<p>An atomizer(5) for atomizing a liquid has a gas chamber (15) adapted to be connected to a supply of gas and a liquid chamber (30) adapted to be connected to a source of liquid. A mixing tube (38) extends from the gas chamber (15) in a downstream direction, and atomizing gas flows through the tube (38) at subsonic speed. A liquid conduit (32) fluidly connects the liquid chamber (30) with the mixing tube (38) so that liquid from the conduit (32) can be entrained in the gas flow for discharging a mixture of gas and partially atomized liquid from the tube (38). The mixture then flows through an exit gap (65) to the exterior of the housing (10). The exit gap (65) has several successive shear steps (45) which contact the mixture as it flows through the gap (65) to thereby substantially fully atomize the liquid as it is being discharged from the atomizer (5). The atomizer (5) permits variations in the liquid flow rate and therewith variations in the rate at which atomized liquid is discharged from the atomizer (5) by modulating the rate at which the liquid is entrained in the gas streams while maintaining the gas stream flow rate and pressure substantially constant.</p> |
