Improvements in Smoke Consuming Furnaces.
We, COUNT THADÉE MIACZYNSKI, and RICHARD LEON PUCIATA, both of
7 Chmelna, Warsaw in the Empire of Russia, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in smoke consuming furnaces.
In the annexed drawings Figure 1 is a vertical section of a furnace constructed
according to our invention; Figure 2 is a front elevation and vertical section
(taken at right angles to that in Figure 1); Figure 3 is a horizontal section.
The chamber a serves as a fuel receptacle and is filled as full as possible by
means of a tube b the outer end of which is closed with a door.
care grate bars
arranged in a vertical plane and in such a manner that the bars are capable of
being removed one after the other. To do this it is only necessary to remove the
upper bar and then the other bars one after the other by causing them to slide
from bottom to top in guide grooves formed in the walls of the furnace.
f is a pivotted screen which allows of regulating the entrance of air into the
furnace.
ee are pipes parallel to the chamber a leading the air into the chambers or
pockets from whence it is sucked by the draught of the flame through the
slits g which ensures complete combustion of the gases coming from the
chamber a.
Figure 4 shows our construction of furnace with vertically arranged grate bars
applied to a boiler; all the inner walls are made of refractory bricks.
Figures 5 and 6 represent a boiler having an inside furnace constructed
according to our invention. This arrangement may be applied as an additional
heater not only to new boilers but also to existing boilers.
Figures 7 and 8 represent a furnace constructed according to our invention
applied to a boiler having an inside heating flue.
Figures 9 and 10 show the application of a furnace constructed according to our
invention to portable engines or locomotives; the furnace being placed in the
existing fire box.
Figures 11 and 12 show a double furnace constructed according to our invention
applied to existing boilers but which is also applicable to the boilers of portable
engines or locomotives. This arrangement is specially advantageous in cases
where there is little available space in front of the boiler as for example on
steamers.
Figure 13 shows the same furnace as that shown in Figure 1 except that the
pockets d are made of refractory bricks.
Figures 14 and 15 show the construction of a stove provided with a furnace
according to our invention.
Figure 16 shows a small stove for heating baths and the like.
Figure 17 shows a stove made of cast iron or other metal.
Figures 18 and 19 show a brick stove mounted on a pedestal.
Figures 20, 21 and 22 show a furnace constructed according to our invention
applied to a kitchener.
The working of the furnace is as follows: The fuel descending little by little
from the upper colder parts to the hotter layers reaches the place of combustion

page_text: in a sufficiently heated state, which greatly facilitates,its, chemical combination
with the oxygen of the air. The air necessary for combustion comes into the
furnace through the grate bars, and then when the com bustion has attained the
necessary intensity a supplementary draught of air is produced by the flame itself
which insures complete combustion of the gases formed. The temperature of the
gases at the time when they receive a fresh quantity of air is sufficiently elevated
(usually it is greater than in ordinary furnaces) to cause the regulation of the
additional current to be produced by the construction of the pockets d in such
manner that this current shall not lower the temperature below that at which
combustion would no longer be complete. This additional current of air is besides
sufficiently heated in traversing the pipes e.
The whole construction insures the perfect working of the furnace and such
regularity of action that this system advantageously competes with the most
complicated and costly furnaces differing from the latter by its simplicity which
makes our furnaces the least complicated of apparatus.
The principal advantages of the furnaces constructed according to our invention
are as follows:-
1. Simplicity of construction which allows of any form (even the most simple)
of grate bars to be used.
2. The stoking of the furnace is most easy and consists only in charging the fuel
and taking out the cinders at the lower part of the fire, the whole work of the
stoker being limited to stirring the fuel by means of a poker through the lower
grate bars, and when necessary lifting out these bars from time to time for taking
out the cinders.
3. The possibility of employing in the same furnace any kind of fuel such as
wood, oil peat and even dust or refuse, the small particles of fuel which fall through
the lower grate bars may be recharged into the furnace.
4. The very considerable strength of the draug ht and the possibility of reducing
the size of the grate on account of its vertical arrangements which allows of having
the spaces between the grate bars larger than in ordinary grates.
5. The complete combustion of the furnace gases insured by this arrangement
and especially by the supplementary draught of heated air through the pockets
formed in the inside.
6. Considerable economy of fuel as compared with other systems and especially
with ordinary furnaces.

Improvements in Smoke Consuming Furnaces.
We, COUNT THADÉE MIACZYNSKI, and RICHARD LÉON PUCIATA, both of
7 Chmelna, Warsaw, in the Empire of Russia, 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 relates to improvements in smoke consuming furnaces.
In the drawings left with the Provisional Specification Figure is a vertical
section of a furnace constructed according to our invention; Figure 2 is a front
elevation and vertical section (taken at right angles to that in Figure 1); Figure 3
is a horizontal section.
The chamber a serves as a fuel receptacle and is filled as full as possible by
means of a tube b the outer end of which is closed with a door.

6. Considerable economy of fuel as compared with other systems and especially

Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combustion chamber a filled to the top with fuel by the upper opening
furnished with doors.
2. The vertical arrangement of grate the admission of air through the bars
of the grate into the chamber a being capable of regulation by the movable
,screen f.
3. The lateral passages e formed in the walls of the furnace and leading into the
chambers or pockets d supplementary air heated by its passage through the
conduits e this air being discharged through slits 9 (acting as tuyeres) at
the point of the combustion of the gases whereby complete combustion is
:assured.
4. The combination of arrangements forming a special system of smoke consuming
furnace, substantially as described and shown in the drawings.
