External Vaporizers.—External vaporizers are generally formed by a cylinder with partitions constituting two series of chambers. In one of these the hot gases

from the generator travel, and in the others the water to be vaporized is contained.

Fig. 117.—Deutz vaporizer.

Tubular Vaporizers.—Different types of tubular vaporizers are manufactured. The vaporizer with a series of tubes, as in Taylor's apparatus (Fig. 116), Deutz's old model (Fig. 117), or with single tube like Pintsch's generator (Fig. 118), is formed by three compartments separated by two tube sheets or by plates which are connected by tubes.

In some cases the gases pass within the tubes, while the water to be vaporized surrounds them; as in the

Pintsch apparatus (Fig. 118), and Taylor apparatus (Fig. 116), Benz (Fig. 119), and Koerting generators (Fig. 120).
