Nguva pfupi yadarika, mutori wenhau we "Economic Information Daily" akadzidza kuti China indasitiri yesimbi kabhoni peak yekumisikidza chirongwa uye kabhoni neutral tekinoroji nzira yemugwagwa yakanyatso kuumbwa.Pakati pese, chirongwa chinosimbisa kudzikiswa kwechitubu, kudzora kwakasimba kwemaitiro, uye kusimba kwekupedzisira-kwe-pombi hutongi, izvo zvakanangana nekubatana kwekudzikisa kusvibiswa uye kuderedzwa kwekabhoni, uye inosimudzira yakazara yakasvibira shanduko yehupfumi uye nzanga.
Indasitiri vemukati vakati kusimudzira kukwira kwekabhoni muindasitiri yesimbi ndeimwe yezviito gumi zve "carbon peaking".Kune indasitiri yesimbi, izvi zvose mukana uye dambudziko.Indasitiri yesimbi inoda kubata nemazvo hukama pakati pekusimudzira uye kuderedza emission, yakazara uye yakasarudzika, yenguva pfupi uye yepakati-kusvika-yakareba.
Muna Kurume gore rino, China Iron and Steel Association yakaratidza chinangwa chekutanga che "carbon peak" uye "carbon neutrality" muindasitiri yesimbi.Pamberi pa2025, indasitiri yesimbi ichawana peak mukuburitsa kabhoni;pakazosvika 2030, carbon emissions yeindasitiri yesimbi ichaderedzwa ne30% kubva pakakwirira, uye zvinotarisirwa kuti carbon emissions ichaderedzwa nematani mamiriyoni 420.Kuburitswa kwecarbon dioxide, sulfur dioxide, nitrogen oxides, uye zvinhu zvine mutsindo muindasitiri yesimbi nesimbi zviri pakati pevatatu vepamusoro muchikamu cheindasitiri, uye zvakakosha kuti indasitiri yesimbi nesimbi ideredze kuburitsa kabhoni.
"Ndiyo" mutsara wepazasi 'uye' mutsetse mutsvuku 'kurambidza zvakanyanya hutsva hwekugadzira.Kubatanidza mhedzisiro yekudzikisa huwandu huchiri rimwe remabasa akakosha eindastiri mune ramangwana. "Zvakaoma kumisa kukurumidza kukura kwekugadzirwa kwesimbi yemumba, uye isu tinofanira "maviri-mativi".Pasi pemashure kuti huwandu hwese hwakaoma kudonha zvakanyanya, yekupedzisira-yakaderera emission basa ichiri yakakosha nzvimbo yekutanga.
Parizvino, makambani esimbi anodarika mazana maviri nemakumi matatu munyika yose apedza kana kuti ari kuita zvekupedzisira-pasi-emission retrofits nematani anosvika 650 miriyoni ematani ekugadzira simbi isina kuchena.Kubva pakupera kwaGumiguru 2021, makambani makumi maviri nematanhatu esimbi mumatunhu matanhatu akashambadzira, ayo makambani gumi nemapfumbamwe akazivisa kuburitswa kwakarongeka, kuburitswa kusina kurongeka, uye kufambisa kwakachena, uye makambani manomwe akazivisa zvishoma.Zvakadaro, huwandu hwemakambani esimbi akaziviswa pachena ari pasi pe5% yehuwandu hwemakambani esimbi munyika.
Vanhu vataurwa pamusoro apa vakaratidza kuti mamwe makambani esimbi parizvino haana nzwisiso yakakwana yeakanyanya-yakaderera emission shanduko, uye makambani mazhinji achiri kumirira uye achiona, achisaririra kumashure kwehurongwa.Pamusoro pezvo, mamwe makambani haana nzwisiso yakakwana yekuoma kweshanduko, kutora immature desulfurization uye denitrification tekinoroji, kuburitswa kusina kurongeka, kutakura kwakachena, kutungamira kwezvakatipoteredza, kutarisa kwepamhepo uye mutemo, nezvimwewo, kune matambudziko mazhinji.Kune kunyangwe zviitiko zvemakambani anonyepa marekodhi ekugadzira, kugadzira mabhuku maviri, uye kunyepa emission yekutarisa data.
"Mune ramangwana, hutsi hwepamusoro-soro hunofanirwa kuitwa mukati memaitiro ese, maitiro ese, uye kutenderera kwehupenyu hwese."Munhu wacho akataura kuti kuburikidza nemutero, kusiyanisa kudzivirira kuchengetedzwa kwezvakatipoteredza, kusiyanisa mitengo yemvura, uye mitengo yemagetsi, kambani ichawedzera kuwedzera mutemo wekupedzisa ultra-low emission shanduko.Tsigira kusimba.
