Mu nganda aho ubushyuhe bukabije buhora ari ikibazo gikomeye, guhitamo ibikoresho birwanya ubushyuhe bishobora gutuma imikorere irushaho kuba myiza, umutekano, ndetse no kugabanya ikiguzi. Siruko ifite alumina nyinshi irwanya ubwivumbure Igaragara nk'igikoresho cy'ifatizo, cyakozwe kugira ngo gihangane n'ubushyuhe bwinshi, isuri n'ingufu. Waba uri mu bucukuzi bw'ibyuma, ibumba, ikora ibirahure, cyangwa ikindi gice gisaba guhuza ubushyuhe, iyi morti yihariye itanga imikorere idasanzwe idashobora guhurirana n'izindi. Reka turebe impamvu morti igabanya alumina nyinshi ari yo ihitamo rikomeye mu gukoresha ubushyuhe bwinshi ku isi.
Mbere na mbere, sima nini irwanya alumina irakomeye mu gukoresha ibyuma, aho ubushyuhe bukunze kuzamuka hejuru ya 1500°C. Mu nganda z'ibyuma, ikoreshwa cyane mu guhuza amatafari arwanya alumina mu itanura riturika, amatafari, amatafari ya tundishes, n'amatanura y'amashanyarazi. Ingano nyinshi ya alumina (ubusanzwe 70% kugeza 90%) irayifasha kudashonga cyane, ikarinda gushonga cyangwa guhinduka ndetse no mu gihe cy'ubushyuhe bwinshi bw'icyuma gishongeshejwe. Byongeye kandi, irwanya ingese ituruka ku ifu ishongeshejwe, okiside z'ibyuma, n'ibindi bintu bikunze gukoreshwa mu gukora ibyuma. Uku kuramba kugabanya igihe cyo kudakora neza giterwa no kudakora neza, bigatuma ikora neza kandi ikagabanya ikiguzi cyo kubungabunga ibyuma.
Inganda zikora ibumba n'ibirahuri nazo zishingira cyane ku gikoresho kinini cya alumina gishyushye. Amatanura ya keramike, akoreshwa mu gutwika ibumba, amatafari, n'amatanura agezweho, akora ku bushyuhe buri hagati ya 1200°C na 1800°C. Igikoresho kinini cya alumina gitanga isano ikomeye kandi idahindagurika ku gikoresho cya refractory muri aya matanura, bigakomeza imiterere yayo ndetse no mu gihe cyo gushyushya no gukonjesha kenshi. Ku matanura ashongesha ikirahure, aho ubushyuhe burenze 1600°C, ikirenge cya mortike kirwanya ubushyuhe ni ingenzi cyane. Kirinda kwangirika no kwangirika guterwa n'ihindagurika ryihuse ry'ubushyuhe, kikongera igihe cyo kubaho cy'amatanura kandi kigakomeza ubwiza bw'ibirahure. Bitandukanye n'amatanura make ya alumina, ntabwo ikora iyo ishongesha ikirahure, yirinda kwanduzanya kwangiza ibirahure byinshi.
Indi shingiro ikoreshwa mu nganda zitanga ingufu za peteroli n'izishyuha. Mu byuma bitanga umuriro, mu byuma bitwika, no mu byuma bivugurura, ibice bigabanya ubushyuhe bwinshi bya alumina bihuza n'ibice bishyuha cyane, imyuka ihumanya, n'ibikomoka kuri lisansi n'ibindi bikomoka kuri lisansi. Mu nganda zikoresha amakara, yihanganira imiterere y'ivu ry'ibisiga n'ingaruka za okiside za sulfur. Mu byuma bishyuha bya peteroli n'ibivugurura, irwanya kwangirika kwa hydrocarbon n'umwuka ushyuha cyane, bigatuma ingufu zitangwa neza kandi mu buryo bwizewe. Imiterere yayo myiza yo gufatana ituma kandi iba nziza mu gusana insinga zangiritse, ikagabanya igihe cyo kudakora no kongera igihe cyo gukoresha ibikoresho by'ingenzi.
Uretse izi nganda z'ingenzi, sima ifite alumina nyinshi ikoreshwa mu nganda zitwika imyanda, aho ikora ku bushyuhe bwinshi n'imyuka yangiza ikorwa n'imyanda yo mu mujyi no mu nganda. Ni ingenzi kandi mu nganda zikora ibikoresho byo gushushanya no gutwika ibyuma bikoreshwa mu gucura ibyuma. Uburyo bwo gukora ibintu butandukanye, hamwe no kudashyuha cyane no kuramba, bituma iba igisubizo rusange ku ikoreshwa ryose risaba ko habaho ubufatanye bwizewe mu bidukikije bishyuha cyane.
Mu guhitamo moteri ifite alumina nyinshi irwanya ubushyuhe, ni ngombwa guhitamo ibicuruzwa byiza kandi byujuje ibisabwa n'inganda. Shaka moteri ifite ingano ihoraho y'uduce, ifite gufatana gukomeye, kandi irwanya ubushyuhe cyane. Moteri yacu ifite alumina nyinshi irwanya ubushyuhe ikorwa hakoreshejwe ibikoresho fatizo byiza cyane n'uburyo bugezweho bwo kuyitunganya, bigatuma itanga umusaruro udasanzwe mu bikorwa bigoye cyane. Waba ukeneye gushyira mu itanura rinini ry'icyuma, gusana itanura rya ceramic, cyangwa kubungabunga boiler y'uruganda rutanga amashanyarazi, moteri yacu itanga icyizere n'igihe kirekire ukeneye kugira ngo imirimo yawe ikomeze gukora neza.
Ntugapfobye imikorere iyo bigeze ku gukoresha ubushyuhe bwinshi. Hitamo sima ifite alumina nyinshi irwanya ubushyuhe bwinshi, idakira ingese, kandi iramba. Twandikire uyu munsi kugira ngo umenye byinshi ku bicuruzwa byacu n'uburyo bishobora kongera imikorere yawe no kugabanya ikiguzi cyo kubibungabunga.
