Pofuna kupanga mphamvu zoyera, mafakitale opanga magetsi akugwiritsa ntchito ukadaulo wapamwamba kwambiri kuti achepetse kuwononga chilengedwe. Chimodzi mwa ukadaulo uwu ndi kugwiritsa ntchito makina ochotsera mpweya wa flue gas (FGD), omwe amathandiza kwambiri kuchepetsa kutulutsa kwa sulfur dioxide. Pakati pa makinawa pali ma nozzles a FGD silicon carbide, omwe amapangidwa kuchokera ku zinthu zamakono zotchedwa silicon carbide. Blog iyi ifufuza kufunika kwa ma nozzles awa, kusintha kwa kapangidwe kake, komanso momwe amakhudzira kukhazikika kwa chilengedwe.
Ma nozzle a silicon carbide apangidwa kuti athandize njira yochotsera sulfur mu mafakitale amagetsi. Ntchito yawo yayikulu ndikuchotsa sulfure dioxide (SO2) ndi zinthu zina zowononga kuchokera ku mpweya wotuluka womwe umatuluka panthawi yoyaka mafuta, makamaka malasha. Kufunika kwa njirayi sikunganyalanyazidwe, chifukwa sulfure dioxide ndi yomwe imayambitsa kwambiri mvula ya asidi ndi mpweya woipa, zomwe zitha kukhala ndi zotsatirapo zoyipa pa thanzi la anthu komanso chilengedwe. Pogwiritsa ntchito ma nozzle a silicon carbide a FGD, mafakitale amagetsi amatha kuchepetsa kwambiri mpweya woipa ndikutsatira malamulo okhwima okhudza chilengedwe.
Mapangidwe a ma nozzle a FGD silicon carbide amapangidwira kuti azitha kugwira bwino ntchito zawo m'njira zosiyanasiyana. Mitundu iwiri yodziwika bwino ya nozzle yomwe imagwiritsidwa ntchito mumakina ochotsera sulfurization ndi spiral full cone nozzle ndi vortex hollow cone nozzle. Nozzle ya spiral full cone idapangidwa kuti ipange utsi wochepa wa madzi otulutsa, zomwe zimathandizira kukhudzana pakati pa madzi ndi mpweya wa flue, motero zimawonjezera magwiridwe antchito a njira yochotsera sulfurization. Komano, vortex hollow cone nozzle imapanga mawonekedwe ozungulira a spray omwe amagawa bwino mpweya wotulutsa flue, kuonetsetsa kuti mpweya wa flue ukugwira bwino ntchito. Kusankha mitundu iyi ya nozzle kumadalira zofunikira zenizeni za malo opangira magetsi ndi mawonekedwe a mpweya wa flue womwe ukukonzedwa.
Chimodzi mwa zabwino zazikulu za silicon carbide ngati chipangizo cha nozzle cha FGD ndi kulimba kwake kwabwino komanso kukana kuwonongeka ndi dzimbiri. Malo opangira magetsi nthawi zambiri amagwira ntchito pansi pa mikhalidwe yovuta, yokhala ndi kutentha kwambiri komanso tinthu tomwe timayabwa mu mpweya wa flue. Ma nozzle a silicon carbide amatha kupirira malo ovuta awa, kuonetsetsa kuti ntchito yayitali komanso kuchepetsa ndalama zosamalira. Kulimba kumeneku sikungowonjezera magwiridwe antchito a njira yochotsera sulfure, komanso kumathandizanso kukulitsa kudalirika kwa ntchito za malo opangira magetsi.
Kuwonjezera pa kuchotsa sulfur, ma nozzle a FGD SiC amakhalanso ndi gawo pa kuchotsa nitrification ndi fumbi. Mpweya wotuluka m'malo opangira magetsi opangidwa ndi malasha suli ndi sulfur dioxide yokha, komanso nitrogen oxides (NOx) ndi tinthu tating'onoting'ono. Mwa kuphatikiza machitidwe a FGD ndi ukadaulo wa denitrification, malo opangira magetsi amatha kuchiza zoipitsa zambiri nthawi imodzi, zomwe zimapangitsa kuti mpweya ukhale wabwino. Kutha kuthana ndi zoipitsa zosiyanasiyanazi ndikofunikira kwambiri kuti tikwaniritse miyezo ya chilengedwe ndikuchepetsa kuchuluka kwa mpweya woipa womwe umapezeka chifukwa cha kupanga mphamvu.
Zotsatira za chilengedwe pogwiritsa ntchito ma nozzles a FGD silicon carbide ndi zazikulu kwambiri. Popanda kuyeretsa bwino komanso kuyeretsa bwino, mpweya wochokera ku flue kuchokera ku magetsi ungayambitse kuipitsa mpweya kwambiri, zomwe zimayambitsa matenda opuma komanso kuwonongeka kwa chilengedwe. Kuphatikiza apo, mpweya wosasefedwa wochokera ku magetsi opangidwa ndi malasha ukhoza kuwononga zigawo za ma turbine a gasi m'makina oyendera magetsi, zomwe zimapangitsa kuti akonze zinthu zokwera mtengo komanso kuti ntchito zisayende bwino. Mwa kuyika ndalama muukadaulo wapamwamba wa FGD, magetsi sangangoteteza chilengedwe, komanso angawongolere magwiridwe antchito awo komanso kuti zinthu ziyende bwino.
Pamene mphamvu padziko lonse lapansi zikupita patsogolo, kufunika kwa magwero amphamvu oyera komanso okhazikika kukuchulukirachulukira. Ma nozzle a FGD silicon carbide ndi gawo lofunikira kwambiri pakusintha kupanga mphamvu zobiriwira. Mwa kuchotsa bwino zinthu zoipitsa mpweya woipa kuchokera ku mpweya wotuluka m'madzi, ma nozzle awa amathandiza mafakitale amagetsi kukwaniritsa zofunikira za malamulo ndikuthandizira kuti dziko lapansi likhale lathanzi. Pamene ukadaulo ukupita patsogolo komanso kufunika kwa kusamalira zachilengedwe kukupitirira kukula, ntchito ya ma nozzle a FGD silicon carbide polimbana ndi kuipitsidwa kwa mpweya ndi kusintha kwa nyengo mosakayikira idzakhala yofunika kwambiri.
Mwachidule, FGD Silicon Carbide Nozzle ndi chinthu chofunikira kwambiri pa ntchito yochotsa sulfure m'malo opangira magetsi. Kapangidwe kake kapadera, kulimba kwake, komanso kugwira ntchito bwino pochotsa sulfure dioxide ndi zinthu zina zoipitsa mpweya zimapangitsa kuti ikhale chinthu chofunikira kwambiri pakupanga mphamvu zoyera. Pamene malo opangira magetsi akupitiliza kugwiritsa ntchito ukadaulo wapamwamba kuti achepetse kuwonongeka kwa chilengedwe, kufunika kwa FGD Silicon Carbide Nozzles kudzangowonjezeka, zomwe zimapanga njira yopezera tsogolo lokhazikika.
