Connection with Steam Boiler and other Furnaces.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
The object of my invention is to provide a means whereby the smoke from a furnace
may be condensed and carried away by means of water instead of being discharged
into the air, and thus not only free the atmosphere from impurities, and obviate the
danger of setting property on fire by sparks from smoke-stacks, but also avoid the
expense of building smoke-stacks, all as hereinafter particularly described.
In the accompanying drawings
Figure 1 is a front elevation of a battery of steam boilers and accompanying furnaces
provided with apparatus constructed according to my said invention.
Figure 2 is a central vertical section drawn to an enlarged scale through the said
apparatus and extending to and including one of the boilers on the dotted line 2, 2 in
Figure 3.
Figure 3 is a horizontal sectional view looking upwardly from the dotted line 3, 3 in
Figure 2.
Similar letters of reference indicate corresponding parts in the several Figures.
A, A represent ordinary boilers and their furnaces; B a flue or chamber into which
the products of combustion from the furnaces are immediately discharged; C a fan for

page_text: furnishing a draught to said furnaces; D the main structure of my condenser, and
E a supply-pipe by which water is conducted thereto.
The furnaces and boilers A are or may be of any ordinary or desired form, and need
no special description.
The flue B is likewise similar in form to flues which are in common use, and extends
over the several boilers to, and communicates with, the condenser. It is provided with
a damper B which is mounted on a pivot shaft b. To the side of said damper next
the fan and to the top of the flue casing are secured hinged plates which serve to
some extent as a continuation of the back wall of said fan when in use. A handle B³
is connected to the damper, by which it may be moved up and down, and the opening
thereby regulated.
The fan is any ordinary suction fan and may be driven in any desired manner,
although I prefer to drive it by a small independent engine connected by a steam pipe
to the boilers (not shown).
The casing of the condenser is preferably a cylindrical sheet metal structure, as
shown, although it may be formed of masonry, or in any of many other ways.
Near the upper end of the casing D a circular pipe I is placed, connected with the
water supply-pipe, and provided with numerous orifices as shown. These orifices I
prefer to make at an angle of about sixty degrees so that the streams of water therefrom
shall arch over and fall down toward the centre. To a central pipe D is connected a
revolving globe D³, also having numerous orifices through which small streams or
sprays of water will pass. Secured to this globe and extending up into the pipe D2 is
a screw ds by which the rotary motion is imparted thereto by the water coming through
said pipe, and thus the streams of water from the orifices in the globe are thrown out
by centrifugal force and serve to dampen everything which enters the condenser.
These several streams of water also serve to some extent to form a vacuum in the
condenser and thus the smoke from the flue will enter it freely, where, by commingling
with the water, the gases are purified, and the solids are wetted and washed down to
the bottom of the condenser, whence they run off with the water and are discharged
into a sewer or other suitable place.
In one side of the casing I prefer to place a door or window D₁ in which a glass
pane (shown as protected by an outer shield of sheet metal) is placed, so that both
access may be had to the device, and the interior observed when it is closed and in
operation.
The supply pipe E is simply an ordinary pipe by which the necessary supply of
water is conducted into the condenser; and may or may not be the same pipe by
which water is supplied to the boilers.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my foreign
Correspondent, I declare that what I claim is :-
First. The combination with a furnace, of a condenser, a conduit or flue leading
from said furnace to said condenser, a suction fan located in said conduit between said
furnace and said condenser, and a perforated circular water pipe arranged within said
condenser.
Second. The combination, in a smoke-condenser, with the water supply-pipe leading
thereto, of a central bulb or globe provided with numerous orifices and connected to
said pipe.
Third. The combination, in a smoke-condenser, of a pipe running around inside the
walls of said condenser, and provided with fine orifices for the discharge of the water,
and a revolving part also having fine orifices, whereby the air in the condenser is
thoroughly wet when the device is in operation, substantially as set forth.
Fourth. The combination, in a smoke-condenser, of a water supply pipe, a bulb or
globe provided with numerous orifices and connected to said pipe, and a screw attached
to said globe and extending up into the portion of pipe which enters it, whereby said
bulb or globe will receive a rotary motion by the force of the water entering it.

page_text: Fifth. The combination of a furnace, a conduit or flue leading directly from said
furnace, a fan located within said flue and a smoke-condenser into which said flue
discharges directly, said smoke-condenser being provided with a water supply which
discharges into said condenser in the form of spray.
Sixth. The combination of a furnace, a smoke condenser, a conduit or flue leading
directly from said furnace to said condenser, a rotary fan located within said flue
between said furnace and said condenser, and a water supply for said condenser, said
water supply being arranged to discharge into said condenser in its upper portion in
the form of spray or a multitude of fine streams, substantially as shown and described.
Seventh. The combination of a furnace, a smoke-condenser, a flue or conduit leading
from said furnace to said condenser, and a water supply for said condenser consisting
in part of a central globe or bulb having numerous orifices, substantially as set forth.
Eighth. The combination, in a smoke-condenser, of the furnace, the condenser, the
flue or conduit leading from said furnace to said condenser, a fan in said flue and a
damper having an attachment which serves as a continuation of the rear wail of said
fan, substantially as set forth.
Ninth. The combination of a furnace, a smoke-condenser, a flue or conduit leading
from said furnace to said condenser, a fan located within said flue and a damper
arranged immediately behind said fan, and adapted to be operated to adjust the
opening, substantially as, and for the purposes, specified.
