I, ALPHONSE REIS, Engineer in care of Messrs. E. Bede & Co, 41, rue du Marteau,
Brussels, do hereby declare the nature of said invention for "AN APPARATUS
FOR PRODUCING A DRAUGHT IN BOILER AND OTHER FURNACES AND FOR PURIFYING
THE PRODUCTS OF COMBUSTION, to be as follows:-
My invention relates to apparatus for producing an artificial draught and for
purifying at the same time the gaseous products of combustion.
The apparatus comprises a suction pump (or exhauster) a straining appliance
composed of a series of metallic sieves or sheets of wire gauze, placed close together,
and a purifying tank, containing a solution of appropriate chemicals.
The pump (or exhauster) has for its object to draw the furnace gases across the
strainer, which retains a portion of the heat of the said gases and separates from
the same the soot and other solid admixtures, and through the purifying liquid,
which retains the gaseous impurities and especially those, which would be detri-
imental to health.
The furnace fumes first enter a soot chamber, where the soot is deposited on a
movable slide forming the bottom of the chamber, after which the gases pass
through the strainer into a tube leading into the liquid contained in the purifying
tank. The latter is a closed vessel, filled to about two thirds or three fourths
with a solution of caustic soda, caustic lime, or pure water, which is constantly
renewed and serves to deprive the furnace gases of their carbonic oxide, carbonic
acid and sulphurous or sulphuric acid.
From the upper part of the tank, the purified gases are drawn by the pump,
which discharges them into the atmosphere.
Where it is not required to purify the products of combustion from noxious
gases, the purifying tank may be filled with water, instead of solutions of
chemicals,

I, ALPHONSE REIS, of Antwerp in the Kingdom of Belgium, 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:―
My invention relates to apparatus for producing an artificial draught and for
purifying at the same time the gaseous products of combustion.
The apparatus comprises a suction pump (or exhauster) a straining appliance
composed of metallic sieves or sheets of wire gauze placed close together, and a
purifying tank containing a solution of appropriate chemicals.
The pump (or exhauster) has for its object to draw the furnace gases. through
the strainer, which retains a portion of the heat of the said gases and separates
from the same, the soot and other solid admixtures; and through the purifying
liquid which retains the gaseous impurities and especially those which would be
detrimental to health.
:
Referring to the accompanying drawing The fumes from the furnace C. first
enter a Boot chamber G. where the soot is deposited on a movable slide H forming
the bottom of the chamber, after which the gases pass through the strainer F into
a tube B. leading into the liquid in the purifying tank A.
The latter is a closed
*vessel filled to about two-thirds or three-fourths with a solution of caustic soda,
caustic line, or pure water which is constantly renewed, and serves to deprive
the furnace gases of their carbonic oxydes, carbonic acid, and sulphurous and
sulphuric acids.
From the upper part of the tank A the purified gases are drawn through the
tube E by the pump D which-discharges them into the atmosphere.
Where it is not required to purify the products of combustion from noxious
gases, the purifying tank may be filled with water instead of solutions of
chemicals.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is,
The apparatus for producing a draught in boiler and other furnaces, and for
purifying the products of combustion, consisting in the combination of the
suction pump D, the filter or strainer F consisting of layers of metallic gauze, and
the purifying tank A containing a solution of the necessary chemicals.
The pump D causing the furnaces gases to pass through the strainer F which
retains the soot and also deprives the gases of their heat, and also through the
liquid purifier which retains the noxious gases.
