Chigadziko chesimbi chehoneycomb chinhu chine maburi ehoneycomb chakagadzirwa nesimbi isina ngura uye corrugated FeCrAl alloy foil kuburikidza ne coil welding process. Chinonyanya kushandiswa kutsigira catalytic coatings (Pt, Pd, Rh) kana kushanda se thermal exchange core material, chinoshandiswa zvakanyanya mukuchenesa utsi hwemotokari, kurapwa kwemarara emaindasitiri, kudzivirira kupisa kwemhepo uye mimwe minda.
Yakagadzirwa kubva kuFeCrAl alloy foil, substrate yesimbi yemuzinga ine chimiro chakaita semuzinga ine migero midiki yakafanana—inoshanda se "catalytic reactor" yekuchenesa gasi remuzinga. Yakazadzwa nemidziyo ye catalytic uye simbi dzakanaka (Pt, Pd, Rh) uye ine simba rakanaka rekudzivirira kupisa kwakanyanya, zvichiita kuti ishande zvakanaka pasi pekupisa kwakanyanya. Kana gasi remuzinga rinopisa zvakanyanya richipfuura nemumigero midiki iyi, zvinokonzeresa makemikari zvinoshandura kusvibisa kunokuvadza kuita zvinhu zvisina njodzi, nezviito zvikuru zvinotevera:
1. Kuomeswa kwecarbon monoxide:2CO + O₂ = 2CO₂
2. Kuomeswa kweHydrocarbon:2CxHy + (2x+y/2)O₂ = 2xCO₂ + yH₂O
3. Kuderedza Nitrogen oxide:2NOx = N₂+ xO₂
Nekukurumidza kutamisa kupisa, kumanikidzwa kwemusana kwakaderera uye kuramba kwakasimba kwekuzunguzika, inoshandiswa zvakanyanya mukuchenesa utsi hwemotokari uye kugadzirisa magasi emarara emaindasitiri.

1. Diki (dhayamita ye30-50mm, kureba kwe50-100mm, 200-300 cpsi):
MaUAV, majenareta anotakurika, mainjini madiki emugungwa, michina midiki yekurima, maATV nematurusi emagetsi anobatwa nemaoko (kuisa diki, kusvibiswa kweutsi kushoma).
2. Hukuru hwepakati nepakati (dhayamita 80-150mm, kureba 100-200mm, 100-400 cpsi):
Mota dzinotakura vanhu, mota dzekutengesa dzakareruka (dzine nzira nhatu dzinoshandisa catalytic cores), EV range extenders, hybrid exhaust uye majenareta madiki e emergency (low pressure, fast heat-up).
3. Hukuru (dhayamita 180-300mm, kureba 200-400mm, 100-200 cpsi):
Marori anorema, mota dzeinjiniya, gasi remarara remumaindasitiri, utsi hwemugungwa, bhaira nekupisa gasi remuchina (huwandu hwakawanda hweutsi hwemuchina).
4. Yakagadziriswa saizi yakakosha (isina kurongeka, >300mm dhayamita/>400mm kureba, 60-600 cpsi):
Ma APU emuchadenga, kurapwa kwe petrochemical, matoweri emakemikari, ma turbine egasi uye maovheni anodziya zvakanyanya (mamiriro ezvinhu akaoma).
Ehe zvechokwadi. Tinogona kugadzirisa zvinhu zvakawanda sezviri pazasi:
1. Saizi & Chimiro: Dhayamita inogadziriswa (30mm~500mm+), kureba (50mm~400mm+), uye chimiro (chakatenderera, chisina kurongeka, chimiro chakakosha) kuti chikwane nzvimbo dzakasiyana dzekuisa michina.
2. Kuwanda kwemasero: Kunogona kugadziriswa kubva pa60 cpsi kusvika pa600 cpsi, zvichienderana nezvinodiwa zvakasiyana zvekucheneswa uye catalytic zvemhando dzakasiyana dzekushandiswa (midziyo midiki yemagetsi, kurapwa kwemagasi emaindasitiri, ndege).
3. Magadzirirwo Ezvinhu: Ukobvu hwefoiri yeFeCrAl alloy (0.03~0.08mm) hunogona kugadziriswa, uye chiyero chekuumbwa kwealloy (Cr: 18-22%, Al: 4-6%) chinogona kugadziriswa zvichienderana nemamiriro ekushanda.
4. Kurodha kweCatalyst: Huwandu hwekutakura hunogona kugadziriswa (5~20 g/L) uye chiyero chesimbi chakanaka chePt/Pd/Rh, zvichienderana nezvinodiwa zvakasiyana zvekuchenesa utsi uye zvinodiwa zvekushanda zvakanaka kwecatalytic.
