Indlela yenguqu eluhlaza yoshishino lwentsimbi

Impumelelo ephawulekayo yenziwe ekugcineni amandla kunye nokunciphisa ukukhutshwa kwishishini lentsimbi

INkongolo yeSizwe ye-18 yeQela lamaKomanisi laseTshayina idibanise inkqubela-phambili yendalo kwisicwangciso sesihlanu-kwisinye sokwakha usoshiyali ngeempawu zamaTshayina, kwaye yakwenza kwacaca ukuba kufuneka sikhuthaze ngamandla inkqubela phambili yendalo. Ushishino lwentsimbi kunye nentsimbi, njengoshishino olusisiseko kuphuhliso loqoqosho lwesizwe, luthatha ugcino lwamandla kunye nokunciphisa ukukhutshwa kwegesi njengeyona ndlela iphambili yokuphumelela, ubuvulindlela obuthe gqolo nokuqhubela phambili, kwaye luzuze iziphumo ezimangalisayo.

Okokuqala, ngokubhekiselele ekuthinteleni nasekulawuleni ukungcola, imboni yensimbi yenza uluhlu lweenguqu zembali ukususela kwi-2012.

Impumelelo yembali yenziwe kwidabi lokukhusela isibhakabhaka esiluhlaza, ukukhuthaza uphuhliso oluluhlaza kunye nomgangatho ophezulu woshishino lwentsimbi. Umzekelo, i-flue gas desulfurization, i-denitrification kunye neendawo zokususa uthuli ezinje nge-sintering, ii-oveni ze-coke kunye nezixhobo zombane ezibaselwa ngamalahle ezibonelelwe ngokwazo ziye zaba sisixhobo esisemgangathweni, kwaye imigangatho yokukhupha ungcoliseko iphezulu kakhulu kunaleyo yamazwe aphuhlileyo anjengeJapan, eMzantsi. eKorea naseUnited States. Ukulawulwa kakuhle kunye nokunyangwa kwezinto ezikhutshwayo ezingalungelelanisiweyo kwenza ukuba amashishini ensimbi athathe inkangeleko entsha; Ukukhuthazwa ngamandla kaloliwe ojikelezayo kunye neelori ezisindayo zamandla amatsha kuphucule ngokufanelekileyo inqanaba lothutho olucocekileyo lwekhonkco lothutho kushishino lwentsimbi kunye nentsimbi.

La manyathelo ngamanyathelo angundoqo olawulo longcoliseko lomoya kwishishini lentsimbi.” U-Wenbo uthe ngokweenkcukacha-manani ezingaphelelanga, utyalo-mali olupheleleyo ekuguqulweni kwe-ultra-low emissions yamashishini ensimbi idlule i-yuan eyi-150 yeebhiliyoni. Ngemizamo eqhubekayo, Inani le-A-level amashishini kunye nokusebenza kokusingqongileyo kunye nenani le-4A kunye ne-3A yeefektri zokhenketho eziye zavela kwi-iron kunye ne-iron kushishino lwentsimbi, ukubeka isiseko esiluqilima sokwakhiwa kwempucuko yendalo kunye nokwenza isibhakabhaka sasekhaya sibe luhlaza. nzulu, icace ngakumbi kwaye inde.

Okwesibini, malunga nokonga umbane kunye nokunciphisa ukusetyenziswa, impumelelo ephawulekayo yenziwe ekugcinweni kwamandla kunye nokunciphisa ukusetyenziswa kwamandla ngokuqhubekayo okonga amandla obugcisa, ukugcinwa kwamandla okwakhiwa, ukugcinwa kwamandla kunye nokugcinwa kwamandla enkqubo. Ngokwezibalo, ngo-2021, ukusetyenziswa kwamandla okubanzi ngetoni nganye yentsimbi yesizwe esikhulu kunye namashishini entsimbi aphakathi afikelela kuma-549 kg amalahle aqhelekileyo, ezantsi malunga ne-53 kg yamalahle asemgangathweni xa kuthelekiswa no-2012, ukuhla kwe-9%. Kwangaxeshanye, ngo-2021, ubushushu benkunkuma kunye nenqanaba lokuphinda lisetyenziswe kumashishini entsimbi angundoqo naphakathi aphuculwe kakhulu. Xa kuthelekiswa ne-2012, izinga lokukhululwa kwegesi ye-oven ye-coke kunye ne-blast furnace gas yehla malunga ne-41% kunye ne-71% ngokulandelanayo, kunye nexabiso lokubuyisela insimbi ye-converter gas tons yanda malunga ne-26%.

“Ukongezelela kuphuculo lwezi zalathisi, indlela yolawulo lwamandla kushishino lwentsimbi kunye nentsimbi iphinda iguqulwe ngokuthe ngcembe ukusuka kulawulo lwamava ukuya kulawulo lwale mihla, ukusuka kwisebe elilodwa lolawulo lokonga amandla ukuya kushishino olubanzi lwenguqu yokunciphisa amandla entsebenziswano, ukusuka kwidatha yedatha eyenziweyo. uhlalutyo kwidijithali, utshintsho olukrelekrele.
