eyodwa,Iyini i-boiler ye-nitrogen ephansi?

Amabhoyili ane-nitrogen ephansi ngokuvamile abhekisela kumabhayela abaselwa igesi anokukhishwa kwe-nitrogen oxide ngaphansi kuka-80mg/m3.

• Ukusebenza kahle okuphezulu kakhulu (kufika ku-108%);
• Ukukhishwa okuphansi kakhulu kwezinto eziyingozi (i-NOX ingaphansi kuka-8ppm/18mg/m3);
• Izinyathelo eziphansi kakhulu (1.6m2/tonnage);
• Ukulawula okuhlakaniphile kakhulu (isilawuli se-Siemens);
• Izinga lokushisa eliphansi kakhulu legesi yokukhipha umoya (eliphansi njenge-35℃);
• Ukusebenza okuthule kakhulu (45 dB);
• Ukuvikelwa kokuphepha okuphezulu (izendlalelo eziyi-11 zokuvikela);
• ukubukeka okuhle kakhulu (ukubukeka okumhlophe okupholile);
• Iphaneli yokulawula esebenziseka kalula (i-LCD);
• Impilo ende yenkonzo (iminyaka engama-40);
• Umfutho wegesi ophansi kakhulu (1.7~2.1kpa);
• Ibanga lokulungiswa kwesilinganiso esiphezulu kakhulu: 1:7 (15~100%);
• Isondo elithwala umthwalo eliphelele (kulula ukulihambisa nokulilungisa).

ezimbili,Asebenza kanjani ama-boilers e-nitrogen aphansi

Ama-boilers ane-nitrogen ephansi athuthukiswa ngesisekelo sama-boilers ajwayelekile. Uma kuqhathaniswa nama-boilers wendabuko, ama-boilers ane-nitrogen ephansi ikakhulukazi asebenzisa ubuchwepheshe obuhlukahlukene bokulawula amandla okushisa ukuze kuncishiswe izinga lokushisa elivuthayo, ngaleyo ndlela ehlise ukukhishwa kwe-NOx, futhi afinyelele kalula ukukhishwa kwe-NOx ngaphansi kuka-80mg/m3, Ngisho nokukhishwa kwebhayela le-nitrogen okuphansi kwe-NOx kungaba ngaphansi kuka-30mg. /m3.

Ubuchwepheshe bokushiswa kwe-nitrogen ephansi bulawula ikakhulukazi izinga lokushisa lokushisa futhi bunciphise ukukhiqizwa kwama-nitrogen oxides ashisayo.

ezintathu,Yiziphi izinhlobo zama-boilers ane-nitrogen aphansi akhona?

1、I-flue gas recirculation low nitrogen boiler

Ibhayela ye-flue gas recirculation low-nitrogen iyinhloko yokucindezela esebenzisa umoya osekela ukuvutha ukuncela ingxenye yegesi evuthayo ibuyele esitokisini, lapho ixutshwa khona nomoya ukuze ivuthe. Ngenxa yokuguqulwa kabusha kwegesi ye-flue, amandla okushisa egesi e-flue evuthayo makhulu, ukuze izinga lokushisa lomlilo lilawulwe kuma-degree angu-1000, ngaleyo ndlela kunciphisa ukwakheka kwe-nitrogen oxides.

2、I-boiler ye-nitrogen ephansi exutshwe ngokuphelele

Ibhayela ye-nitrogen ephansi exutshwe ngokuphelele yamukela ubuchwepheshe obuxubene ngokugcwele, obungakwazi ukuzuza isilinganiso esihle sokuxuba ngokulungisa igesi nomoya ovuthayo, futhi kuzuze ukuvutha okuphelele kukaphethiloli. Futhi i-low-nitrogen boiler burner ingakha ingxube yegesi exutshwe ngokufanayo ngaphambi kokuba igesi nomoya osekela ukuvutha ungene esithandweni, bese ushisa ngokuqinile, unciphisa ukukhishwa kwe-nitrogen oxides.

Izinzuzo: ukudluliswa kokushisa kwe-radiator efanayo, ukudluliswa kokushisa okuthuthukisiwe; ijubane elilungile lokuvutha, izinga lokushisa nokuphepha; indawo ekhulisa imisebe; ukuqina kwemisebe yeyunithi eguquguqukayo; Ukutholwa kokushisa okucashile kwe-vaporization.

Okune,Ukulungiswa kabusha kweBoiler Ye-nitrogen Ephansi

01)I-Boiler Ephansi Ye-nitrogen Retrofit

>

I-boiler low-nitrogen transformation ubuchwepheshe bokubuyisela kabusha igesi e-flue, okuwubuchwepheshe bokunciphisa ama-nitrogen oxide ngokubuyisela ingxenye yentuthu ekhipha ibhoyela esithandweni bese ixutshwa negesi yemvelo nomoya ukuze kushiswe. Ukusebenzisa ubuchwepheshe be-flue gas recirculation, izinga lokushisa lomlilo endaweni eyinhloko ye-boiler liyancipha, futhi i-coefficient yomoya eyeqile ihlala ingashintshi. Ngaphansi kwesimo sokuthi ukusebenza kahle kwe-boiler akuncishisiwe, ukwakheka kwe-nitrogen oxides kuvinjelwe, futhi inhloso yokunciphisa ukukhishwa kwe-nitrogen oxide ifinyelelwa.

