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 empendulweni yasekhaya “yokonga amandla kanye nokuncishiswa kokukhipha intuthu” futhi inciphise nakakhulu ukukhishwa kwe-nitrogen oxide kumajeneretha omusi, i-China ibheka ukubaluleka okukhulu ekuguqulweni kwe-nitrogen ephansi yamajeneretha esitimu futhi ibeke 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) Vala 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 eliyinhloko lokushisisa. Ngaphezu kwalokho, ingxenye yamalahle ahlutshiwe emoyeni ophakeme ingathunyelwa emzimbeni wesithando somlilo kusengaphambili (uma kuqhathaniswa nesikhundla esiphezulu sokuqala), ngoba Ukwehliswa kwesikhundla nakho kufana nokwelula isikhathi sokushiswa kwamalahle ahlutshiwe esithandweni somlilo. emoyeni ephakeme, okuyinzuzo ekunciphiseni okuqukethwe kwezinto ezivuthayo zomlotha wempukane kujeneretha lesitimu.
(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 yokushisisa ingathuthukisa ukungeneka kokugeleza kwamalahle okuputshuziwe komoya oyinhloko esithandweni futhi ikugcine 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. Ngaphezu kwalokho, umoya wesibili ubekwe ngendlela eqinile, ukuze umoya oyinhloko ugeleze ngokuphindaphindiwe ugijimele 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 izishisi 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.
