Improvements in or relating to Smelting Furnaces.
I, ANDREAS SPIES, of Siegen, Germany, Manufacture do hereby declare the
nature of this invention to be as follows:-
This invention relates to an apparatus applied to smelting furnaces by means
of which an almost perfect combustion of the gases given off in the smelting
operation 18 effected and in consequence a considerable economy of fuel
The apparatus is illustrated in the accompanying drawing Figures 1 and 2
section and plan respectively Its operation is as follows
The gases given off in the smelting operation pass from the furnace a (the
mouth of which is closed by a cover b which serves at the same time for closing
the front of the furnace) into the receptacle surrounding the first mentioned
Owing to the shock imparted to the gases rising vertically at the cover b their
velocity is retarded
The gases pressing out of the lower part hereby become condensed and thus
increase the quantity of gas exposed to combustion thus generating a higher tem-
perature in the interior of the furnace
This
The receptacle a contains one or more sieves nots, or screens d arranged hori-
zontally obliquely or vertically which are moistened all over with water
water reaches the sieve in running out of several nozzles arranged on the reser-
voir or pipe e When the burning gases reach the sieve, which is constantly
cooled by water, they are prevented, by the considerable degree of cooling which
occurs, from striking through it in a burning state
The non-combustible part of the gases only escapes through the wire net or
sieve after the combustion of the gases has taken place
As experiments have proved the gases which pass through the wire nething
contain no combustible matter of any kind.
I, ANDREAS SPIES, of Siegen, Germany, Manufacturer. 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 apparatus is illustrated in the diawing accompanying my Piovisional
Specification in which Figures 1 and 2 are section and plan respectively Its
operation is as follows: The gases given off in the smelting operation pass
fiom the furnace a (the mouth of which is closed by a cover which serves at
the same time for closing the front of the furnace) into the receptacle e surround-
ing the first mentioned
This
The receptacle e contains one or more Bieves, nets, on screens & alianged hori-
zontally, obliquely or vertically which are moistened all over with water
water caches the sieve in running out of several nozzles arranged on the reset-
voi on pipe When the burning gases reach the sieve, which 18 constantly
cooled by water, they are prevented by the considerable degree of cooling which
occurs, from striking through it in a burning state
The non-combustible part of the gases only escapes through the wie net or
Bieve after the combustion of the gases has taken place.
As experiments have proved the gases which pass through the wue netting
contain no combustible matter of any kind.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim 18:-
1 Smelting furnace, the distinguishing feature of which 18 that for the pur-
pose of ensuring more perfect combustion before the gases pass out into the open
air, one or more sieves, nets, screens, or the like moistened with water, and
thereby cooled, are arranged, which prevent the flame from striking through.
consequently further the process of combustion in the interior of the furnace, and
effect an economy of fuel, as set forth
2. A modification of the invention as claimed in Claim 1, the distinguishing
feature being that, in cupola furnaces, the eyes nets, screens, or the like,
which prevent the flame from striking through, are arranged horizontally,
obliquely, or vertically. substantially as set forth
