Poshi,Chii chinonzi low nitrogen boiler?

Yakaderera-nitrogen boilers kazhinji inoreva kune gasi-anopisa boilers ane nitrogen oxide emissions pazasi 80mg/m3.

• Ultra-yakakwirira kushanda (kusvika ku108%);
• Ultra-yakaderera emission yezvinhu zvinokuvadza (NOX iri pasi pe8ppm/18mg/m3);
• Ultra-yakaderera tsoka (1.6m2/tonnage);
• Ultra-intelligent control (Siemens controller);
• Ultra-yakaderera kupera gasi tembiricha (yakadzika se35℃);
• Ultra-yakanyarara kushanda (45 dB);
• Ultra-kuchengetedzwa kwekuchengetedza (11 zvikamu zvekudzivirira);
• Super exquisite kutaridzika (inotonhorera chena chitarisiko);
• Super user-friendly control panel (LCD);
• Hupenyu hurefu hwebasa (makore makumi mana);
• Ultra-yakaderera gasi kumanikidzwa (1.7 ~ 2.1kpa);
• Ultra-yakakwirira chiyero chekugadzirisa chiyero: 1: 7 (15 ~ 100%);
• Universal mutoro unotakura vhiri (nyore kutakura uye kugadzirisa).

piri,Iyo yakaderera sei nitrogen boilers inoshanda

Low-nitrogen boilers inokwidziridzwa pahwaro hweakajairwa boilers. Kuenzaniswa nemabhailer echinyakare, mabhoilers epasi-nitrogen anonyanya kushandisa akasiyana dhizaini ekudzora tekinoroji kuderedza kupisa kwekupisa, nekudaro kuderedza NOx emissions, uye kuwana nyore NOx emissions isingasviki 80mg/m3, Kunyange imwe yakaderera nitrogen boiler NOx emissions inogona kunge yakaderera se30mg. /m3.

Iyo yakaderera nitrogen combustion tekinoroji inonyanya kudzora tembiricha yekupisa uye inoderedza chizvarwa chekupisa nitrogen oxides.

tatu,Ndeapi marudzi eyakaderera nitrogen boilers aripo?

1、Flue gasi recirculation yakaderera nitrogen boiler

Iyo flue gasi recirculation yakaderera-nitrogen bhaira idzvinyiriro yemusoro inoshandisa mhepo inotsigira kupisa kusveta chikamu chemoto unopisa gasi kudzoka mumoto, umo inosanganiswa nemhepo yekupisa. Nekuda kwekutendererazve kwegasi reflue, huwandu hwekupisa hwemhepo inopisa gasi yakakura, zvekuti tembiricha yekupisa inodzorwa pa1000 madhigirii, nekudaro ichideredza kuumbwa kwenitrogen oxides.

2、Yakazara premixed yakaderera nitrogen boiler

Iyo yakazara premixed yakaderera-nitrogen boiler inotora iyo yakazara premixed tekinoroji, iyo inogona kuwana yakanakira kusanganisa reshiyo nekugadzirisa gasi uye mhepo inopisa, uye kuwana kupisa kwakazara kwehuni. Uye iyo yakaderera-nitrogen boiler burner inogona kuumba musanganiswa wakafanana gasi musanganiswa usati gasi uye mweya unotsigira kupisa unopinda muchoto, uye wobva wapisa zvakadzikama, uchideredza kubuda kwenitrogen oxide.

Zvakanakira: yunifomu radiator kupisa kuchinjika, yakagadziridzwa kupisa kupisa kusimba; optimal combustion kumhanya, tembiricha uye kuchengeteka; kuwedzera kwemwaranzi nzvimbo; inogadziriswa chikwata nemwaranzi simba; Kudzoreredza kwekupisa kwakadzikama kwe vaporization.

Zvina,Retrofit yeLow Nitrogen Boiler

01)Boiler Yakaderera Nitrogen Retrofit

>

Boiler yakaderera-nitrogen shanduko ndeye flue gasi recirculation tekinoroji, inova tekinoroji yekudzikisa nitrogen oxides nekudzoreredza chikamu cheiyo boiler inoburitsa utsi muchoto nekuisanganisa negasi rechisikigo uye mweya wekupisa. Uchishandisa flue gasi recirculation tekinoroji, kupisa kwekupisa munzvimbo yepakati yebhailer kunoderedzwa, uye yakawandisa mhepo coefficient inoramba isingachinji. Pasi pemamiriro ekuti bhodha inoshanda haina kuderedzwa, kuumbwa kwe nitrogen oxides kunodziviswa, uye chinangwa chekudzikisa nitrogen oxide emissions inowanikwa.

