Mu musaruro w’inganda n’ikoreshwa ry’ingufu, gucunga ubushyuhe bukabije mu gihe hakorwa ibishoboka byose kugira ngo imikorere irusheho kuba myiza kandi igire umutekano ni ikibazo gikomeye kuri bose.Uburingiti bwa fibre ya ceramic, ibikoresho birwanya ubushyuhe bwinshi kandi bikingira ubushyuhe, byagaragaye nk'ikintu cyahinduye byinshi mu gukemura ibi bibazo. Kubera ko birwanya ubushyuhe cyane, ubushyuhe buke, ubworoherane, kandi biramba, byabaye igisubizo cy'ingenzi mu nzego zitandukanye. Iyi nkuru irasuzuma ikoreshwa ry'uburyo butandukanye bwo gupfuka imyenda ya ceramic, igaragaza impamvu ari amahitamo meza ku bigo bishaka ubushyuhe bwizewe.
Urwego rw'inganda n'itanura niho uburingiti bwa fibre ya ceramic bugaragara cyane. Inganda nka sima, ibyuma, n'imiti zishingikiriza ku matanura n'amatanura bikora ku bushyuhe burenga 1000°C. Nta bushyuhe buhagije butuma ubushyuhe bwinshi bugabanuka cyane, lisansi ikoreshwa cyane, ndetse n'ingaruka mbi zishobora guterwa n'ibikoresho byo hanze bishyushye cyane. Uburingiti bwa fibre ya ceramic, iyo bushyizwe mu buryo bwo gukingira cyangwa gukingira inyuma kuri izi mashini zishyushya cyane, butanga imbogamizi nziza ku bushyuhe bugabanya ubushyuhe. Urugero, uruganda rwa sima rwagaragaje ko rwagabanutseho 10% buri kwezi mu ikoreshwa rya lisansi ndetse n'ubushyuhe bwo hejuru bwa 60°C nyuma yo gukoresha ubushyuhe bwa fibre ya ceramic. Iboneka mu byiciro bishobora kwihanganira ubushyuhe bwa 1600°C, igumana ubuziranenge bw'imiterere yayo n'imikorere yayo yo gukingira ndetse no mu gihe kirekire ikoreshwa mu bushyuhe bwinshi, bigatuma iba nziza ku matanura ya sima, amatanura ashyushya ibyuma, n'amatanura akoresha imiti.
Inganda zikora peteroli, gaze n'amashanyarazi zungukira cyane ku ruhare rw'ubudodo bwa fibre ya ceramic mu gukingira imiyoboro. Imiyoboro y'umwuka, imiyoboro y'amavuta ashyushye, n'uburyo bwo gushyushya bisaba kubungabunga ubushyuhe buringaniye kugira ngo hirindwe ubukonje buringaniye no kwangirika kw'imiyoboro. Ubuhanga bwo koroshya no guhuza neza kwa fibre ya ceramic bituma ipfunyika neza imiyoboro y'uburebure bwose, igakora urwego rwo gukingira rudahindagurika rugabanya ubushyuhe bugabanuka kugeza munsi ya 5% mu bihe byinshi. Ikora kandi nk'imbogamizi ku bushuhe n'ibintu byangiza, yongera igihe cyo kubaho k'imiyoboro. Mu nganda zitanga amashanyarazi, ikoreshwa cyane mu gukingira inkuta z'amaboiler, imiyoboro y'amazi, na sisitemu za turbine, mu gihe mu nganda zikora peteroli, irinda imiyoboro ikora ubushyuhe bwinshi, ikora neza kandi neza. Imiterere yayo yoroheje kandi igabanya umutwaro rusange ku nyubako z'imiyoboro, byoroshya kuyishyiraho no kuyibungabunga.
