An Improved Method of and Apparatus for Removing Particles of
Soot and Ash from the Waste Gases Emitted by Chimneys.
I, MAXIMILIAN ALBERT GUTZNER of 13 Hubertusstrasse, Steglitz / Berlin,
Germany, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention has for its object the separation of particles of soot and ash from;
the waste gases emitted by chimneys.
The invention consists in providing a water sprinkling apparatus which both
produces a draught and also washes the gases before they pass off into the-
atmosphere. The waste gases are in this manner freed from substances dangerous
to the health.
In carrying out my invention the gases are led into a chamber the bottom or floor-
of which is covered with water. In the chamber water sprinkling nozzles or roses
are so arranged that not only are the gases thoroughly washed but a sufficient
draught, to draw the gases into the chamber, is created. The chamber is, of course,
provided with an efflux arrangement for running off the dirty water and also with
an outlet through which the purified gases can escape.
The method of carrying out my invention is shown, on the accompanying drawing,.
by way of example, as applied to a dwelling house.
Referring to the drawing.

A are the stoves from which the waste gases pass by branches or outlets 6 into,
the vertical, so called, "Russian" tubes a. On the drawings two tubes a are shown
one for each set of stoves. The tubes a are, at top, closed tightly by lids c which
can be removed at any time for the purpose of cleaning the tubes. The tubes a, at
their lower ends, communicate with canals d which lead into the washing chamber B.
The washing chamber has an efflux e for dirty water and an exit f for the purified
gases. A sufficient number of water sprinkling or spraying roses or nozzles g, h,.
to create a draught to draw the gases from the stoves and to thoroughly purify
them, are arranged in the chamber B.
The first sprinkler g, or series of sprinklers if more than one is employed, serves.
principally to create a strong draught and to wet the particles of soot and ash and
cause them to fall to the floor of the chamber. The second nozzle (or series of
nozzles) h, which delivers a fine spray D, is for the purpose of throwing back into
the chamber any particles of soot &c. which may not have been sufficiently wetted
by the water from the nozzles g and which would otherwise have escaped into the
chimney. The direction and strength of the second spraying arrangement / must
be so arranged as not to materially interfere with the draught produced by the
action of the roses g. The sooty water passes off from the chamber by the pipe e.
The arrangement and size of chamber B, the inflow and outlet canals d, e, f, and
the water jet and water-spray appliances g and h, must be altered to suit different
circumstances and requirements and regard must be paid to the amount of the gases
to be washed and the heat of the same. Such alterations however do not affect
the principle of the invention which consists, generally in freeing the gases from
soot and ash, by washing, before their escape, into the atmosphere.
By this invention the air in large manufacturing towns can be purified and freed
from substances hurtful to the growth of plants and trees and to the health of
human beings. Also the draught in the chimneys is always regular and is entirely
independent of the state of the weather. Further, downdraughts are prevented,.
and, as a consequence, there is no possibility of carbonic-acid gas poisoning,.

defective stoves are used.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A method of separating soot and ash from chimney gases, consisting in first
sucking the gases into a chamber by means of a draught producing water jet (or
jets) and then washing them in the chamber by means of the said jet (or jets) and
also by a second water spraying jet (or series of jets), the dirty water with the soot
and ash being run off by an exit and the purified gases escaping by a suitable outlet,
substantially as hereinbefore set forth.
2. The apparatus for carrying out the above mentioned method, substantially as
hereinbefore described with reference to the drawing annexed.
Dated this 21st day of May 1892.
