Device and method for dynamically mixing a second gas in a first gas.The said device comprising an enclosure (1) for mixing substantially tubular, a first inlet for a current (4) of the first gas รด an end (2) of said enclosure, a second inlet port (6) for a stream of the second gas located downstream of said first port in the flow direction of the flow of the first gas, mixing means (10) homogeneous said first and second gas streams located downstream of said second inlet port, an outlet port (3) of the downstream mixture said mixing means (10), at the other end of said enclosure, and a sampling orifice (11) of said mixture of the first and second gas located between said mixing means (10) and said output means (3) of mixture, said device further comprising means (5, 8, 9) for send a controlled flow rate of the flow of the first gas into said enclosure and a controlled flow rate of the current of the second gas in said enclosure. |
