Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
162 words
A method for charging fluid fuel and combustion-supporting gas streams into a generally cylindrical combustion chamber of a burner and for reducing the pressure drop of the fluids charging the burner, comprising: contacting at least one fluid fuel stream with At least one combustion-supporting gas stream for mixing said streams together with the attitude of contacting being sufficient to cause the mixture to rotate in a first direction, said first direction being one of a clockwise or counterclockwise direction about an axis directed in a generally common direction relative to the longitudinal axis of said combustion chamber; and rotating the mixture in the first direction through a conduit and injecting said mixture from the conduit tangentially into the combustion chamber, the rotating mixture entering the burner chamber at a tangential attitude for producing a clockwise rotation in the combustion chamber where the first direction is clockwise and for producing a counterclockwise rotation in the combustion chamber where the first direction is counterclockwise.
Claim 2
Independent Claim
162 words
A method for charging fluid fuel and combustion-supporting gas streams into a generally cylindrical combustion chamber of a burner and for reducing the pressure drop of the fluids charging the burner, comprising: contacting at least one fluid fuel stream with At least one combustion-supporting gas stream for mixing said streams together with the attitude of contacting being sufficient to cause the mixture to rotate in a first direction, said first direction being one of a clockwise or counterclockwise direction about an axis directed in a generally common direction relative to the longitudinal axis of said combustion chamber; and rotating the mixture in the first direction through a conduit and injecting said mixture from the conduit tangentially into the combustion chamber, the rotating mixture entering the burner chamber at a tangential attitude for producing a clockwise rotation in the combustion chamber where the first direction is clockwise and for producing a counterclockwise rotation in the combustion chamber where the first direction is counterclockwise.
Claim 3
Dependent Claim
14 words
A method, as set forth in claim 1, wherein said fluid fuel comprises oil.
Claim 4
Dependent Claim
18 words
A method, as set forth in claim 1, wherein said burner is part of a carbon black reactor.
Claim 5
Dependent Claim
67 words
A method, as set forth in claim 1, wherein contacting said at least one fluid fuel with said at least one combustion-supporting gas stream comprises spraying the fuel stream axially into a generally cylindrical mixing element chamber and passing the combustion-supporting gas stream tangentially into the mixing element chamber and into contact with the fuel stream for causing the resulting mixture to rotate in the first direction.
Claim 6
Independent Claim
267 words
An apparatus for charging fluid fuel and combustion-supporting gas streams into a cylindrical chamber of a burner and reducing the pressure drop of the fluids charging the burner, comprising: a mixing element having a generally cylindrical mixing chamber of a first diameter with a longitudinal axis and first and second ends, said mixing element having a middle portion having an opening into the middle portion of said mixing chamber,; means for passing a first fluid fuel stream into the mixing chamber at said first end thereof; means for passing a first combustion-supporting gas stream tangentially into the mixing chamber at a location spaced from said opening and adjacent the location of entry of said first fuel stream for mixing the first combustion-supporting gas and the first fuel stream and causing the resulting mixture to rotate about the longitudinal axis of said mixing chamber in a first direction, said first direction being one of a clockwise or counterclockwise direction relative to the longitudinal axis of the mixing chamber; a burner having a combustion chamber with a longitudinal axis directed in generally a common direction relative to the longitudinal axis of the mixing chamber; a conduit having one end connected to the mixing element in communication with said opening into the mixing chamber and the other end connected to the burner and opening tangentially into the combustion chamber, said conduit opening into the combustion chamber at an attitude for producing a clockwise rotation in the combustion chamber where the first direction is clockwise and for producing a counterclockwise rotation in the combustion chamber where the first direction is counterclockwise.
Claim 7
Independent Claim
267 words
An apparatus for charging fluid fuel and combustion-supporting gas streams into a cylindrical chamber of a burner and reducing the pressure drop of the fluids charging the burner, comprising: a mixing element having a generally cylindrical mixing chamber of a first diameter with a longitudinal axis and first and second ends, said mixing element having a middle portion having an opening into the middle portion of said mixing chamber,; means for passing a first fluid fuel stream into the mixing chamber at said first end thereof; means for passing a first combustion-supporting gas stream tangentially into the mixing chamber at a location spaced from said opening and adjacent the location of entry of said first fuel stream for mixing the first combustion-supporting gas and the first fuel stream and causing the resulting mixture to rotate about the longitudinal axis of said mixing chamber in a first direction, said first direction being one of a clockwise or counterclockwise direction relative to the longitudinal axis of the mixing chamber; a burner having a combustion chamber with a longitudinal axis directed in generally a common direction relative to the longitudinal axis of the mixing chamber; a conduit having one end connected to the mixing element in communication with said opening into the mixing chamber and the other end connected to the burner and opening tangentially into the combustion chamber, said conduit opening into the combustion chamber at an attitude for producing a clockwise rotation in the combustion chamber where the first direction is clockwise and for producing a counterclockwise rotation in the combustion chamber where the first direction is counterclockwise.
Claim 8
Dependent Claim
120 words
An apparatus, as set forth in claim 5, wherein the size of said opening into the middle portion of said mixing chamber, the inside diameter of said conduit, and said first diameter are substantially equal; additionally comprising means for passing a second fuel stream into the mixing chamber at said second end of the mixing chamber; and means for passing a second combustion-supporting gas stream tangentially into the mixing chamber at a location adjacent the location of entry of said second fuel stream, said second combustion-supporting gas stream being directed relative to the longitudinal axis of said mixing chamber for causing the second combustion-supporting gas stream to rotate about the longitudinal axis of the mixing chamber in the first direction.
Claim 9
Dependent Claim
25 words
An apparatus, as set forth in claim 5, wherein said first fuel stream comprises oil and the Burner is part of a carbon black reactor.
Claim 10
Dependent Claim
29 words
An apparatus, as set forth in claim 5, wherein said means for passing said first fuel stream comprises means for spraying the first fuel stream into the mixing chamber.
Claim 11
Dependent Claim
20 words
An apparatus, as set forth in claim 5, wherein said first fuel stream passes generally axially into the mixing chamber.
Claim 12
Dependent Claim
27 words
An apparatus, as set forth in claim 6, wherein said first and second fuel streams comprise oil and the burner is part of a carbon black reactor.
Claim 13
Dependent Claim
39 words
An apparatus, as set forth in claim 6, wherein said means for passing said first fuel stream and said means for passing said second fuel stream each comprise means for spraying the respective fuel stream into the mixing chamber.
Claim 14
Dependent Claim
22 words
An apparatus, as set forth in claim 6, wherein said first and second fuel streams pass generally axially into the mixing chamber.