Inganda z'ubwubatsi zikomeje gukoresha uburingiti bwa fibre ya ceramic kugira ngo buhuze n'amahame akomeye agenga umutekano w'inkongi no gukoresha neza ingufu. Nk'igikoresho kidashya, ni cyiza cyane mu kongera ubushobozi bwo kurwanya inkongi z'umuriro ku nkuta, ibisenge, n'inzugi z'umuriro. Mu gihe habayeho inkongi, ikora uruzitiro rugabanya ikwirakwira ry'umuriro, bigatanga umwanya w'ingirakamaro wo kwimuka. Byongeye kandi, imiterere yayo ifite imyenge itanga ubushobozi bwo kurinda urusaku, bigatuma ikoreshwa mu bitaro, amashuri, n'amahoteli aho kugenzura urusaku ari ingenzi cyane. Iyo ikoreshejwe mu kurinda inkuta hanze, igabanya ubushyuhe hagati y'ibidukikije byo mu nzu no hanze, ikongera ubushobozi bwo gukoresha ingufu mu nyubako no guhuza n'inyubako zigezweho. Uburingiti bwa fibre ya ceramic bugezweho nabwo ni bwiza ku bidukikije, nta bintu byangiza, butuma habaho umutekano mu gushyira mu bikorwa ahantu hatuwe.
Uretse izi nzego z'ingenzi, uburingiti bwa fibre ya ceramic bukoreshwa nk'igisubizo cy'ingirakamaro mu nzego zihariye. Mu buhanga bw'ibyuma, bukora inzitizi z'igihe gito zo kurinda ibyuma mu gihe cyo gutwika kugira ngo hirindwe ko ibyuma bishongeshwa. Mu nganda zikora indege n'imodoka, ubushobozi bwabwo bworoshye kandi burwanya ubushyuhe bwinshi butuma buba bwiza mu gukingira ibice bishyuha cyane. Ndetse no mu nganda zikora ingufu za kirimbuzi, uburingiti bwa fibre ya ceramic bwakozwe mu buryo bwihariye (nk'icyitegererezo cya JAF-200) buhangana n'imirasire myinshi n'impanuka za LOCA nta kwangiza imikorere, burinda insinga n'ibikoresho by'ingenzi. Ku bakunda ibintu bigezweho n'abanyabukorikori bato, bukoreshwa mu matanura yo mu rugo, mu byuma bicukurwamo ibyuma, no mu ziko zicana inkwi, butanga uburyo bwo kwirinda ubushyuhe mu buryo bwizewe kandi bunoze.
Igitandukanya igitambaro cya fibre ya ceramic n'ibikoresho bisanzwe byo gushyushya ni uburyo kidasanzwe gihuza imikorere yacyo n'uburyo gikoreshwa. Uburyo bwo gushishamo urushinge rufite impande ebyiri butuma habaho urusobe rw'imigozi itatu rutuma imbaraga zo gukurura no kurwanya ingese, mu gihe ingano yacyo nke y'ibishishwa bitanga ubushobozi bwo gutwara ubushyuhe buhoraho. Gisaba kubungabungwa gake, kigabanya ikiguzi cy'ingufu cyane mu gihe cyose kimaze, kandi cyoroshye gukata no gushyiraho, ndetse no mu myanya mito. Byaba ari mu mishinga minini y'inganda cyangwa mu mishinga mito, igitambaro cya fibre ya ceramic kigendana n'ibikenewe bitandukanye hamwe n'ingano n'imiterere yabyo.
Mu gusoza, uburyo bwo gukora ibintu bitandukanye, kuramba, no kuzigama ingufu bituma iba igikoresho cy'ingenzi mu nganda. Kuva ku mashyiga y'inganda kugeza ku nyubako zo guturamo, kuva ku byuma bitwara ikirere kugeza ku ngufu za kirimbuzi, itanga ubushyuhe bwizewe butuma habaho umutekano, kunoza imikorere, no kugabanya ikiguzi cy'imikorere. Ku bigo n'inzobere bashaka uburyo bwo gushyushya bujyanye n'ibyo bakenera mu nganda zigezweho, ubushyuhe bujyanye n'ibyo bakenera ni bwo buryo bwiza bwo guhitamo. Shora imari muri ubu buryo bwo gushyushya bujyanye n'ibyo bakenera uyu munsi kandi wibonere itandukaniro mu byo bakoresha mu bushyuhe bwinshi.
