APPARATUS FOR MIXING GAS STREAMS

摘要

An apparatus for mixing gas streams includes a duct (20) for carrying the first gas stream in a certain direction (22); at least one conduit (32) for carrying the second gas stream so that it interacts with the first gas stream, and a number of first holes (40) arranged along the conduit for allowing the second gas stream to leave the conduit and enter the first gas stream for mixing purposes. Each first hole is angled against the certain direction by an angle alpha, where 0° < alpha< 45° and 45° < alpha < 90° and where 0° corresponds to a direction of flow of the second gas stream that is directly opposite to the certain direction. Preferably each hole is angled against the certain direction by an angle of 15° or 75°, with a tolerance of 12°, 8° or 5°. The conduits may be located either a Short distance inside the duct at an upstream end in terms of first gas stream flow, or a short distance outside the duct likewise at its upstream end.
