i-boiler yegesi ye-nitrogen ephansi

Incazelo emfushane:

Ungahlukanisa kanjani ukuthi ijeneretha yesitimu iyijeneretha ye-nitrogen ephansi
I-steam generator ingumkhiqizo ohambisana nemvelo ongakhiphi igesi engcolile, izinsalela zemfucuza kanye namanzi angcolile ngesikhathi sokusebenza, futhi ubizwa nangokuthi i-boiler enobungani bemvelo. Noma kunjalo, ama-nitrogen oxide asazokhishwa ngesikhathi sokusebenza kwamajeneretha amakhulu aphuma ngegesi. Ukuze kuncishiswe ukungcoliswa kwezimboni, umbuso umemezele izinkomba eziqinile zokukhishwa kwe-nitrogen oxide futhi wacela yonke imikhakha yomphakathi ukuthi imiselele amabhayela angayingeni imvelo.
Ngakolunye uhlangothi, izinqubomgomo eziqinile zokuvikela imvelo nazo zikhuthaze abakhiqizi abakhiqiza umusi ukuthi baqhubeke nokusungula izinto ezintsha kwezobuchwepheshe. Ama-boilers wamalahle endabuko ahoxile kancane kancane esigabeni somlando. Amajeneretha amasha kagesi wokushisisa isitimu, amajeneretha ane-nitrogen aphansi, kanye namajeneretha ane-nitrogen ephansi kakhulu, Iba amandla amakhulu embonini yokuphehla isitimu.
Amajeneretha omusi ane-nitrogen ephansi abhekisela kumajeneretha esitimu anokukhishwa okuncane kwe-NOx ngesikhathi sokushiswa kukaphethiloli. Ukukhishwa kwe-NOx kwejeneretha yesitimu yegesi yemvelo evamile cishe ku-120~150mg/m3, kuyilapho ukukhishwa okujwayelekile kwe-NOx kwejeneretha yesitimu se-nitrogen ephansi cishe ku-30~80 mg/m2. Labo abanokukhishwa kwe-NOx ngaphansi kuka-30 mg/m3 ngokuvamile babizwa ngokuthi amajeneretha e-nitrogen steam aphansi kakhulu.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Eqinisweni, uguquko lwe-boiler low-nitrogen ubuchwepheshe bokubuyisela kabusha igesi ye-flue, okuwubuchwepheshe bokunciphisa ama-nitrogen oxide ngokubuyisela ingxenye yentuthu yokukhipha ibhayela esithandweni bese ixutshwa negesi yemvelo nomoya ukuze kushiswe. Ngokusebenzisa ubuchwepheshe be-flue gas recirculation, izinga lokushisa lomlilo endaweni ewumgogodla webhayela liyancipha, futhi i-coefficient yomoya eyeqile ihlala ingashintshile. Ukwakhiwa kwama-nitrogen oxides kucindezelwa ngaphandle kokunciphisa ukusebenza kahle kwebhayela, futhi inhloso yokunciphisa ukukhishwa kwe-nitrogen oxide iyafinyelelwa.
Ukuze kuhlolwe ukuthi ingabe ukukhishwa kwe-nitrogen oxide kweziphehlisi zesitimu ezine-nitrogen ephansi kungahlangabezana nezindinganiso zokungcoliswa komoya, senze ukuqapha kokukhipha isitimu esine-nitrogen ephansi emakethe, futhi sathola ukuthi abakhiqizi abaningi basebenzisa isiqubulo samajeneretha esitimu ane-nitrogen ephansi ukuze bakhohlise ngamanani aphansi Abathengi empeleni bathengisa izisetshenziswa ezijwayelekile zesitimu.
Kuyaqondakala ukuthi kubakhiqizi abajwayelekile be-nitrogen steam generator abavamile, izimbawula zingeniswa zivela phesheya, futhi izindleko zokushisa okukodwa zingamashumi ezinkulungwane zama-yuan. Abathengi bayakhunjuzwa ukuthi bangalingwe ngamanani aphansi lapho bethenga! Ngaphezu kwalokho, hlola idatha yokukhishwa kwe-nitrogen oxide.
