Merchant. "AN IMPROVED MODE OF PREVENTING THE INCRUSTATION OF STEAM
BOILERS." A communication from abroad by Friederich Franz Joseph von Rolff
and Franz Georg Otto Kramer, both of Osnabrück, Germany.
This Invention consists in the use of sprigs or branches and leaves of oak, thorn,
beech, and birch, or other trees or plants possessing similar properties, and which
grow in open or detached sprays.
The mode of operation is as follows:-After having carefully cleaned the boiler
I take some fresh cut sprigs of oak, if possible, with leaves, tie them together in
fagots so that they may easily pass through the manhole of the boiler, then cut the
fagots open in the boiler and let them lie loose spread over the area of the boiler and
to the height of the usual water level, then fill the boiler with water ready to start.
The sprigs may also be tied together loosely with wire in the shape of spiral
brooms, and this mode is in so far preferable as it facilitates the filling and empty-
ing of the boiler. During the first few days after the boiler has been started the
sprigs and leaves will give the water a brownish colour, and cause the smell of
tannin, which however will soon cease. Where very muddy and scale producing
water is used it has been found advantageous to fill the boilers completely with
loose sprigs.
The result of our improved mode of preventing incrustation is that the scale and
mud in the water will adhere to the sprigs and leaves. The insignificant amount of

page_text: scale which adheres to the inside of the boiler is easily removed through the sludge
pipe.
The sprigs and leaves must be renewed from time to time according to the nature
of the water used.
To prevent leaves from choking the water gauge it is recommended to protect 5
the pipe with wire netting.
