Dab tsi yog qhov zoo ntawm kev siv cov thermocouples tshwj xeeb hauv kev ua cov thee?

Cov thermocouples tshwj xeeb tau dhau los ua cov cuab yeej tseem ceeb hauv kev ua haujlwm thee vim lawv muab ntau yam txiaj ntsig tsim nyog rau kev nyab xeeb thiab ua haujlwm zoo ntawm kev ua haujlwm sib txawv. Cov cuab yeej no yog cov neeg txhawb nqa tseem ceeb ntawm kev tswj xyuas kom zoo, kev txhim kho cov txheej txheem, thiab kev tiv thaiv kev phom sij, tsis yog qhov kub thiab txias - ntsuas cov cuab yeej.
Tsim los nrog qhov tseeb los ua kom tau raws li cov kev xav tau tshwj xeeb ntawm cov haujlwm no, cov thermocouples tshwj xeeb siv hauv kev ua cov thee yog Lawv khiav ntawm Seebeck effect, nyob rau hauv qhov kub sib txawv generates ib qhov hluav taws xob ntawm qhov sib txuas ntawm ob qhov sib txawv ntawm cov hlau. Lub tswv yim no ua rau muaj kev tswj xyuas qhov kub thiab txias nyob rau hauv qhov feem ntau xav tau thiab nyuaj thee ua cov chaw.
Lawv lub peev xwm los muab cov kev ntsuas ntsuas kub hauv cov ntawv thov kub kub yog ib qho txiaj ntsig tseem ceeb. Rau cov hluav taws xob hluav taws xob hluav taws xob, piv txwv li, boilers khiav ntawm qhov kub siab heev rau chav dej-hloov dej. Cov thermocouples tshwj xeeb tuaj yeem saib xyuas qhov kub ntawm boiler kom meej thiab tiv taus cov cua sov no. Qhov tseeb no yog qhov tseem ceeb vim tias qhov ntsuas kub kom raug txiav txim siab qhov ua tau zoo ntawm lub tshuab tsim hluav taws xob. Kev hloov pauv tsis tsim nyog ntawm cov thee lub zog rau hauv lub zog ntawm lub zog yuav tshwm sim los ntawm qhov kub thiab txias heev, yog li txo cov hluav taws xob ntau lawm. Zoo li sim khiav lub tsheb nrog lub cav tsis muaj zog, kev ua haujlwm yuav tsis zoo. Ntawm qhov tod tes, qhov kub thiab txias heev tuaj yeem ua rau cov phab ntsa boiler puas tsuaj, yog li tsim kom muaj kev nyab xeeb thiab kev kho kim. Cov thermocouples no lav tias lub boiler qhov kub yog qhov tseeb rau qhov zoo tshaj plaws lub zog tso zis, ib yam li cov twj paj nruag zoo tsim cov suab paj nruag zoo nkauj.
Tshwj xeeb yog cov thermocouples kuj tseem ceeb heev nyob rau hauv cov thee gasification systems. Hloov cov thee rau hauv cov roj synthesis los ntawm thee gasification nyob ntawm qhov ntsuas kub. Cov thermocouples nyob rau hauv lub gasifier tuaj yeem saib xyuas qhov kub thiab txias. Qhov zoo ntawm cov roj synthesis generated yuav muaj feem cuam tshuam los ntawm qhov kub thiab txias me ntsis. Piv txwv li, ib nrab gasification coj los ntawm qhov kub thiab txias tshaj qhov zoo tshaj plaws yuav txo qhov tso zis ntawm cov khoom siv roj. Qhov no zoo li cov txheej txheem tshuaj lom neeg hauv chav kuaj; kev hloov kho kub me ntsis yuav cuam tshuam tag nrho cov txiaj ntsig ntawm kev sim. Kev nyeem ntawv ntsuas kub ntawm cov thermocouples pab cov neeg ua haujlwm hloov cov txheej txheem kev teeb tsa yog li lav qhov kev pom zoo ntawm cov pa roj ntau lawm.
