- To all whom iii-may concern:
vvolving Kilns for Be it known that I, SvnN EMIL SIEURIN, a subject of the King of Sweden and Norway, residing at Hoganas, Sweden, have invented certain new and useful Improvements in Re- Generating of Gas and Roasting; and I do hereby declare thefollowing to be a full, clear, and exact descri tion of the invention, such as will enable others-skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
y invention relates to improvements in kilns for the generation of gas or for roasting ores; and it consists in providing a stationary charger adapted to feed the material to be acted upon into a rotating inclined kiln provided with partition-walls having openings therein so disposed to each other as to term a spiral path for the fuel or material to be roasted as it v medium of travels from the mouth to the outlet. m
The invention also consists in a blast at the opposite end of the kiln to that of the materia.-inlet, so that a volume of air injected into or of gases generated in the kiln. is caused to travel in a direction opposite to that of the path of the fuel or material to be roasted, said air or gases bein through the the partitions and t eir openings, compelled to pass through and not only above the fuel or material being roasted.
The invention further consists in means {3i regulating the discharge of fuel from the In the annexed drawings I have illustrated a constructional form of apparatus for the generation of gas, in which- Figure 1 is a longitudinal section of an apparatus embodying my invention; Fig. 2, a cross-section on the line 2 2; Fig. 1.
a designates a cylindrical kiln made of or lined with a fire roof material and provided with bearing-rel s a, resting on ant1frictionrollers c, which are mounted on a suitable support. The kiln may be rotated by any suitable means, such as that shown in Fig. 1, which consists of abeveled gear a surrounding the kiln, in mesh with a bevel-gear p on a shaft p, which may be able source of power.
The fuel or material to be roasted is fed to the kiln through a hopper b, a suitable gastight connection (if being provided for condriven from any suitnecting the two parts, said hop er having a charging-aperture provided wit a valve to prevent the escape of gas therefrom, a suitable gas-outlet 0 being provided for with drawing the gas. I
An air-blast e is connected w th the kiln opposite the feed-ho per, a blast-box f being formed by means 0' and an extension h, which latter extends down into a water seal in an ash-pit 'L. The air is injected into the blast box, and from there it is forced through a perforated plate 17. into the kiln.
In order to obtain a long layer of fuel, the kiln is divided into compartments by part1- tion-Walls Z, in which are formed 0 en ngs m, so disposed relatively to each ot or that a spiral path is formed for the material as it passes through the kiln. By this arrangement the gases are compelied to pass through and not only above the layer of fuel, as would be the case if the kiln were not provided with the partition-walls. A more complete stirring of the fuel is aiso attalned by this arrangement, and new reaction-surfaces of the fuel will constantly come in the way of the gases. if'granulated fuel is used, the partition walls prevent it from lumping, and a long layer of fuel is obtained.
The ashes resulting from the combustion of the fuel in the kiln are discharged through a door k in the perfotated' plate a. g
it is obvious that the material in the kiln cannot to any important degree fall out through the perforations these perforations are to be adaptedto the material used.
The operation of the apparatus when. employed for the generation of gas is as follows: The hopper is filled with the gas generating hr the roastin re uisite fuel, t ough' the charging-a erture, anal the valve b is then closed. he fuel having been ignited, the kiln is set in motion and the air-blast turned on. The air entering through the erforations in the plate n is driven through t e kiln in a direction opposite to the direction of travel of the material, which latter is; by gravity and the rotation of the kiln, gradually fed through the openings in the partitions and may be discharged through the door it.
I claim 1. In an apparatus of the character specified, the combination with a rotary kiln, of means for supplying fuel into one end of the material, together with the.
of the plate n, as i IIO latter, means to inject air into the opposite end of the same, a plurality of transverse partitions in said kiln having openings arranged to form a prolonged passa e for said air and fuel passing throu h the ki 11.
2. In. an a paratus of t e character specifled, the com mation-With a rotary kiln, of a stationary hopper adapted tov supply fuel into one end oi the kiln, a blast-box mounted at the opposite end of the latter, an air-sup ply for said box, and a plurality of transverse partitions ments, each of said partitions having an opening so arranged relatively to the adjacent opening as to form a spiral passage for the fuel ande air.
3. In an-a paratus of the character specifled, the corn ination with an inclined rotary kiln, ofa stationary feed-hopper connected therewith at one end, a valved charging-port in said hop er, a gas-outlet port in the opper, an airlast connected with said kiln at the other end, a perforated plate in the lastmentioned end of said kiln, a plurality of dividing the, kiln into compart-- transverse partitions dividing the kiln into compartments, each of said partitions having an opening so arranged relatively to the adjacent opening vas to form a spiral passage throu h the kiln.
4. 11 an a paratus of the character specified, the com mation with an inclined cylindrical kiln, means to rotate .the same, a stationary'feed-hopper communicating With one end of the kiln and rovided with a chargingport, a valve in sai port, a gas-outlet port in the hopper, an ash-pit at the opposite end of the kiln, a blast-boxhaving an a1r-tight connection with the kiln and extending into. the ashit, an air-supply communicating with the last-box, a perforated endplatein the kiln, and a doorin said Y late;
In testimon that I claim the foregoing as my invention have signed my name in presence of two subscribin Witnesses.
