Hauv teb ntawm kev lag luam flue roj saib xyuas, cov kua qaub lwg taw tes rau tus kws tshuaj ntsuamUa si lub luag haujlwm tseem ceeb yog cov cuab yeej tseem ceeb. It can not only help enterprises accurately understand the acid dew point temperature of flue gas, but also provide key data support for reducing equipment corrosion and optimizing the combustion process. Kab lus no yuav qhia tau meej raws li txoj cai ua haujlwm ntawm cov kua qaub lwgPoint AnalyzerThiab nws daim ntawv thov hauv kev lag luam flue gas saib xyuas.
1. Ua haujlwm ua haujlwm ntawmAcid WewPoint Analyzer
Tus txheej txheem ua hauj lwm ntawm cov acid lwg pointalyzeryog ua raws cov hws cov yam ntxwv ntawm sulfuric acid vapor hauv Flue roj. When burning high-sulfur fuel, part of the sulfur dioxide (SO2) formed after combustion will be further oxidized into sulfur trioxide (SO3), and SO3 will combine with water vapor in the flue gas to form sulfuric acid vapor. Lub hws tawm kub ntawm sulfuric acid vapor nyob rau hauv flue roj yog hu ua acid lwg point, uas yog ntau dua li dej lwg. Qhov ntau so3 (lossis sulfuric acid vapor) cov ntsiab lus nyob rau hauv flue roj, ntau dua cov kua qaub lwg taw tes. Cov acid lwg taw rau hauv Flue roj tuaj yeem ncav cuag 140 ~ 160 ℃, lossis ntau dua.
Cov acid lwg pointionalalyzerreflects the SO3 content in the flue gas and the possible corrosion risk to the equipment by measuring the acid dew point temperature in the flue gas. Hauv kev siv cov kev siv, cov kua qaub lwgPoint AnalyzerFeem ntau muaj cov kev sojntsuam hlau stainless hlau nrog kev ua haujlwm daim iav sensor tau nruab rau ntawm kev sojntsuam. Muaj ob electrodes nyob rau saum npoo ntawm sensor kom pom cov kua ntoos tso nyiaj. Qhov ntsuas kub ntawm lub sensor nto yog tswj los ntawm tus ntws ntws ntawm txias txias ntawm txias txias compressed huab cua. When the acid dew point probe is inserted into the flue gas and cooling compressed air is supplied, the temperature of the sensor surface drops until a sulfuric acid film begins to form on the mirror sensor surface. Nyob rau lub sijhawm no, cov ntsuas tau txiav txim siab ntsuas qhov kub ntawm cov acid lwg taw qhia los ntawm kev ntsuas qhov hloov pauv ntawm cov nplaim hluav taws xob.
2. Daim ntawv thov ntawm acid lwgPoint Analyzer Hauv kev lag luam flue gas saib xyuas
Corrosion saib xyuas thiab tiv thaiv:
The acid dew point temperature is an important indicator to measure the degree of low-temperature corrosion of the flue gas on the heating surface. Lub siab dua cov lwg taw tes, tus dav dav rau corrosion ntau thiab qhov hnyav dua rau corrosion. Through the monitoring of the acid dew point analyzer, the enterprise can timely understand the acid dew point temperature of the flue gas, so as to take corresponding anti-corrosion measures, such as improving the material grade of the heating surface, optimizing the flue gas flow path, etc., to reduce equipment corrosion and extend the service life.
Cov txheej txheem sib txuas ua kom zoo dua:
Cov ntaub ntawv tshuaj xyuas ntawm cov acid lwg taw tes tshuaj ntsuamYuav tuaj yeem muab cov lus qhia rau kev ua kom zoo ntawm cov txheej txheem combustion. By comparing the acid dew point temperature under different combustion conditions, enterprises can adjust parameters such as fuel type and combustion method to reduce the SO3 content in the flue gas, thereby reducing the acid dew point temperature and reducing the risk of corrosion. Nyob rau tib lub sijhawm, qhov no tseem pab txhim kho kev sib txuas kev ua tau zoo thiab txo kev siv zog siv zog.
Ib puag ncig xyuas kev soj ntsuam:
Raws li cov kev cai ib puag ncig ua cov hlua khi ua kom muaj kev nce qib, cov tuam txhab yuav tsum saib xyuas cov pa roj hluav taws kub ntau ntxiv. Raws li ib qho ntawm cov cuab yeej tseem ceeb rau Flue Gas Saib Xyuas, cov kua qaub lwg taw tes rau tus kws tshuaj ntsuamTuaj yeem pab cov tuam txhab uas nkag siab yog qhov tseeb cov ntsiab lus SO3 hauv Flue roj, yog li ua kom muaj kev vam meej uas yog cov qauv roj teeb ib puag ncig. Qhov no yog qhov tseem ceeb rau kev txhim kho kev txhim kho ntawm cov lag luam.
3. Kev ceev faj rau kev siv cov kua qaub lwgPoint Analyzer
Thaum siv ib qho kua qaub Ntse taw tes Analyzer, them sai sai rau cov ntsiab lus hauv qab no:
Ua kom ntsuas tau qhov tseeb:Calibrate cov acid lwg pointionatortsis tu ncua kom ntseeg tau nws qhov ntsuas ntsuas yog. At the same time, during the measurement process, pay attention to avoid interference factors such as smoke, high wind speed, etc., which may affect the measurement results.
Xaiv qhov chaw tsim nyog:Cov chaw teeb tsa ntawm cov acid lwg taw tes tshuaj ntsuamYuav tsum tau xaiv nyob rau hauv ib thaj chaw uas muaj cov pa roj ruaj khov thiab sawv cev kom muaj kev ntseeg tau ntawm qhov ntsuas tau.
Tu txij nkawm:
Acid Dew taw tes Analyzers muaj dav thov cov kev cia siab hauv kev lag luam flue gas saib. By accurately measuring the acid dew point temperature of flue gas, companies can timely understand the corrosion risk of flue gas, optimize the combustion process, and ensure environmental compliance. At the same time, when using acid dew point analyzers, attention should be paid to measurement accuracy, selection of appropriate installation locations, and regular maintenance. Nws ntseeg tau tias nrog kev nce qib nruam ntawm kev siv thev naus laus zis thiab kev nthuav dav ntxiv ntawm cov ntawv thov teb,Acid WewPoint Analyzers Yuav ua lub luag haujlwm tseem ceeb dua hauv Flue Gas Saib Xyuas.
