Icyuma gikoreshwa mu gusudira ibinyabiziga ni ibikoresho by'ibanze bifite imyenge y'ibinyabiziga bikozwe mu gikonoshwa cy'icyuma kitagira umugese n'urupapuro rwa FeCrAl rukozwe mu buryo bwo gusudira ibinyabiziga. Bikoreshwa cyane cyane mu gushyigikira irangi rya catalytic (Pt, Pd, Rh) cyangwa gukora nk'ibikoresho by'ibanze byo gukwirakwiza ubushyuhe, bikoreshwa cyane mu gusukura imyuka ihumanya y'imodoka, gutunganya imyuka ihumanya ikirere, kurinda ubushyuhe bw'ikirere n'ibindi bikorwa.
Yakozwe mu ifuru ya FeCrAl, igice cy'icyuma cy'ubuki gifite imiterere ikomeye, isa n'ubuki ifite imiyoboro mito isa—ikora nk'"icyuma gitunganya imyuka isohora umwuka." Irimo imyuka isohora umwuka n'ibyuma byiza (Pt, Pd, Rh) kandi ifite ubushobozi bwo kurwanya ubushyuhe bwinshi, bigatuma ikora neza mu gihe cy'ubushyuhe bukabije. Iyo imyuka isohora umwuka ikoresha ubushyuhe bwinshi inyuze muri iyi miyoboro mito, imyuka myiza y'icyuma itera ingaruka mbi zihindura imyanda mibi mo ibintu bitangiza, hamwe n'ingaruka zikomeye zikurikira:
1. Kugabanya umwuka wa monoxide ya karuboni:2CO + O₂ = 2CO₂
2. Kugabanya imyuka ya hydrocarbon:2CxHy + (2x + y / 2) O₂ = 2xCO₂ + yH₂O
3. Kugabanya ogisijeni ya azote:2NOx = N₂+ xO₂
Kubera ko ubushyuhe bwihuta, umuvuduko muke w'umugongo ndetse no kudahindagurika cyane, ikoreshwa cyane mu gutunganya imyuka ihumanya ikirere no gutunganya imyuka ihumanya ikirere mu nganda.

1. Ingano nto (umurambararo wa mm 30-50, uburebure bwa mm 50-100, cpsi 200-300):
UAV, moteri zitwara imizigo, moteri nto zo mu mazi, imashini nto z’ubuhinzi, ATV n’ibikoresho by’amashanyarazi bikoreshwa mu ntoki (gushyiraho ibintu bito, umwanda muke uturuka mu byuka).
2. Ingano iringaniye (umurambararo wa mm 80-150, uburebure bwa mm 100-200, 100-400 cpsi):
Imodoka zitwara abagenzi, imodoka zoroheje z’ubucuruzi (zifite inzira eshatu zo gukaragaza), ibyuma bitanga amashanyarazi, imashini zisohora umwotsi zivanze n’imashini nto zitanga amashanyarazi (umuvuduko muke w’umugongo, ubushyuhe bwihuse).
3. Ingano nini (umurambararo wa mm 180-300, uburebure bwa mm 200-400, 100-200 cpsi):
Amakamyo akomeye, imodoka z’ubuhanga, imyuka ihumanya ikirere, imyuka ihumanya ikirere yo mu mazi, imyuka isukura icyuma gishyushya n’iy’umuriro (ingano nini y’imyuka isohoka).
4. Ingano yihariye yihariye (idasanzwe, >300mm diameter />400mm uburebure, 60-600 cpsi):
APU z’ikirere, uburyo bwo kuvura peteroli, iminara y’ibinyabutabire, turbine za gaze n’amatanura ashyushye cyane (imimerere mibi).
Yego rwose. Dushobora guhindura ibintu byinshi nk'uko bikurikira:
1. Ingano n'imiterere: Ingano y'umurambararo (30mm ~ 500mm +), uburebure (50mm ~ 400mm +), n'imiterere (uruziga rusanzwe, imiterere yihariye idasa) kugira ngo ihuze n'ahantu hatandukanye ho gushyira ibikoresho.
2. Ubucucike bw'uturemangingo: Ishobora guhindurwa kuva kuri cpsi 60 kugeza kuri cpsi 600, ijyanye n'ibisabwa bitandukanye byo gusukura no gukamura ibintu mu buryo butandukanye (ibikoresho bito by'amashanyarazi, gutunganya imyuka ihumanya ikirere mu nganda, indege).
3. Ibisobanuro by'ibikoresho: Ubunini bwa aluminiyumu ya FeCrAl (0.03 ~ 0.08mm) bushobora guhindurwa, kandi igipimo cy'imiterere ya aluminiyumu (Cr: 18-22%, Al: 4-6%) gishobora guhindurwa hashingiwe ku miterere y'akazi.
4. Gushyiramo ibikoresho bya Catalyst: Ingano y'ibikoresho bishobora guhindurwa (5 ~ 20 g / L) n'ikigereranyo cya Pt / Pd / Rh cy'icyuma cyiza, bihuye n'amahame atandukanye yo gusukura umwotsi n'ibikenewe mu gukoresha neza ibikoresho bya catalyst.