Kuti uve nechokwadi chekupisa kwakazara kwemafuta, zvinowanzodikanwa kupa chimwe chikamu chemhepo yakawandisa kuwedzera kune theoretical air volume inodiwa pakupisa. Pamusoro pekuita kuti kuve nechokwadi chekushanda kwekushisa kwekupisa, diki diki yakawandisa yemhepo coefficient inosarudzwa kuti ideredze huwandu hweokisijeni mumhepo yeflue. , ichakwanisa kuvharidzira zvinobudirira kuumbwa kweNOx.

Muchokwadi, iyo yakaderera-nitrogen shanduko yemaboilers tekinoroji gasi recirculation tekinoroji, inova tekinoroji yekudzikisa nitrogen oxides nekudzoreredza chikamu cheiyo boiler yekuburitsa utsi muchoto nekuisanganisa negasi rechisikigo uye mweya wekupisa. Uchishandisa flue gasi recirculation tekinoroji, kupisa kwekupisa munzvimbo yepakati yebhailer kunoderedzwa, uye yakawandisa mhepo coefficient inoramba isingachinji. Pasi pemamiriro ekuti bhodha inoshanda haina kuderedzwa, kuumbwa kwe nitrogen oxides kunodzvinyirirwa, uye chinangwa chekudzikisa nitrogen oxide emissions inowanikwa.

Kana iyo bhailer iri kushanda pamutoro wakakwira, huwandu hwemhepo hwemhepo inoputika inowanzowedzerwa kuwedzera tembiricha yevira. Panguva ino, iyo yakawandisa mhepo coefficient kazhinji yakakura, tembiricha yevira yakakwira, uye huwandu hweNOx hunogadzirwa hwakakura. Iyo yakaderera-nitrogen bhaira inomhanya zvakanaka pasi pemamiriro emutoro wepamusoro, uye panguva imwechete inodzora tembiricha yechoto, iyo inogona kunyatso kudzvinyirira chizvarwa cheNOx.

NOx nitrogen oxides inogadzirwa nekuda kweiyo oxidation yeN2 mumhepo inopisa pasi pekuita kwekupisa kwakanyanya. Iyo yakaderera-nitrogen shanduko inogona kunyatso kudzora tembiricha yekupisa iri pasi pe1000 madhigirii. concentration yakaderera zvikuru.

02）Yakaderera-nitrogen Retrofit yeGasi Boiler

1）Boiler main body renovation

Kune yakaderera-nitrogen shanduko yeakawanda mahombe echinyakare simbi mavira, zvinowanzodikanwa kushandura choto uye kupisa nzvimbo, kuitira kuti gasi bhaira rinopisa zvakazara, uye iyo nitrogen oxide zviri mu flue gasi inowedzera kuderedzwa, uye pakupedzisira. chinangwa chepasi-nitrogen gasi shanduko inowanikwa.

2）Burner Retrofit

Kazhinji kutaura, iyo yakaderera nitrogen retrofit nzira yegasi boilers ndeye burner retrofit. Isu tinosarudza kutsiva iyo yakaderera-nitrogen inopisa kuita kuti iyo inopisa iwedzere kuchengetedza simba, yakatenderedza nharaunda uye inoshanda, nekudaro kuderedza zvirimo zveammonia oxides mubhailer exhaust. Low-nitrogen burners yakakamurwa kuva yakajairwa uye Ultra-yakaderera nitrogen. Izvo NOx zvemukati zvezvinopisa zvinopisa zviri pakati pe80mg/m3 uye 150mg/m3, nepo NOx yemukati meiyo yakanyanya-yakaderera NOx zvinopisa yakaderera pane 30mg/m3.

Iyo yakaderera-ammonia shanduko yegesi-inopfuta boilers inonyanya kuitwa nenzira mbiri dziri pamusoro. Burner yakaderera nitrogen retrofit, kazhinji yakakodzera kune madiki gasi boilers. Kana iyo hombe yegesi bhaira ichizogadziriswa ne nitrogen yakaderera, choto uye chinopisa chinoda kuitwa panguva imwe chete, kuitira kuti bhaira huru uye mbavha zvienderane uye zvishandiswe zvakanaka.
