Nkag siab Semi-Soft Coal: Cov Khoom, Kev Siv, thiab Kev Txiav Txim Siab

Kab lus no muab cov ntsiab lus dav dav ntawm semi-mos thee, tshawb xyuas nws cov khoom, kev siv, thiab cov yam ntxwv uas yuav tsum tau xav txog thaum ua haujlwm nrog hom thee no. Peb delve rau hauv nws cov yam ntxwv txawv, muab piv rau lwm hom thee thiab qhia txog nws cov kev siv tshwj xeeb hauv ntau qhov kev lag luam. Peb kuj tham txog qhov cuam tshuam ib puag ncig cuam tshuam nrog nws txoj kev siv. Kawm txog qhov zoo thiab qhov tsis zoo ntawm kev siv semi-mos thee thiab nws lub luag haujlwm hauv lub ntiaj teb lub zog toj roob hauv pes.

Semi-Soft Coal yog dab tsi?

Semi-soft thee, tseem hu ua sub-bituminous thee, sawv cev rau theem hauv cov txheej txheem coalification ntawm lignite (xim av coal) thiab bituminous thee. Nws yog tus cwj pwm los ntawm nws cov khoom nruab nrab, ntog ntawm cov softer, tsawg zog-dense lignite thiab nyuaj, siab dua-zog bituminous thee. Nws cov ntsiab lus noo noo yog qhov siab dua piv rau cov thee bituminous, cuam tshuam rau nws cov kev tuav thiab cov yam ntxwv combustion. Cov khoom tshwj xeeb ntawm semi-mos thee tuaj yeem sib txawv heev nyob ntawm nws cov keeb kwm geological thiab tsim cov xwm txheej. Kev nkag siab txog cov kev hloov pauv no yog qhov tseem ceeb rau nws txoj kev siv tau zoo thiab siv tau zoo.

Cov khoom ntawm Semi-Soft Coal

Moisture Content thiab tshauv ntsiab lus

Ib tug yam ntxwv tseem ceeb ntawm semi-mos thee yog nws cov ntsiab lus siab noo noo, feem ntau yog li ntawm 15% mus rau 30%. Qhov no cuam tshuam rau nws lub zog ceev thiab yuav tsum tau hloov kho hauv cov txheej txheem combustion. Cov ntsiab lus tshauv, ib qho kev ntsuas ntawm cov khoom uas tsis yog-combustible, kuj txawv heev tab sis feem ntau ntog nyob rau hauv ib tug tej yam. Cov dej noo ntau dua feem ntau txhais kom qis dua cov nqi cua sov ib chav tsev piv rau cov thee bituminous. Kev txiav txim siab ntawm cov dej noo thiab cov hmoov tshauv yog qhov tseem ceeb rau kev siv tau zoo thiab tus nqi.

Cov nqi cua sov thiab cov ntsiab lus sulfur

Semi-soft thee muaj cov nqi cua sov qis dua li cov thee bituminous tab sis siab dua lignite. Cov nqi cua sov no, qhia nyob rau hauv British Thermal Units (BTU) ib phaus lossis megajoules ib kilogram, qhia tias lub zog tso tawm thaum combustion. Cov ntsiab lus sulfur yog lwm qhov tseem ceeb, cuam tshuam rau ib puag ncig kev txiav txim siab vim yog sulfur dioxide emissions. Tsawg sulfur semi-mos thee feem ntau nyiam rau ib puag ncig vim li cas.

Volatile Matter thiab Fixed Carbon

Lub volatile teeb meem cov ntsiab lus nyob rau hauv semi-mos thee influences nws tus cwj pwm combustion. Cov ntsiab lus ntau dua volatile feem ntau txhais tau hais tias cov thee reactive ntau dua uas hlawv tau yooj yim dua. Tsau cov pa roj carbon monoxide, cov khoom siv hluav taws xob uas tseem tshuav tom qab cov teeb meem tsis zoo raug tshem tawm, ua rau muaj txiaj ntsig zoo rau tag nrho cov nqi cua sov. Qhov piv ntawm cov teeb meem tsis haum rau cov pa roj carbon monoxide yog qhov tseem ceeb hauv kev xaiv cov cuab yeej hluav taws xob tsim nyog.

Kev siv Semi-Soft Coal

Semi-soft thee pom daim ntawv thov nyob rau hauv ntau yam lag luam, txawm hais tias nws siv feem ntau cuam tshuam los ntawm nws cov khoom thiab muaj. Nws yog feem ntau siv nyob rau hauv kev tsim hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam uas muaj ntau reserves. Vim nws cov nqi cua sov qis, nws yuav xav tau kev hloov kho rau cov qauv tsim hluav taws xob uas twb muaj lawm lossis siv cov cuab yeej siv hluav taws xob tshwj xeeb. Nws kuj tseem tuaj yeem siv rau hauv cov txheej txheem kev lag luam uas xav tau cua sov, txawm hais tias muaj cov ntsiab lus noo noo ntau dua yuav tsum tau hloov kho rau cov txheej txheem tsis.

Environmental Considerations

Kev siv ntawm semi-mos thee, zoo li cov roj fossil, muaj kev cuam tshuam ib puag ncig. Cov txheej txheem combustion tso tawm cov pa roj carbon dioxide feem ntau, ua rau muaj kev hloov pauv huab cua. Tsis tas li ntawd, cov ntsiab lus ntawm sulfur tuaj yeem ua rau sulfur dioxide emissions, ib qho tseem ceeb rau cov kua qaub los nag. Cov mining thiab kev thauj mus los ntawm semi-mos thee kuj tuaj yeem ua rau kev puas tsuaj ib puag ncig. Kev txo qis cov kev cuam tshuam ib puag ncig no yog qhov tseem ceeb, thiab kev nce qib hauv cov thee huv si thev naus laus zis tau ua raws.

Kev sib piv nrog lwm hom Coal

Nco tseg: Cov kab uas tau muab rau cov dej noo, cov nqi cua sov, thiab cov ntsiab lus sulfur yog kwv yees thiab tuaj yeem sib txawv heev nyob ntawm seb cov coal seam tshwj xeeb thiab nws qhov chaw nyob. Rau cov ntaub ntawv meej, sab laj txog cov kev tshawb fawb geological thiab cov ntaub ntawv kev lag luam.

Yog xav paub ntxiv txog cov peev txheej thee thiab cov ntawv thov kev lag luam, koj tuaj yeem tham nrog cov kws tshaj lij kev lag luam thiab cov koom haum tshawb fawb. Tiv tauj peb ntawm Sab hauv Mongolia Xinxin Silicon Kev Lag Luam Co., Ltd kom paub ntau ntxiv txog peb txoj kev cog lus rau kev ua lag luam muaj txiaj ntsig.
