Tam sim no, feem ntau ntawm cov cuab yeej ntsuas nitrogen oxide nyob rau hauv kev ua lag luam txiav txim siab cov ntsiab lus ntawm nitrogen dioxide (NO₂) lossis tag nrho cov nitrogen oxides (NOₓ) los ntawm thawj hloov NO₂ hauv tag nrho NOₓ (NO + NO₂) rau NO. Txawm li cas los xij, vim yog NO₂ / TSIS hloov pauv kev ua tau zoo (uas nyob ntawm qhov tseeb NO₂ concentration), qee qhov chaw ua haujlwm tsis haum rau kev siv lub tshuab hloov pauv nitrogen rau NO₂-rau-NO. Txhawm rau daws qhov teeb meem no, Shandong SINZEN Instrument Co., Ltd. tau tsim lub SUV-100 flue gas analyzer, uas ua haujlwm ncaj qha NO₂ ntsuas txoj kev ntsuas cov pa phem. Cov tshuaj ntsuam xyuas yog ua raws li ultraviolet absorption spectroscopy thiab chemometric algorithms. Nws tuaj yeem ntsuas qhov siab ntawm cov pa roj xws li SO₂, NO, NO₂, thiab O₂. Featuring siab ntsuas qhov tseeb, siab ntseeg siab, ceev teb lub sij hawm, thiab dav applicability, nws yuav siv tau dav siv nyob rau hauv ib puag ncig hauv internet saib xyuas, muaj kev tswj, kev ruaj ntseg xyuas, thiab lwm yam kev siv.

Nitrogen oxide analyzers yog cov cuab yeej tseem ceeb rau kev ua kom muaj kev tswj hwm kev tswj hwm, saib xyuas cov pa tawm, thiab txhim kho cov txheej txheem kev lag luam. Tsis tas li ntawd, lawv pab ntau yam kev lag luam hauv kev saib xyuas thiab tswj cov pa nitrogen oxide emissions, yog li pab kom ua raws li cov kev cai ib puag ncig thiab txo cov kev cuam tshuam ib puag ncig ntawm lawv txoj haujlwm. Los ntawm kev muab qhov tseeb, lub sijhawm ntsuas qhov ntsuas ntawm nitrogen oxide (NOₓ) concentrations, NOₓ analyzers pab txhawb kev siv cov kev ntsuas kev ua qias tuaj. Cov kev ntsuas no suav nrog kev kho cov txheej txheem combustion, optimizing huab cua-roj ratios, los yog txhim kho xaiv catalytic txo (SCR) systems. Hauv cov ntsiab lus, cov txheej txheem engineers siv nitrogen oxide analyzers los ntsuas thiab txheeb xyuas qhov concentration ntawm nitrogen oxides hauv cov qauv roj. Cov kws tshuaj ntsuam xyuas no ua lub luag haujlwm tseem ceeb hauv kev saib xyuas ib puag ncig, kev tswj cov pa tawm, thiab kev ua kom zoo tshaj plaws thoob plaws ntau qhov kev lag luam.

Lub SUV-100 flue gas analyzer tau txais ultraviolet qhov sib txawv ntawm qhov muag pom kev spectroscopy (DOAS) thev naus laus zis. Nws muaj peev xwm ntsuas qhov siab ntawm ntau cov pa roj xws li SO₂, NO, NO₂ thiab O₂, uas muaj qhov ntsuas qhov tseeb, kev ntseeg tau zoo thiab cov lus teb ceev ceev. Nws tuaj yeem siv dav hauv cov txheej txheem thiab kev tswj hwm kev nyab xeeb hauv kev tsim khoom hauv kev lag luam thoob plaws xws li kev lag luam cov txheej txheem roj saib xyuas, lub zog cog metallurgy, cement manufacturing, tshuaj chiv ntau lawm, tshuaj lom neeg kev lag luam, kev tiv thaiv ib puag ncig thiab kev tshawb fawb.
