I-substrate ye-honeycomb yensimbi iyinto eyisisekelo ye-honeycomb enezimbobo eyenziwe ngegobolondo lensimbi engagqwali kanye ne-foil ye-FeCrAl ehlanganisiwe ngenqubo yokushisela i-coil. Isetshenziswa kakhulu ukusekela izembozo ze-catalytic (Pt, Pd, Rh) noma isebenze njengezinto eziyinhloko zokushintshana kokushisa, ezisetshenziswa kabanzi ekuhlanzweni komoya ophumayo emotweni, ekwelapheni igesi engcolile yezimboni, ekuvikelweni kokushisa kwezindiza nakwezinye izinkambu.
Yakhiwe nge-foil ye-alloy ye-FeCrAl, i-substrate ye-honeycomb yensimbi inesakhiwo esiminyene, esifana ne-honeycomb eneziteshi ezincane ezifanayo—esebenza njenge-"catalytic reactor" yokuhlanzwa kwegesi yokukhipha umoya. Igcwele izembozo ze-catalytic kanye nezinsimbi ezinhle (Pt, Pd, Rh) futhi inokumelana okuhle kakhulu nokushisa okuphezulu, okuvumela ukusebenza okuzinzile ngaphansi kwamazinga okushisa aphezulu okukhipha umoya. Lapho igesi yokukhipha umoya eshisa kakhulu idlula kulezi ziteshi ezincane, ama-catalyst ensimbi amahle abangela ukusabela kwamakhemikhali okuguqula ukungcola okuyingozi kube izinto ezingenangozi, ngezimpendulo ezibalulekile ezilandelayo:
1. Ukushiswa kwe-carbon monoxide:2CO + O₂ = 2CO₂
2. Ukushiswa kwe-hydrocarbon:2CxHy + (2x+y/2)O₂ = 2xCO₂ + yH₂O
3. Ukunciphisa i-nitrogen oxide:2NOx = N₂+ xO₂
Ngokudluliselwa kokushisa okusheshayo, ingcindezi ephansi emhlane kanye nokumelana okunamandla kokudlidliza, isetshenziswa kabanzi ekuhlanzweni komoya ophuma ngokuzenzakalelayo kanye nokwelashwa kwegesi engcolile yezimboni.

1. Usayizi omncane (ububanzi obungu-30-50mm, ubude obungu-50-100mm, ubude obungu-200-300 cpsi):
Ama-UAV, amajeneretha aphathekayo, izinjini ezincane zasolwandle, imishini yezolimo emincane, ama-ATV namathuluzi kagesi aphathwayo (ukufakwa okuncane, ukungcola okuncane kokukhipha ugesi).
2. Usayizi ophakathi nendawo (ububanzi obungu-80-150mm, ubude obungu-100-200mm, ubude obungu-100-400 cpsi):
Izimoto zabagibeli, izimoto zezentengiselwano ezilula (ama-catalytic cores anezindlela ezintathu), izandisi ze-EV range, i-hybrid exhaust kanye nama-generator amancane ezimo eziphuthumayo (umfutho ophansi emhlane, ukushisa okusheshayo).
3. Ubukhulu obukhulu (ububanzi obungu-180-300mm, ubude obungu-200-400mm, ubude obungu-100-200 cpsi):
Amaloli athwala kanzima, izimoto zobunjiniyela, igesi engcolile yezimboni, ukukhishwa komoya ophuma emanzini, ukuhlanzwa kwegesi yomoya ophumayo kanye ne-incineration flue (umthamo omkhulu wokukhishwa komoya ophumayo).
4. Usayizi okhethekile owenziwe ngokwezifiso (ongajwayelekile, ububanzi obungu->300mm/>400mm ubude, 60-600 cpsi):
Ama-APU ezindiza, ukwelashwa nge-petrochemical, imibhoshongo yamakhemikhali, ama-turbine egesi kanye nezitofu ezishisa kakhulu (izimo ezinzima).
Yebo impela. Singenza ngezifiso izici eziningi njengoba kungezansi:
1. Usayizi Nokuma: Ububanzi obungenziwa ngezifiso (30mm ~ 500mm +), ubude (50mm ~ 400mm +), kanye nesimo (isiyingi esijwayelekile, izimo ezikhethekile ezingajwayelekile) ukuze kulingane izikhala ezahlukene zokufakwa kwemishini.
2. Ubuningi Beseli: Kungashintshwa kusuka ku-60 cpsi kuya ku-600 cpsi, kufanelana nezidingo ezahlukene zokuhlanzwa kanye nokulungisa izimo ezahlukahlukene zokusetshenziswa (imishini yamandla amancane, ukwelashwa kwegesi elahliwe yezimboni, izindiza).
3. Imininingwane Yezinto: Ubukhulu be-foil ye-alloy ye-FeCrAl (0.03~0.08mm) bungenziwa ngezifiso, futhi isilinganiso sokwakheka kwe-alloy (Cr: 18-22%, Al: 4-6%) singalungiswa ngokuya ngezimo zokusebenza.
4. Ukulayisha kwe-Catalyst: Inani lokulayisha elenziwe ngokwezifiso (5~20 g/L) kanye nesilinganiso sensimbi esihloniphekile se-Pt/Pd/Rh, esivumelana nezindinganiso ezahlukene zokuhlanzwa kokukhipha umoya kanye nezidingo zokusebenza kahle kwe-catalytic.
