Apparatus for mixing together two fluid streams comprises a first fluid conduit for carrying a first fluid stream between an inlet and an outlet, a venturi being provided in said first fluid conduit between said inlet and said outlet. The venturi comprises an upstream tapering portion which converges towards a reduced diameter throat and a downstream diffusing portion which diverges from the throat towards the outlet. The tapering portion, throat and diffusing portion are defined around a central axis. At least one mixing inlet having a discrete opening communicating with the throat of the venturi is provided for introducing a second fluid stream into the first fluid stream so that the two fluid streams mix as they flow through the venturi diffuser portion towards the outlet. The mixing inlet is configured to direct the second fluid stream into the venturi throat in a direction lying in a plane disposed at an angle between 90 DEG and 45 DEG to the axis, and a direction not more than about 30 DEG to a plane tangential to the venturi throat in the region of the mixing inlet. <IMAGE> |
