RATIONAL CONSTRUCTION OF FURNACES
The course of the air through these chambers is indicated by the
arrows; the colder air tends to settle upon the hearth of the
chamber. It causes sudden and irregular cooling of that portion
of the setting through which it tends to flow, and at the same
time is not preheated to a high temperature and assists very little
in the cooling of the setting. On the other hand the heating of
the setting is effected by gases which traverse these chambers in
the correct manner.
Due to the influence of the author's work, a Russian engineer,
K.-K. Adametzky (Varsovie), has secured a patent for the improve-
ment of the continuous chamber kiln by introducing supple-

mentary channels which connect the lower part of each chamber
with the upper part of the adjoining chambers. In this way it is
possible to realize the flow principles governing the heating and
cooling of gases in the operation of these kilns. However, the
construction is slightly complicated, and the author has succeeded
in finding a simpler method of accomplishing this result.
