Ngakolunye uhlangothi, izinqubomgomo eziqinile zokuvikela imvelo ziphinde zikhuthaze abakhiqizi bejeneretha yesitimu ukuthi baqhube ukuqamba okusha kwezobuchwepheshe.Ama-boilers avamile asebenzisa amalahle aye ahoxa kancane kancane esigabeni somlando, futhi amajeneretha amasha kagesi okushisa kagesi, amajeneretha ane-nitrogen ephansi kanye namajeneretha esitimu e-nitrogen aphansi kakhulu asephenduke amandla amakhulu embonini yokuphehla isitimu.
Ijeneretha yesitimu ene-nitrogen ephansi ibhekisela ejeneretha yesitimu enokukhishwa okuncane kwe-NOx ngesikhathi sokusha kukaphethiloli.Ukukhishwa kwe-NOx ye-generator yesitimu yegesi yemvelo yendabuko cishe ku-120 ~ 150mg/m3, kuyilapho ukukhishwa kwejeneretha yesitimu se-nitrogen ephansi cishe ku-30 ~
80mg/m2.Ukukhishwa kwe-NOx ngaphansi kuka-30mg/m3 ngokuvamile kubizwa ngokuthi amajeneretha omusi we-nitrogen we-nitrogen.
Eqinisweni, ukuguqulwa kwe-nitrogen ephansi kwe-boiler kuwubuchwepheshe bokubuyisela kabusha igesi ye-flue, okuwubuchwepheshe bokunciphisa i-ammonia oxide ngokubuyisela ingxenye yegesi ye-boiler flue esithandweni bese uyishisa ngegesi yemvelo nomoya.Ngokusebenzisa ubuchwepheshe be-flue gas recirculation, izinga lokushisa lomlilo endaweni ewumgogodla webhayela liyancishiswa futhi isilinganiso somoya oweqile sihlala singashintshile.Ngaphansi kwesimo sokuthi ukusebenza kahle kwe-boiler akuncishisiwe, ukukhiqizwa kwe-nitrogen oxides kucindezelwe, futhi inhloso yokunciphisa ukukhishwa kwe-nitrogen oxides ifinyelelwa.
Ukuze sihlole ukuthi ukukhishwa kwe-nitrogen oxide kweziphehlisi zesitimu ezine-nitrogen ephansi kungahlangabezana yini nezindinganiso zokungcoliswa komoya, senze ukuqapha ukungcola kumajeneretha esisi esine-nitrogen ephansi emakethe, futhi sathola ukuthi abakhiqizi abaningi bathengisa izinto ezijwayelekile zesitimu ngaphansi kwesiqubulo esithi. amajeneretha omusi ane-nitrogen ephansi, akhohlise abathengi ngamanani aphansi.
Kuyaqondakala ukuthi abakhiqizi abavamile be-nitrogen steam generator kanye nezimbawula bathunyelwa bevela phesheya, futhi izindleko zesishisi esisodwa ziphezulu kakhulu ngamashumi ezinkulungwane zamaRandi.Abathengi bayakhunjuzwa ukuthi bangalingwe ngamanani aphansi lapho bethenga!Ngaphezu kwalokho, hlola idatha yokukhishwa kwe-NOx .
