Ijeneretha ye-biomass encane ene-nitrogen ephansi Isithombe Esifakiwe

I-biomass steam generator encane ene-nitrogen ephansi

Incazelo emfushane:

Ijeneretha ye-steam encane yohlelo lobuchwepheshe lokuguqulwa kwe-nitrogen ephansi!

Ukuze iphendule impendulo yasekhaya "yokonga amandla kanye nokunciphisa ukukhishwa kwe-emission" futhi inciphise nakakhulu ukukhishwa kwe-nitrogen oxide okuqukethwe kwamajeneretha e-steam, i-China ibheka ukubaluleka okukhulu ekuguqulweni kwe-nitrogen ephansi yamajeneretha e-steam futhi ibeka phambili izinqubomgomo ezihambisanayo.Namuhla, ngizokwabelana nawe ngesixazululo sobuchwepheshe sokuguqulwa kwe-nitrogen ephansi yamajeneretha amancane we-steam:
1. Ukubuyisela kabusha izinga lekhwalithi yamalahle: ngokuvamile i-Var>18% evamile, i-Aar<35%.I-NOx emission concentration <300mg/m3.Uma izinga lamalahle liphansi, ukuhlaziya okuningiliziwe kuyadingeka.

2. Uhlelo oluqondile loguquko:
(1) Khulisa umoya wesibili.Ukuze kuzuzwe ukushiswa okujulile kanye nezigaba zomoya wesithando somlilo, isikhala esikhulu sokuvutha kanye nesikhala sokubuyisela sisele.Umbhobho womoya owodwa wesibili usethelwe emagumbini amane omzimba wesithando somlilo (ungakwazi ukushwibeka phezulu naphansi, futhi umoya wesibili ubekwe endaweni ephakeme ukuze kuqinisekiswe ukuphakama okwanele kokululama).I-air duct yesibili ifakwe umnyango oshelelayo.Imibhobho yomoya yesibili ifakwe izimpawu.Ukuguqulwa komoya wesibili kuyindlela eyinhloko yokulawula uhlobo lukaphethiloli kanye nohlobo olushisayo lwe-NOx.
(2) Cisha umoya wesithathu.Umbhobho womoya wezinga eliphezulu uvaliwe, kanti ipayipi lomoya lasekuqaleni lifakwe isihlukanisi.Ngemva kokudlula emoyeni ehlukaniswe wugqinsi futhi mncane, uhlangothi oluwugqinsi lungena emoyeni wesibili ongenhla, futhi uhlangothi olukhanyayo lusetshenziswa njengomoya wesibili.Ukuletha umoya wezinga eliphezulu emoyeni wesibili kunganciphisa umthamo womoya wesibili webanga lokuqala lokushisisa eliyinhloko.Ngaphezu kwalokho, ingxenye yamalahle acwebile emoyeni ephakeme ingathunyelwa emzimbeni wesithando somlilo kusengaphambili (uma kuqhathaniswa nesikhundla esiphezulu sokuqala), ngoba Ukwehliswa kwesikhundla nakho kufana nokwelula isikhathi sokushiswa kwamalahle acibilikile esithandweni. emoyeni ophakeme, okuzuzisa ukunciphisa okuqukethwe kwezinto ezivuthayo zomlotha we-fly ku-generator yesitimu.
(3) Ukuguqulwa kombhobho womoya wesibili.Ngokohlelo oluqondile lokuguqulwa kwesiyingi sesibili sokugunda umoya esithandweni somlilo, njengoba kuboniswe kuMfanekiso 1, izindawo ezintathu ezinezici zensimu ezihluke ngokuphelele kanye nokusatshalaliswa kwendawo eseduze nodonga zakhiwe engxenyeni yomzimba wesithando somlilo.Ingaqinisekisa ukuthi kunomoya-mpilo owanele odongeni ukuze kugwenywe ukugqwala kwe-slagging kanye nezinga lokushisa eliphezulu ngaphandle kokushintsha isiqondiso sendiza enkulu.

Le ndlela yokushiswa ingathuthukisa ukungeneka kokugeleza kwamalahle okucindezelwe komoya okuyinhloko esithandweni futhi iwugcine kude nodonga lwamanzi ngezansi, inciphise ukugqwala, ukugqwala kwezinga lokushisa eliphezulu kanye nokufakwa komlotha esithandweni.Ukwengeza, ngenxa yokuthi isiqondiso sendilinga ye-tangent eyinhloko neyesibili iphambene, isixhumanisi sokuxuba amalahle agxotshiwe nomoya siyabambezeleka, ngaleyo ndlela kunciphisa ukukhishwa kwe-NOx.Ukwengeza, umoya wesibili ubekwe ngendlela eqinile, ukuze ukugeleza komoya okuyinhloko kugijimele emoyeni oshisa kakhulu ovela phezulu, ukuze amalahle ahlutshiwe agxilwe ngokuvilapha kule ndawo.Ngaphansi kwesimo sokuntuleka kwe-oxygen, indaba eguquguqukayo iyancipha ngokushesha ngangokunokwenzeka futhi ivutha futhi ishise, okubaluleke kakhulu ekushiseni okuzinzile nokuvutha.Kukhona izinzuzo.
(4) Ukuguqulwa kokuvutha kwamafutha amancane.Kumajeneretha amancane we-steam, shintsha izimbawula ezi-2 kungqimba engezansi ye-generator yesitimu sokuqala ngezishisi eziphansi ze-NOX ezinomsebenzi wokuthungela uwoyela omncane.Umshini ungenza ilahle eligayiwe livuthe futhi lishise ngokushesha.Ngemuva kokuguqulwa, akudingekile ukusebenzisa isibhamu esikhulu samafutha lapho i-generator ye-steam isebenza, egcina uphethiloli omningi wesitshalo samandla.
