Abstract:
1. A method of flash evaporating a liquid, the method comprising: introducing the liquid into an inlet of a vaporization chamber; passing the liquid through an atomizer that is configured to ultrasonically vaporize the introduced liquid; and passing the vaporized liquid through a vapor nozzle that is fluidly cooperative with a vapor outlet of the vaporization chamber, where a collar with a first portion that forms an annular ring and a second portion that are removably connected to one another is placed in fluid communication with the vaporization chamber such that an outwardly extending first portion of the collar forms a non-filtered single opening with a substantially unobstructed vapor flowpath therethrough such that upon the passage of the vaporized liquid through the collar, it increases a pressure in the vaporization chamber while leaving the conductance of the vapor through the vapor nozzle substantially unchanged, the first portion further defining a first annular flange and the second portion defining a second annular flange that is placed adjacent the first portion such that at least the second portion defines a smaller cross-sectional area than the vapor outlet.
