Qhov sib txawv tseem ceeb ntawm coking thee thiab thermal thee yog cov coking thee feem ntau yog siv los tsim cov coke zoo, qhov thermal coke tseem ceeb hauv kev tsim hluav taws xob.
Coal yog ib hom pob zeb sedimentary uas yog combustible. Nws tshwm nyob rau hauv dub los yog brownish-dub xim. Feem ntau, thee muaj cov pa roj carbon thiab cov nqi sib txawv ntawm lwm cov tshuaj xws li hydrogen, sulfur, oxygen, thiab nitrogen. Muaj ntau hom thee, xws li peat, lignite, sub-bituminous thee, bituminous thee, thiab lwm yam nyob ntawm seb muaj pes tsawg leeg. Tsis tas li, peb tuaj yeem categorize thee rau hauv ntau hom raws li daim ntawv thov; thermal thee thiab coking thee yog ob yam zoo li no.
Coking Coal yog dab tsi?
Coking thee yog hom thee uas tseem ceeb hauv kev ua cov coke zoo. Nws tseem hu ua metallurgical thee. Cov khoom no yog ib qho tseem ceeb roj thiab yog ib qho tseem ceeb raws li ib tug reactant nyob rau hauv lub blast furnace txheej txheem ntawm thawj steelmaking. Yog li ntawd, qhov kev thov rau hom thee no yog sib npaug rau cov hlau. Vim tib lub laj thawj, cov tuam txhab tsim steel muaj kev faib ua cov coking thee txhawm rau kom tau txais tus nqi qis rau lawv cov txheej txheem tsim cov hlau.
Daim duab 01: Coke
Coking thee muaj cov hmoov tshauv tsawg, cov ntsiab lus tsis tshua muaj dej thiab tsis muaj leej faj thiab phosphorous cov ntsiab lus. Peb tuaj yeem categorize coking thee ua ib hom bituminous thee nyob ntawm cov tshuaj muaj pes tsawg leeg. Hom thee no tuaj yeem tsim cov coke muaj zog thiab qis qis thaum nws yog rhuab nyob rau hauv lub xub ntiag ntawm cov pa oxygen. Thaum cov txheej txheem cua sov no, coking thee softens. Cov Cheebtsam volatile zoo li evaporate, thiab cov khoom no ces khiav tawm los ntawm qhov hws hauv cov thee loj.
Thaum lub sijhawm txheej txheem coking (kev tsim cov coke los ntawm coking thee), cov khoom nyhav o thiab nws cov ntim nce. Lub peev xwm ntawm coking thee los tsim coke cuam tshuam rau nws lub cev muaj zog xws li qib ntawm cov thee. Nyob rau hauv sib piv rau coking thee, thermal thee tsis tuaj yeem tsim coke thaum cov khoom cua sov.
Lub sij hawm caking muaj peev xwm piav txog cov coking thee vim nws hais txog qhov tsim nyog ntawm cov thee hloov mus ua coke. Muaj ntau hom coking thee, suav nrog cov roj coking tawv, nruab nrab coking thee, semi-soft coking thee, thiab pulverized thee.
Thermal Coal yog dab tsi?
Thermal thee yog ib hom thee uas yog siv los tsim lub zog. Hom thee no tuaj yeem tsim hluav taws xob thaum cua sov. Thermal thee kuj muaj npe hu ua steam thee. Hom thee no ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob thoob ntiaj teb. Cov khoom no yog lub hauv paus ntawm cua sov rau li 40% ntawm cov hluav taws xob tsim ntiaj teb no.
Txawm li cas los xij, vim muaj ntau yam kev xav txog ib puag ncig, kev siv cov thee thermal tsuas yog tam sim no. Nws tau dhau los ua qhov ua rau lub ntiaj teb sov sov. Raws li kev ntsuam xyuas, rov qab rau xyoo 2014, thermal thee tau nce siab hauv kev tsim hluav taws xob, thiab nws tau kwv yees tias qhov kev siv no yuav tuaj rau lub davhlau ya nyob twg nyob ib ncig ntawm 2050 yog tias peb sim txwv kev ua kom sov hauv ntiaj teb. Raws li qhov tshwm sim, feem ntau ntawm cov tuam txhab tau tso tseg kev nqis peev hauv cov thev naus laus zis tshiab.
Qhov txawv ntawm Coking Coal thiab Thermal Coal yog dab tsi?
Peb tuaj yeem faib cov thee rau hauv ntau pawg nyob ntawm daim ntawv thov. Thermal thee thiab coking thee yog ob hom thee. Qhov sib txawv tseem ceeb ntawm coking thee thiab thermal thee yog cov coking thee feem ntau yog siv los tsim cov coke zoo, thaum thermal coke tseem ceeb hauv kev tsim hluav taws xob. Thermal thee yog tsim tawm heev thiab muaj tus nqi qis thaum siv cov thev naus laus zis raug txwv vim kev xav txog ib puag ncig.
Hauv qab infographic qhia txog qhov sib txawv ntawm coking thee thiab thermal thee.
Summary – Coking Coal vs Thermal Coal
Coal tuaj yeem faib ua ntau pawg nyob ntawm daim ntawv thov. Thermal thee thiab coking thee yog ob hom thee. Qhov sib txawv tseem ceeb ntawm coking thee thiab thermal thee yog cov coking thee feem ntau yog siv los tsim cov coke zoo, qhov thermal coke tseem ceeb hauv kev tsim hluav taws xob.
