Iindaba

Ukuba ukhangela izixhobo zokugquma ubushushu obuphezulu ezilinganisa ukuqina, ukusebenza kakuhle kwamandla, kunye nokuguquguquka, izitena ezikhaphukhaphu ze-mullite lukhetho lwakho olufanelekileyo. Ngokungafaniyo nezitena zesiqhelo ezinzima, ezi zixhobo zihamba phambili zigqwesa kwiimeko ezahlukeneyo zemizi-mveliso-enkosi kubuninzi bazo obuphantsi, ukuzinza kwe-thermal, kunye nokuchasana okunamandla kwi-thermal shock. Apha ngezantsi, sicalula usetyenziso olungundoqo lwezitena ezikhaphukhaphu ze-mullite kuwo wonke amashishini angundoqo, sikunceda ukuba uqonde indlela abasombulula ngayo eyona mingeni icinezelayo yokugquma.

1. Usetyenziso olungundoqo: ILining yeSithando soBubushushu obuphezulu (iMetallurgy kunye noNyango loBushushu)

Izityalo zeMetallurgical kunye neendawo zokunyanga ubushushu zixhomekeke kwiziko elisebenza ku-1200–1600°C (2192–2912°F)—kwaye izitena ezikhaphukhaphu ze-mullite ziyindlela yokubeka ezi nkqubo zibalulekileyo.

Iimeko zesicelo:Ilayini yeziko lokutshisa, iziko ezenza lukhuni, kunye neziko lokutshisa intsimbi, i-aluminiyam, kunye nokulungiswa kwentsimbi engeyiyo intsimbi.

Kutheni Isebenza:I-conductivity yabo ephantsi ye-thermal (≤0.6 W / (m·K) kwi-1000 ° C) iyanciphisa ukulahleka kobushushu ukuya kuthi ga kwi-30% xa kuthelekiswa nezitena eziqhelekileyo eziphikisayo, ukunciphisa iindleko zepetroli kakhulu. Ukongeza, ukuxhathisa kwabo okuphezulu (akukho deformation phantsi kobushushu bexesha elide) kuqinisekisa ubomi beziko leminyaka emi-5-8, ukunciphisa ixesha lokuphumla.

2. Kubalulekile kwiCeramic & Glass Kilns

Ukudubula kwe-Ceramic kunye nokunyibilika kweglasi kufuna ulawulo oluchanekileyo lobushushu (1300-1550 ° C) kunye nokuchasana neegesi ze-oven corrosive. Izitena ze-mullite ezikhaphukhaphu zenziwe ngobunjineli ukuhlangabezana nezi mfuno:

IiKil zeCeramic:Isetyenziswa njengomgca wangaphakathi kwiitoni zetonela kunye nee-shuttle kilns. Ubunzima babo obuphantsi bobushushu buvumela imijikelo yokufudumeza / yokupholisa ngokukhawuleza (ukunciphisa ixesha lokudubula nge-15-20%), ukwandisa ukusebenza kakuhle kwemveliso yeethayile, izinto zococeko, kunye neeseramikhi zamashishini.

IiKilni zeglasi:Ifakwe kwisithsaba kunye nee-sidewalls zeglasi ezinyibilikayo. Umxholo wabo ophezulu we-alumina (i-65-75% i-Al₂O₃) ixhathisa ukukhukuliseka kwiglasi etyhidiweyo kunye nomphunga we-alkaline, ukuthintela ukungcoliswa kweemveliso zeglasi. Oku kuqinisekisa umgangatho weglasi ongaguqukiyo kwaye kwandisa ubomi benkonzo ye-kiln nge-2-3 iminyaka

3. I-Thermal Insulation kwiPetrochemical & Chemical Reactors

Izityalo ze-Petrochemical (umzekelo, i-ethylene crackers) kunye neekhemikhali ze-reactors zisebenza phantsi kweemeko ezinzima: amaqondo okushisa aphezulu (1000-1400 ° C) kunye neendawo ezinobungozi bemichiza. Izitena ze-mullite ezikhaphukhaphu zibonelela nge-insulation ethembekileyo apha:

Ukugqunywa kweReactor:Isetyenziswa njenge-backup insulation ye-reformer reactors kunye ne-catalytic crackers. I-porosity yabo evaliweyo (≤20% ukufunxwa kwamanzi) kuthintela ukungena kolwelo/iigesi ezidliwayo, ukukhusela iqokobhe lentsimbi yereactor ekudlekeni.

Imibhobho kunye nokugqunywa kombhobho:Ijikelezwe ngemibhobho yobushushu obuphezulu (umzekelo, leyo ithwele i-oyile eshushu okanye i-syngas) ukugcina ubushushu obumanzi kunye nokuthintela ukulahleka kobushushu. Oku akuphuculi ukusebenza kakuhle kwenkqubo kuphela kodwa konyusa ukhuseleko kwindawo yokusebenza ngokunciphisa amaqondo obushushu angaphezulu kombhobho

4. ICandelo eliPhambili kuMandla aVuselelekayo (iSolar Thermal & Biomass).

Njengoko ihlabathi litshintshela kumandla avuselelekayo, izitena ze-mullite ezikhaphukhaphu zidlala indima ebalulekileyo kwiinkqubo zamandla obushushu obuphezulu:

IZityalo zaMandla oMbane weSolar:Ifakwe kwiitanki zokugcina ityuwa enyibilikisiweyo kunye nezamkeli, ezigcina ubushushu kwi-565 ° C ukwenzela ukuvelisa umbane. Uzinzo lwabo lwe-thermal luqinisekisa ukuba akukho kuthotywa phantsi kokufudumeza / ukupholisa kwe-cyclic, ngelixa uxinano oluphantsi lunciphisa umthwalo owenziweyo weetanki zokugcina.

Iibhoyila zeBiomass:Isetyenziswa njenge-insulation kumagumbi okutsha kunye ne-flue gas ducts. Baxhathisa ukudumba kothuthu kunye nomhlwa ovela kumafutha e-biomass (umzekelo, iitshiphusi zokhuni, iindiza), ukuqinisekisa ukusebenza kakuhle kwebhoyila kunye nokunciphisa iindleko zokuyigcina.

5. Ukusetyenziswa okuKhethekileyo: ILebhu kunye ne-Aerospace High-Temp Isixhobo

Ngaphandle komlinganiselo wemizi-mveliso, izitena ze-mullite ezikhaphukhaphu zithenjwa kwizicelo ezichanekileyo:

Iziko leLebhu:Ifakwe kwiziko le-muffle kunye neetyhubhu zokuvavanya izinto eziphathekayo (umzekelo, uphando lwe-ceramic, uhlalutyo lwe-alloy yesinyithi). Ukuhanjiswa kwabo kwe-thermal efanayo (ukuhluka kobushushu ≤± 5 ° C) kuqinisekisa iziphumo zovavanyo ezichanekileyo.

Uvavanyo lwe-Aerospace:Isetyenziswa kumaziko ovavanyo lomhlaba kumacandelo enjini yejethi. Ziyakwazi ukumelana namaqondo obushushu aphezulu okwexeshana elifutshane (ukuya kuthi ga kwi-1800°C) ebudeni bovavanyo lokudinwa kwe-injini, nto leyo ebonisa ukugquma okuthembekileyo kumagumbi ovavanyo.
