Emzamweni wokukhiqiza amandla ahlanzekile, izimboni zikagesi ziya ngokuya zisebenzisa ubuchwepheshe obuthuthukisiwe ukunciphisa umthelela wazo kwezemvelo. Obunye balobu buchwepheshe buwukusetshenziswa kwezinhlelo ze-flue gas desulfurization (FGD), ezidlala indima ebalulekile ekwehliseni ukukhishwa kwe-sulfur dioxide. Enhliziyweni yalezi zinhlelo kukhona imibhobho ye-FGD silicon carbide, enziwe ngezinto zobumba ezibukhali ezibizwa nge-silicon carbide. Le bhulogi izohlola ukubaluleka kwalawa mibhobho, izinguquko zokuklama kwawo, kanye nomthelela wawo ekusimameni kwemvelo.
Imibhobho ye-silicon carbide yakhelwe ukwenza lula inqubo ye-desulfurization ezitshalweni zamandla. Umsebenzi wabo oyinhloko ukukhipha i-sulphur dioxide (SO2) nezinye izinto ezingcolile eziphuma emagesini aphuma ngesikhathi kushiswa izinto ezibaswayo, ikakhulukazi amalahle. Ukubaluleka kwale nqubo akukwazi ukweqiwa, njengoba i-sulphur dioxide inomthelela omkhulu emvuleni ene-asidi nokungcoliswa komoya, okungaba nemiphumela elimazayo empilweni yomuntu nasendaweni ezungezile. Ngokusebenzisa imibhobho ye-FGD silicon carbide, izitshalo zikagesi zinganciphisa kakhulu ukungcola futhi zihambisane nemithetho eqinile yezemvelo.
Imiklamo ye-FGD silicon carbide nozzles yakhelwe ukuthuthukisa ukusebenza kwayo ezinhlelweni zokusebenza ezahlukahlukene. Izinhlobo ezimbili zomlomo ezijwayelekile ezisetshenziswa ezinhlelweni ze-desulfurization i-spiral full cone nozzle kanye ne-vortex hollow cone nozzle. I-spiral full cone nozzle iklanyelwe ukukhiqiza inkungu enhle yoketshezi olumuncayo, okuthuthukisa ukuxhumana phakathi koketshezi kanye negesi yomoya, ngaleyo ndlela kwandise ukusebenza kahle kwenqubo ye-desulfurization. I-vortex hollow cone nozzle, ngakolunye uhlangothi, ikhiqiza iphethini yesifutho ejikelezayo esabalalisa kangcono okumuncayo, okuqinisekisa ukwelashwa okuphelele kwegesi yomkhuhlane. Ukukhethwa kwalezi zinhlobo ze-nozzle kuncike ezidingweni ezithile zesikhungo samandla kanye nezici zegesi eshaywayo ephathwayo.
Enye yezinzuzo eziyinhloko ze-silicon carbide njenge-FGD nozzle material ukuqina kwayo okuhle kakhulu nokumelana nokugqoka nokugqwala. Izitshalo zamandla zivame ukusebenza ngaphansi kwezimo ezinzima, ezinamazinga okushisa aphezulu kanye nezinhlayiya ezilumayo ezikhona ku-flue gas. Imibhobho ye-silicon carbide ingamelana nalezi zindawo eziyinselele, iqinisekise impilo ende yesevisi kanye nezindleko zokulungisa ezincishisiwe. Lokhu kuqina akuthuthukisi nje kuphela ukusebenza kahle kwenqubo ye-desulfurization, kodwa futhi kusiza ukuthuthukisa ukwethembeka okuphelele kokusebenza kwezitshalo zamandla.
Ngokungeziwe ekwehliseni i-sulfurization, imibhobho ye-FGD SiC nayo idlala indima ekukhishweni kwe-denitrification nasekususeni uthuli. I-flue gas evela ezitshalweni zamandla aqhutshwa ngamalahle ayiqukethe kuphela i-sulphur dioxide, kodwa futhi nama-nitrogen oxides (NOx) kanye ne-particle matter. Ngokuhlanganisa amasistimu e-FGD nobuchwepheshe be-denitrification, izitshalo zamandla zingakwazi ukwelapha ukungcola okuningi ngesikhathi esisodwa, zithuthukise ikhwalithi yomoya. Ikhono lokubhekana nalokhu kukhishwa okuhlukene kubalulekile ukuze kuhlangatshezwane namazinga emvelo kanye nokunciphisa i-carbon footprint yokukhiqiza amandla.
Umthelela wemvelo wokusebenzisa i-FGD silicon carbide nozzles ufinyelela kude. Ngaphandle kwe-desulfurization ephumelelayo kanye ne-denitrification, ukukhishwa kwegesi ye-flue evela ezitshalweni zamandla kungabangela ukungcoliswa komoya okukhulu, okuholela ezifweni zokuphefumula kanye nokucekelwa phansi kwemvelo. Ukwengeza, ukukhishwa okungahlungiwe okuvela ezimbonini zamandla asetshenziswa ngamalahle kungalimaza izingxenye ezishisayo zamaturbine egesi ezinhlelweni zomjikelezo ohlangene, okuholela ekulungiseni okubizayo kanye nokungasebenzi kahle. Ngokutshala imali kubuchwepheshe obuthuthukisiwe be-FGD, izitshalo zamandla azikwazi nje ukuvikela imvelo, kodwa futhi zithuthukise ukusebenza kwazo nokusebenza kwezomnotho.
Njengoba isimo samandla omhlaba siqhubeka nokuguquguquka, isidingo semithombo yamandla ehlanzekile, esimeme kakhulu siya ngokuphuthuma kakhulu. I-FGD silicon carbide nozzles iyingxenye ebalulekile yokushintshela ekukhiqizeni amandla aluhlaza. Ngokususa ngempumelelo ukungcola okuyingozi kumagesi aphuma ku-flue, le mibhobho isiza izikhungo zikagesi ukuthi zihlangabezane nezimfuneko zokulawula futhi zibe negalelo kuplanethi enempilo. Njengoba ubuchwepheshe buthuthuka kanye nesidingo sokunakekelwa kwemvelo siqhubeka sikhula, indima ye-FGD silicon carbide nozzles ekulweni nokungcoliswa komoya kanye nokushintsha kwesimo sezulu ngokungangabazeki kuzoba bucayi kakhulu.
Kafushane, i-FGD Silicon Carbide Nozzle iwukuqanjwa okusha okubalulekile emkhakheni we-desulfurization yezitshalo zamandla. Idizayini yayo eyingqayizivele, ukuqina, kanye nempumelelo ekususeni i-sulphur dioxide nokunye ukungcola kuyenza ibe isici esibalulekile ekuphishekeleni ukukhiqizwa kwamandla ahlanzekile. Njengoba izimboni zikagesi ziqhubeka nokusebenzisa ubuchwepheshe obuthuthukile bokunciphisa umthelela wazo kwezemvelo, ukubaluleka kwe-FGD Silicon Carbide Nozzles kuzokhula kuphela, kuvule indlela yekusasa elizinzile.
