Gases are mixed in a mixing device having an elongate, tubular mixing chamber (16). At an inlet end of the mixing chamber (16), an annular nozzle (15) directs a drive gas under pressure longitudinally into the chamber (16). Inwardly, and optionally also annularly outwardly of the nozzle (15), a passive drive gas is induced or entrained to flow into the chamber (16) and to mix with the drive gas. Entrainment and mixing are enhanced by providing an interface between the drive gas and the passive gas over a large area, proportionally to a circumference of the nozzle (15). |
