Ekufuneni ukukhiqizwa kwamandla ahlanzekile, izitshalo zamandla ziya ngokuya zisebenzisa ubuchwepheshe obuthuthukisiwe ukunciphisa umthelela wazo emvelweni. Enye yalezi zobuchwepheshe ukusetshenziswa kwezinhlelo ze-flue gas desulfurization (FGD), ezidlala indima ebalulekile ekunciphiseni ukukhishwa kwe-sulfur dioxide. Enhliziyweni yalezi zinhlelo kukhona ama-nozzle e-silicon carbide e-FGD, enziwe ngezinto ze-ceramic ezisezingeni eliphezulu ezibizwa ngokuthi i-silicon carbide. Le bhulogi izohlola ukubaluleka kwala ma-nozzle, izinguquko zomklamo wawo, kanye nomthelela wawo ekusimeni kwemvelo.
Ama-nozzle e-silicon carbide aklanyelwe ukwenza lula inqubo yokususa i-sulfurization ezitshalweni zikagesi. Umsebenzi wawo oyinhloko ukususa i-sulfur dioxide (SO2) kanye nezinye izinto ezingcolisayo eziyingozi ezivela kumagesi aphumayo akhishwa ngesikhathi sokushiswa kwamafutha emvelo, ikakhulukazi amalahle. Ukubaluleka kwale nqubo akunakuphikiswa, njengoba i-sulfur dioxide inegalelo elikhulu ekungcolisweni kwemvula ene-asidi nomoya, okungaba nemiphumela emibi empilweni yabantu kanye nemvelo. Ngokusebenzisa ama-nozzle e-silicon carbide e-FGD, izitshalo zikagesi zinganciphisa kakhulu ukukhishwa kwegesi futhi zihambisane nemithetho eqinile yezemvelo.
Imiklamo yama-nozzles e-silicon carbide e-FGD yenzelwe ukwenza ngcono ukusebenza kwawo ezinhlotsheni ezahlukahlukene zokusebenza. Izinhlobo ezimbili ezivamile zama-nozzles ezisetshenziswa ezinhlelweni zokususa i-sulfurization yi-spiral full cone nozzle kanye ne-vortex hollow cone nozzle. I-spiral full cone nozzle yenzelwe ukukhiqiza inkungu encane yoketshezi olumuncayo, okuthuthukisa ukuxhumana phakathi koketshezi negesi yokukhipha i-flue, ngaleyo ndlela kwandiswe ukusebenza kahle kwenqubo yokususa i-sulfurization. I-vortex hollow cone nozzle, ngakolunye uhlangothi, ikhiqiza iphethini yokufutha ejikelezayo esabalalisa kangcono i-absorbent, iqinisekisa ukwelashwa okuphelele kwegesi yokukhipha i-flue. Ukukhetha kwalezi zinhlobo zama-nozzle kuncike ezidingweni ezithile zesitshalo samandla kanye nezici zegesi yokukhipha i-flue ephathwayo.
Enye yezinzuzo eziyinhloko ze-silicon carbide njenge-nozzle ye-FGD ukuqina kwayo okuhle kakhulu kanye nokumelana nokuguguleka nokugqwala. Izitshalo zikagesi zivame ukusebenza ngaphansi kwezimo ezinzima, lapho amazinga okushisa aphezulu kanye nezinhlayiya ezihuquzelayo zikhona kugesi yomoya. Izibhamu ze-silicon carbide zingamelana nalezi zimo eziyinselele, ziqinisekise impilo yesevisi ende kanye nezindleko zokulungisa ezincishisiwe. Lokhu kuqina akugcini nje ngokuthuthukisa ukusebenza kahle kwenqubo yokususa i-sulfurization, kodwa futhi kusiza ukuthuthukisa ukuthembeka okuphelele kokusebenza kwezitshalo zikagesi.
Ngaphezu kokususa i-sulfurization, ama-nozzle e-FGD SiC nawo adlala indima ekususeni i-nitrification kanye nokususwa kothuli. Igesi yomoya evela ezitshalweni zamandla ezisebenzisa amalahle ayinayo i-sulfur dioxide kuphela, kodwa futhi nama-nitrogen oxides (NOx) kanye nezinto ezincane. Ngokuhlanganisa izinhlelo ze-FGD nobuchwepheshe bokususa i-nitrification, izitshalo zamandla zingaphatha ukungcola okuningi ngesikhathi esisodwa, okuqhubeka nokuthuthukisa ikhwalithi yomoya. Ikhono lokubhekana nalokhu kukhishwa okuhlukile libalulekile ekuhlangabezaneni nezindinganiso zemvelo kanye nokunciphisa umthelela wekhabhoni ophelele wokukhiqizwa kwamandla.
Umthelela wezemvelo wokusebenzisa ama-nozzle e-silicon carbide e-FGD ubanzi kakhulu. Ngaphandle kokukhipha i-sulfurization kanye ne-denitrification ephumelelayo, ukukhishwa kwegesi yomoya ovela ezitshalweni zamandla kungabangela ukungcola komoya okukhulu, okuholela ezifweni zokuphefumula kanye nokuwohloka kwemvelo. Ngaphezu kwalokho, ukukhishwa kwegesi okungahlungiwe okuvela ezitshalweni zamandla ezisebenzisa amalahle kungalimaza izingxenye ezishisayo zama-turbine egesi ezinhlelweni zomjikelezo ezihlanganisiwe, okuholela ekulungisweni okubizayo kanye nokungasebenzi kahle kokusebenza. Ngokutshala imali kubuchwepheshe obuthuthukisiwe be-FGD, izitshalo zamandla azigcini nje ngokuvikela imvelo, kodwa futhi zithuthukise ukusebenza kwazo kanye nokuphila kahle kwezomnotho.
Njengoba isimo samandla omhlaba wonke siqhubeka nokuguquka, isidingo semithombo yamandla ehlanzekile nehlala isikhathi eside siya ngokuya siphuthuma. Ama-nozzle e-silicon carbide e-FGD ayingxenye ebalulekile yokushintshela ekukhiqizweni kwamandla aluhlaza. Ngokususa ngempumelelo ukungcola okuyingozi kumagesi angcolile, la ma-nozzle asiza izitshalo zamandla ukuhlangabezana nezidingo zomthetho futhi anikele eplanethini enempilo. Njengoba ubuchwepheshe buthuthuka kanye nesidingo sokuphathwa kwemvelo siqhubeka nokukhula, indima yama-nozzle e-silicon carbide e-FGD ekulweni nokungcoliswa komoya kanye nokushintsha kwesimo sezulu ngokungangabazeki izoba yinto ebaluleke kakhulu.
Ngamafuphi, i-FGD Silicon Carbide Nozzle iyithuluzi elibalulekile emkhakheni wokususa i-sulfurization yezitshalo zamandla. Umklamo wayo oyingqayizivele, ukuqina kwayo, kanye nokusebenza kahle ekususeni i-sulfur dioxide nezinye izinto ezingcolisayo kwenza kube yinto ebalulekile ekuphishekeleni ukukhiqizwa kwamandla ahlanzekile. Njengoba izitshalo zamandla ziqhubeka nokusebenzisa ubuchwepheshe obuthuthukisiwe ukunciphisa umthelela wazo emvelweni, ukubaluleka kwama-FGD Silicon Carbide Nozzles kuzokhula kuphela, kuvuleke indlela yekusasa elizinzile.
