Improvements in or relating to Smoke Consuming Furnaces.
HEINRICH WERNER, of 60 Via Savona, Milan, in the Kingdom of Italy, Works
Manager, 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 smoke consuming furnaces which are particularly
suitable for porcelain ovens and the like.
The principal features of the improved smoke-consuming furnaces are the
arrangement of gratings, the way in which the combustion-gases escape and the
roof of the fire box sloping upwards in the same direction as the grating further
the arrangement for removing clinkers and slag and windows arranged in the side
of the combustion chamber for viewing the interior of the furnace. The shaft of
the fuel hopper sloping up in the same plane as the front grating is also a special
feature of the smoke-consuming furnace according to the present invention.
The furnace illustrated in the accompanying drawing in sectional side elevation
consists of an inclined front grating 1 and a second grate 2 considerably shorter
or narrower arrangel lower down and sloping slightly downwards towards the
front.
The free ends of the two grates 1 and 2 are at different levels so that there is
formed an opening between them normally closed by a valve or bars 3.
When said valve is opened by means of any suitable device such for instance
as a chain the slag formed at the bottom of the grate and which would prevent
efficient combustion can be easily removed through the opening thus uncovered.
The slag and the ashes fall into the ash pit 4 which can be emptied from below.
The roof 6 of the combustion chamber is formed so as to rise, together with the
front grate 1 towards the shaft of the fuel hopper and to converge slightly with
the front grate so that the combustion chamber 7 has its maximum height between
the rear grate 2 and the roof G.
At the upper part of this height there is arranged the flue 8 for the escape of
combustion gases which enter sail flue free of smoke.
The shaft of the filling hopper extends upwards at the same angle as the front
grate 1 and the same plane.
Owing to this arrangement the fuel enters the combustion chamber 7 in a
heated condition burus partially on the front grate 1 and finally reaches the back
grate 2 and there undergoes complete combustion.
The combustion gases from the back-grate 2 are consequently smokeless flames
by which the smoke produced on the front grate 1 is completely consumed, and
in this way combustion is rendered perfectly smokeless.
9 are windows arranged at the sides of the combustion chamber 7 for the inspec-
tion of the furnaces.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A smoke consuming furnace comprising an inclined front grate another con-
siderably narrower back grate arranged on a slightly lower plane and sloping

page_text: down towards the front an opening being left between the free ends of the two
grates which can be closed by a valve or bars for the purpose of removing the slag
the roof of the combustion chamber rising in the same direction as the front-grate
and slightly converging with the latter towards the shaft of the filling hopper so
that the combustion chamber is highest near the flue for combustion gases sub-
stantially as described.
2. The combination and arrangement of parts constituting the complete smoke
consuming furnace substantially as described and illustrated in the accompany-
ing drawings.
