Lapho bephishekela ukukhiqizwa kwamandla okuhlanza, izitshalo zamandla ziye zamukela ubuchwepheshe obuthuthukile ukuze banciphise umthelela wabo wezemvelo. Olunye lwalezi zibuchwepheshe ukusetshenziswa kwezinhlelo ze-flue suselfurization (FGD), ezidlala indima ebalulekile ekunciphiseni ukuphuma kwe-sulfur dioxide ukuphuma. Enhliziyweni yalezi zinhlelo kukhona ama-nozzles we-FGD silicon Carbide nozzles, adalulwa ngokuzisika komphetho okubanjiwe okubizwa nge-silicon Carbide. Le bhulogi izohlola ukubaluleka kwalezi zezinhlanga, izinguquko zazo zokuqamba, kanye nomthelela wazo ekusimeni kwemvelo.
I-Silicon Carbide nozzles yenzelwe ukwenza lula inqubo yokusungula izitshalo zamandla. Umsebenzi wabo oyinhloko ukususa i-sulphur dioxide (SO2) nokunye ukungcoliswa okungcolile okuvela kumagesi we-flue akhishwe ngesikhathi sokuhlanganiswa kwamafutha okugcwala, ikakhulukazi amalahle. Ukubaluleka kwale nqubo akunakweqiwa ngokweqile, njengoba i-sulphur dioxide ingumthelela omkhulu emvuleni ye-acid nokungcoliswa komoya, okungaba nemiphumela emibi empilweni yomuntu kanye nemvelo. Ngokusebenzisa ama-nozzles we-FGD silicon Carbide nozzles, izitshalo zamandla zinganciphisa kakhulu ukuphuma kokuphuma futhi zihambisane nemithetho eqinile yezemvelo.
Imiklamo ye-FGD Silicon Carbide Nozzles yenzelwe ukwengeza ukusebenza kwayo ezinhlobonhlobo zezicelo. Izinhlobo ezimbili ezivamile ze-nozzle ezisetshenziselwa izinhlelo zokusungula ama-deselfurization ziyi-Spiral Full Nozzle kanye ne-Vortex Holes Cone Nozzle. I-Spiral Full Cone Nozzle yakhelwe ukukhiqiza inkungu enhle yoketshezi olungenamafuphi, oluthuthukisa ukuxhumana phakathi koketshezi kanye negesi ye-flue, ngaleyo ndlela kwandise ukusebenza kahle kwenqubo yokususelana. Ngakolunye uhlangothi i-vortex azzle nozzle, ngakolunye uhlangothi, ikhiqiza iphethini yokufafaza eshibhile esabalalisa kangcono ukumunca, ukuqinisekisa ukwelashwa okuphelele kwegesi ye-flue. Ukukhethwa kwalezi zinhlobo ze-nozzle kuncike kwizidingo ezithile zesikhungo samandla kanye nezimpawu zophethiloli opholile ophathwayo.
Enye yezinzuzo eziphambili zeSilicon Carbide njenge-FGD Nozzle impahla ukuqina kwayo okuhle nokumelana nokugqoka nokugqwala. Izitshalo zamandla zivame ukusebenza ngaphansi kwezimo ezinzima, ezinamazinga okushisa aphezulu nezinhlayiya ezingezinhle ezikhona kugesi we-flue. I-Silicon Carbide nozzles ingamelana nalezi zindawo eziyinselele, iqinisekise impilo yenkonzo ende futhi yanciphisa izindleko zokulungisa. Lokhu kuqina akugcini nje ngokuthuthukisa ukusebenza kahle kwenqubo yokususwa kwemali, kepha futhi kuyasiza ukuthuthukisa ukuthembeka okuphelele kwemisebenzi yezitshalo zamandla.
Ngokungeziwe ekususeni, i-FGD Sic nozzles nayo idlala indima ekusukeni nasekususweni kothuli. I-Flue igesi emaphethelweni ama-Poal-Power Plants aqukethe kuphela i-sulfur dioxide, kodwa futhi futhi ne-nitrogen oxides (nox) nezinkinga zokubandakanya. Ngokuhlanganisa amasistimu we-FGD ngobuchwepheshe be-Denitrification, izitshalo zamandla zingaphatha ukungcola okuningi ngasikhathi sinye, ngcono kakhulu ukuthuthukisa umoya. Amandla okubhekana nalokhu kuphuma okuhlukile kubalulekile ekuhlangabezaneni namazinga ezemvelo futhi anciphise ukukhiqizwa kwekhabhoni okuphelele kokukhiqizwa kwamandla.
Umthelela wezemvelo wokusebenzisa ama-FGD Silicon Carbide Nozzles afinyelela kude. Ngaphandle kokudideka okusebenzayo kanye nokudilizwa, ukuphuma kwegesi okuphambanisa kusuka ezitshalweni zamandla kungadala ukungcoliswa komoya okukhulu, okuholela ezifweni zokuphefumula kanye nokuwohloka kwemvelo. Ngaphezu kwalokho, ukuphuma okungafanele kusuka ezitshalweni zamapholaji amalahle kungalimaza izingxenye zokuphela ezishisayo zama-turbines wegesi kuzinhlelo ezihlanganisiwe zomjikelezo, okuholela ekuvuseleleni okubizayo kanye nokungasebenzi kahle. Ngokutshala imali kubuchwepheshe obuthuthukile we-FGD, izitshalo zamandla azikwazi ukuvikela imvelo kuphela, kodwa futhi zithuthukisa ukusebenza kwazo okusebenzayo kanye nokusebenza kwezomnotho.
Njengoba isimo sezwe lomhlaba jikelele sisaqhubeka nokuvela, isidingo sokuhlanza, imithombo yamandla esimeme ngokwengeziwe iyaphuthuma. I-FGD Silicon Carbide nozzles iyingxenye ebalulekile yokuguqulwa kokukhiqizwa kwamandla okuluhlaza. Ngokususa ngempumelelo ukungcola okuyingozi kumagesi we-flue, lawa ma-nozzles asiza izitshalo zamandla ahlangabezane nezidingo zokulawula futhi afake isandla kwiplanethi enempilo. Njengoba kuthuthukiswa ubuchwepheshe kanye nesidingo sobuphathi bezemvelo kuyaqhubeka ukukhula, indima ye-FGD Silicon Carbide nozzles ekulweni nokungcoliswa komoya nokuguquguquka kwesimo sezulu ngeke kubucayi ngokwengeziwe.
Ngamafuphi, i-FGD Silicon Carbide Nozzle iyinto ebalulekile emkhakheni we-Power Plant Defelfurization. Idizayini yayo eyingqayizivele, ukuqina, kanye nokusebenza kahle ekususeni i-sulphur dioxide nokunye ukungcoliswa kwabe kungukuthi kube yinto ebalulekile ekuphishekeleni ukukhiqizwa kwamandla okuhlanza. Njengoba izitshalo zamandla ziqhubeka nokwamukela ubuchwepheshe obuthuthukile ukuze banciphise umthelela wabo wezemvelo, ukubaluleka kwe-FGD Silicon Carbide Nozzles kuzokhulisa kuphela, kuveze indlela yekusasa elizinzile.
