Abstract
Abstract In a method of mixing two or more gas flows, the gas flows are passed through an array of at least three parallel adjacent guide conduits so as to emerge from said conduits into a mixing zone as a corresponding array of parallel adjacent streams flowing in the same direction. The gas flows are distributed alternatingly in said conduits so that each said stream has, as each of its neighbours, a gas stream from a different said gas flow. To improve mixing and shorten the required length of the mixing zone, the streams derived from the respective gas flows have different velocities at their emergence from the guide conduits into the mixing zone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A method of mixing two or more gas flows in which the gas flows are passed through an array of at least three parallel adjacent guide conduits so as to emerge from said conduits into a mixing zone as a corresponding array of parallel adjacent streams flowing in the same direction, the gas flows being distributed alternatingly in said conduits so that each said stream has, as each of its neighbours, a gas stream from a different said gas flow, characterised in that the streams derived from the respective gas flows have different velocities at their emergence from the guide conduits into the mixing zone.
Claim 2
Independent Claim
105 words
A method of mixing two or more gas flows in which the gas flows are passed through an array of at least three parallel adjacent guide conduits so as to emerge from said conduits into a mixing zone as a corresponding array of parallel adjacent streams flowing in the same direction, the gas flows being distributed alternatingly in said conduits so that each said stream has, as each of its neighbours, a gas stream from a different said gas flow, characterised in that the streams derived from the respective gas flows have different velocities at their emergence from the guide conduits into the mixing zone.
Claim 3
Independent Claim
30 words
A method according to claim l wherein the velocity difference between the streams of two said gas flows respectively at emergence from the guide conduits is at least 2 m/s.
Claim 4
Dependent Claim
15 words
A method according to claim 2 wherein said velocity difference is at least 5 m/s.
Claim 5
Dependent Claim
15 words
A method according to claim 3 wherein said velocity difference is at least l0 m/s.
Claim 6
Independent Claim
47 words
A method according to any one of the preceding claims wherein each guide conduit containing a first one of said gas flows has a flow cross section area which is greater than the flow cross section area of each guide conduit containing a second said gas flow.
Claim 7
Independent Claim
35 words
A method according to any one of the preceding claims wherein at their mouths opening into the mixing zone said conduits each have a slot shape in cross section perpendicular to the gas flow direction.
Claim 8
Dependent Claim
20 words
A method according to claim 6 wherein the slots are rectangular and have their elongate axes parallel to each other.
Claim 9
Dependent Claim
23 words
A method according to claim 6 or claim 7 wherein the width of each slot is in the range 7 to 40 cm.
Claim 10
Dependent Claim
20 words
A method according to claim 8 wherein the width of each slot is in the range l0 to 25 cm.
Claim 11
Dependent Claim
30 words
l0. A method according to any one of the preceding claims wherein there are two said gas flows and the total number of said guide conduits is at least five.
