Kutheni umxholo ophantsi wokungcola umisela ukusebenza kokwenyani kwesitena sokukhusela i-hot blast stove mullite?

Kwiisitovu ezishushu, izitena zokukhusela ubushushu zisebenza rhoqo1200–1400°C (2192–2552°F)ngelixa ujongene neegesi ezishushu ezinesantya esiphezulu, ukujikeleza kobushushu okuphindaphindiweyo, ukukhukuliseka kothuli, kunye nokunciphisa imozulu rhoqo ene-CO kunye ne-H₂. Le yindawo eqhelekileyo yoxinzelelo oludibeneyo kubushushu obuphezulu. Izitena zokukhusela zemveli ezinomthamo ophezulu wokungcola zihlala zifumana oku kulandelayo:

• Ukuthambisa kunye nokuguquguquka ngenxa yokwakheka kwesigaba esinjengeglasi kakhulu kumaqondo obushushu aphezulu

• Ukonakala kwe-Mullite okukhokelela kwisakhiwo esibuthathaka nesibuthathaka

• Ukungcola okusekwe kwisinyithi kuncipha kwaye kuba ngumgubo, okubangela ukulahleka kwamandla

Zonke ezi ndlela zokungaphumeleli zibonisa unobangela omnye oyintloko:ukungcola okugqithisileyo.

Izitena zokugquma ze-mullite ze-CCEWOOL® ziphucula uzinzo lwezitena oluhlala ixesha elide phantsi kweemeko ezinzima ngokulawula ngokungqongqo ubunyulu bezinto eziluhlaza kunye nokuzinzisa ulwakhiwo lwesigaba sekristale, zifikelela kumanqanaba okungcola angaphantsi kakhulu komyinge weshishini.

I-CCEWOOL® iluphucula njani uzinzo lwelinki yesitovu esishushu ngokunciphisa ukungcola?

Ulawulo Lobunyulu Bezinto Eziluhlaza: Inkqubo Yokungcola Okuphantsi Eyakha Isakhelo Esizinzileyo Sobushushu Obuphezulu

Isitena sokukhusela i-mullite se-CCEWOOL® sisebenzisa izinto eziluhlaza ezicocekileyo kakhulu ezivela kwiidiphozithi zayo zeeminerali kwaye sithintela ngokungqongqo ukungcola okuncibilikayo okufana nokuI-Fe₂O₃, i-K₂O, kunye ne-Na₂OUvavanyo lwangaphambi kokwenziwa oluzenzekelayo lususa amasuntswana esinyithi kunye nothuli lodongwe, luqinisekisa ukunyibilika okucocekileyo kunye nesigaba sekristale esizinzileyo emva kokubola.

Inkqubo yokungcola okuphantsi iphucula ngokuthe ngqo ukusebenza kobushushu obuphezulu:

• Ukwakheka kwesigaba esifana neglasi okunciphileyo– izitena zihlala ziqinile kwi-1200–1400°C ngaphandle kokuthamba okanye ukudilika kwangaphambi kwexesha

• Ukuthintelwa kweempendulo zekristale ezingafunekiyo– ulusu lwe-mullite lugcina ulusu luqhubeka kakuhle, kwaye iindonga zemingxuma azirhabaxa okanye azidibani

• Uzinzo lwemibhobho yexesha elide– iindonga zemingxunya ziyamelana nokushwabana okanye ukuqhekeka ngexesha lokujikeleza kobushushu, zigcina ukuhanjiswa kobushushu kuzinzile

Ngale ndlela yokunyibilikisa ecocekileyo kakhulu nengangcolanga kangako, izitena zokugquma ze-mullite ze-CCEWOOL® zibonisa ukuchasana okuphezulu kunye nozinzo lwesakhiwo kwiimeko ezinzima zokusebenza kwezitovu ezishushu.

Ukudubula ngokuchanekileyo: Ukunciphisa Iziphumo Zokungcola Ngokusebenzisa Ukucoca Okulawulwayo

Izitena ze-insulation ze-CCEWOOL® mullite ziyatshiswaI-oven yomhubhe ezenzekelayo ngokupheleleyo yemitha ezingama-88, nto leyo eqinisekisa ukuba intsimi yobushushu izinzile kwaye iyafana. Oku kuthintela ukutsha okanye ukutsha kakhulu kwaye kuvumela ukungcola okunyibilikayo kancinci ukuba kuphendule ngokupheleleyo okanye kuguquke ngexesha lenkqubo yokutsha kwe-1200–1350°C, nto leyo ebangela ukuba isakhiwo se-mullite esixineneyo nesizinzileyo.

Ngokusekelwe kule nkqubo yokungcola okuphantsi, izitena zokufakelwa i-mullite ze-CCEWOOL® zibonelela ngeenzuzo eziphambili zokusebenza:

• Iimbobo ezimbalwa kwaye akukho kuthamba okushisa okuphezulu, ukuqinisekisa uzinzo kwimilo

• I-mullite skeleton eqhubekayo ngakumbi, ukuphucula ukumelana noxinzelelo lobushushu

• Iindonga zemingxunya ezingashwabaniyo okanye ezingadilikiyo, ukugcina ubukhulu kunye nokuthembeka koomatshini

Ngenxa yoko, izitena zifikelela kwinqanaba eliphantsi lokushwabana komgca, amandla aphezulu okucinezelwa, kunye nozinzo oluphezulu lokutshayiswa kobushushu, okuthintela umgubo okanye ukuqhekeka ngexesha lenkonzo yexesha elide kwaye kubonelela ngesakhiwo se-lining esithembekileyo ngakumbi.

Ngomxholo wokungcola okuphantsi kakhulu, izitena ze-insulation ze-CCEWOOL® mullite zigcina uzinzo lwesakhiwo phantsi kobushushu obuphezulu, ukutshayiswa kobushushu, kunye nokunciphisa imozulu. Ziyamelana nokuthamba kunye nokugutywa ngelixa zigcina ukusebenza kobushushu ixesha elide. Yiyo loo ntoIzitena zokugquma ze-mullite ze-CCEWOOL®inika ukuthembeka okuphezulu kunye nobomi benkonzo obude kwii-hot blast stove applications.
