Ikhebula Elifakwe Ukushisa Kwamaminerali (ikhebula le-MICC noma le-MI), njengohlobo olukhethekile lwekhebula, lisetshenziswa kabanzi kuzo zonke izindlela zokuphila ngenxa yokumelana kwalo okuhle kakhulu nomlilo, ukumelana nokugqwala kanye nokuqina kokudlulisela. Leli phepha lizokwethula isakhiwo, izici, amasimu okusetshenziswa, isimo semakethe kanye nethuba lokuthuthukiswa kwekhebula elifakwe ukufudumala kwamaminerali ngokuningiliziwe.
1. Isakhiwo nezici
Ikhebula elifakwe umswakama wamaminerali lakhiwe kakhulu ngocingo oluyinhloko lomqhubi wethusi, ungqimba lokuvikela umswakama we-magnesium oxide kanye nomgodi wethusi (noma umgodi we-aluminium). Phakathi kwazo, ucingo oluyinhloko lomqhubi wethusi lusetshenziswa njengendawo yokudlulisela ugesi, kanti umgubo we-magnesium oxide usetshenziswa njengento yokuvikela engaphili ukuze kuhlukaniswe umqhubi kanye nomgodi ukuqinisekisa ukusebenza kukagesi kanye nokuphepha kwekhebula. Ungqimba olungaphandle lungakhethwa ngokuya ngezidingo zesivikelo esifanele, ukuze kuthuthukiswe ukuvikelwa kwekhebula.
Izici zekhebula elifakwe amaminerali zibonakala kakhulu kulezi zici ezilandelayo:
(1) Ukumelana nomlilo okuphezulu: Ngenxa yokuthi ungqimba lokuvikela lwenziwe ngezinto zamaminerali ezingaphili njenge-magnesium oxide, izintambo ezivikela amaminerali zisengagcina ukusebenza kahle kokuvikela emazingeni okushisa aphezulu futhi zivimbele umlilo ngempumelelo. Igobolondo layo lethusi lizoncibilika ku-1083 ° C, kanti ukuvikela amaminerali kungamelana namazinga okushisa aphezulu angaphezu kuka-1000 ° C.
(2) Ukumelana nokugqwala okuphezulu: ithubhu yethusi elingenamthungo noma ithubhu le-aluminium njengento yokubeka emgodleni, ukuze ikhebula elifakwe amaminerali likwazi ukumelana nokugqwala okuphezulu, lingasetshenziswa ezindaweni ezinzima isikhathi eside.
(3) Ukuqina kokudlulisa okuphezulu: Ikhebula elifakwe ugesi lamaminerali lisebenza kahle kakhulu ekudluliseni, lifanelekela ibanga elide, ukudluliswa kwedatha ngesivinini esikhulu kanye nokudluliswa kwamandla kagesi aphezulu kanye nezinye izimo. Linomthamo omkhulu wokuthwala ugesi, isilinganiso esiphezulu samaphutha e-short-circuit, futhi lingadlulisa ugesi ophezulu ngokushisa okufanayo.
(4) Impilo yesevisi ende: ngenxa yokumelana kwayo nomlilo, ukumelana nokugqwala nezinye izici, impilo yesevisi yezintambo ezifakwe ugesi zamaminerali yinde kakhulu, ngokuvamile ifinyelela eminyakeni engaba ngu-70.
2. Inkambu yezicelo
Izintambo ezifakwe umswakama wamaminerali zisetshenziswa kabanzi kuzo zonke izindlela zokuphila, ikakhulukazi okuhlanganisa:
(1) Izakhiwo eziphakeme: ezisetshenziselwa ukukhanyisa okuvamile, ukukhanyisa okuphuthumayo, i-alamu yomlilo, izintambo zikagesi zomlilo, njll., ukuqinisekisa ukuthi ugesi ojwayelekile usakwazi ukunikezwa ezimweni eziphuthumayo.
(2) Imboni yamakhemikhali kaphethroli: Ezindaweni ezingaba yingozi zokuqhuma, ukumelana nomlilo okuphezulu kanye nokumelana nokugqwala kwezintambo ezivikelwe ngamaminerali kuzenza zibe zinhle kakhulu.
(3) Ezokuthutha: izikhumulo zezindiza, imigudu yesitimela esingaphansi komhlaba, imikhumbi nezinye izindawo, izintambo ezivikelwe ngamaminerali zisetshenziselwa ukukhanyisa okuphuthumayo, izinhlelo zokuqapha umlilo, imigqa yokungenisa umoya, njll., ukuqinisekisa ukusebenza okuphephile kwezindawo zomgwaqo.
(4) Izikhungo ezibalulekile: njengezibhedlela, izikhungo zedatha, amakamelo okulawula umlilo, njll., zinezidingo eziphezulu zokuzinza kokudluliselwa kwamandla nokusebenza komlilo, kanti izintambo ezifakwe amaminerali avikelwe zibalulekile.
(5) Indawo ekhethekile: umhubhe, isisekelo kanye nezinye izindawo ezivaliwe, ezinomswakama, ezinokushisa okuphezulu, ukumelana nomlilo wekhebula, izidingo zokumelana nokugqwala ziphakeme, ikhebula elifakwe amaminerali lingahlangabezana nalezi zidingo.
3. Isimo semakethe kanye namathuba entuthuko
Njengoba kugxilwe kakhulu ekuphepheni komlilo, isidingo semakethe sezintambo ezivikelwe ngamaminerali siyakhula. Ikakhulukazi kumaphrojekthi wamandla avuselelekayo njengelanga nomoya, izintambo ezivikelwe ngamaminerali zisetshenziswa kabanzi ngenxa yezakhiwo zazo ezingashisi umlilo. Kubikezelwa ukuthi ngo-2029, usayizi wemakethe yezintambo ezivikelwe ngamaminerali emhlabeni wonke uzofinyelela ku-$2.87 billion, ngesilinganiso sokukhula sonyaka esihlanganisiwe (CAGR) esingu-4.9%.
Emakethe yasekhaya, ngokusebenzisa amazinga afana ne-GB/T50016, ukusetshenziswa kwezintambo ezifakwe amaminerali ezicijile emigqeni yomlilo kube yimpoqo, okuye kwakhuthaza intuthuko yemakethe. Njengamanje, izintambo zikagesi ezifakwe amaminerali ezicijile zithatha isabelo semakethe esiyinhloko, kanti izintambo zokushisa ezifakwe amaminerali nazo zandisa kancane kancane ububanzi bazo bokusetshenziswa.
4. Isiphetho
Ikhebula elifakwe amaminerali lidlala indima ebalulekile kuzo zonke izigaba zokuphila ngenxa yokumelana kwalo okuhle kakhulu nomlilo, ukumelana nokugqwala kanye nokuqina kokudlulisela. Ngokuthuthuka okuqhubekayo kwezidingo zokuphepha komlilo kanye nokuthuthukiswa okusheshayo kwamaphrojekthi wamandla avuselelekayo, amathuba emakethe ezintambo ezifakwe amaminerali afakwe amaminerali abanzi. Kodwa-ke, izindleko zayo eziphakeme kanye nezidingo zokufakwa nazo kudingeka zicatshangelwe ekukhetheni nasekusetshenzisweni. Ekuthuthukisweni kwesikhathi esizayo, izintambo ezifakwe amaminerali afakwe amaminerali zizoqhubeka nokudlala izinzuzo zazo ezihlukile zokudlulisela amandla kanye nokuphepha komlilo kuzo zonke izigaba zokuphila.
