Description
Vlrom the standnipes A andi2 are Wlhl'llflllllf tUGTJ'StUS HALL, 0F NEW YORK, N. Y.
lpecification of Letters Patent.
Application filed Oc'toecr l0, 19M.
lPatented Det. mi, i913,
serial no. 725.623.
To all whom, 'it may conce/m:
lie it known that l, WILLIMI ilrGUsTUs linnn, a citizen of the United States, and resident olf New York, Y., have invented a certain new and useful improvement in Furnaces, of which the itollogwiug.f le a specilication.
This invention has for its object to provide a lurnace ior use in decomposing pyrites and metallic sulfide and producing sulfurcted hydrogen or (and) sulfur directly therefrom, whereby the sulfide, while in the furnace, may bc subjected to the action of steam and of a reducing Haine, preferably alternately.
The invention is illustrated in the accompanyingdrawings in tvliichr- Figure l is -a part elevation, part vertical section, and Fig'. '2 is a horizontal section, of a mechanical furnace iittcd with my improvements.
Referring to the drawings, sets of standpipes such. as indicated il, tlf, il? are disposed around the furnace proper, the standpipes A being each supplied, by means of a pipe B, with steam or Water vapor from a suitable source; the standpipes A beingl supplied, by means oi a pipe B', with gas from a gas producer or the like, and the standpipes il being ea ch supplied with air from a suitable source, as for instance from an air compressor by means oit a pipe B2.
Alirona the standpipes il, pipes C supplying through 'the nozzles C. led pipes D and E "or supplying reducing gas steam or Water 'vapor extend furnace Wall and terminate 1n 1 and air, respectively, each oi said pipes prei erably terminating in an extension l? which asses into the furnace Wall and terminates in a nozzle FZ i A lgroup ci noaalce G,.F are disposed just above each shell a: oli the furnace and are arranged to supply the necessary steam, and the gas and air by ignition oit which is produced the necessary reducing dame to act directly on the pyrites or metallic sulfide as they are moved aroundthe Shelves by rakes 'a' or the like. The eatension l*1 increases in diameter toward the outer Wall of the furnace, as shown, so as to assist in producing an intimate mixture of gas and air.A The nozzles F are also preferably each provided with a Wire gauze screen or iilter sGr, and, to permit of easy removal, are ait-ranged to lit loosely in the furnace Wall and 'to be tamped in with clay.
i the shelves,
its shown, and as preferred, each pipe TE is nrrauyged coaxially of the extension F, while the pipe ly this arrangement,the air passinirthrough the pipes Ll produces au injector-like action on the gas from the standpipe il. il.. rota-V table louver ll with openings adapte-d to register with openings on the extension li is, provided on said extension for the admission ot additional air iii desired.
The pyritcs or metallic sulfide are fed in at l, and, enveloped in the atmosphere of reducing flame and steam, pass around and 'tall on to successive shelves a, being finally discharged, at Y) from the lowermost shelf. rlhe sulituretetfi hydrogen or sulfur or both together pass ofi by way oi" thc discharge pipe lil.
Valves arc fitted at X so as to permit regu-lation ofthe amount oi steam, gas, and air supplied to the various shelves. By means ot' properly adjusting these valves, any desired conditions of'reductivity of the grasos in contact with the ore on the various shelves can be maintained. ln prac tice l preler to maintain a more highly reducing atmosphere, in the upper compare mentsthan in the lower compartments. By`
suitable regulation of the air, gas and steam connections, l can produce any dcsiredconditions as to reduction` oxidation or nere' trality in this respect7V in each of the several compartments into which the furnace is divided, accordingr to the process in which the furnace is tobe employed.
By the arrangement above described, the pyrites or metallic sulfide, as they are carried around the shelves a: bytho relies a' or the like, may be subjected to the action ot steam and oi a reducing Home.
It will be understood that where l relier in the claims to Water vapor l intend to include steam.
Having described my invention what l'. claim and desire to secure by Letters Patr ent ot the United States is :-V
metallic sulfids shelves, over 'which comprising Superposed the pyrites or sulfide are caused to travel on 'their downward course, rotatable stirrers disposed `adjacent and connections for introduc ing steam and for introducing gas and air into each ol'- the several compartments, an
independently operable means tor regulating the' relative amounts of stealth-gas and D meets it at righ-t angles,
air introduced to each of said compartments.
f2. A furnace for-decomposing pyrites or n'xetallic sulfids comprising superposed shelves, over which the pyrites or suliids are caused to travel on their downward course, ronxtahle stirrers disposed adjacent the shelves, and connections for introducing steam and for introducing gas and air, into at least a plurality of the several compartments, and independently operable means for regulating the relative amounts of steam, gas and air introduced to each of said plurality of compartments.
A furnace for decomposing pyrites or metallic sulfids comprising super' osed shelves, over which the pyrites or sulfi s are caused to travel on their downward course, rotatable stirrers disposed adjacent thc shelves, connections terminating in the vicinity of and above the Shelves for introducing Water vapor and gas and air into the interior of the furnace, and means for controlling the supply of the steam and of the gas and air to the inlets adjacent the various shelves.
4. A furnace for decomposing pyrites or metallic sulfids comprising superposed substantially horizontal shelves, over which the pyrites or sulfids are caused to travel on their downward course, and connections for introducing steam and for introducing gas and air, into each of the several compartments, and independently operable means for regulating the relative amounts of steam, gas and air introduced to each of said compartments.`
In testimony whereof I have signed my naine to this specification in the presence of two subscribing Witnesses.
