Ezimweni eziningi zokukhiqiza ezimbonini, izindawo ezinokushisa okuphezulu zivame kodwa ziyinselele kakhulu. Kungakhathaliseki ukuthi amalangabi avuthayo ngesikhathi sokuncibilikisa insimbi, izitofu ezinokushisa okuphezulu ekukhiqizeni ingilazi, noma ama-reactor anokushisa okuphezulu ekukhiqizeni amakhemikhali, izidingo eziqinile zibekwe ekumelaneni nokushisa okuphezulu kwezinto. Kukhona into edlala indima ebalulekile kulezi zinsimu ezinokushisa okuphezulu futhi engenakushaywa indiva, okuyiamabhlogo amelana nokushisa e-silicon carbide.
I-silicon carbide, ngokombono wokwakheka kwamakhemikhali, iyinhlanganisela eyakhiwe ngezinto ezimbili: i-silicon (Si) ne-carbon (C). Naphezu kokuba negama elithi 'silicon' egameni layo, ukubukeka kwayo kuhluke kakhulu ezintweni ze-silicon esizibona ekuphileni kwethu kwansuku zonke. I-silicon carbide ivame ukubonakala njengamakristalu amnyama noma aluhlaza, anobuthuntu obuqinile nobunzima obukhulu. Uma isetshenziswa ukuklwebha ingilazi, izoshiya kalula amamaki engilazini, njengokusika ibhotela ngommese omncane.
Isizathu sokuthi amabhlogo amelana nokushisa e-silicon carbide angavelela ezindaweni ezinokushisa okuphezulu kungenxa yochungechunge lwezakhiwo zawo ezinhle kakhulu. Okokuqala, inokumelana nokushisa okuphezulu kakhulu, enezinga lokuncibilika eliphakeme kakhulu, okusho ukuthi ingahlala izinzile ezindaweni ezijwayelekile zezimboni ezinokushisa okuphezulu futhi ngeke ithambise kalula, iguquguquke, noma incibilike. Lapho izinga lokushisa ngaphakathi kwesithando sokuncibilikisa insimbi likhuphuka kakhulu, ezinye izinto kungenzeka ukuthi seziqalile "ukuthwala umthwalo", kodwa amabhlogo amelana nokushisa e-silicon carbide "angahlala athule" futhi athwale umthwalo wokuvikela umzimba wesithando nokugcina umkhiqizo.
Ukuqina kwamakhemikhali kwamabhulokhi amelana nokushisa e-silicon carbide nakho kuhle kakhulu. Inokumelana okuhle nezinhlobo ezahlukene zamakhemikhali, futhi kunzima ngama-asidi aqinile aqothulayo noma izinto ze-alkaline ukuthi zibangele umonakalo kuyo. Ekukhiqizweni kwamakhemikhali, kuvame ukuhlangana namakhemikhali ahlukahlukene aqothulayo. Ukusebenzisa amabhulokhi amelana nokushisa e-silicon carbide njengolwelwesi lwemishini yokusabela kungavimbela ngempumelelo imishini ukuthi iqothule, kwandise isikhathi senkonzo yemishini, futhi kunciphise izindleko zokukhiqiza.
Ngaphezu kwezakhiwo ezingenhla, amabhlogo amelana nokushisa e-silicon carbide nawo anokumelana okuhle nokuguguleka kanye namandla aphezulu. Kwezinye izindawo ezishisa kakhulu ezinokuguguleka kwezinto, njengezihlukanisi zesiphepho kanye nezitofu ze-calcination ezitshalweni zesamente, amabhlogo amelana nokushisa e-silicon carbide anganciphisa ukulahlekelwa okubangelwa ukungqubuzana kwezinto ngenxa yezakhiwo zawo ezimelana nokuguga, okuqinisekisa ukusebenza okuvamile kwemishini. Amandla ayo aphezulu ayenza ikwazi ukumelana namandla athile okucindezela kanye nomthelela, igcine ubuqotho besakhiwo ezindaweni eziyinkimbinkimbi zezimboni.
