Isizathu esithe ngqo sokuba kutheni i-zirconia ilula ukonakalisa xa isithando somlilo sivaliwe kwaye siqaliswe kwakhona kukuba umphunga wamanzi kwi-flue gas uhlala kwi-probe ye-zirconia emva kokunyuswa emva kokuba isithando somlilo sivaliwe. Kulula ukulimaza intloko ye-ceramic zirconia. Uninzi lwabantu luyazi ukuba i-zirconia probe ayinakuchukumisa amanzi xa ishushu. Isakhiwo se-Nernst zirconia probe sihluke kwi-probe ye-zirconia eqhelekileyo, ngoko olu hlobo lwemeko aluyi kwenzeka.
I-zirconia probes ye-Nernst isetyenziswe kwizityalo ezininzi zamandla kunye nezityalo ezininzi zentsimbi kunye nezityalo zepetrochemical e-China, kunye ne-avareji yobomi benkonzo ye-4-5 iminyaka. Kwezinye izityalo zamandla, i-zirconia probes yachithwa kwaye yatshintshwa emva kokusetyenziswa iminyaka eyi-10. Ngokuqinisekileyo, inento yokwenza neemeko zezityalo zamandla kunye nomgangatho womgubo wamalahle kunye nokusetyenziswa okufanelekileyo.
Xa ulinganisa igesi, qaphela ukuhamba kwegesi yokulinganisa, kuba ukuhamba kwegesi yokulinganisa kuya kubangela ukuba ukushisa kwendawo ye-zirconium kuhla kwaye kubangele iimpazamo zokulinganisa.Ngenxa yokuba igesi yokulinganisa ayinakulawulwa kakuhle, ukuhamba kwegesi ioksijini esemgangathweni kwibhotile yoxinzelelo inokuba nkulu kakhulu. Ukongeza, imeko efanayo inokwenzeka xa umoya ocinezelweyo usetyenziselwa ukuhlanjululwa kwi-intanethi, ngakumbi xa umoya ocinezelweyo uqulethe amanzi. Ukushisa kweentloko ze-zirconia ezahlukeneyo ngexesha le-intanethi malunga ne-600-750 degrees. Iintloko ze-ceramic zirconia kule bushushu zibuthathaka kakhulu kwaye zonakaliswe lula. Emva kokuba ubushushu bendawo butshintshile okanye umswakama udibene, iintloko ze-zirconia ziya kuveliswa ngokukhawuleza I-Cracks, le yimbangela echanekileyo yokulimala kwentloko ye-zirconia.Nangona kunjalo, isakhiwo se-zirconia probe ye-Nernst sihluke kwi-probes ye-zirconia eqhelekileyo. Inokucocwa ngokuthe ngqo ngomoya ocinezelweyo kwi-intanethi kwaye inomlinganiselo omkhulu wokuhamba kwerhasi yokulinganisa ngaphandle kokonakalisa intloko ye-zirconium.
Ngenxa yokuba nayiphi na impahla ye-ceramic iyancipha kakhulu kwiqondo lokushisa eliphezulu, xa intloko ye-zirconium ichukumisa amanzi kwiqondo lokushisa eliphezulu, i-zirconia iya kutshatyalaliswa. Ngokungathandabuzekiyo le yingqiqo eqhelekileyo.Khawufane ucinge ukuba kwenzeka ntoni xa ubeka ikomityi yeceramic enobushushu obungama-700 degrees emanzini? Kakade ke, asikhuthazi abathengi ukuba benze iimvavanyo ezinjalo. Oku kubonisa ukuba i-zirconia probe yeNernst iyakwazi ukumelana namanzi kumaqondo obushushu aphezulu. Esi sisizathu esithe ngqo sobomi obude benkonzo ye-Nernst's zirconia probes.
Ngenxa yokuba intloko ye-zirconia yinto ye-ceramic, zonke izinto ze-ceramic kufuneka zilawule inkqubo yokutshintsha ubushushu ngokomothuko we-thermal (i-coefficient yokwandisa impahla xa ubushushu butshintsha) izinto ziya konakaliswa.Ngoko ke, i-probe kufuneka ifakwe ngokuthe ngcembe kwindawo yokufakela i-flue xa itshintsha kwi-intanethi.Nangona kunjalo, i-Nernst zirconia probe inokumelana nokutshatyalaliswa kwe-thermal. Xa ubushushu be-flue bungaphantsi kwe-600C, bunokuthi tye ngaphakathi nangaphandle ngaphandle kwempembelelo kwi-probe ye-zirconia.Oku kuququzelela kakhulu ukutshintshwa kwe-intanethi yabasebenzisi. Oku kukwangqina ukuthembeka kweNernst zirconia probe.
