Abstract

The present invention provides a booster apparatus (10) for entraining gas in a flowing second fluid. The booster apparatus comprises a booster housing (116) for receiving a fluid. The booster apparatus has at least one inlet (123) through which a first fluid passes to be entrained in the second fluid when the second fluid is flowing through the booster housing. The present invention also provides a booster assembly (12) comprising a booster apparatus (10) and a fluid motive mechanism such as a turbine unit (11).

IPC Classes  ?

• F04F 1/18 - Pumps using positively or negatively pressurised fluid medium acting directly on the liquid to be pumped the fluid medium being mixed with, or generated from, the liquid to be pumped
• F04F 5/04 - Jet pumps, i.e. devices in which fluid flow is induced by pressure drop caused by velocity of another fluid flow the inducing fluid being liquid displacing elastic fluids
• F04F 5/00 - Jet pumps, i.e. devices in which fluid flow is induced by pressure drop caused by velocity of another fluid flow
• F15D 1/02 - Influencing the flow of fluids in pipes or conduits
• F03B 3/04 - Machines or engines of reaction typeParts or details peculiar thereto with substantially axial flow throughout rotors, e.g. propeller turbines
• F03B 17/04 - Alleged perpetua mobilia
• B01F 5/04 - Injector mixers
• B01F 3/04 - Mixing, e.g. dispersing, emulsifying, according to the phases to be mixed gases or vapours with liquids