Amabhulokhi amelana nokushisa e-silicon carbide asetshenziswa kabanzi emkhakheni wezimboni. Embonini yensimbi, isetshenziswa kabanzi emishinini efana nezitofu zokuqhuma kanye nezitofu zokuqhuma ezishisayo. Ngaphakathi kwesithando sokuqhuma, insimbi ecibilikisiwe eshisa kakhulu kanye ne-slag kunezidingo eziphakeme kakhulu zezinto zokubopha. Amabhulokhi amelana nokushisa e-silicon carbide, anokumelana nokushisa okuphezulu kanye nokumelana nokuguguleka, abe yisinqumo esifanele sezinto zokubopha, andisa ngempumelelo impilo yesevisi yesithando sokuqhuma futhi athuthukise ukusebenza kahle kanye nekhwalithi yokukhiqizwa kwensimbi. Esithandweni sokuqhuma esishisayo, amabhulokhi amelana nokushisa e-silicon carbide asebenza njengezindawo zokugcina ukushisa, ezingagcina futhi zikhulule ukushisa ngempumelelo, zinikeze umoya oshisayo oshisa kakhulu wesithando sokuqhuma futhi zithuthukise ukusebenza kahle kokusetshenziswa kwamandla.
Embonini yokuncibilikisa insimbi engenalo i-ferrous, njengenqubo yokuncibilikisa i-aluminium, ithusi nezinye izinsimbi, amabhlogo amelana nokushisa e-silicon carbide nawo abalulekile. Izinga lokushisa lokuncibilikisa lalezi zinsimbi liphezulu kakhulu, futhi amagesi ahlukahlukene agqwalisayo kanye ne-slag kukhiqizwa ngesikhathi senqubo yokuncibilikisa. Amabhlogo amelana nokushisa e-silicon carbide angazivumelanisa kahle nezimo ezinzima kangaka, avikele imishini yesithando somlilo, futhi aqinisekise ukuncibilikisa okubushelelezi kwezinsimbi ezingenalo i-ferrous.
Amabhulokhi amelana nokushisa e-silicon carbide nawo anezicelo ezibalulekile embonini ye-ceramic nengilazi. Ukushisa nge-ceramic kudinga ukwenziwa kuma-oven ashisa kakhulu. Ama-oven enziwe ngamabhulokhi e-silicon carbide amelana nokushisa, njengamabhodi eshede, amabhokisi, njll., awakwazi nje kuphela ukumelana nokushisa okuphezulu, kodwa futhi aqinisekisa ukuqina kanye nokufana kwemikhiqizo ye-ceramic ngesikhathi senqubo yokushisa, okusiza ukuthuthukisa ikhwalithi yemikhiqizo ye-ceramic. Ema-oven ancibilikisa ingilazi, amabhulokhi amelana nokushisa e-silicon carbide asetshenziselwa amakamelo okugcina ulwelwesi kanye nokushisa, angamelana nokuguguleka nokushisa okuphezulu kanye nokukhuhla uketshezi lwengilazi, ngenkathi kuthuthukiswa ukusebenza kahle kokushisa kwesithando somlilo kanye nokunciphisa ukusetshenziswa kwamandla.
Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nentuthuko eqhubekayo yemboni, amathuba okusetshenziswa kwamabhulokhi amelana nokushisa e-silicon carbide azoba maningi nakakhulu. Ngakolunye uhlangothi, abacwaningi bahlala behlola izinqubo ezintsha zokulungiselela kanye nobuchwepheshe ukuze bathuthukise ukusebenza kwamabhulokhi amelana nokushisa e-silicon carbide futhi banciphise izindleko zokukhiqiza. Isibonelo, ngokwamukela inqubo entsha yokusila, ubuningi kanye nesakhiwo samabhulokhi amelana nokushisa e-silicon carbide kungandiswa, ngaleyo ndlela kuthuthukiswe ukusebenza kwawo jikelele. Ngakolunye uhlangothi, ngokukhula okusheshayo kwezimboni ezisafufusa njengamandla amasha kanye nezindiza, isidingo sezinto ezimelana nokushisa okuphezulu naso siyakhula, futhi amabhulokhi amelana nokushisa e-silicon carbide kulindeleke ukuthi adlale indima enkulu kulezi zinsimu.
