hottest portion of the chamber where complete combustion can
take place before the gases cool below their ignition temperature.

The hot gases drop down toward the ingots or billets and lose
their heat by coming in contact with them, and the colder gases
then descend fur-

Compare this
type of construc-

designs. Fig. 116
is a photographic
demonstration of
the circulation of
the hot gases (colored kerosene) in a Morgan continuous heat-
