Thaum lub sijhawm ua haujlwm ntawm cov chaw tsim hluav taws xob thermal, cov khoom siv hnav thiab tsim kua muag yeej ib txwm yog qhov teeb meem tseem ceeb uas cuam tshuam rau kev ua haujlwm zoo thiab nce tus nqi txij nkawm. Cov siv txoj siv sia thiab cov kav dej tso thee ntawm lub kaw lus thauj thee, nrog rau cov khoom siv nyiaj txiag thiab cov cua sov ntawm lub kaw lus boiler, raug kev puas tsuaj ntev los ntawm cov ntaub ntawv thiab kev xeb kub siab, ua rau muaj kev hnav hnyav heev. Nyob rau xyoo tas los no, cov vuas ceramic alumina tau siv dav hauv kev tiv thaiv kev hnav hauv cov chaw tsim hluav taws xob vim lawv cov kev ua tau zoo tshaj plaws, ua tiav cov teebmeem tiv thaiv kev hnav zoo kawg nkaus thiab daws qhov teeb meem no tau zoo.
Qhov kev ua tau zoo heev ntawm cov vuas ceramic alumina yog vim lawv cov khoom siv tshwj xeeb. Alumina ceramics muaj qhov nyuaj heev, nrog Mohs hardness txog li 9, thib ob tsuas yog pob zeb diamond, thiab tuaj yeem tiv taus qhov kev puas tsuaj ntawm cov khoom siv. Lub caij no, nws kuj muaj kev tiv thaiv kev hnav zoo heev. Nws qhov kev tiv thaiv kev hnav yog 266 npaug ntawm cov hlau manganese thiab 171.5 npaug ntawm cov hlau cam khwb cia siab chromium, uas tuaj yeem ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua. Tsis tas li ntawd, cov vuas ceramic alumina kuj muaj kev tiv thaiv kub zoo heev thiab tuaj yeem ua haujlwm ruaj khov hauv qhov kub siab ntawm 1200 ℃, uas ua rau lawv ua tau zoo heev hauv kev siv tiv thaiv kev hnav rau cov khoom siv kub siab hauv cov chaw tsim hluav taws xob.
Hauv kev siv cov chaw tsim hluav taws xob, cov txheej txheem teeb tsa ntawm alumina ceramic ntawv yog yoog tau thiab ntau yam. Cov feem ntau suav nrog hom nplaum, hom inlay thiab hom vuam. Kev teeb tsa nplaum yog kom lo cov ntawv ceramic rau ntawm qhov chaw ntawm cov khoom siv los ntawm cov nplaum tshwj xeeb uas tiv taus kub thiab muaj zog siab. Txoj kev no yooj yim rau kev khiav lag luam thiab haum rau cov khoom uas muaj cov duab nyuaj. Kev teeb tsa inlaid suav nrog kev ua cov grooves ntawm qhov chaw ntawm cov khoom siv uas phim cov duab ntawm cov ntawv ceramic thiab embed cov ntawv ceramic rau hauv nws. Txoj kev no muaj cov txiaj ntsig zoo thiab haum rau cov khoom uas raug rau lub zog cuam tshuam ntau dua. Kev teeb tsa welded suav nrog kev vuam cov ntawv ceramic rau ntawm qhov chaw ntawm cov khoom siv los ntawm cov txheej txheem vuam tshwj xeeb. Nws muaj lub zog txuas siab thiab haum rau thaj chaw uas muaj kev hnav hnyav thiab cov xwm txheej ua haujlwm hnyav.
Piv txwv li, siv cov yeeb nkab thee ntawm lub chaw tsim hluav taws xob lub tshuab xa cov thee ua piv txwv. Ua ntej kev teeb tsa cov phaj alumina ceramic, vim muaj kev puas tsuaj ntawm cov thee, phab ntsa yeeb nkab ntawm cov yeeb nkab thee tau hnav hnyav heev, thiab nws yuav tsum tau hloov pauv txhua rau lub hlis. Qhov no tsis yog tsuas yog ua rau tus nqi txij nkawm nce ntxiv xwb tab sis kuj cuam tshuam rau kev tsim khoom ib txwm ntawm lub chaw tsim hluav taws xob. Tom qab siv cov nplaum ntawm cov phaj alumina ceramic, qhov kev tiv thaiv kev hnav ntawm cov yeeb nkab thee tau txhim kho zoo heev, lub voj voog hloov pauv tau ntev mus txog 3 txog 5 xyoos, txo qhov tsis ua haujlwm rau kev txij nkawm thiab txhim kho kev ua haujlwm zoo.
Daim ntawv thov ntawm alumina ceramic vuas hauv cov khoom xws li economizers thiab superheaters ntawm lub boiler system kuj tau ua tiav cov teebmeem tiv thaiv kev hnav zoo. Cov khoom no tau raug rau qhov kub thiab txias siab thiab cov hmoov av siab ntev, ua rau muaj teeb meem hnav thiab xeb. Los ntawm kev teeb tsa alumina ceramic vuas hauv txoj kev inlaid lossis welded, ib txheej tiv thaiv khov kho tau tsim, zoo tiv taus kev yaig thiab xeb ntawm cov hmoov av kub siab, txo qhov kev puas tsuaj ntawm cov khoom, thiab txhim kho kev ruaj khov thiab kev nyab xeeb ntawm kev ua haujlwm boiler.
Kev siv cov vuas ceramic alumina hauv cov chaw tsim hluav taws xob tsis yog tsuas yog ua kom cov khoom siv tiv thaiv kev hnav tsis zoo xwb tab sis kuj tseem muaj txiaj ntsig zoo rau kev lag luam. Kev txo qhov zaus ntawm kev saib xyuas thiab hloov khoom siv tau txo cov nqi kho thiab kev poob sijhawm. Kev ncua lub neej kev pabcuam ntawm cov khoom siv, txhim kho nws qhov kev ntseeg siab thiab kev ua haujlwm zoo, thiab muab kev lees paub zoo rau kev tsim khoom ruaj khov ntawm cov chaw tsim hluav taws xob. Nrog rau kev nce qib tas mus li ntawm thev naus laus zis, kev cia siab ntawm kev siv cov vuas ceramic alumina hauv cov chaw tsim hluav taws xob yuav dav dua, thiab lawv xav tias yuav ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, pab cov chaw tsim hluav taws xob ua tiav kev ua haujlwm zoo, ruaj khov thiab kev lag luam.
