Evaporation- Inorganic Chemistry for Industries
Evaporation, in a technical sense, denotes the conversion of a

or they may pass through flues or pipes, set into the vessel, so that the liquid surrounds them on all sides (Fig. 1). Such pans are often several yards in length, and may contain one large flue, or several small ones, according to the work desired; but this form of apparatus is expensive to build, and difficult to keep in repair.
There are various ways of setting the pans for this process; a simple method is shown in Fig. 2. A modification of this method is the use of a long cylinder, set at a slight incline, and revolving about its longitudinal axis (Fig. 3). The lower end is open for the entrance of the flames and gases from the grate (A), which pass through the cylinder (B), on their way to the
the salts which they contain; and for the treatment of sewage and other liquid refuse.
The third method of evaporation, by the use of steam heat, is
