Kusamalira njira yolowera mpweya yozungulira mu uvuni wa CDQ coke

Gawo lothandizira la payipi ya mpweya wopendekeka limapangidwa ndi njerwa zosalimba, zomwe zimadulidwa ndi mzere umodzi kuti zithandizire katundu wa payipi ya pamwamba. Kutentha kumasintha pafupipafupi, ndipo fumbi la coke lomwe limalowetsedwa ndi mpweya wozungulira limasaka gawoli mwamphamvu. Chifukwa chake, dera la payipi ya mpweya wopendekeka limagwiritsa ntchito kukana kutentha ndi kukana kuwonongeka. Phiko la njerwa la Mullite-silicon carbide lolimba kwambiri komanso mphamvu yosinthasintha. Poganizira momwe ntchito ikuyendera pano, zotsatira zake sizoyenera, ndipo njerwa zina zothandizira m'dera la payipi ya mpweya wopendekeka wa CDQ zinasweka mkati mwa chaka chimodzi.

Pokonza njerwa zothandizira za njira yolowera mpweya, njira imodzi ndikugwiritsa ntchito njerwa zoyambirira za mullite-silicon carbide kuti zimangidwenso; njira ina ndikugwiritsa ntchito castable kuti zithire; njira yachitatu ndikugwiritsa ntchito mabuloko opangidwa kale omwe satha kutha kuti amangenso.

Njira yothira ya chotsukira imagwiritsa ntchito kuyika kwa anangula ndi nthiti zolimbitsa. Njerwa zotsala zitachotsedwa, zotsukira za aluminiyamu silicon carbide steel fiber castables zolimba komanso zosatha kugwiritsidwa ntchito zimagwiritsidwa ntchito pokonza. Pofuna kuthetsa kusakanikirana pakati pa njerwa ndi chotsukira, pamwamba pa njerwa yoyambirira imabowoledwa ndikukhazikika ndi maboluti okulitsa, ndipo kutalika kwina kwa zotsukira zachitsulo zosapanga dzimbiri za "Y" kumalumikizidwa kunja kwa maboluti okulitsa. Malo ogwirira ntchito ayenera kukhala 50mm. Choyipa chogwiritsa ntchito njira iyi makamaka ndichakuti chotsukira chimagwa chonse, zomwe zimapangitsa kuti njerwa zoyambazo ziwonongeke, zomwe sizingakhale bwino pakukonza pambuyo pake.
