I-260tph CFB boiler ifaka amabanga abanzi okulayisha kanye nokuguquguquka kwamafutha aqinile. Izinga lokushisa lomlilo lingu-850-900 ℃, lihlome ngomoya wokuqala kanye nomoya wesibili, onganciphisa kakhulu ukuphuma kwe-nox. Inkampani eyodwa eshisayo yakha ama-boilers amathathu we-260tph CFB nama-boilers amabili we-130t / h / h / h / h CFB boilers, kanye nomthamo wokuhlinzeka nge-Steam / h.

Ukuhlaziywa kokwakheka kwamalahle

Isithando somlilo samukela isakhiwo esigcwele sodonga lwe-membrane esimisiwe. Izingcezu ezine zezikrini zemisila ebabazekayo nezingcezu ezinhlanu zezikrini zokuhwamuka zamanzi zisesithandweni somlilo. Abahlukanisi ababili bokushisa okushisa kakhulu baphakathi kwesithando somlilo kanye nomsila we-flue duct, futhi i-SNCR isendaweni ye-upkati. Isihlukanisi ngasinye se-cyclone sine-Return Reter. I-High Temperature Supertheater, i-supertheater ephansi yokushisa, i-Economizer ne-Air Presem kusemsikeni we-flue due. I-Economizer yamukela ukuhlelwa okumisiwe kwamashubhu angenalutho nge-scr phakathi.

I-Ultra-Low Ngakho₂ ukuphuma kwe-260tph CFB Boiler

Ama-boilers we-CFB avame ukwamukela izinto zokuphelelwa yisikhathi sokuhlanza impahla kanye nomsila omile wemishini yokuhlanza imisila. Ekugcineni, sinquma ukusetha imishini eyodwa kuphela e-wawfulfurization endaweni ephumayo ye-Dust Collector. Ukusebenza kwangempela kukhombisa ukuthi lapho kunjalo₂Ukugxila kugesi ye-flue efaka i-deselfurization tower kuyinto engu-1500mg / m³, Kanjalo₂ukuphuma kungu-15mg / m³.

Ukudilizwa okusebenzayo kwe-260tph CFB Boiler

Kusukela ngo-2016 kuya ku-2018, abacwaningi bethu bavakashela ama-130 ~ 220t / h CFB boilers ekusebenzeni, futhi bahlolwe insimu. I-Nox Emission ihambelana kakhulu nohlobo lwamalahle, izinga lokushisa elisebenzayo, okuhlanganisiwe komoya okweqile, okuhlukaniswe ngomoya kanye nokusebenza kwe-cyclone.

Uhlobo lwamalahle: okuqukethwe okuphezulu kwe-nitrogen ku-mafutha kuzoholela ekukhiqizweni okuphezulu kwe-NOX ekuvukeni. Amalahle anezinto eziguquguqukayo eziphakeme, ezinjenge-lignite, kuzoholela ekukhishweni okuphezulu kwe-nox.

Izinga lokushisa le-Traceace lokushisa lomlilo Kunengqondo ukulawula izinga lokushisa lomlilo ku-880 ~ 890 ℃.

I-coefficient yomoya eyeqile: umoya-mpilo omncane esithandweni somlilo, kukhiqizwa okuncane kwe-NOX. Kodwa-ke, ukuncishiswa ngokweqile komoya-mpilo kuzoholela ekwandeni kokuqukethwe kwekhabhoni ku-Fly Ash kanye ne-CO, okuzoholela ekunciphiseni ukusebenza kahle. Lapho okuqukethwe komoya-mpilo esithweni seFurace kungu-2% ~ 3%, isizukulwane se-nox sincane, futhi ukusebenza kahle kokuhlangana kuphezulu.

Ukuhlinzekwa komoya okuhlukaniswe: Cishe ngo-50% womoya ungena isithando somlilo engxenyeni engezansi yesithando somlilo. Njengoba ingxenye engezansi isesimweni esincishisiwe, i-NOX ibuyelwe ku-N2 ne-O2, evimbela isizukulwane se-nox. Phumula umoya we-50% wokuhlanganisa usuka engxenyeni engenhla yegumbi lokuhlanganisa.

Design Criterion of 260tph CFB boiler ukwehlisa ukuphuma kwe-nox

1. Lawula izinga lokushisa lokuvutha ngo-880 ~ 890 ℃ ngesithando somlilo sokufudumeza somlilo.

2 Ukuphumula okungu-55% komoya kungena engxenyeni ephezulu njengendiza yesibili.

3. I-inlet yomoya wesibili izokhushulwa ukuze iqinisekise ukuthi ingxenye engezansi iyindawo eqinile yokunciphisa.

4. Thola ivolumu yomoya ephelele esekelwe kokuqukethwe komoya-mpilo kwe-2% ~ 3% kugesi ye-flue.

I-5 Isakhiwo se-Inlet esilungiselelwe sandisa isilinganiso sezinhlayiya ezinhle futhi senza izinga lokushisa legesi elingenamkhawulo.