Ngenxa yokuba ulwakhiwo lwe-Nernst zirconia probe lwahlukile kwiiprobe ze-zirconia eziqhelekileyo, lusenokusebenza ngokuqhelekileyo xa amacala omabini e-probe egugile. Nangona kunjalo, ukuba i-probe ifunyenwe igugile, i-sleeve ekhuselayo inokufakwa ngokulula, ukwenzela ukuba ubomi benkonzo yeprobe bunobude. Ngokuqhelekileyo, xa umgangatho wamalahle wesityalo sombane ulungile, unokusebenza. iminyaka emi-5-6 ngaphandle kokongeza umkhono okhuselayo. Nangona kunjalo, xa umgangatho wamalahle kwezinye izityalo zamandla ungalunganga okanye ukuhamba kwegesi ye-flue kukhulu kakhulu, i-Nernst zirconia probe inokufakwa lula kunye nomkhono okhuselayo ukulibazisa ixesha lokunxiba. Ngokuqhelekileyo, ukulibaziseka kwexesha lokunxiba kunokwandiswa malunga namaxesha e-3 emva kokongeza umkhono wokukhusela.
Ngenxa yobuninzi bokuvuza komoya kwi-gas saver, ukuba i-zirconia probe ifakwe emva komgcini wegesi, ukuvuza komoya we-gas saver kuya kubangela iimpazamo ekuchanekeni komlinganiselo we-oxygen kwi-flue. Enyanisweni, abaqulunqi bamandla bonke bafuna ukufaka i-zirconia probe ngokusondeleyo phambi kombhobho ngokusemandleni.Ngokomzekelo, emva komkhombe we-flue, ukusondela kwi-flue yangaphambili, impembelelo encinci yokuvuza komoya, kwaye iphezulu ukuchaneka kwe-oksijini. umlinganiselo. Nangona kunjalo, i-zirconia probes eziqhelekileyo azikwazi ukumelana nobushushu obuphezulu be-500-600C, kuba xa iqondo lokushisa liphezulu, inxalenye yokutywinwa kwentloko ye-zirconium kulula ukuvuza (isizathu sokwahlukana okukhulu phakathi kwe-coefficient yokwandisa i-thermal yensimbi kunye ne-ceramic) , kwaye xa ubushushu be-ambient buphezulu kune-600C , Kuya kuvelisa iimpazamo ngexesha lokulinganisa, kwaye intloko ye-zirconia nayo ilula kakhulu ukuba yonakaliswe ngenxa yokutshatyalaliswa kwe-thermal. iiprobes apho ubushushu bomkhuhlane bungaphantsi kwama-600C. Nangona kunjalo, i-Nernst zirconia probe kunye ne-heater inokumelana nokushisa okuphezulu kwe-900C, engaphuculi nje ukuchaneka komlinganiselo womxholo we-oksijeni, kodwa yandisa kakhulu ubomi benkonzo ye-zirconia probe.
Inkunkuma yasezidolophini yeyona ndlela yonyango yenzululwazi kunye neyonga amandla ngokutshisa ukuvelisa umbane. Nangona kunjalo, ngenxa yokuba ukubunjwa kwenkunkuma kuyinkimbinkimbi kakhulu, ukwenzela ukuba kuqinisekiswe ukutsha kwayo ngokupheleleyo kunye nokunciphisa ukungcoliseka kwendalo ngexesha lokukhutshwa kwegesi ye-flue, umxholo we-oksijini kwinkqubo yokutsha uphezulu kune-boilers yamalahle okanye i-oyile, eyenza amacandelo ahlukeneyo ane-asidi kwigesi ye-flue ukwanda.Ukongezelela, kukho izinto ezinobumuncu kunye namanzi kwinkunkuma, ukwenzela ukuba i-hydrofluoric acid eyingozi kakhulu iya kuveliswa emva kokuba inkunkuma itshiswe. Ngeli xesha, ukuba i-zirconia probe ifakwe kwindawo apho ubushushu be-flue ambient buphantsi kakhulu (300-400C), i-tube yensimbi engenasici ye-probe iya kubola ngexesha elifutshane. Ukongezelela, umswakama kwi-flue gas inokuhlala lula kwintloko ye-zirconia kwaye yonakalise intloko ye-zirconia.
I-Nernst's zirconia probe ingasetyenziselwa ukulinganisa ioksijini kwiimeko ezahlukeneyo. I-zirconia yayo ye-in-line probe ingasetyenziselwa ubushushu be-furnace ephezulu ye-1400C, kunye neyona nto iphantsi kwe-oksijini enokuthi ilinganiswe yi-10 minus 30 amandla (0.0000000000000000000000000000000000000000000000000000000000000000000000001%) .Ifanelekile ngokupheleleyo kwi-powder metal sintering.
