Incazelo emfushane:

I-nitrogen oxide kugesi ephumayo yesethi yejeneretha yenjini yasolwandle iyigesi eyakhiwe ukucwiliswa kwe-nitrogen kusilinda ezingeni lokushisa eliphezulu, elakhiwe ikakhulukazi i-nitric oxide ne-nitrogen dioxide.Ukuvikelwa kwemvelo kweGreen Valley kusungule isethi yesistimu yokukhishwa kwe-"grvnes" ye-SCR yokwelapha ama-nitrogen oxides egesini elilahlwa amajeneretha asolwandle ngemva kweminyaka eminingi yocwaningo olunzima.Ngemuva kokuklama okukhethekile, uhlelo lusakwazi ukubona ukusebenza kahle okuphezulu ngaphansi kwesimo sokushisa okungazinzile kokukhipha kanye nekhwalithi yegesi;Izingxenye ezibalulekile zingamelana nokungcola okuvamile kwegesi yokulahla imfucumfucu futhi ziqinisekise ukusebenza okuzinzile kwesikhathi eside kwesistimu.

Isingeniso sobuchwepheshe

Ukuvikelwa kwemvelo kwe-Grvnes kusungule isethi ye-"grvnes" ye-SCR denitration system yokwelapha ama-nitrogen oxides egesini elilahlwa amajeneretha asolwandle ngemva kweminyaka eminingi yocwaningo olunzima.Ngemuva kokuklama okukhethekile, uhlelo lusakwazi ukubona ukusebenza kahle okuphezulu ngaphansi kwesimo sokushisa okungazinzile kokukhipha kanye nekhwalithi yegesi;Izingxenye ezibalulekile zingamelana nokungcola okuvamile kwegesi yokulahla imfucumfucu futhi ziqinisekise ukusebenza okuzinzile kwesikhathi eside kwesistimu.

Ukuvikelwa kwemvelo kwe-Grvnes kusungule isethi ye-"grvnes" SCR denitration system yokwelapha ama-nitrogen oxide ekuphehleni kwamandla egesi yokulahla udoti ngemva kweminyaka yocwaningo olunzima.

Izinzuzo zobuchwepheshe

1. Isivinini sokuphendula esisheshayo.

2. Ingasetshenziswa ekuhlukaniseni emazingeni okushisa aphansi, aphakathi nendawo naphezulu.

3. Ubuchwepheshe obuvuthiwe nobunokwethenjelwa, ukusebenza kahle kwe-denitration ephezulu kanye nokunciphisa ukuphunyuka kwe-ammonia.

4. Umjovo we-ammonia olinganayo, ukumelana okuphansi, ukusetshenziswa kwe-ammonia okuphansi kanye nezindleko zokusebenza eziphansi.

Ulwazi lobuchwepheshe

"Ukuzulazula okuphephile, ulwandle oluhlanzekile kanye nokuzulazula okulula" kuyinjongo yokusebenza nomgomo we-International Maritime Organization kanye neziphathimandla zezasolwandle ezinekhono emhlabeni wonke.

Ezinjinini zikadizili zasolwandle, ukukhishwa kwesisi esiyingozi kwezinjini zikadizili ikakhulukazi.I-NOx (lapho inombolo engu-95%), i-Sox (lapho i-S02 ingu-95% futhi i-S03 ingu-5%), i-HC, i-CH2, i-Co, i-C02 namanye amagesi kanye nokukhishwa kwezinhlayiya (PM) kubangela amazinga ahlukene omonakalo endaweni ezungezile.Kuyabonakala ukuthi ukukhishwa kwe-exhaust ye-rudder diesel kungenye yezinto ezibalulekile ezithinta izinga lomoya womhlaba kanye nemvelo, ukuze kuvikelwe indawo ezungezile yomhlaba esihlala kuwo.

I-Grvnestech ithuthukise okokusebenza kokulawula intuthu emnyama kanye nemishini yokulawula i-nitrogen oxide yokunciphisa nokulawula ukungcoliswa komoya okubangelwa iphini lomkhumbi.

Izindlela zokunciphisa i-particle (PM) kanye ne-nitrogen oxides (NOx) kuxoxwa ngayo ngezansi kakhulu:

 

Izindlela zokunciphisa i-particle (PM):

Igesi yemfucuza elashwa nge-particle trap (DPF) eyakhiwe inkampani ye-grvnes ingafinyelela izinga le-lingman blackness level I nangaphansi.

Izindlela zokunciphisa i-nitrogen oxide (NOx):

I-SCR denitration system eyakhiwe inkampani ye-grvnes ingahlangabezana nezindinganiso ezifanele.Isistimu yokukhipha imfucuza ye-Grvnes-scr ingenza ngokwezifiso isikimu sokwelashwa kwegesi eyimfucuza eyodwa kuye kwelinye ngokuya ngezinga lokushisa elihlukile lokukhipha imfucuza kanye nokwakheka kwegesi eyimfucuza.
