Peb mam li delve rau hauv cov yam ntxwv uas txhais tau hais tias txhua hom, qhia txog lawv qhov haum rau ntau hom kev lag luam. Kawm paub txog kev thov thoob ntiaj teb thiab kev muab khoom siv rau cov khoom siv hluav taws xob tseem ceeb thiab kev lag luam.

Txhais Thermal Coal

Khoom thiab yam ntxwv

Thermal thee, tseem hu ua steam thee, feem ntau yog siv los tsim hluav taws xob hauv cov chaw tsim hluav taws xob. Nws cov yam ntxwv tseem ceeb yog nws cov nqi calorific siab, lub ntsiab lus nws tso tawm ib qho tseem ceeb ntawm cov cua sov thaum hlawv. Lwm cov khoom tseem ceeb suav nrog nws cov ntsiab lus noo noo, cov hmoov tshauv, thiab cov ntsiab lus ntawm cov sulfur, tag nrho cov uas cuam tshuam rau nws cov kev ua kom combustion efficiency thiab ib puag ncig. Zoo dua thermal thee yuav muaj cov hmoov tshauv thiab cov sulfur qis dua, ua rau kom huv si hlawv thiab muaj kuab paug tsawg. Cov khoom tshwj xeeb ntawm thermal thee tuaj yeem sib txawv heev nyob ntawm nws cov keeb kwm geological thiab tsim.

Daim ntawv thov

Thawj daim ntawv thov ntawm thermal thee yog nyob rau hauv lub zog tsim. Nws yog siv los ua cua sov dej, tsim cov chav uas tsav turbines los tsim hluav taws xob. Thaum nws txoj kev siv tau poob qis hauv qee thaj tsam vim muaj kev txhawj xeeb ib puag ncig thiab kev nce ntawm lub zog tauj dua tshiab, thermal thee tseem yog qhov tseem ceeb ntawm hluav taws xob thoob ntiaj teb. Ib txhia thermal thee cov qib kuj tseem tsim nyog rau cov txheej txheem cua sov.

Txhais Metallurgical Coal

Khoom thiab yam ntxwv

Tsis zoo li thermal thee, metallurgical thee, tseem hu ua coking thee, yog qhov tseem ceeb rau kev lag luam steelmaking. Nws cov yam ntxwv txhais yog nws cov ntsiab lus carbon siab thiab cov ntsiab lus tsis tshua muaj suab nrov. Qhov no tso cai rau nws mus rau coking-ib txheej txheem uas nws tau rhuab thaum tsis muaj huab cua, hloov nws mus rau hauv coke, ib tug ntxeem tau roj tseem ceeb rau hlau ore txo nyob rau hauv blast furnaces. Qhov zoo ntawm metallurgical thee yog txiav txim los ntawm qhov tsis xws li nws cov khoom coking, cov ntsiab lus tshauv, thiab cov ntsiab lus sulfur. Cov qib tsis raug ntawm cov kev txwv no ncaj qha cuam tshuam rau qhov zoo ntawm cov coke tsim, cuam tshuam rau kev ua tau zoo thiab lub zog ntawm cov hlau tshwm sim.

Daim ntawv thov

Thawj daim ntawv thov rau metallurgical thee yog nyob rau hauv zus tau tej cov coke rau blast furnaces nyob rau hauv lub steelmaking txheej txheem. Coke muab cov cua sov tsim nyog thiab txo tus neeg sawv cev los hloov cov hlau ore rau hauv hlau, uas yog tom qab ntawd ua kom zoo rau hauv cov hlau. Qhov kev thov rau metallurgical thee yog ncaj qha khi rau ntiaj teb steel ntau lawm.

Kev ua lag luam Dynamics thiab yav tom ntej Trends

Kev lag luam thoob ntiaj teb rau ob qho tib si thermal thiab metallurgical thee yog nyob rau hauv qhov kev hloov pauv tseem ceeb cuam tshuam los ntawm cov yam xws li kev loj hlob ntawm kev lag luam, kev tswj hwm hluav taws xob, thiab kev tswj hwm ib puag ncig. Kev tsom mus rau kev txo qis cov pa roj carbon emissions yog ua rau kev poob qis hauv kev thov rau thermal thee nyob rau hauv ntau lub cheeb tsam, thaum qhov kev thov rau metallurgical thee tseem nyob ruaj khov, khi rau qhov kev xav tau ntawm cov hlau tsis tu ncua hauv kev tsim kho thiab kev tsim kho vaj tse. Kev nce qib ntawm cov thev naus laus zis thiab kev txhim kho cov khoom siv lwm yam kuj cuam tshuam rau lub sijhawm ntev rau ob hom thee. Rau cov ncauj lus kom ntxaws txog kev lag luam, cov peev txheej xws li International Energy Agency (IEA) https://www.iea.org/ muab kev nkag siab zoo.
