Claim:
A chamber comprising a fluid distributor comprising: a) a horizontally positioned outer conduit; b) a first inlet port connected to said outer conduit for introducing fluid into said outer conduit; c) a first outlet port connected to said outer conduit for discharging fluid from said outer conduit; d) an inner conduit positioned horizontally and coaxially within said outer conduit, wherein said inner conduit has an inner conduit wall, wherein said inner conduit wall and said outer conduit define at least in part an annular space, wherein said annular space is in fluid communication with said first inlet port and said first outlet port, and wherein said inner conduit wall defines at least in part an inner space within said inner conduit; e) a second inlet port connected to said inner conduit for introducing fluid into said inner conduit, wherein said second inlet port is in fluid communication with said inner space; and f) a second outlet port connected to said inner conduit and in fluid communication with said inner space for discharging fluid from said inner space, further characterized in that the area of the cross-section of said annular space, wherein the cross-section of said annular space is perpendicular to the longitudinal axis of said annular space, is greater than the area of the cross-section of said inner space, wherein the cross-section of said inner space is perpendicular to the longitudinal axis of said inner space.