Ukuze kuqinisekiswe ukushiswa okuphelele kukaphethiloli, ngokuvamile kudingekile ukunikeza ingxenye ethile yomoya owedlulele ngaphezu komthamo womoya wethiyori odingekayo ekushiseni. Ngokwesisekelo sokuqinisekisa ukusebenza kahle kokushisa kokuvutha, i-coefficient encane yomoya eyeqile ikhethwa ukuze kuncishiswe ukugcwala komoyampilo kugesi we-flue. , izokwazi ukuvimbela ngempumelelo ukwakheka kwe-NOx.

Eqinisweni, ukuguqulwa kwe-nitrogen ephansi kwama-boilers ubuchwepheshe be-flue gas recirculation, okuwubuchwepheshe bokunciphisa i-nitrogen oxides ngokubuyisela ingxenye yentuthu yokukhipha ibhayela esithandweni bese uyixuba negesi yemvelo kanye nomoya ukuze kushiswe. Ukusebenzisa ubuchwepheshe be-flue gas recirculation, izinga lokushisa lomlilo endaweni eyinhloko ye-boiler liyancipha, futhi i-coefficient yomoya eyeqile ihlala ingashintshi. Ngaphansi kwesimo sokuthi ukusebenza kahle kwe-boiler akuncishisiwe, ukwakheka kwe-nitrogen oxides kucindezelwe, futhi inhloso yokunciphisa ukukhishwa kwe-nitrogen oxide ifinyelelwa.

Lapho i-boiler isebenza ngomthwalo ophezulu, umthamo womoya we-blower ngokuvamile ukhuphuka ukwandisa izinga lokushisa lomlilo. Ngalesi sikhathi, i-coefficient yomoya eyeqile ivame ukuba nkulu, izinga lokushisa lomlilo liphezulu, futhi inani le-NOx elakhiwe likhulu. I-boiler ephansi ye-nitrogen isebenza kahle ngaphansi kwezimo eziphakeme zomthwalo, futhi ngesikhathi esifanayo ilawula izinga lokushisa lesithando somlilo, elingacindezela ngokuphumelelayo ukukhiqizwa kwe-NOx.

I-NOx nitrogen oxides ikhiqizwa ngenxa ye-oxidation ye-N2 emoyeni ovuthayo ngaphansi kwesenzo sokushisa okuphezulu. Ukuguqulwa kwe-nitrogen ephansi kungalawula ngempumelelo izinga lokushisa elingaphansi kuka-1000 degrees. ukugxila kuyancipha kakhulu.

02）I-Low-nitrogen Retrofit ye-Gas Boiler

1）Ukulungiswa kwe-boiler main body

Ukuze uthole ukuguqulwa kwe-nitrogen ephansi yezithando zomlilo zendabuko ezinkulu zendabuko, ngokuvamile kuyadingeka ukuguqula isithando somlilo nendawo yokushisa, ukuze i-gas boiler ishise ngokugcwele, futhi okuqukethwe kwe-nitrogen oxide kugesi we-flue kuyancipha, futhi ekugcineni. inhloso yokuguqulwa kwegesi ye-nitrogen ephansi ifinyelelwe.

2）I-Burner Retrofit

Ngokuvamile, indlela ephansi ye-nitrogen retrofit yamabhayela wegesi i-burner retrofit. Sikhetha ukufaka isishisi esine-nitrogen ephansi ukuze senze isishisi songe amandla kakhudlwana, sivumelane nemvelo futhi sisebenze kahle, ngaleyo ndlela sinciphise okuqukethwe kwama-ammonia oxides kubhayela. Izishisi ezine-nitrogen ephansi zihlukaniswa zibe yi-nitrogen evamile kanye ne-ultra-low. Okuqukethwe kwe-NOx kwezishisi ezijwayelekile kuphakathi kuka-80mg/m3 no-150mg/m3, kuyilapho okuqukethwe kwe-NOx kwezishisi ze-NOx eziphansi kakhulu kungaphansi kuka-30mg/m3.

Ukuguqulwa kwe-ammonia ephansi yama-boilers aphethwe yigesi kwenziwa ikakhulukazi ngezindlela ezimbili ezingenhla. I-Burner low nitrogen retrofit, ngokuvamile ifanele ama-boilers amancane wegesi. Uma i-boiler yegesi enkulu kufanele ifakwe kabusha nge-nitrogen ephansi, isithando somlilo kanye nomshini wokushisa kufanele kwenziwe ngesikhathi esifanayo, ukuze i-boiler eyinhloko kanye nomshini wokushisa kuhlanganiswe futhi kusetshenziswe ngokuphumelelayo.
