ABSTRACT:
The apparatus of the present invention uses a vessel with a sump for containing a liquid (103). The vessel has one or more downward angled openings (101). A heating device (104) boils the liquid to produce a vapor and a condensing apparatus (102), in the opening or in a separate chamber, prevents any vapor from exiting the apparatus. The apparatus contains a condensable liquid having a vapor density less than that of the ambient atmosphere by producing a stably stratified interface between the condensable vapor and the ambient atmosphere. The apparatus can be used for such manufacturing processes as cleaning or coating with vapors that are less dense than air.
