Silicon carbide (SiC) milomo ya ceramicakhala zigawo zikuluzikulu zosiyanasiyana ntchito mafakitale, makamaka m'munda wa flue gas desulfurization (FGD). Milomo imeneyi imapangidwa mosamala kwambiri kuti ipirire kwambiri ndipo imayenera kukhala ndi malo omwe kutentha kwambiri komanso zinthu zowononga zimachulukirachulukira. Makhalidwe awo apadera, kuphatikizapo mphamvu zambiri, kuuma ndi kuvala ndi kukana dzimbiri, amawapanga kukhala chisankho chabwino kwambiri chothandizira kuyendetsa bwino kwa magetsi ndi magetsi opangira mpweya.
Silicon carbide ceramic nozzles amagwira ntchito yofunika kwambiri pakuchotsa sulfurization m'mafakitale amagetsi. Ntchito yaikulu ya nozzles izi ndi kulimbikitsa kupopera mbewu mankhwalawa yunifolomu wa desulfurization agent, amene n'kofunika kwambiri kuchepetsa mpweya wa sulfure dioxide (SO2) mu mpweya wa flue. Kutentha kwapamwamba kwa silicon carbide kumathandizira kuti ma nozzles awa azigwira ntchito bwino m'malo ovuta omwe amapangira magetsi. Powonetsetsa kugawidwa kofanana kwa desulfurization agent, ma nozzles awa amathandizira kwambiri kutulutsa bwino kwa desulfurization, potero amachepetsa kwambiri kutulutsa kwa mpweya woipitsa.
Kukhalitsa kwa silicon carbide nozzles ndi mwayi wina wofunikira. M'malo omwe zida zachikhalidwe zimatha kuwonongeka mwachangu chifukwa cha dzimbiri kapena kuvala, silicon carbide imadziwika chifukwa cha moyo wake wautali wautumiki. Kukhalitsa kumeneku kumatanthauza kutsika kwa ndalama zokonzetsera komanso kuchepa kwa nthawi yocheperako kwa mafakitale opangira magetsi chifukwa ogwiritsa ntchito amatha kudalira ma nozzles awa kuti apitilize kugwira ntchito kwa nthawi yayitali. Kwa mafakitale amagetsi omwe akuyesetsa kukwaniritsa malamulo okhwima a chilengedwe, kuthekera kosunga umphumphu wogwira ntchito pansi pa zovuta ndizofunikira.
Kuphatikiza apo, kugwiritsa ntchito ma silicon carbide nozzles kumapitilira kutulutsa mpweya wa flue desulfurization. Mu makina opangira gasi, mphunozi zimathandiza kuyeretsa mpweya usanalowe mu turbine. Kuuma kwakukulu ndi kulimba kwa silicon carbide kumathandizira kuwongolera bwino kayendedwe ka gasi, kuwonetsetsa kuti zonyansa zochepa. Njira yoyeretserayi ndiyofunikira kuti ma turbines azigwira bwino ntchito, chifukwa zimathandiza kupewa kuwonongeka ndikusunga magwiridwe antchito abwino. Pogwiritsa ntchito ma silicon carbide nozzles, ogwira ntchito amatha kuwongolera kudalirika komanso kugwiritsa ntchito bwino makina amagetsi amagetsi.
Kusinthasintha kwa ma nozzles a silicon carbide ceramic nozzles kumawonekeranso pakutha kwawo kugwira ntchito m'malo osiyanasiyana ogulitsa. Kuphatikiza pa kupanga magetsi ndi ma turbine a gasi, ma nozzles awa amathanso kugwiritsidwa ntchito pokonza mankhwala, kuwongolera zinyalala ndi magawo ena omwe amafunikira zida zogwira ntchito kwambiri. Kukaniza kwawo kwamankhwala kumawapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo omwe zinthu zowononga zimakhalapo, kuwonetsetsa kuti zitha kupirira zovuta zamitundu yosiyanasiyana yamakampani.
Kuphatikiza pa machitidwe awo amakina ndi mankhwala, ma silicon carbide nozzles amathandizanso kuti chilengedwe chisasunthike. Pokonza bwino ntchito ya desulfurization ndi kuchepetsa mpweya, ma nozzleswa amathandiza kwambiri kuti makampani azitsatira malamulo a chilengedwe. Pomwe kuzindikira kwapadziko lonse lapansi zamtundu wa mpweya komanso kuwononga chilengedwe kukukulirakulira, kufunikira kwa mayankho ogwira mtima monga ma silicon carbide ceramic nozzles akuyembekezeka kukula. Kuthekera kwawo kulimbikitsa ntchito zoyeretsa kumagwirizana ndi cholinga chachikulu chochepetsera kukhudzidwa kwa chilengedwe ndi ntchito zamakampani.
Mwachidule, ma silicon carbide ceramic nozzles ndi ofunikira kwambiri pamafakitale amakono, makamaka pakuchotsa gasi wa flue desulfurization ndi turbine ya gasi. Kulimba kwawo kwapadera, kuuma kwawo, kukana dzimbiri komanso kukana kuvala kumawapangitsa kukhala abwino kuwongolera mphamvu zamafakitale amagetsi ndikuchepetsa kutulutsa mpweya. Pamene makampani akupitiriza kuika patsogolo kukhazikika komanso kutsata miyezo ya chilengedwe, ntchito ya silicon carbide nozzles mosakayika idzakhala yotchuka kwambiri, ndikutsegula njira yoyeretsa komanso yogwira ntchito bwino m'mafakitale.
