Kugwiritsa ntchito kwakukulu kwa silicon carbide ceramic nozzles

Ma nozzle a ceramic a Silicon Carbide (SiC)zakhala zigawo zofunika kwambiri m'mafakitale osiyanasiyana, makamaka pankhani yochotsa mpweya woipa (FGD). Ma nozzles awa adapangidwa mosamala kuti athe kupirira mikhalidwe yovuta kwambiri ndipo ndi oyenera malo omwe kutentha kwambiri ndi zinthu zowononga zimapezeka kwambiri. Makhalidwe awo apadera, kuphatikizapo mphamvu yayikulu, kuuma, komanso kukana kuwonongeka ndi dzimbiri, zimapangitsa kuti akhale chisankho chabwino kwambiri chowongolera magwiridwe antchito a magetsi ndi ma turbine a gasi.

Ma nozzle a ceramic a silicon carbide amagwira ntchito yofunika kwambiri pa njira yochotsera sulfur m'mafakitale opanga magetsi. Ntchito yayikulu ya ma nozzle awa ndikulimbikitsa kupopera kofanana kwa mankhwala ochotsera sulfur, zomwe ndizofunikira kwambiri pochepetsa kutulutsa kwa sulfur dioxide (SO2) mu mpweya wotuluka. Kukana kutentha kwambiri kwa silicon carbide kumathandiza kuti ma nozzle awa azigwira ntchito bwino pansi pa mikhalidwe yovuta yomwe imachitika m'malo opangira magetsi. Poonetsetsa kuti mankhwala ochotsera sulfur amafalikira mofanana, ma nozzle awa amathandizira kwambiri ntchito yonse yochotsera sulfur, motero amachepetsa kwambiri kutulutsa kwa mpweya woipitsa.

Kulimba kwa ma nozzle a silicon carbide ndi ubwino wina waukulu. M'malo omwe zipangizo zachikhalidwe zimatha kuwonongeka mwachangu chifukwa cha dzimbiri kapena kuwonongeka, silicon carbide imadziwika chifukwa cha nthawi yayitali yogwira ntchito. Kulimba kumeneku kumatanthauza kuti ndalama zochepa zosamalira ndi nthawi yochepa yogwira ntchito yamagetsi chifukwa ogwiritsa ntchito amatha kudalira ma nozzle awa kuti apitirize kugwira ntchito kwa nthawi yayitali. Kuti mafakitale amphamvu akwaniritse malamulo okhwima okhudza chilengedwe, kuthekera kosunga umphumphu wa ntchito pansi pa zovuta ndikofunikira.

Kuphatikiza apo, kugwiritsa ntchito ma nozzles a silicon carbide kumapitirira kuchotsedwa kwa mpweya wofewa. Mu ma turbine a gasi, ma nozzles awa amathandiza kuyeretsa mpweya asanalowe mu turbine. Kulimba kwambiri ndi mphamvu ya silicon carbide zimathandiza kuwongolera bwino kayendedwe ka mpweya, kuonetsetsa kuti palibe zinyalala zambiri. Njira yoyeretsera iyi ndi yofunika kwambiri kuti ma turbine a gasi azigwira ntchito bwino, chifukwa imathandiza kupewa kuwonongeka ndikusunga magwiridwe antchito abwino. Pogwiritsa ntchito ma nozzles a silicon carbide, ogwiritsa ntchito amatha kupititsa patsogolo kudalirika ndi magwiridwe antchito a makina a turbine a gasi.

Kusinthasintha kwa ma nozzle a ceramic a silicon carbide kumawonekeranso mu kuthekera kwawo kugwira ntchito m'malo osiyanasiyana amafakitale. Kuwonjezera pa kupanga magetsi ndi ma turbine a gasi, ma nozzle awa angagwiritsidwenso ntchito pokonza mankhwala, kukonza zinyalala ndi madera ena omwe amafunikira zipangizo zogwira ntchito kwambiri. Kukana kwawo mankhwala kumapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'malo omwe pali zinthu zowononga, kuonetsetsa kuti amatha kupirira zovuta za njira zosiyanasiyana zamafakitale.

Kuwonjezera pa mphamvu zawo zamakina ndi mankhwala, ma nozzle a silicon carbide amathandizanso kuti chilengedwe chikhale cholimba. Mwa kupititsa patsogolo ntchito yochotsa sulfurization komanso kuchepetsa mpweya woipa, ma nozzle awa amathandiza kwambiri makampani kutsatira malamulo okhudza chilengedwe. Pamene chidziwitso cha padziko lonse cha ubwino wa mpweya ndi kuwongolera kuipitsa chilengedwe chikupitirirabe, kufunikira kwa mayankho ogwira mtima monga ma nozzle a ceramic a silicon carbide kukuyembekezeka kukula. Kuthekera kwawo kulimbikitsa ntchito zoyera kukugwirizana ndi cholinga chachikulu chochepetsera kuwononga chilengedwe kwa ntchito zamafakitale.

Mwachidule, ma nozzles a silicon carbide ceramic ndi ofunikira kwambiri pamafakitale amakono, makamaka pakuchotsa sulfurization ya mpweya wofewa komanso kugwiritsa ntchito turbine ya gasi. Mphamvu zawo zapadera, kuuma, kukana dzimbiri komanso kukana kukalamba zimapangitsa kuti zikhale zabwino kwambiri pakukweza magwiridwe antchito amagetsi komanso kuchepetsa mpweya woipa. Pamene mafakitale akupitilizabe kuyika patsogolo kukhazikika ndikutsatira miyezo ya chilengedwe, ntchito ya ma nozzles a silicon carbide mosakayikira idzawonekera kwambiri, ndikutsegulira njira njira zamafakitale zoyera komanso zogwira mtima.
