Ntau npaum li cas muaj zog yog qhov tag nrho Oxygen combustion iav rauv piv rau cov tsoos iav rauv raws li cov ntaub ntawv tseeb

Ntau npaum li cas muaj zog yog tag nrho cov pa oxygen combustion iav rauv piv rau cov tsoos iav furnaces raws li cov ntaub ntawv tseeb

Daim ntawv thov ntawm tag nrho oxygen combustion technology nyob rau hauv iav furnaces muaj ntau yam zoo. Cov kab lus dhau los twb tau qhia nws kom meej, yog li kuv yuav tsis mus rau hauv kev nthuav dav ntawm no. Hnub no, kuv yuav qhia koj txog cov ntaub ntawv tiag tiag kom pom tias muaj zog npaum li cas cov pa oxygen combustion iav rauv tau muab piv rau cov huab cua pab combustion iav rauv hauv qhov kev siv?

1. Kev sib piv ntawm qhov tseeb flue gas ntau lawm ntawm tag nrho cov pa combustion thiab huab cua pab combustion nyob rau hauv lub khob rauv. Los ntawm kev sib piv cov khoom siv hluav taws xob tiag tiag ntawm lub tuam txhab hauv tsev 600T / D ntab iav qhov cub siv cov pa puv thiab lwm qhov 600T / D ntab iav rauv siv cua pab combustion, cov roj flue ntau lawm ntawm oxygen combustion yog kwv yees li ib feem peb ntawm cov huab cua. pab combustion, uas yog deb tshaj qhov xav tau ntawm huab cua thiab flue gas ntau lawm thaum huab cua pab combustion; Cov ntsiab lus ntawm SO ₂ nyob rau hauv cov pa roj ntawm tag nrho cov pa combustion tsuas yog 53 feem pua ​​ntawm cov pa pab combustion, thiab cov ntsiab lus ntawm NOx tsuas yog 26 feem pua ​​ntawm cov pa pab combustion, zoo heev txo cov emission ntawm pa pa pa, tshwj xeeb tshaj yog NOx. ; Thov xa mus rau Table 1 kom paub meej.

2. Kev sib piv ntawm kev siv hluav taws xob ntawm cov pa oxygen combustion thiab huab cua pab combustion nyob rau hauv iav furnaces. Nyob rau hauv cov huab cua pab combustion ua hauj lwm, nws yog ib qhov tsim nyog los ua kom sov ib tug loj npaum li cas ntawm nitrogen gas, uas tsis muaj txiaj ntsim rau lub cua sov txheej txheem, mus rau lub khiav hauj lwm kub ntawm lub cub tawg thiab nkim ib tug loj npaum li cas ntawm lub zog. Siv methane natural gas combustion ua piv txwv:

Cua pab combustion: CH ₄ ntxiv 2O ₂ ntxiv rau 7.5N ₂=CO ₂ ntxiv 2H ₂ O ntxiv rau 7.5N ₂

Tag nrho cov pa oxygen combustion: CH ₄ ntxiv 2O ₂=CO ₂ ntxiv 2H ₂ O

Feem ntau, tsuas yog 21 feem pua ​​​​ntawm cov cua tag nrho yog siv los ntawm cov pa oxygen hauv huab cua combustion, thaum qhov seem ntawm 78 feem pua ​​​​ntawm nitrogen tsis tsuas yog tsis txhawb kev sib txuas, tab sis kuj nqa cov cua kub ntau ntawm cov pa taws. Nyob rau hauv cov ntaub ntawv ntawm kev siv tag nrho cov pa combustion, tus nqi ntawm cov huab cua yuav tsum tau rau roj combustion txo, thiab cov cua kub nqa tawm los ntawm cov pa roj txo; Tag nrho combusted, tsis muaj me me cubs los yog cua sov cia chamber, nrog tsawg kawg nkaus tshav kub dissipation thiab tseem ceeb zog-txuag teebmeem.

3. Kev sib piv ntawm cov nqi khiav lag luam hauv cov iav tsim: Piv nrog cov cua pab cuam combustion, oxyfuel combustion muaj tag nrho cov roj combustion, kub nplaim taws kub, muaj zog hluav taws xob muaj peev xwm, thiab nplaim hluav taws xob tuaj yeem ua kom kub ntawm cov iav kua los ntawm li 100 degree.
