at one end thereof with said mixing zone and at the other end thereof with said combustion chamber, the upper end of said injection jet having a diameter less than that of said lower end, at least one minor opening through the sidewall of said injection jet into said combustion chamber, said opening being adjacent the lower end of said jet and having a diameter substantially less than the diameter of said tubular injection jet, and the plane of said opening being in angular relation to the axis of said injection jet, (4) a first conducting tube in open communication at one end thereof with said combustion chamber and opening at its other end adjacent the upper end of a flare stack combustion tip, said combustion chamber and said first conducting tube being in relation such that said combustion chamber bears a volume ratio per unit length of said first conducting tube within the range of 1.7:1 to 2.25:1, (5) a second conducting tube coaxially aligned with and of greater diameter than said first conduction tube, said second conduction tube being in open communication adjacent its lower end with the source of a combustible gas and being open At its upper end to the atmosphere, said upper end terminating adjacent but below the upper end of said first conducting tube, and (6) means for causing said spark-producing means to create a spark.
Claim 2
Independent Claim
308 words
An apparatus comprising (1) a mixing zone in open communication with a source of an oxygen-containing gas and a source of a combustible gas, (2) a combustion chamber having a substantially symmetrical internal configuration and having at least one electrically generated spark-producing means in the sidewall thereof, (3) a tubular injection jet extending from said mixing chamber into said combustion chamber to a point just above said spark-producing means, said injection jet being in open communication at one end thereof with said mixing zone and at the other end thereof with said combustion chamber, the upper end of said injection jet having a diameter less than that of said lower end, at least one minor opening through the sidewall of said injection jet into said combustion chamber, said opening being adjacent the lower end of said jet and having a diameter substantially less than the diameter of said tubular injection jet, and the plane of said opening being in angular relation to the axis of said injection jet, (4) a first conducting tube in open communication at one end thereof with said combustion chamber and opening at its other end adjacent the upper end of a flare stack combustion tip, said combustion chamber and said first conducting tube being in relation such that said combustion chamber bears a volume ratio per unit length of said first conducting tube within the range of 1.7:1 to 2.25:1, (5) a second conducting tube coaxially aligned with and of greater diameter than said first conduction tube, said second conduction tube being in open communication adjacent its lower end with the source of a combustible gas and being open At its upper end to the atmosphere, said upper end terminating adjacent but below the upper end of said first conducting tube, and (6) means for causing said spark-producing means to create a spark.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein said injection jet includes a flared section between the ends thereof and adjacent the lower end of said combustion chamber.
Claim 4
Dependent Claim
58 words
The apparatus of claim 1 wherein two minor openings are provided through said flared section of said injection jet, said two minor openings being on opposite sides of said flared section and being positioned such as to lie in a vertical plane perpendicular to a line from said spark-producing means to the vertical axis of said combustion chamber.
Claim 5
Dependent Claim
15 words
The apparatus of claim 1 wherein said combustion chamber has a substantially symmetrical internal configuration.
Claim 6
Dependent Claim
38 words
The apparatus of claim 4 wherein the internal walls of said combustion chamber form a circle in any given horizontal plane and provide for the upper surfaces thereof to converge toward the upper end of said combustion chamber.
Claim 7
Dependent Claim
27 words
The apparatus of claim 1 wherein the outer surface of said combustion chamber is provided with a plurality of baffles perpendicularly arranged with respect to such surface.
Claim 8
Dependent Claim
30 words
The apparatus of claim 1 wherein said first conduction tube is provided with a circular baffle adjacent its upper end and above the upper end of said second conducting tube.
Claim 9
Dependent Claim
28 words
The apparatus of claim 1 wherein said conducting tube is provided with spiral openings adjacent its upper end and above the upper end of said second conducting tube.
