Ama-nozzle e-ceramic e-silicon carbide (SiC)sezibe yizingxenye ezibalulekile ezinhlobonhlobo zezicelo zezimboni, ikakhulukazi emkhakheni wokususa igesi ephumayo (i-FGD). Lawa ma-nozzle aklanywe ngokucophelela ukuze amelane nezimo ezimbi kakhulu futhi afaneleka kahle ezindaweni lapho amazinga okushisa aphezulu nezinto ezibolayo zivame khona. Izakhiwo zawo ezihlukile, okuhlanganisa amandla aphezulu, ubulukhuni kanye nokumelana nokuguguleka nokugqwala, kuzenza zibe yisinqumo esingcono kakhulu sokuthuthukisa ukusebenza kahle kwezitshalo zamandla kanye nama-turbine egesi.
Ama-nozzle e-silicon carbide ceramic adlala indima ebalulekile enqubweni yokususa i-sulfurization ezitshalweni zikagesi. Umsebenzi oyinhloko walezi zinambuzane ukukhuthaza ukufafaza okufanayo kwe-ejenti yokususa i-sulfurization, okubalulekile ekunciphiseni ukukhishwa kwe-sulfur dioxide (SO2) kumagesi angcolile. Ukumelana nokushisa okuphezulu kwe-silicon carbide kwenza la ma-nozzle asebenze kahle ngaphansi kwezimo ezinzima ezivamile zezikhungo zokukhiqiza ugesi. Ngokuqinisekisa ukusatshalaliswa okufanayo kwe-ejenti yokususa i-sulfurization, la ma-nozzle athuthukisa kakhulu ukusebenza kahle kwe-desulfurization iyonke, ngaleyo ndlela anciphise kakhulu ukukhishwa kwamagesi angcolisayo.
Ukuqina kwama-nozzle e-silicon carbide kungenye inzuzo ebalulekile. Ezindaweni lapho izinto zendabuko zingawohloka ngokushesha ngenxa yokugqwala noma ukuguguleka, i-silicon carbide iyagqama ngenxa yokuphila kwayo isikhathi eside. Lokhu kuqina kusho izindleko zokulungisa eziphansi kanye nesikhathi esincane sokungasebenzi kwezitshalo zikagesi ngoba abaqhubi bangathembela kula ma-nozzle ukuthi aqhubeke nokusebenza isikhathi eside. Ukuze izitshalo zikagesi zilwele ukuhlangabezana nemithetho eqinile yezemvelo, ikhono lokugcina ubuqotho bokusebenza ngaphansi kwezimo ezinzima libalulekile.
Ngaphezu kwalokho, ukusetshenziswa kwama-nozzle e-silicon carbide kudlulela ngale kokususwa kwe-flue gas. Kuma-turbine egesi, la ma-nozzle asiza ukuhlanza amagesi ngaphambi kokuba angene ku-turbine. Ubulukhuni obuphezulu kanye namandla e-silicon carbide kwenza kube nokulawulwa okunembile kokugeleza kwegesi, kuqinisekiswe ukungcola okuncane. Le nqubo yokuhlanza ibalulekile ekusebenzeni kahle kwama-turbine egesi, njengoba isiza ukuvimbela umonakalo nokugcina amazinga okusebenza afanele. Ngokusebenzisa ama-nozzle e-silicon carbide, opharetha bangathuthukisa ukuthembeka nokusebenza kahle kwezinhlelo ze-turbine yegesi.
Ukuguquguquka kwama-nozzle e-silicon carbide ceramic kubonakala nasekhonweni lawo lokusebenza ezindaweni ezahlukahlukene zezimboni. Ngaphezu kokukhiqizwa kwamandla kanye nama-turbine egesi, la ma-nozzle angasetshenziswa nasekucubungulweni kwamakhemikhali, ukuphathwa kwemfucuza kanye neminye imikhakha edinga izinto zokusebenza okuphezulu. Ukumelana kwawo namakhemikhali kuwenza afaneleke ukusetshenziswa ezindaweni lapho kukhona khona izinto ezibolayo, okuqinisekisa ukuthi angakwazi ukumelana nobunzima bezinqubo ezahlukene zezimboni.
Ngaphezu kwezakhiwo zazo zemishini nezamakhemikhali, ama-nozzle e-silicon carbide nawo anegalelo ekusimeni kwemvelo. Ngokuthuthukisa ukusebenza kahle kwe-desulfurization kanye nokunciphisa ukukhishwa kwegesi, la ma-nozzle adlala indima ebalulekile ekusizeni imboni ukuthi ihambisane nemithethonqubo yezemvelo. Njengoba ukuqwashisa komhlaba wonke ngekhwalithi yomoya kanye nokulawulwa kokungcola kuqhubeka nokukhula, isidingo sezixazululo ezisebenzayo njenge-nozzle ze-ceramic ze-silicon carbide kulindeleke ukuthi sikhule. Amandla abo okukhuthaza imisebenzi ehlanzekile ahambisana nomgomo obanzi wokunciphisa umthelela wemvelo wemisebenzi yezimboni.
Ngamafuphi, ama-nozzle e-silicon carbide ceramic abaluleke kakhulu ekusetshenzisweni kwezimboni zesimanje, ikakhulukazi ekususeni i-flue gas kanye nokusebenza kwe-gas turbine. Amandla awo aphezulu ahlukile, ubulukhuni, ukumelana nokugqwala kanye nokumelana nokuguguleka kuzenza zibe zilungele ukuthuthukisa ukusebenza kahle kwezitshalo zamandla kanye nokunciphisa ukukhishwa kwegesi. Njengoba imboni iqhubeka nokubeka phambili ukusimama futhi ihambisana nezindinganiso zemvelo, indima yama-nozzle e-silicon carbide ngokungangabazeki izogqama kakhulu, ivule indlela yezinqubo zezimboni ezihlanzekile nezisebenza kahle.
