Uma ufuna izinto zokuvikela ukushisa eziphakeme ezilinganisela ukuqina, ukusebenza kahle kwamandla, kanye nokuguquguquka, izitini ze-mullite ezilula ziyisinqumo sakho esifanele. Ngokungafani nezitini zendabuko ezisindayo eziqinile, lezi zinto ezithuthukisiwe ziphumelela kakhulu ezimweni ezahlukahlukene zezimboni—ngenxa yobuningi bazo obuphansi, ukuzinza okuhle kakhulu kokushisa, kanye nokumelana okunamandla nokushaqeka kokushisa. Ngezansi, sichaza ukusetshenziswa okubalulekile kwezitini ze-mullite ezilula kuzo zonke izimboni eziyinhloko, sikusiza ukuthi uqonde ukuthi zixazulula kanjani izinselelo zakho zokuvikela ukushisa ezicindezela kakhulu.
1. Ukusetshenziswa Okuyinhloko: Ulwelwesi Lwesithando Esishisa Kakhulu (Ukwelashwa Ngensimbi Nokushisa)
Izitshalo zensimbi kanye nezindawo zokwelapha ukushisa zithembele ezithandweni ezisebenza ku-1200–1600°C (2192–2912°F)—futhi izitini ze-mullite ezilula yizona ezisetshenziswa kakhulu ekufakeni lezi zinhlelo ezibalulekile.
Izimo Zokusebenza:Ukufakwa kwendwangu yezithando zokuqinisa, izithando zokuqinisa, kanye nezithando zokushisa zensimbi, i-aluminium, kanye nokucubungula insimbi okungeyona i-ferrous.
Kungani Kusebenza:Ukushisa kwazo okuphansi (≤0.6 W/(m·K) ku-1000°C) kunciphisa ukulahleka kokushisa ngamaphesenti afinyelela ku-30 uma kuqhathaniswa nezitini ezijwayelekile ezimelana nokushisa, kunciphisa kakhulu izindleko zikaphethiloli. Ngaphezu kwalokho, ukumelana kwazo okuphezulu kokukhukhuleka (akukho ukuguquguquka ngaphansi kwamazinga okushisa aphezulu isikhathi eside) kuqinisekisa impilo yesithando somlilo yeminyaka engu-5-8, kunciphisa isikhathi sokungasebenzi kokulungisa.
2. Okubalulekile Ezitsheni Zokushisela Ze-Ceramic Nezingilazi
Ukushisa nge-ceramic nokuncibilika kwengilazi kudinga ukulawulwa okuqondile kokushisa (1300–1550°C) kanye nokumelana namagesi e-oven agqwalisayo. Izitini ze-mullite ezilula zenzelwe ukuhlangabezana nalezi zidingo:
Izitofu Zobumba:Zisetshenziswa njengendwangu yangaphakathi yama-tunnel kiln nama-shuttle kiln. Ubunzima bazo obuphansi bokushisa buvumela imijikelezo yokushisa/yokupholisa esheshayo (kunciphisa isikhathi sokudubula ngo-15-20%), kukhulisa ukusebenza kahle kokukhiqiza kwama-tile, izinto zangasese, kanye nezinto zobumba zezimboni.
Izitsha Zokushisela Ingilazi:Ifakwe umqhele kanye nezindonga ezisemaceleni zezitofu ezincibilikisa ingilazi. Okuqukethwe kwazo okuphezulu kwe-alumina (65–75% Al₂O₃) kumelana nokuguguleka okuvela engilazini encibilikisiwe kanye nomhwamuko we-alkaline, kuvimbela ukungcoliswa kwemikhiqizo yengilazi. Lokhu kuqinisekisa ikhwalithi yengilazi eqhubekayo futhi kwandisa impilo yesevisi yesitofu ngeminyaka engu-2-3.
3. Ukufakwa Kwe-Thermal ku-Petrochemical & Chemical Reactors
Izitshalo ze-Petrochemical (isb., ama-ethylene crackers) kanye nama-chemical reactor asebenza ngaphansi kwezimo ezimbi kakhulu: amazinga okushisa aphezulu (1000–1400°C) kanye nezindawo zamakhemikhali ezinamandla. Izitini ze-mullite ezilula zinikeza ukuvikela okuthembekile lapha:
Ukufakwa Kwe-Reactor:Isetshenziswa njengokuvikela ukuvikela ama-reactor ashintshayo kanye nama-cracker e-catalytic. Ama-porosity awo avaliwe (≤20% ukumuncwa kwamanzi) avimbela ukungena koketshezi/amagesi agqwalisayo, okuvikela igobolondo lensimbi le-reactor ekugqwaleni.
Ukufakwa Kwepayipi Nokumbozwa Kwepayipi:Kuhlanganiswe ngamapayipi okushisa okuphezulu (isb. lawo athwala uwoyela oshisayo noma ama-syngas) ukuze kulondolozwe izinga lokushisa eliwuketshezi futhi kuvinjelwe ukulahleka kokushisa. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kwenqubo kodwa futhi kuthuthukisa ukuphepha emsebenzini ngokunciphisa izinga lokushisa elingaphezulu kwamapayipi.
4. Ingxenye Eyinhloko Yamandla Avuselelekayo (Ukushisa Kwelanga kanye Ne-Biomass)
Njengoba umhlaba uguqukela emandleni avuselelekayo, izitini ze-mullite ezilula zidlala indima ebalulekile ezinhlelweni zamandla ezishisa kakhulu:
Izitshalo Zamandla Okushisa Elanga:Ifakwe ematangini okugcina usawoti oncibilikisiwe kanye nama-receiver, agcina ukushisa ku-565°C ukuze kukhiqizwe ugesi. Ukuqina kwawo kokushisa kuqinisekisa ukuthi akukho ukuwohloka ngaphansi kokushisa/ukupholisa okujikelezayo, kuyilapho ubuningi obuphansi bunciphisa umthwalo wesakhiwo samatangi okugcina.
Ama-Biomass Boilers:Isetshenziswa njengokuvikela amakamelo okushisa kanye nemigudu yegesi yomoya. Iyamelana nokufakwa komlotha kanye nokugqwala okuvela kumafutha e-biomass (isb., ama-wood chips, utshani), ukuqinisekisa ukusebenza kahle kwebhoyila kanye nokunciphisa izindleko zokulungisa.
5. Ukusetshenziswa Okukhethekile: Imishini Yelebhu Neyezindiza Enokushisa Okuphezulu
Ngaphandle kwesilinganiso sezimboni, izitini ze-mullite ezilula zithembeke ekusetshenzisweni okunembile:
Izitofu Zelebhu:Zifakwe ngaphakathi kwezithando zomlilo kanye nezithando zamapayipi ukuze zihlolwe izinto (isb. ucwaningo lwe-ceramic, ukuhlaziywa kwe-alloy yensimbi). Ukusatshalaliswa kwazo kokushisa okufanayo (ukwehluka kwezinga lokushisa ≤±5°C) kuqinisekisa imiphumela yokuhlolwa enembile.
Ukuhlolwa Kwezindiza:Isetshenziswa ezindaweni zokuhlola phansi zezingxenye zenjini yejethi. Zimelana namazinga okushisa aphezulu kakhulu esikhashana (kufika ku-1800°C) ngesikhathi sokuhlolwa kokushiswa kwenjini, okuhlinzeka ngokuvikela okuthembekile kwamakamelo okuhlola.
