chimodzi,Kodi boiler ya nayitrogeni yochepa ndi chiyani?

Ma boiler a nayitrogeni otsika nthawi zambiri amatanthawuza ma boiler oyaka ndi mpweya okhala ndi mpweya wa nitrogen oxide pansi pa 80mg/m3.

• Kuchita bwino kwambiri (mpaka 108%);
• Kutulutsa kotsika kwambiri kwa zinthu zovulaza (NOX ndi yochepera 8ppm/18mg/m3);
• Mapazi otsika kwambiri (1.6m2/tonnage);
• Kuwongolera kwanzeru kwambiri (wolamulira wa Simens);
• Kutentha kwamafuta otsika kwambiri (otsika mpaka 35).℃);
• Kuchita kwachete kwambiri (45 dB);
• Chitetezo champhamvu kwambiri (magawo 11 achitetezo);
• Kuwoneka kokongola kwambiri (mawonekedwe oyera oyera);
• Super user-friendly control panel (LCD);
• Moyo wautali wautumiki (zaka 40);
• Kuthamanga kwambiri kwa gasi (1.7 ~ 2.1kpa);
• Kusintha kwapamwamba kwambiri: 1: 7 (15 ~ 100%);
• Universal katundu wonyamula gudumu (osavuta kunyamula ndi kukonza).

awiri,Momwe ma boiler a nayitrogeni amagwirira ntchito

Ma boiler otsika a nayitrogeni amasinthidwa pamaziko a ma boiler wamba. Poyerekeza ndi boilers chikhalidwe, otsika nayitrogeni boilers makamaka ntchito zosiyanasiyana kukhathamiritsa kukhathamiritsa matekinoloje kuchepetsa kuyaka kutentha, potero kuchepetsa mpweya NOx, ndi kupeza mosavuta NOx mpweya zosakwana 80mg/m3, Ngakhale ena otsika nayitrogeni boilers mpweya mpweya NOx kungakhale otsika monga 30mg. /m3.

Ukadaulo wocheperako wa nayitrogeni makamaka umayang'anira kutentha kwa kuyaka ndikuchepetsa kutulutsa kwa ma nitrogen oxides otentha.

atatu,Ndi mitundu yanji ya ma boiler otsika a nayitrogeni omwe alipo?

1、Flue gasi recirculation low nayitrogeni boiler

The flue gas recirculation low-nitrogen boiler ndi mutu wopondereza womwe umagwiritsa ntchito mpweya wothandizira kuyaka kuti uyamwe mbali ya gasi woyaka moto mu chowotcha, pomwe umasakanizidwa ndi mpweya kuti uyake. Chifukwa cha recirculation wa mpweya chitoliro, kutentha mphamvu ya kuyaka chitoliro mpweya waukulu, kotero kuti kuyaka kutentha amalamulidwa pa madigiri 1000, potero kuchepetsa mapangidwe oxides nayitrogeni.

2、Kokwanira premixed otsika nayitrogeni boilers

Chowotchera chophatikizika bwino cha nayitrogeni chimatenga ukadaulo wosakanizidwa bwino, womwe ungathe kukwaniritsa chiŵerengero chosakanikirana bwino posintha mpweya ndi mpweya woyaka, ndikukwaniritsa kuyaka kwathunthu kwamafuta. Ndipo chowotchera cha nayitrogeni chocheperako chimatha kupanga chisakanizo chosakanikirana cha gasi chisanalowe m'ng'anjo yamoto ndi mpweya wothandizira kutentha, ndikuwotcha mokhazikika, kuchepetsa kutulutsa kwa nitrogen oxide.

>

Ubwino: yunifolomu rediyeta kutentha kutengerapo, kusintha kutentha kutengerapo kwambiri; mulingo woyenera kuyaka liwiro, kutentha ndi chitetezo; kuchuluka kwa radiation; chosinthika unit ma radiation mwamphamvu; Kuchira kobisika kutentha kwa vaporization.

Zinayi,Kubwezeretsanso kwa Boiler Yotsika ya Nayitrogeni

01)Boiler Low Nayitrogeni Retrofit

>

Kusintha kwa ma boiler otsika ndi nayitrogeni ndiukadaulo wowongolera mpweya wa flue, womwe ndi ukadaulo wochepetsera ma nitrogen oxide pobweretsanso gawo lina la utsi wothira mu ng'anjo ndikusakaniza ndi gasi wachilengedwe ndi mpweya kuti uyake. Pogwiritsa ntchito ukadaulo wowongolera mpweya wa flue, kutentha kwapakati pa boiler kumachepetsedwa, ndipo kuchuluka kwa mpweya wowonjezera sikusintha. Pokhala kuti kutentha kwa boiler sikuchepa, mapangidwe a nitrogen oxides amaletsedwa, ndipo cholinga chochepetsera mpweya wa nitrogen oxide chimatheka.

