Mbini,Zisebenza kangakanani iibhoyila zenitrogen

Iibhoyili ze-nitrogen eziphantsi ziphuculwa ngesiseko se-boilers eziqhelekileyo. Xa kuthelekiswa neebhoyila zemveli, iibhoyila ezisezantsi-nitrogen ikakhulu zisebenzisa ubugcisa ezahlukeneyo zolawulo lokutshiswa ukunciphisa ubushushu, ngaloo ndlela ukunciphisa NOx ukukhutshwa, kwaye ngokulula ukufikelela NOx ukukhutshwa ngaphantsi kwe 80mg/m3, Nokuba ezinye nitrogen kwibhoyila ephantsi Ukukhutshwa kweNOx kunokuba ngaphantsi kwe-30mg. /m3.

Ubuchwephesha bokutsha benitrogen obuphantsi bulawula ikakhulu ubushushu bokutsha kwaye bunciphisa ukuveliswa kweeoksidi zenitrogen ezishushu.

Ntathu,Zeziphi iintlobo zeebhoyila ezinenitrogen ephantsi ezikhoyo?

1、Ibhoyila yenitrogen ephantsi

Ibhoyila yegesi ye-flue ephantsi kwe-nitrogen yintloko yoxinzelelo esebenzisa umoya oxhasa ukutsha ukuze ifunxe inxalenye yegesi yokutshisa i-flue ibuyele kwisitshisi, apho ixutywe nomoya wokutsha. Ngenxa yokujikeleza kwakhona kwegesi ye-flue, amandla okushisa egesi yokutshisa igesi enkulu, ukwenzela ukuba ukushisa okutsha kulawuleke kwii-degrees ze-1000, ngaloo ndlela kuncitshiswe ukubunjwa kwe-nitrogen oxides.

2、Ibhoyila enenitrogen exutywe ngokupheleleyo

Ibhoyili ephantsi kwe-nitrogen exutywe ngokupheleleyo ithatha itekhnoloji exutywe ngokupheleleyo, enokufikelela kumlinganiselo ofanelekileyo wokuxuba ngokulungelelanisa igesi kunye nomoya wokutsha, kunye nokufezekisa ukutsha okupheleleyo kwamafutha. Kwaye isitshisi sebhoyila esisezantsi-nitrogen sinokwenza umxube wegesi odibeneyo phambi kokuba igesi kunye nomoya oxhasa ukutsha ungene eziko, uze utshise ngokuzinzileyo, ukunciphisa ukukhutshwa kwenitrogen oxides.

Izinto eziluncedo: ukuhanjiswa kobushushu obufanayo kwiradiyetha, ukugqithiswa kobushushu obuphuculweyo; esona santya siphezulu sokutsha, ubushushu kunye nokhuseleko; ukwanda kwendawo yokusasazeka kwemitha; ukuqina kweyunithi yemitha; Ukubuyiswa kobushushu obufihlakeleyo bomphunga.

Isine,Ukubuyisela kwakhona kwiBoiler yeNitrojeni ephantsi

01I-Boiler ephantsi ye-Nitrogen Retrofit

>

Ukuguqulwa kwe-boiler ephantsi kwe-nitrogen yi-teknoloji ye-flue gas recirculation, eyiteknoloji yokunciphisa i-nitrogen oxides ngokubuyisela inxalenye yebhoyila yokukhupha umsi eziko kwaye ixutywe negesi yendalo kunye nomoya wokutsha. Ukusebenzisa iteknoloji yokubuyisela igesi ye-flue, ukushisa okutsha kwindawo engundoqo yebhoyili kuyancipha, kwaye i-coefficient yomoya engaphezulu ihlala ingatshintshi. Ngaphantsi kwemeko yokuba ukusebenza kwebhoyili kungancitshiswa, ukubunjwa kwe-nitrogen oxides kuvinjelwe, kwaye injongo yokunciphisa ukukhutshwa kwe-nitrogen oxide ifezekisiwe.

Ukuze kuqinisekiswe ukutshiswa okupheleleyo kwepetroli, ngokuqhelekileyo kuyimfuneko ukubonelela umlinganiselo othile womoya ogqithiseleyo ngaphezu komthamo womoya wethiyori ofunekayo ekutshiseni. Kwisiseko sokuqinisekisa ukusebenza kakuhle kwe-thermal yokutsha, i-coefficient encinci yomoya ogqithisiweyo ikhethiweyo ukunciphisa i-oxygen concentration kwi-flue gas. , iya kukwazi ukuthintela ngokufanelekileyo ukubunjwa kwe-NOx.