Lub neej ntev ntawm cov thermocouples tshwj xeeb ntxiv rau lwm qhov txiaj ntsig. Feem ntau ntim nrog plua plav, tshauv, thiab lwm yam khoom siv abrasive, cov chaw ua haujlwm thee kuj tseem tuaj yeem muaj cov roj corrosive ntawm tes. Cov ntaub ntawv thiab cov txheej tiv thaiv siv rau cov thermocouples tshwj xeeb tso cai rau lawv kom muaj sia nyob raws li cov kev xav tau no. Ceramic lossis tshwj xeeb alloys tiv taus corrosion thiab puas tuaj yeem tsim cov thermocouple lub tsho sab nrauv. Qhov kev ua siab ntev no lav tau lub neej ntev nyob rau hauv qhov chaw nres tsheb hluav taws xob hluav taws xob uas cov thermocouple raug txuas mus rau cov khoom los ntawm cov hluav taws xob hluav taws xob. Txhim khu kev ruaj ntseg thiab tsis tu ncua kev ntsuas kub yog ua tau los ntawm qhov ntsuas kub-sensing Cheebtsam, uas zoo ib yam li cov ris tsho tiv thaiv los ntawm kev tawm tsam tsis tu ncua ntawm cov xwm txheej ib puag ncig.
Ib qho txiaj ntsig tseem ceeb ntxiv ntawm kev hloov kho thermocouples yog lawv lub sijhawm ceev ceev. Kev kub ceev hauv kev ua cov thee tuaj yeem tshwm sim sai. Rau kev ua haujlwm thee ziab, piv txwv li, cov dej noo ntawm cov thee tuaj yeem cuam tshuam tus nqi ziab thiab qhov kub thiab txias. Qhov kub ntawm lub tshuab ziab khaub ncaws tuaj yeem hloov pauv sai yog tias qhov kub ntawm qhov siv los yog qhov noo noo hloov tam sim ntawd. Cov tshuaj tiv thaiv ceev ceev lub sij hawm thermocouples tuaj yeem txheeb xyuas cov kev hloov pauv no sai thiab ceeb toom rau kev tswj hwm. Qhov no tau lees tias cov thee tau qhuav mus rau qhov xav tau noo noo yam tsis muaj overheating lossis underdrying, yog li ua kom muaj kev hloov pauv sai rau cov txheej txheem ziab. Nws zoo li tus neeg ncaws pob nrawm nrawm tuaj yeem hloov kho qhov hloov pauv hauv ib puag ncig kev ua si kom tau txais qhov ua tau zoo tshaj plaws.
Ntxiv mus, qee qhov thermocouples txhawb kev nyab xeeb ntawm kev ua haujlwm thee. Kev tswj qhov kub thiab txias hauv cov chaw cia khoom yog qhov tseem ceeb heev kom tsis txhob muaj kev sib tsoo tshwm sim. Yog hais tias qhov kub thiab txias hauv pawg cia siab dhau lawm, thee tuaj yeem ua rau nws tus kheej. Thermocouples nyob rau hauv qhov chaw cia ceeb toom rau cov neeg ua haujlwm ntawm qhov kub tsis txawv txav. Los ntawm txoj kev ceeb toom ntxov no, qhov hluav taws kub tuaj yeem raug zam, yog li tiv thaiv kev cuam tshuam loj rau tag nrho cov chaw thiab ib puag ncig. Tsis tas li ntawd, kev tswj xyuas qhov kub thiab txias tau lees paub los ntawm cov thermocouples pab kom tsis txhob muaj kev phom sij uas tuaj yeem ua rau tawg hauv cov chaw ua haujlwm thee uas muaj cov pa phem hauv qee qhov haujlwm.
Muaj qee qhov txiaj ntsig ntawm kev siv qee cov thermocouples hauv kev ua cov thee. Lawv yog qhov tsis tseem ceeb vim tias lawv qhov tseeb hauv cov ntawv thov kub kub, muaj zog hauv kev xav tau ib puag ncig, lub sijhawm ceev cov tshuaj tiv thaiv, thiab kev pab cuam txog kev nyab xeeb. Cov kev tiv thaiv nyob ntsiag to ntawm cov thee ua haujlwm, cov thermocouples no muab kev ua haujlwm zoo, nyab xeeb, ua haujlwm zoo uas yuav tsum muaj rau kev tsim hluav taws xob thiab lwm yam kev ua haujlwm ntawm cov thee.
