ob,Tsawg nitrogen boilers ua haujlwm li cas

Tsawg-nitrogen boilers tau hloov kho raws li cov boilers zoo tib yam. Piv nrog rau cov tsoos boilers, tsawg-nitrogen boilers feem ntau siv ntau yam combustion optimization tswj technologies kom txo combustion kub, li no txo ​​NOx emissions, thiab yooj yim cuag NOx emissions tsawg dua 80mg / m3, Txawm tias ib co tsawg nitrogen boiler NOx emissions yuav tsawg li 30mg. /m3.

Lub tshuab hluav taws xob qis nitrogen feem ntau tswj qhov kub thiab txias thiab txo qhov tsim ntawm thermal nitrogen oxides.

peb,Yam tsawg nitrogen boilers muaj?

1、Flue gas recirculation tsawg nitrogen boiler

Lub flue gas recirculation low-nitrogen boiler yog lub taub hau siab uas siv combustion-txhawb cua los nqus ib feem ntawm combustion flue gas rov qab rau hauv lub burner, qhov twg nws yog tov nrog cua rau combustion. Vim lub recirculation ntawm flue roj, lub tshav kub muaj peev xwm ntawm combustion flue roj yog loj, thiaj li hais tias lub combustion kub yog tswj ntawm 1000 degrees, yog li txo qhov tsim ntawm nitrogen oxides.

2、Siab premixed tsawg nitrogen boiler

Lub siab premixed low-nitrogen boiler txais cov tshuab ua ntej sib xyaw ua ke, uas tuaj yeem ua tiav qhov kev sib xyaw zoo sib xws los ntawm kev kho cov pa roj thiab combustion cua, thiab ua tiav cov roj combustion tiav. Thiab cov hluav taws xob tsawg-nitrogen boiler tuaj yeem tsim cov roj sib xyaw ua ke ua ntej cov pa roj thiab cov pa hluav taws xob txhawb nqa nkag mus rau hauv lub cub tawg, thiab tom qab ntawd hlawv kom ruaj khov, txo cov pa tawm ntawm nitrogen oxides.

Qhov zoo: niaj hnub radiator hloov hluav taws xob, txhim kho kev siv hluav taws xob hloov pauv; optimum combustion ceev, kub thiab kev nyab xeeb; nce hluav taws xob cheeb tsam; adjustable unit radiation siv; Rov qab latent cua sov ntawm vaporization.

Plaub,Retrofit ntawm Tsawg Nitrogen Boiler

01)Boiler Tsawg Nitrogen Retrofit

>

Boiler low-nitrogen transformation yog flue gas recirculation thev naus laus zis, uas yog cov cuab yeej siv los txo cov nitrogen oxides los ntawm kev rov ua dua ib feem ntawm cov pa hluav taws xob boiler rau hauv lub cub tawg thiab sib tov nrog cov pa roj thiab cua rau combustion. Siv cov tshuab hluav taws xob rov ua dua tshiab, qhov kub ntawm qhov kub ntawm qhov chaw ntawm lub boiler yog txo, thiab cov cua coefficient tsis hloov. Nyob rau hauv cov xwm txheej uas lub boiler efficiency tsis txo, qhov tsim ntawm nitrogen oxides yog inhibited, thiab lub hom phiaj ntawm kev txo nitrogen oxide emissions tiav.

Txhawm rau kom ua tiav cov roj combustion, feem ntau nws yog qhov tsim nyog los muab qee qhov kev faib ua feem ntawm cov huab cua ntau ntxiv nrog rau qhov theoretical huab cua ntim xav tau rau combustion. Nyob rau hauv qhov chaw ntawm kev ua kom lub thermal efficiency ntawm combustion, ib tug me me tshaj cua coefficient yog xaiv los txo cov pa concentration nyob rau hauv lub flue gas. , yuav muaj peev xwm inhibit qhov tsim ntawm NOx.

Qhov tseeb, kev hloov pauv tsis tshua muaj nitrogen ntawm cov boilers yog flue gas recirculation thev naus laus zis, uas yog cov cuab yeej siv los txo cov nitrogen oxides los ntawm kev rov ua dua ib feem ntawm cov pa hluav taws xob boiler rau hauv qhov cub thiab sib tov nrog cov pa roj carbon monoxide thiab cua rau combustion. Siv cov tshuab hluav taws xob rov ua dua tshiab, qhov kub ntawm qhov kub ntawm qhov chaw ntawm lub boiler yog txo, thiab cov cua coefficient tsis hloov. Nyob rau hauv cov xwm txheej uas lub boiler efficiency tsis txo, qhov tsim ntawm nitrogen oxides yog suppressed, thiab lub hom phiaj ntawm txo nitrogen oxide emissions tiav.

Thaum lub boiler khiav ntawm siab load, cov huab cua ntim ntawm lub blower feem ntau yog nce mus rau qhov kub thiab txias. Nyob rau lub sijhawm no, cov cua coefficient feem ntau loj, qhov kub ntawm lub cub tawg yog siab, thiab tus nqi ntawm NOx generated yog loj. Lub boiler qis-nitrogen ua haujlwm zoo nyob rau hauv cov xwm txheej siab, thiab tib lub sijhawm tswj cov cua sov kub, uas tuaj yeem cuam tshuam cov tiam ntawm NOx.

NOx nitrogen oxides yog tsim los ntawm oxidation ntawm N2 nyob rau hauv combustion cua nyob rau hauv qhov kev txiav txim ntawm kub kub. Kev hloov pauv tsis tshua muaj nitrogen tuaj yeem tswj tau qhov kub thiab txias hauv qab 1000 degrees. concentration yog heev txo.

02）Tsawg-nitrogen Retrofit ntawm Gas Boiler

1）Boiler lub ntsiab lub cev renovation

Rau kev hloov pauv tsis tshua muaj nitrogen ntawm cov khoom siv hluav taws xob loj loj, feem ntau nws yog qhov tsim nyog los hloov lub qhov cub thiab qhov cua sov, kom cov roj boiler hlawv ntau dua, thiab cov ntsiab lus nitrogen oxide hauv cov roj flue txo qis dua, thiab thaum kawg. Lub hom phiaj ntawm low-nitrogen gas transformation yog tiav.

2）Burner Retrofit

Feem ntau hais lus, qhov tsawg nitrogen retrofit txoj kev rau cov roj boilers yog burner retrofit. Peb xaiv los hloov lub tshuab hluav taws xob qis kom ua rau lub tshuab hluav taws xob ntau zog-txuag, tus phooj ywg ib puag ncig thiab ua haujlwm tau zoo, yog li txo cov ntsiab lus ntawm ammonia oxides hauv boiler tso. Low-nitrogen burners tau muab faib ua tej yam zoo tib yam thiab ultra-tsawg nitrogen. Cov ntsiab lus NOx ntawm cov burners zoo tib yam yog nyob nruab nrab ntawm 80mg / m3 thiab 150mg / m3, thaum NOx cov ntsiab lus ntawm ultra-low NOx burners yog qis dua 30mg / m3.

Qhov tsawg-ammonia hloov pauv ntawm cov roj hluav taws xob boilers feem ntau yog ua los ntawm ob txoj hauv kev saum toj no. Burner tsawg nitrogen retrofit, feem ntau haum rau cov roj boilers me me. Yog hais tias lub boiler loj loj yuav tsum tau retrofitted nrog tsawg nitrogen, lub cub tawg thiab lub burner yuav tsum tau nqa tawm nyob rau tib lub sij hawm, thiaj li hais tias lub ntsiab boiler thiab lub burner yuav tsum matched thiab ua hauj lwm zoo.