Pamusoro peiyo "mbiri yesimba rekushandisa kutonga", ichatarisa mukusimudzira girinhi dhizaini, kuchengetedza simba uye kuvandudza simba resimba, optimize mashandisiro esimba uye maitiro ekugadzirisa, kuvaka denderedzwa rehupfumi maindasitiri cheni, uye kushandisa budiriro yakaderera-kabhoni tekinoroji.
Vanhu vataurwa pamusoro apa vakati kuti budiriro yakasvibira, yakaderera-kabhoni uye yemhando yepamusoro muindasitiri yesimbi, inodawo kukwenenzvera magadzirirwo eindasitiri.Wedzera chiyero chekubuda kwechipfupi-maitiro emagetsi echoto chesimbi, uye kugadzirisa dambudziko rekushandisa simba rakawanda uye kuburitsa kwakanyanya kwekuita-refu-maitiro steelmaking.Gadzirisa chimiro chekuchaja, kukwidziridza cheni yeindasitiri, uye kuderedza zvakanyanya huwandu hwekuzvimiririra sintering, yakazvimirira inopisa rolling, uye yakazvimirira coking mabhizinesi.Gadzirisa chimiro chesimba, shandisa simba rakachena kutsiva kwemarasha-akabatidzwa maindasitiri echoto, bvisa majenareta egasi, uye wedzera chikamu chemagetsi egirinhi.Panyaya yechimiro chekufambisa, wedzera chikamu chekutakura kwakachena kwezvinhu uye zvigadzirwa kunze kwechirimwa, shandisa njanji uye kutamisa mvura kwepakati nepakati uye kureba, uye kutora pombi mikoto kana mota nyowani dzemagetsi mapfupi nepakati madaro;ita zvizere kuvakwa kwebhandi, njanji, uye roller masisitimu ekufambisa mufekitori kusvika pamwero mukuru Kuderedza huwandu hwekufambisa kwemotokari mufekitori uye kudzima chechipiri chekufambisa kwezvinhu mufekitori.
Pamusoro pezvo, iko iko kusangana kweindasitiri yesimbi kuchiri kuderera, uye danho rinotevera rinofanira kunge riri rekuwedzera kubatanidzwa uye kurongazve uye kubatanidza nekugadzirisa zviwanikwa.Panguva imwecheteyo, simbisa kuchengetedzwa kwezvinhu zvakadai sesimbi.
Iyo kabhoni yekudzikisa dhizaini yemakambani anotungamira yakawedzera.Sekambani huru yeChina yesimbi uye parizvino iri pekutanga pasi rose mukubuda kwegore, Baowu yekuChina yakabuda pachena kuti inovavarira kuwana carbon peak muna 2023, inokwanisa kuderedza kabhoni ne30% muna 2030, uye kuderedza kabhoni yayo. emissions ne50% kubva pakakwirira muna 2042.
“Muna 2020, simbi yekuChina yeBaowu inosvika matani 115 miriyoni, yakagovaniswa mumabhesi gumi nemanomwe.China's Baowu's refu simbi yekugadzira simbi inoita ingangoita 94% yehuwandu.Kudzikiswa kweCarbon emission kunoisa dambudziko rakakura kuBaowu yekuChina kupfuura vezera rayo."China Baowu Bato Munyori uye Sachigaro Chen Derong vakati China Baowu inotungamira mukuzadzisa kabhoni kusarerekera.
"Gore rapfuura takamisa zvakananga chirongwa cheZhangang chekutanga chemoto, uye takaronga kukurumidza kuvandudzwa kweiyo low-carbon metallurgical tekinoroji uye kuita kuvaka kwehydrogen-based shaft furnace tekinoroji yecoke oven gasi."Chen Derong akati, kugadzira hydrogen-yakavakirwa shaft choto chakananga kudzikisa ironmaking process, Iyo simbi yekunyungudutsa inotarisirwa kuwana pedyo-zero kabhoni emissions.
Hegang Group inoronga kuwana carbon peak muna 2022, kuderedza carbon emissions nezvikamu zvinopfuura gumi kubva pakakwirira muna 2025, kuderedza carbon emissions nezvikamu zvinopfuura makumi matatu kubva muzana kubva pakakwirira muna 2030, uye kuwana kusarerekera kwekabhoni muna 2050. Ansteel Group inoronga kuita kuwana huwandu hwepamusoro mukuburitswa kwekabhoni panosvika 2025 uye kubudirira muindasitiri yekucheka-kumucheto yakaderera-kabhoni metallurgical tekinoroji muna 2030, uye kuyedza kudzikisa yakazara kabhoni emissions ne30% kubva pamusoro pe2035;ramba uchigadzira yakaderera-kabhoni metallurgical tekinoroji uye uve indasitiri yesimbi yenyika Makambani makuru ekutanga esimbi kuti awane kusarerekera kwekabhoni.
