Cov khoom siv thee yog siv rau hauv peb thaj chaw tseem ceeb: tsim hluav taws xob, tsim khoom siv hlau, siv tsev neeg. Cov ntawv teev npe yuav tsum muaj qib thee nrog cov khoom tshwj xeeb thermal.

Cov tswv tsev muaj kev txhawj xeeb txog tus nqi ntawm ib tuj ntawm briquettes thiab qhov zoo "kom tsis txhob tuag." Cov nqi hluav taws xob txhawj xeeb txog dab tsi raw khoom yuav rau lub caij ntuj no kom cua sov tsis raug nqi zoo nkauj.

Kev lag luam fais fab xav tau cov nqi calorific siab concentrates los tsim hluav taws xob.

Metallurgists uas yaj hlau thiab hlau xaiv cov khoom tsim coke nrog cov txheej txheem siab ceev kom microcracks tsis tsim.

Environmentalists nrhiav kom pom qhov tsim nyog thee tsis nyob rau hauv kev faib tawm los xam tus nqi ntawm qhov cuam tshuam tsis zoo ntawm huab cua thaum lub sij hawm tsim khoom siv cov khoom siv hluav taws xob.

Tus lej system

Yuav kom xaj los ntawm cov chaw tsim khoom thiab siv cov ntaub ntawv carbon rationally, koj yuav tsum nkag siab txog qhov ntsuas ntawm cov qib.

Lub npe muaj cuaj lub npe. Txhua tus yog encoded nrog cov tsiaj ntawv ntawm cov tsiaj ntawv Lavxias. Kev txiav txim siab qib ntawm cov thee pib nrog qhov tshwj xeeb ntawm carbon:

anthracite -A;
lignite – B;
gas - G;
ntev-nplaim – D;
bold – F;
coke - K;
lean sintered - OS;
low caking – SS;
skinny – T.

Cov khoom siv ntawm raw khoom

Qib ntawm cov thee yog tus cwj pwm los ntawm qhov feem pua ntawm cov tshuaj nquag - carbon. Cov ntsiab lus siab tshaj plaws hauv anthracite yog 90%, thiab cov ntsiab lus qis tshaj plaws yog xim av, 76%.

Cua sov yam tsis muaj pa tshuab ua rau cov thee decompose rau hauv cov pa roj thiab cov kua dej. Qhov parameter no yog cov tshuaj tsis haum. Oi yog tus cwj pwm thib ob ntawm lub npe thee. Qhov siab tshaj plaws tawm los ntawm ntau hom xim av yog 41%. Anthracite muaj qhov qis tshaj plaws ntawm cov khoom tsis hloov pauv - 8%. Qhov feem pua ntawm cov volatiles hu ua carbonation.

Tus yam ntxwv thib peb yog tus nqi calorific. Nws ntsuas hauv kcal / kg. Qhov tsawg kawg nkaus tus nqi ntawm net calorific nqi ntawm cov xim av coal yog 3900 kcal / kg. Tus nqi siab tshaj plaws yog rau anthracite. Ntawm no, 7500 kilocalories raug tso tawm thaum 1 kg ntawm cov khoom raug hlawv.

Cov khoom thib ob ntawm cov thermal decomposition ntawm thee yog coke, lossis kinglet.

Thaum yuav cov khoom siv raw, cov neeg siv saib tus nqi-zoo piv.

Nyob rau hauv ferrous metallurgy, cov khoom G thiab G tau siv. Hauv kev lag luam hluav taws xob, cov khoom siv nrog lub npe OS, SS, thiab T yog siv. Briquettes A, G, thiab D raug thauj mus rau hauv boiler furnaces.

Underground storeroom assortment

Thaum tsim daim npav thee hom, ntxiv rau kev faib hom, kev faib tawm ntau yam yog siv. Yog lilub npe muaj ob lub cim: lub hom thiab qhov loj ntawm cov granules. Tus txiv neej hu ua ntau yam yog ib tug kws sau paj huam thiab romantic:

P - reservoir;
K - nrig;
O - walnut;
M - me;
S - noob;
Ш - shtyb;
P - tus kheej.

P thiab R yog qhov loj ntawm 20 - 30 centimeters. Cov no yog cov loj tshaj plaws. Shtyb yog ib qho me me txog li ib thiab ib nrab centimeters loj.

Ib qho piv txwv ntawm kev txiav txim siab qib thee: hauv daim npav ntawm cov khoom lag luam thee, pawg ntawv AP txhais tau tias seam anthracite nrog ib feem me me ntawm 0.2 - 0.3 m.

Class B raw khoom

Lub pob zeb loj dua, qhov zoo ntawm cov thee. Txhawm rau txiav txim siab qhov kev loj hlob, peb tau qhia lub tswv yim ntawm vitrinite reflection OM - qhov cuam tshuam ntawm cov nroj tsuag organic teeb meem nyob rau hauv muaj pes tsawg leeg ntawm thee. Qhov taw qhia tau txiav txim raws li hauv qab no - ib lub teeb monochrome yog qhia rau cov qauv pob zeb polished. Tom qab ntawd, qhov kev siv ntawm lub teeb pom kev yog ntsuas.

Qib ntawm cov thee sib txawv ntawm qhov loj ntawm pob zeb. Nyob rau hauv cov xim av coals, lub vitrinite reflection Performance index yog tsawg dua 0.6%, qhov tsim ntawm volatile Cheebtsam yog ntau tshaj 41%. Rau kev sib piv, RH ntawm anthracite yog 2.59%. Tus nqi calorific ntawm qib B yog nyob rau hauv thaj tsam ntawm 3900 txog 4500 kcal / kg nyob ntawm cov av noo:

1B - 40% lossis ntau dua;
2B - los ntawm 30 txog 40%;
3B - tsawg dua 30%.

Qib B thee feem ntau yog ntoo ntawm qhov so, haus luam yeeb thaum combustion. Nws tsuas zoo dua yog nws tus nqi qis.

Nyob rau hauv Russia, xim av thee yog mined nyob rau hauv loj ntim nyob rau hauv Soltonsky, Tunguskathiab Kansk-Achinsk phiab. Cov khoom me me hauv Primorsky Krai, hauv Chelyabinsk cheeb tsam nyob rau sab hnub tuaj txoj kab nqes ntawm Ural Toj siab.

Brown thee tsis yog siv roj xwb, tab sis kuj yog cov khoom siv raw rau kev tsim cov roj thiab roj, chiv thiab cov khoom siv hluavtaws.
