Ijeneretha yesitimu, evame ukubizwa ngokuthi i-steam boiler, iyisisetshenziswa esiwumshini esebenzisa amandla ashisayo kaphethiloli noma amanye amandla ukushisisa amanzi abe emanzini ashisayo noma isitimu.Amajeneretha esitimu angahlukaniswa abe amajeneretha kagesi ashisisa isitimu, amajeneretha omusi kaphethiloli, kanye namajeneretha esitimu segesi ngokuya ngezigaba zikaphethiloli.
Ngesikhathi sokusetshenziswa kwejeneretha yesitimu, ukushiswa kukaphethiloli kuzokhipha ama-nitrogen oxide, ayingozi kakhulu emvelweni.Ngakolunye uhlangothi, ama-nitrogen oxides azosabela ne-ozone futhi acekele phansi ungqimba lwe-ozone (i-ozone ingahlanza amanzi nomoya, ikhiphe amagciwane futhi ibulale amagciwane, futhi imunce ukukhanya kwelanga. Imisebe eyingozi emzimbeni womuntu ekukhanyeni, njll.).
Ngakolunye uhlangothi, lapho amanitrogen oxide ehlangana nomhwamuko wamanzi emoyeni, ayokwakha amaconsi esulfuric acid nenitric acid, okuzokwenza amanzi emvula abe neasidi futhi akhe imvula eneacid, engcolisa indawo ezungezile.Lapho igesi ihogelwa abantu, izophenduka ibe yi-sulfuric acid futhi idle izitho zokuphefumula zomuntu.Into esabekayo kakhulu igesi ye-nitrogen oxide, umzimba wethu womuntu ongawuzwa nhlobo.Singakwazi kuphela “ukwamukela” amagesi e-nitrogen oxide angezwakali emzimbeni.
Ngakho-ke, ngokuhambisana nezidingo zokuvikelwa kwemvelo kazwelonke, ohulumeni basekhaya baye baqala ukuguqulwa kwe-nitrogen ephansi yama-boilers.Ukunciphisa ukukhishwa kwe-nitrogen oxide kuyinkinga eyinhloko abakhiqizi be-steam generator okufanele bayixazulule lapho bethuthukisa imikhiqizo yabo.
Njengebhizinisi kazwelonke lobuchwepheshe obuphezulu, uNobeth usebenzise imali eningi namandla ocwaningweni lwemikhiqizo nokuthuthukiswa kanye nokuthuthukiswa kobuchwepheshe.Eminyakeni engu-20 edlule, umkhiqizo ubuyekezwe ngokuphindaphindiwe izikhathi ezimbalwa.Ijeneretha yesitimu sohlobo lukawoyela-yegesi ekhiqizwe manje ngaphandle kokufaka isebenzisa ubuchwepheshe bokushiswa kwe-nitrogen ephansi kakhulu, ekhipha initrogen engaphansi kuka-10㎎/m³.Isebenzisa izenzo ezingokoqobo ukuze kusetshenziswe "ukungathathi hlangothi kwekhabhoni".Umgomo wamasu “wokufinyelela inani eliphakeme lokukhishwa kwekhabhoni” uqashelwe iningi labasebenzisi, futhi wenze igxathu elisezingeni eliphezulu mayelana nokusebenziseka kalula kanye nomthelela wokonga amandla.
I-Nobeth diaphragm wall steam generator ikhetha izimbawula ezingeniswa kwamanye amazwe futhi isebenzisa ubuchwepheshe obuthuthukisiwe obufana nokujikeleza kwegesi ephumayo, ukuhlukaniswa, nokuhlukaniswa kwelangabi ukuze kuncishiswe kakhulu ukukhishwa kwe-nitrogen oxide futhi kufinyelele futhi ngaphansi kakhulu “kokukhishwa kwe-ultra-low” okudingwa yimithetho kazwelonke.“(30㎎/m³) okujwayelekile.Futhi isekela amasistimu omthombo wokushisa aluhlaza futhi avumela imvelo, okuhlanganisa igesi, i-nitrogen ephansi kakhulu, uwoyela negesi exutshwe, kanye ne-biogas.I-Nobeth ihlanganyela nabasebenzisi ngobuchwepheshe bayo obuhamba phambili be-steam ukusiza ukuvikelwa kwemvelo.
