Te Whakataki me nga Waahanga o nga Kaihanga Whakaiti Catalytic Reduction (SCR).

Ka whakamahia e nga whakakōkī whakaheke whakakōkī (SCR) he māngai whakaheke ki te tauhohenga ki te NOx i roto i te hau rewharewha, ka whakaputa i te N2 me te H2O kore-waiwai me te parahanga-kore, i raro i te mahi a te whakakōkī.

Ko te pāmahana tauhohenga e whakatau ana ehara i te mea ko te tere tauhohenga o nga tauhohenga engari ko te tauhohenga o te whakakorikori SCR. Ko te tikanga, ko te teitei ake o te pāmahana tauhohenga ka tere ake te tere o te tauhohenga me te nui ake o te mahi whakakorikori, ka iti ake te mokowā tauhohenga me te rōrahi reactor mo ia waahanga wae. Ma te whakaaro ki te whakamahana tauhohenga, te mana o te punaha, me te awhe pāmahana pai o te whakakorikori, ko te nuinga o te waa ka whakatauhia nga pāmahana punaha SCR i waenga i te 320 me te 420 tohu.

Ko te tere o te mokowā he tawhā hoahoa matua mō ngā whakakōkī whakaheke whakakōkī (SCR). Ka ine i te wa noho o te rewharewha rewharewha (te hau rewharewha mākū i raro i nga tikanga paerewa) i roto i te rōrahi whakakōkī, ā, ka whakatauhia mēnā ka tauhohe katoa ngā tauhohenga. Ka whakaawe hoki i te whiu o te anga whakakorikori reactor me te ngaronga waku o te hau reactor.

Ko te kounga o te tauira rere hau rewharewha e whakatau ana i te kaha o te whakakorikori. Ko te tauira rere hau rewharewha e tika ana ehara i te whakanui noa i te whakamahinga whakakorikori engari ka whakaitihia te mate waku. I roto i te hoahoa miihini, me ata whakaaro te waahi rere hau rewharewha. Ko nga waahi werohanga haukini me whai tikanga ngangau kia pai ai te uru ki te hau rewharewha me te hanga i tetahi rohe rere riterite.
