Improvements in and connected with Refuse Consuming Furnaces.
SAULO COMOLLI of Nos. 9 & 11 Moor Lane in the City of London in the
County of Middlesex do hereby declare the nature of this invention to be as
follows:-
The system consists in burning the materials between two surfaces more or less
parallel and a little distant one from the other by the combustion of gas (oxide of
carbon or other) mixed in proper proportions with the air.
The principle application of our system is for the burning of refuse a proceeding
which has often been tried but whose theoretical and practical solution has always
given unsatisfactory results.
To better explain our system we are taking the most difficult case and which is
interesting to the public hygiene.
The refuse of towns which are always a germ of infection and the principal cause
of epidemics. It is of great interest to destroy their refuse and the only effective
and speedy way is to burn it completely. For this our furnace finds its principal
application and gives a very satisfactory solution of the problem.
We employ as a means of combustion the gas oxide of carbon or other which can
be obtained by any gas generator (Siemens or other).
The refuse is brought to the top of the furnace and falls through a series of
orifices (B) in the circular gallery (A) which is a narrow one. It is in this gallery
that the mixture of oxide of carbon and air are burning. The gas and the air
arrive by the lateral partitions in which during the construction a series of cavities
in communication with the main pipes bring the gas (M) and the air (L'). The
refuse placed there in a very high temperature is consumed. The gas resulting
from the combustion passes through (F. H) to the chimney (Y). The ashes are
taken away by the openings (C). A series of small waggons complete the service
one portion takes the refuse to the top of the furnace the other takes the ashes
away.

gallery (A) we have left cavities which are in communication with the internal
chimneys (E) which take the gas produced by the combustion into (F). In this
way we avoid the agglomeration of the gas in the gallery (A). As represented by
the design we can better compare our furnace to a double furnace both covered by
a spherical dome one smaller than the other and placed oue on the other leaving
between them all round an empty space which is our gallery (A) and at the top
the space (F) which is the general conduit of the gas produced by the combustion.
The internal furnace is divided in half by the vertical wall (H¹) and the two
divisions are used to warm (by the gas of the combustion which has a high
temperature) the air which is wanted. The spherical dome has four (or more if
necessary) openings where are placed circular registers (G) combined together by
a balancing movement so as to pass the external air either on the side (H) as in our
design or on the opposite side. In this way when the produce of the combustion
has been some time on one side of the partition (H¹) and has warmed this side a
single movement of the balance is sufficient to pass the produce on the other side
of (H) at the same time that the external air passes in the first side and takes the
heat left in it.
When the air passes on the right of (H¹) the gas of the combustion passes to the
left and vice versa.
With this we have a veneration of heat. The gas and the warm air pass in the

SAULO COMOLLI of 9 & 11 Moor Lane in the City of London (a. communi-
cation from Louis Antoine Comolli & Charles Conteville Engineers, the former
Italian & the latter Brazillian both domiciled in Rio Janeiro No. 101 Rua de
St. Jose Capital Federal of the United States of Brazil, 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 system consists in burning the materials between two surfaces more or less
parallel and a little distant one from the other by the combustion of gas (oxide of
carbon or other) mixed in proper proportions with the air.
The principle application of our system is for the burning of refuse a proceeding
which has often been tried but whose theoretical and practical solution has always
given unsatisfactory results.
To better explain our system we are taking the most difficult case and which is
interesting to the public hygiene.
The refuse of towns which are always a germ of infection and the principal
cause of epidemics. It is of great interest to destroy their refuse and the only.
effective and speedy way is to burn it completely. For this our furnace finds its
principal application and gives a very satisfactory solution of the problem.
We employ as a means of combustion the gas oxide of carbon or other which can
be obtained by any gas generator (Siemen's or other).
The refuse is brought to the top of the furnace and falls through a series of
orifices (B) in the circular gallery (A) which is a narrow one. It is in this gallery
that the mixture of oxide of carbon and air are burning. The gas and the air pass
into the gallery (A) by a series of cavities left during construction from the lateral
pipes (ML') Sheet 1.
The refuse placed there in a very high temperature is consumed. The gas
resulting from the combustion passes through the outlet and heating chambers and
galleries (F. H. J.) or (F H. I) to the chimney (Y) in the direction of the
arrows (Section A. B.). The ashes are taken away by the openings (C). A series
of small waggons complete the service one portion takes the refuse to the top of the
furnace the other takes the ashes away.
As the gas produced is always in a large quantity and volume we are provided
with a simple means for the release of the same. In the partition of the gallery (A)
we have left cavities (E') which are in communication with the internal chimneys (E)
which take the gas produced by the combustion into the chamber at top (F). In
this way we avoid the agglomeration of the gas in the gallery (A). As represented
by the design we can better compare our furnace to a double furnace both covered
by a spherical dome one smaller than the other and placed one on the other
leaving between them all round an empty space which is our gallery (A) and at
the top the space (F) which is the general conduit of the gas produced by the
combustion.
The internal furnace is divided in half by the vertical wall (H') and the two
divisions are used to warm (by the gas of the combustion which has a high
temperature) the air which is wanted. The spherical dome has four (or more if
necessary) openings where are placed circular registers (G) combined together by
a balancing movement so as to pass the external air either on the side (H) as shewn
on Sheet 1 in our design or on the opposite side.
The air entering through the inlet (G) which is a circular tube with an up and
down movement. When this tube descends through the balancer movement into
the openings of the internal spherical dome the top of the tube opens automatically
through a valve movement leaving in this way a communication for the external air
to enter the heating chambers (H). These chambers (H) at the lower part are in

