I tēnei wā, he nui te pēhanga tiaki taiao o te wheketere hanga rino hurihuri o te oumu. I roto i ēnei, ko te pūnaha tango puehu o te hau paipa oumu hurihuri te mea nui rawa atu, ā, me whakatinana he panoni ma kia tutuki ai he tukunga tino iti. Nō reira, ko te whiriwhiri me te whakamahi i te hangarau tango puehu oumu hurihuri whai hua, haumaru, iti te whakapaunga kua noho hei kaupapa matua mā ngā umanga rino me te rino.
He painga anō tō te tikanga mākū me te tikanga maroke mō te huri i te tango puehu i roto i te oumu.
Ko te hangarau tango puehu mākū o te oumu hurihuri e whakarāpopototia ana ko OG. Ko te OG te whakarāpopototanga o te Oxygen rotating furnace Gas Recovery i te reo Ingarihi, arā, ko te whakaora hau o te oumu hurihuri hāora. Mā te whakamahi i te hangarau OG, ka puta he nui o te hau CO wera-teitei me te kukū-teitei i roto i te oumu nā te kaha o te tauhohenga waikura i te wā e pupuhi ana. Ka pehia e te hau paowa te urunga mai o te hau huri noa mā te hiki i te kākahu me te whakahaere i te pēhanga hau paowa ki roto i te taupoki. Mēnā kāore i tahuna, ka whakamahia e te hangarau te paowa whakamatao mimiti hei whakamatao i te hau paowa, ā, i muri i te purenga e te kaikohi puehu ngongo Venturi e rua-wāhanga, ka uru ki te pūnaha whakaora me te tuku hau.
Ko te hangarau tango puehu maroke o te oumu hurihuri e whakarapopototia ana koLTTeLTI whakawhanakehia ngātahitia tēnei tikanga e Lurgi rāua ko Thyssen i Tiamana.LTKo te whakarāpopototanga tēnei o ngā ingoa o ngā kamupene e rua. Ka whakamahia e tēnei hangarau te whakamatao mimiti hei whakamatao i te hau paru, ā, i muri i te purenga mā te pūwhakaoho hiko maroke porotaka, ka uru ki te pūnaha whakaora me te tuku hau. I tīmata te whakamahi i tēnei ture i roto i ngā kaupapa whakaora hau i te tau 1981.
He nui te haumitanga kotahi mō te hangarau tango puehu maroke o te oumu hurihuri, he uaua te hanganga, he maha ngā mea e pau ana, ā, he tino uaua te hangarau. He iti iho i te 20% te tere whakatairanga mākete i tōku whenua. Hei tāpiri, ka whakamahia e te hangarau tango puehu maroke he pūwero hiko maroke nui hei tango i te puehu tuatahi o te oumu hurihuri matotoru. He ngāwari te kohikohi puehu i te kaikohi puehu, ā, he koretake te tukunga puehu.
Ki te whakatauritea ki te tukanga tango puehu maroke, he māmā te hanganga o te tukanga tango puehu mākū OG, he iti te utu, ā, he pai te whakapai ake, engari he ngoikoretanga anō hoki pērā i te nui o te whakapaunga pūngao, te nui o te wai e pau ana, te uaua o te maimoatanga paru, me te nui o ngā utu whakahaere. Heoi anō, ka horoia e te hangarau tango puehu mākū te puehu katoa ki roto i te wai ahakoa te rahi o te matūriki, ka hua ake he nui te paru tango puehu. Ahakoa kua whakapaitia tonutia te taumata hangarau o ngā tukanga tango puehu maroke me te mākū i roto i te tukanga whakawātea, kāore anō kia whakatauhia ō rātou hapa ā-roto.
Hei whakautu i te āhuatanga o runga ake nei, kua whakaarohia e ngā tohunga ahumahi te hangarau tango puehu haurua-maroke i ngā tau tata nei, kua whakatairangahia i Haina. I tēnei wā, ko te maha o ngā oumu hurihuri e whakamahi ana i te hangarau tango puehu haurua-maroke kua nui ake i te maha o ngā oumu hurihuri e whakamahi ana i te hangarau tango puehu maroke. Ka whakamahia e te tukanga tango puehu haurua-maroke he whakamatao mimiti maroke hei whakaora i te 20%-25% o te pungarehu maroke, e pupuri ana i ngā painga o te tango puehu mākū me te wikitoria i ngā hapa o ngā hangarau tango puehu maroke me te mākū. Ina koa, ka taea e tēnei hangarau te whakarerekē i te tukanga tango puehu mākū me te kore e hiahiatia te wetewete katoa me te mahi anō pērā i te tukanga tango puehu maroke, kia taea ai te pupuri i ngā whakaurunga taketake ki te taumata teitei me te penapena i ngā utu haumi.