Enyanisweni, ukuguqulwa kwe-nitrogen ephantsi kweebhoyili yi-teknoloji ye-flue gas recirculation, eyi-teknoloji yokunciphisa i-nitrogen oxides ngokubuyisela inxalenye yebhoyili yokukhupha umsi eziko kwaye ixutywe kunye negesi yendalo kunye nomoya wokutsha. Ukusebenzisa iteknoloji yokubuyisela igesi ye-flue, ukushisa okutsha kwindawo engundoqo yebhoyili kuyancipha, kwaye i-coefficient yomoya engaphezulu ihlala ingatshintshi. Ngaphantsi kwemeko yokuba ukusebenza kwebhoyili kungancitshiswa, ukubunjwa kwe-nitrogen oxides kucinezelwe, kwaye injongo yokunciphisa ukukhutshwa kwe-nitrogen oxide ifezekisiwe.

Xa ibhoyili isebenza kumthwalo ophezulu, umthamo womoya we-blower udla ngokunyuka ukwandisa ukushisa kwesithando somlilo. Ngeli xesha, i-coefficient yomoya engaphezulu idla ngokuba nkulu, ukushisa kwesithando somlilo kuphezulu, kwaye inani le-NOx eliveliswe likhulu. Ibhoyili ephantsi-nitrogen isebenza kakuhle phantsi kweemeko eziphezulu zomthwalo, kwaye ngexesha elifanayo lilawula ukushisa kwesithando somlilo, esinokucinezela ngokufanelekileyo isizukulwana se-NOx.

I-NOx i-nitrogen oxides yenziwa ngenxa ye-oxidation ye-N2 emoyeni ovuthayo phantsi kwesenzo sokushisa okuphezulu. Ukuguqulwa kwe-nitrogen ephantsi kunokulawula ngokufanelekileyo ubushushu bokutsha obungaphantsi kwe-1000 degrees. Ugxininiso luyancipha kakhulu.

02）I-nitrogen ephantsi ye-Retrofit yeBoiler yegesi

1）Ukulungiswa kwe-boiler engundoqo yomzimba

Kuba inguqu ephantsi-nitrogen jikelele ezinkulu-isikali ezinkulu eziko zentsimbi zemveli, ngokuqhelekileyo kuyimfuneko ukuguqula eziko kunye nendawo zokufudumeza, ukuze kwibhoyila igesi uvutha ngakumbi, kunye nitrogen oxide umxholo kwigesi flue kuncitshiswe ngakumbi, yaye ekugqibeleni. injongo yokuguqulwa kwegesi ye-nitrogen ephantsi ifezekisiwe.

2）Burner Retrofit

Ngokuqhelekileyo, indlela ye-nitrogen ephantsi ye-retrofit yeebhoyila zegesi yi-burner retrofit. Sikhetha ukutshintsha i-low-nitrogen burner ukwenza isitshisi sigcine amandla ngakumbi, sikhuseleke ngokusingqongileyo kwaye sisebenze kakuhle, ngaloo ndlela sinciphisa umxholo we-ammonia oxides kwibhoyila yokukhupha. Izitshisi ze-nitrogen eziphantsi zohlulwe zibe yinitrogen eqhelekileyo kunye ne-ultra-low. Umxholo we-NOx wee-burners eziqhelekileyo uphakathi kwe-80mg / m3 kunye ne-150mg / m3, ngelixa umxholo we-NOx we-Ultra-low NOx burners ungaphantsi kwe-30mg / m3.

Ukuguqulwa kwe-ammonia ephantsi kweebhoyili ezivuthayo zegesi ziqhutyelwa ikakhulu ngeendlela ezimbini ezingentla. I-Burner low nitrogen retrofit, ngokuqhelekileyo ifanelekile kwiibhoyila ezincinci zegesi. Ukuba ibhoyili yegesi enkulu kufuneka ihlaziywe nge-nitrogen ephantsi, isithando somlilo kunye nesitshisi kufuneka siqhutywe ngexesha elifanayo, ukwenzela ukuba ibhoyili eyintloko kunye ne-burner inokuhambelana kwaye isebenze ngokufanelekileyo.
