NOTE ON THE CONSTRUCTION OF A DISTILLERY CHIMNEY.


At a recent meeting of the Industrial Society of Amiens, Mr. Schmidt,
engineer of the Steam Users' Association, read a paper in which he
described the process employed in the construction of a large chimney
of peculiar character for the Rocourt distillery, at St. Quentin.

[Illustration: FIG. 1--ELEVATION.]

This chimney, which is cylindrical in form, is 140 feet in height, and
has an internal diameter of 8½ feet from base to summit. The coal
consumed for the nine generators varies between 860 and 1,200 pounds
per hour and per 10 square feet of section.

The ground that was to support this chimney consisted of very
aquiferous, cracked beds of marl, disintegrated by infiltrations of
water from the distillery, and alternating with strata of clay. It
became necessary, therefore, to build as light a chimney as possible.
The problem was solved as follows, by Mr. Guendt, who was then
superintendent of the Rocourt establishment.
