MULTIPLE DISTILLATION. 207 the hot water collected from the coil drains, where the latent heat of the steam has already been abstracted by the evaporator tubes, but which has still left the sensible heat that the steam had. These are led into the top pipe (A) over the heaters. The first two, (1) and (2), being steam, give out their latent heat to the feed-water as such Fig. 22. steam passes down into the tubes of the heater, and the waters of (3), together with any steam that may have escaped through the coil drain, and all three, (1), (2), and (3), after thus imparting their heat to the feed- water surrounding the tubes, are collected in the lower pipe (B), and then gravitate into the distiller tubes.
