Ntawm qhov tod tes, nruj kev tiv thaiv ib puag ncig cov cai tseem txhawb cov chaw tsim khoom siv hluav taws xob kom ua tiav cov thev naus laus zis txuas ntxiv.Cov tsoos thee hluav taws xob boilers tau maj mam thim rov qab los ntawm cov keeb kwm theem, thiab cov hluav taws xob cua sov chav generators tshiab, tsis tshua muaj nitrogen chav generators thiab ultra-low nitrogen chav generators tau dhau los ua lub zog tseem ceeb hauv kev lag luam chav generator.
Low-nitrogen combustion steam generator yog hais txog lub tshuab hluav taws xob uas tsis muaj NOx emissions thaum lub sij hawm roj combustion.Lub NOx emission ntawm tsoos natural gas generator yog hais txog 120 ~ 150mg / m3, thaum lub emission ntawm tsawg nitrogen chav generator yog hais txog 30 ~
80mg / m2.NOx emissions qis dua 30mg / m3 feem ntau hu ua ultra-low nitrogen steam generators.
Qhov tseeb, kev hloov pauv tsis tshua muaj nitrogen ntawm lub boiler yog flue gas recirculation thev naus laus zis, uas yog ib qho cuab yeej siv los txo cov ammonia oxide los ntawm reintroducing ib feem ntawm lub boiler flue roj rau hauv lub cub tawg thiab hlawv nrog natural gas thiab cua.Los ntawm kev siv cov tshuab flue gas recirculation, qhov kub thiab txias hauv qhov chaw ntawm lub boiler yog txo thiab cov cua feem ntau tseem tsis hloov.Nyob rau hauv cov xwm txheej uas qhov ua tau zoo ntawm lub boiler tsis raug txo, kev tsim cov nitrogen oxides yog suppressed, thiab lub hom phiaj ntawm kev txo cov emission ntawm nitrogen oxides yog tiav.
Txhawm rau kuaj seb puas muaj nitrogen oxide emissions ntawm cov tshuab hluav taws xob qis nitrogen tuaj yeem ua tau raws li cov qauv emissions, peb tau ua tiav kev soj ntsuam emission ntawm cov tshuab hluav taws xob qis nitrogen hauv khw, thiab pom tias ntau lub tuam txhab muag cov khoom siv hluav taws xob zoo tib yam raws li cov lus hais ntawm low-nitrogen steam generators, dag cov neeg siv khoom nrog tus nqi qis.
Nws yog to taub hais tias ib txwm muaj tsawg-nitrogen chav generator manufacturers thiab burners yog mas los ntawm txawv teb chaws, thiab tus nqi ntawm ib tug burner yog siab li kaum tawm txhiab las.Cov neeg siv khoom tau ceeb toom kom tsis txhob raug ntxias los ntawm tus nqi qis thaum yuav khoom!Ntxiv thiab, xyuas cov ntaub ntawv NOx emission .