page_text: communication with the conducting galleries (I or J). Each of these galleries
terminates into four openings (K) at the top (L) at the bottom Fig. 2 (K) leads to
the shaft (Y) and (L) to the pipes (L'). When the heating chamber is in com-
munication with the outside air through (G) the opening (K) at the end of the
conducting gallery is shut through a combined movement with (G) and the air is
drawn through (L) by the heat of the furnace.
'
When the inlet (G) lifts up the top valve closes and the opening in the internal
spherical dome lets the gas of combustion pass in the chamber (H). The
opening (K) at the end of the gallery opens and the gas of combustion is drawn
through the shaft (Y).
In this way when the produce of the combustion has been so.ne time on one side
of the partition (H') and has warmed this side a single movement of the balance
is sufficient to pass the produce on the other side of (H) at the same time that the
external air passes in the first side and takes the heat left in it.
When the air passes on the right of (H') the gas of the combustion passes to the!
left and vice versa.
With this we have a generation of heat. The gas and the warm air pass
alternately from the chambers (H. H) in the conduits (I. J) which terminate in
the chambers of distribution (K. L) from whence the warın air passes into the
conduit (L) and the gas to the chimney (Y).
This chamber of distribution (KL) is constructed as (Fig. 2) having a horizontal
division (L) and is opened and closed by a system of articulated registers allowing
the warm air to enter from (I. J.) Sheet 1 alternately into the lower chamber (L)
and to pass to (L) and allowing the gas arising from the combustion to enter the
upper chamber (K) and pass to the chimney (Y) through the gallery (V.).
The principal conduit (L') brings then the warm air horizontally round the
furnace Sheet 1 from which conduit (L') it passes by openings at intervals into the
interior of the furnace (A) and mixes with the oxide of carbon brought there
through the pipe (M) from the gas generator (T.).
In the interior of the furnace there is a gallery (D) round which also pass the
pipes (ML) of oxide of carbon and warm air. This gallery is also to inspect the
interior of the furnace and to light the furnace and start the combustion. The
ventilation during the inspection is kept by the chimneys (R).
We all know that the refuse contains much water which in the higher temperature
is transformed in hydrogen and carburet of hydrogen which may be utilized in
producing a higher temperature.
Our drawing provides for the case of a want of ventilation with the use of
ventilators and we may use these (if a boiler is used) to force the gas of the
combustion on the grill of the boiler and in that way complete the combustion of
the gas which may have escaped the combustion in the furnace,
A simple register allows the passage of the gas either first to the grill. of the
boiler or to the chimney.
The drawings herein referred to are those filed with the Provisional
Specification.

page_text: 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 :-
The right of any furnace which in a continual process burns (entirely or
partially) mineral and vegetable matters between two surfaces not very far from
one another employing the combustion of gas (oxide of carbon) or other mixed
with the air.
