Ukuqonda amalahle okuCoka: Isikhokelo esiBanzi

Esi sikhokelo sinika amagqabantshintshi abanzi ukupheka amalahle, ukuhlola iipropati zayo, ukusetyenziswa, amandla emarike, kunye nefuthe lokusingqongileyo. Siye sijonge kwiindidi ezahlukeneyo ze ukupheka amalahle, inkqubo yayo yokuvelisa, nendima yayo ebalulekileyo kumashishini awahlukeneyo. Funda ngehlabathi jikelele ukupheka amalahle market, kubandakanywa abadlali eziphambili kunye neendlela elizayo. Olu lwazi luyimfuneko kuye nabani na obandakanyekayo kwishishini lensimbi okanye onomdla wokuqonda lo mthombo obalulekileyo.

Yintoni i-Coking Coal?

Ukupheka amalahle, ekwaziwa ngokuba yi-metallurgical coal, luhlobo oluthile lwamalahle olunombandela ophantsi oguquguqukayo kunye nomxholo ophezulu wekhabhoni. Ngokungafaniyo nezinye iintlobo zamalahle asetyenziselwa ukwenza umbane, ukupheka amalahleiipropati ezizodwa ziyenza ilungele ukusetyenziswa kwiziko lokuqhushumba ukuvelisa intsimbi kunye nentsimbi. Ukukwazi ukumelana namaqondo obushushu aphezulu ngaphandle kokuqhekeka kubalulekile kwinkqubo yokupheka, ebandakanya ukufudumeza amalahle ukukhupha izinto eziguquguqukayo kunye nokudala i-coke eyomeleleyo, ene-porous.

Iintlobo zamalahle okuPheka

Ukupheka amalahle ihlelwe ngokusekelwe kwizinto ezininzi, kubandakanywa umgangatho wayo (inqanaba le-metamorphism), umxholo wezinto eziguquguqukayo, kunye neempawu zokupheka. Ngokuqhelekileyo, i-high-volatile ukupheka amalahle, ukuguquguquka okuphakathi ukupheka amalahle, kunye ne-low-volatile ukupheka amalahle zahlula, nganye ineempawu zayo ezizodwa kunye nokusetyenziswa kwi-steelmaking. Umdibaniso weentlobo ezahlukeneyo ze ukupheka amalahle idla ngokulungiswa ukufezekisa umgangatho we-coke ofunekayo kwiinkqubo ezithile zokuvelisa intsimbi.

Inkqubo Yokupheka

Inkqubo yokupheka yinyathelo elibalulekileyo kwimveliso yentsimbi. Ibandakanya ukufudumeza ukupheka amalahle ngokungabikho komoya (pyrolysis) kwii-ovens ze-coke kumaqondo aphezulu (malunga ne-900-1000 ° C) iiyure eziliqela. Le nkqubo iguqula ilahle ibe yi-coke, i-carbon material ene-porous enamandla kunye nokusebenza kwakhona, okuyimfuneko ekunciphiseni i-iron ore kwisithando somlilo. Iimveliso zenkqubo yokupheka, njengegesi ye-oveni ye-coke kunye netha yamalahle, nazo zizixhobo ezixabisekileyo kunye nokusetyenziswa kwemizi-mveliso eyahlukeneyo.

IMarike yamalahle eCoking yeHlabathi

Ihlabathi jikelele ukupheka amalahle imakethi iphenjelelwa kakhulu yimiba efana namanqanaba emveliso yentsimbi, ukukhula koqoqosho lwehlabathi, kunye nemimiselo yokusingqongileyo. Abavelisi abakhulu kunye nabathengi be ukupheka amalahle zigxile ngokwejografi, nto leyo ekhokelela kutshintsho oluntsonkothileyo lwekhonkco lonikezelo. Ixabiso le ukupheka amalahle iyaguquguquka kwaye ihlala ibonakalisa ibhalansi phakathi konikezelo kunye nemfuno kwimarike yehlabathi. Ukuqonda olu tshintsho lwemarike kubalulekile kumashishini abandakanyekayo kwi ukupheka amalahle ishishini.

Ukuqwalaselwa kokusingqongileyo

Ukukhutshwa kunye nokusetyenziswa kwe ukupheka amalahle zineziphumo ezibalulekileyo zokusingqongileyo. Imisebenzi yemigodi inokukhokelela ekuthotyweni komhlaba, ungcoliseko lwamanzi, kunye nokukhutshwa kwegesi yegreenhouse. Inkqubo yokupheka ngokwayo ivelisa izinto ezikhutshwayo, kubandakanywa izinto ezingcolisayo ezifana ne-sulfur oxides kunye ne-particulate matter. Ushishino lwentsimbi lugxininisa ngakumbi ekunciphiseni impembelelo yokusingqongileyo ukupheka amalahle ukusetyenziswa ngokusungula izinto ezintsha zobuchwepheshe kunye nezenzo ezizinzileyo.

IiNdlela zekamva kuShishino lwamalahle okuCoking

Ikamva le ukupheka amalahle ishishini ibunjwe zizinto eziliqela, kuquka ukuqhubela phambili kwezobuchwepheshe, imimiselo yokusingqongileyo, kunye nemfuno ekhulayo yentsimbi. Uphando luyaqhuba ukuphuhlisa iindlela ezicocekileyo nezisebenzayo ze ukupheka amalahle imveliso kunye nokusetyenziswa. Ukwamkelwa kobunye ubuchwephesha, obufana nokusetyenziswa kwe-biomass okanye imathiriyeli ephinda isetyenziswe ekwenzeni intsimbi, nako kunokuba nefuthe elimandla kwimfuno yexesha elizayo ukupheka amalahle.

Abadlali abaphambili kuShishino lwamalahle okuCoking

Iinkampani ezininzi ezinkulu zamazwe ngamazwe zidlala indima ebalulekileyo kwihlabathi ukupheka amalahle imarike. Ezi nkampani zibandakanyeka kwimiba eyahlukeneyo yeshishini, ukusuka kwimigodi kunye nokulungiswa ukuya kurhwebo kunye nokusasazwa. Ukuqonda abathathi-nxaxheba abaphambili kunye nezicwangciso zabo zentengiso kunika ulwazi malunga nokutshintsha kweshishini kunye nentsingiselo yexesha elizayo. Umzekelo, i-Inner Mongolia Xinxin Silicon Industry Co.,Ltd (https://www.xinxinsilicon.com/) ngumdlali obalulekileyo kumzi mveliso wesilicon, eqaqambisa ukudityaniswa kwezixhobo ezahlukeneyo ngaphakathi kwendawo yoshishino ebanzi.
