Coal feem ntau yog siv los ua roj. Thaum cov thee tau paub thiab siv tau ntau txhiab xyoo, nws cov kev siv tau txwv kom txog rau thaum Industrial Revolution. Nrog rau kev tsim lub tshuab hluav taws xob, kev siv hluav taws xob tau nce ntxiv. Qee cov hlau thiab hlau ua thiab lwm cov txheej txheem kev lag luam hlawv thee.
Kev rho tawm thiab siv cov thee ua rau tuag ntxov ntxov thiab muaj mob. Kev siv cov thee puas tsuaj rau ib puag ncig, thiab nws yog qhov loj tshaj plaws ntawm cov pa roj carbon dioxide uas ua rau muaj kev hloov pauv huab cua. Kaum plaub txhiab tons ntawm carbon dioxide tau tawm los ntawm kev hlawv thee hauv xyoo 2020, uas yog 40% ntawm tag nrho cov fossil roj emissions[8] thiab ntau dua 25% ntawm tag nrho lub ntiaj teb lub tsev cog khoom emissions. Raws li ib feem ntawm kev hloov pauv hluav taws xob thoob ntiaj teb, ntau lub tebchaws tau txo lossis tshem tawm lawv txoj kev siv hluav taws xob thee. Tus Thawj Fwm Tsav Tebchaws United Nations tau hais kom tsoomfwv txwv tsis pub tsim cov chaw tsim hluav taws xob tshiab los ntawm 2020. Kev siv cov thee thoob ntiaj teb yog 8.3 billion tonnes hauv 2022. Kev thov cov thee thoob ntiaj teb tau teem tseg kom nyob twj ywm ntawm cov ntaub ntawv nyob rau hauv 2023. Kom ua tau raws li Paris Daim ntawv cog lus lub hom phiaj ntawm kev ua kom lub ntiaj teb sov sov hauv qab no. 2 ° C (3.6 ° F) thee siv yuav tsum tau halve los ntawm 2020 txog 2030, thiab "phasing down" thee tau pom zoo nyob rau hauv Glasgow Climate Pact.
Cov neeg siv khoom loj tshaj plaws thiab cov neeg xa khoom ntawm cov thee hauv xyoo 2020 yog Tuam Tshoj, uas suav txog yuav luag ib nrab ntawm lub ntiaj teb cov khoom siv hluav taws xob txhua xyoo, ua raws li Is Nrias teb nrog rau ib feem kaum. Indonesia thiab Australia xa tawm ntau tshaj plaws, ua raws li Russia.
Yam khoom
Nyob rau hauv 1985, Datong Locomotive Works pom tau hais tias hluav taws xob locomotives yog qhov tseem ceeb txoj kev loj hlob ntawm Tuam Tshoj railway locomotive thiab dov Tshuag lag luam nyob rau hauv lub neej yav tom ntej, thiab muab tso rau pem hauv ntej lub tswv yim tsim khoom ntawm "Nanzhu (Zhuzhou Electric Locomotive Works) thiab Datong Locomotive Works".
Shaoshan Hom 3 hluav taws xob locomotive yog kuv lub teb chaws thib ob tiam 6-axle neeg nrog caij thiab tsheb thauj mus los. Lub locomotive txais tus choj-hom tag nrho-yoj rectification thiab paub txog thyristor theem-tswj tus voltage tswj. Lub locomotive txais ib-theem AC 25kV 50Hz voltage system thiab muaj kev khiav hauj lwm siab tshaj plaws ntawm 100km / h.
Lub SS3B tsau hnyav hluav taws xob locomotive yog 12-axle freight electric locomotive. Nws muaj ob qhov zoo tib yam 6-qag locomotives txuas los ntawm ib lub coupler thiab ib lub tshuab cua. Ob ntu yog nruab nrog cov khoom siv hluav taws xob high-voltage connectors, tswj cables, thiab kev tiv thaiv network. Kab thiab cua system tswj ducts. Tag nrho lub tsheb tuaj yeem tswj tau synchronously ntawm txhua lub cab. Lub locomotive txais ib-theem fais fab zaus system, voltage 25kV, AC-DC kis tau tus mob, thiab lub siab tshaj plaws kev khiav hauj lwm ceev ntawm lub locomotive yog 100km / h.
Shaoshan 4 txhim kho hluav taws xob locomotive yog 8-axle freight locomotive. Lub locomotive muaj ob zoo tib yam plaub-axle locomotives txuas nrog ib tug coupler thiab ib tug windshield. Ob lub rooj cob qhia yog nruab nrog high-voltage connectors rau cov hluav taws xob system, reconnection tswj cables thiab cua nres system tswj ducts. Tag nrho lub tsheb tuaj yeem synchronously tswj los ntawm tus tsav tsheb cab ntawm ib qho ntawm lub tsheb. Ob lub locomotives tseem tuaj yeem sib cais thiab siv nws tus kheej ua plaub-qag locomotive.