Pofuna kuonetsetsa kuyaka kwathunthu kwa mafuta, nthawi zambiri kumakhala kofunikira kupereka gawo lina la mpweya wochulukirapo kuwonjezera pa kuchuluka kwa mpweya wofunikira kuti uyake. Pamaziko owonetsetsa kuti kuyaka kwamafuta kumatenthedwa, kagawo kakang'ono kowonjezera ka mpweya kumasankhidwa kuti achepetse kuchuluka kwa okosijeni mu gasi wa flue. , azitha kuletsa bwino mapangidwe a NOx.

M'malo mwake, kusinthika kwa nayitrogeni kwa ma boilers ndiukadaulo wowongolera mpweya wa flue, womwe ndi ukadaulo wochepetsera ma nitrogen oxide pobweretsanso gawo lina la utsi wotulutsa utsi mu ng'anjo ndikusakaniza ndi gasi ndi mpweya kuti uyake. Pogwiritsa ntchito ukadaulo wowongolera mpweya wa flue, kutentha kwapakati pa boiler kumachepetsedwa, ndipo kuchuluka kwa mpweya wowonjezera sikusintha. Pokhala kuti kutentha kwa boiler sikuchepa, mapangidwe a nitrogen oxides amaponderezedwa, ndipo cholinga chochepetsera mpweya wa nitrogen oxide chimatheka.

Pamene chowotchera chikuyenda kwambiri, kuchuluka kwa mpweya wa chowombera nthawi zambiri kumawonjezera kutentha kwa ng'anjo. Panthawiyi, mpweya wochuluka wa mpweya nthawi zambiri umakhala waukulu, kutentha kwa ng'anjo kumakhala kwakukulu, ndipo kuchuluka kwa NOx komwe kumapangidwa kumakhala kwakukulu. Chowotcha chochepa cha nayitrogeni chimayenda bwino pansi pa katundu wambiri, ndipo nthawi yomweyo chimayang'anira kutentha kwa ng'anjo, zomwe zingathe kupondereza m'badwo wa NOx.

NOx nitrogen oxides amapangidwa chifukwa cha okosijeni wa N2 mu mpweya woyaka chifukwa cha kutentha kwambiri. Kusintha kwa nayitrogeni wocheperako kumatha kuwongolera kutentha kwa kutentha pansi pa madigiri 1000. ndende imachepetsedwa kwambiri.

02）Kubwezeretsanso kwa Nayitrogeni Wotsika wa Boiler ya Gasi

1）Kukonzanso kwa boiler yayikulu

Pakuti otsika nayitrogeni kusintha ambiri zikuluzikulu chikhalidwe ng'anjo zitsulo, nthawi zambiri kofunika kusintha ng'anjo ndi Kutentha m'dera, kuti mpweya kukatentha amayaka kwambiri, ndi nayitrogeni okusayidi zili mu mpweya chitoliro zina yafupika, ndipo potsiriza. Cholinga cha kusintha kwa mpweya wa nayitrogeni wochepa kumatheka.

2）Burner Retrofit

Nthawi zambiri, njira yotsika ya nitrogen retrofit yama boilers a gasi ndi retrofit burner. Timasankha kusintha chowotcha chochepa cha nayitrogeni kuti chowotcheracho chiwotchera kwambiri, chowotchera kuti chiteteze chilengedwe komanso chothandiza, potero timachepetsa zomwe zili mu ammonia oxides muutsi wa boiler. Mawotchi otsika a nayitrogeni amagawidwa kukhala wamba komanso otsika kwambiri nayitrogeni. Zomwe zili mu NOx zowotcha wamba zili pakati pa 80mg/m3 ndi 150mg/m3, pomwe NOx zowotcha zotsika kwambiri za NOx ndizotsika kuposa 30mg/m3.

Kusintha kwa ammonia otsika kwa ma boilers otenthetsera mpweya kumachitika makamaka m'njira ziwiri pamwambapa. Chowotcha chochepa cha nitrogen retrofit, chomwe chimakhala choyenera pama boiler ang'onoang'ono a gasi. Ngati chowotcha chachikulu cha gasi chiyenera kubwezeretsedwanso ndi nayitrogeni yochepa, ng'anjo ndi chowotcha ziyenera kuchitidwa nthawi imodzi, kuti chowotcha chachikulu ndi chowotchacho chigwirizane ndi kugwiritsidwa ntchito bwino.
