Silicon carbide (SiC) ceramic nozzlestau dhau los ua cov khoom tseem ceeb hauv ntau hom kev lag luam, tshwj xeeb tshaj yog nyob rau hauv thaj chaw ntawm flue gas desulfurization (FGD). Cov nozzles tau ua tib zoo tsim los tiv thaiv cov xwm txheej huab cua thiab ua tau zoo rau cov cheeb tsam uas muaj qhov kub thiab txias thiab cov tshuaj corrosive ntau heev. Lawv cov khoom tshwj xeeb, suav nrog lub zog siab, hardness thiab hnav thiab corrosion kuj, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev txhim kho kev ua haujlwm ntawm cov nroj tsuag hluav taws xob thiab roj turbines.
Silicon carbide ceramic nozzles ua lub luag haujlwm tseem ceeb hauv cov txheej txheem desulfurization hauv cov nroj tsuag hluav taws xob. Lub luag haujlwm tseem ceeb ntawm cov nozzles yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam hniav, nws yog ib qho tseem ceeb rau kev txo qis sulfur dioxide). Lub siab kub tsis kam ntawm silicon carbide ua rau cov nozzles ua haujlwm zoo nyob rau hauv cov xwm txheej hnyav ntawm cov chaw tsim hluav taws xob. Los ntawm kev ua kom zoo ib yam ntawm cov desulfurization tus neeg sawv cev, cov nozzles txhim kho tag nrho cov desulfurization efficiency, yog li txo qhov emissions ntawm pa phem gases.
Lub durability ntawm silicon carbide nozzles yog lwm qhov zoo dua. Nyob rau hauv ib puag ncig uas cov ntaub ntawv ib txwm muaj peev xwm degrade sai vim yog corrosion los yog hnav, silicon carbide sawv tawm vim nws lub neej ua haujlwm ntev. Qhov kev ua haujlwm ntev no txhais tau tias tus nqi kho qis dua thiab qis dua rau cov chaw tsim hluav taws xob vim tias cov neeg ua haujlwm tuaj yeem tso siab rau cov nozzles txuas ntxiv mus rau lub sijhawm ntev dua. Rau cov chaw tsim hluav taws xob sib zog ua kom tau raws li cov kev cai nruj ib puag ncig, kev muaj peev xwm tswj tau kev ua haujlwm ncaj ncees nyob rau hauv cov xwm txheej nyuaj yog qhov tseem ceeb.
Tsis tas li ntawd, cov kev siv ntawm silicon carbide nozzles ntev tshaj li flue gas desulfurization. Hauv cov roj turbines, cov nozzles pab ntxuav cov roj ua ntej lawv nkag mus rau hauv lub turbine. Lub siab hardness thiab lub zog ntawm silicon carbide enables meej tswj cov roj ntws, xyuas kom tsawg impurities. Cov txheej txheem purification no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov roj turbines, vim nws pab tiv thaiv kev puas tsuaj thiab tswj cov qib kev ua tau zoo. Los ntawm kev siv silicon carbide nozzles, cov neeg ua haujlwm tuaj yeem txhim kho kev ntseeg tau thiab kev ua haujlwm ntawm cov roj turbine.
Lub versatility ntawm silicon carbide ceramic nozzles kuj tau tshwm sim nyob rau hauv lawv lub peev xwm ua hauj lwm nyob rau hauv ntau yam kev lag luam ib puag ncig. Ntxiv nrog rau kev tsim hluav taws xob thiab roj turbines, cov nozzles tseem tuaj yeem siv rau hauv kev ua tshuaj lom neeg, kev tswj cov khib nyiab thiab lwm yam kev lag luam uas xav tau cov ntaub ntawv ua tau zoo. Lawv cov tshuaj tiv thaiv ua rau lawv haum rau siv nyob rau hauv ib puag ncig uas muaj cov tshuaj corrosive, kom ntseeg tau tias lawv tuaj yeem tiv taus qhov nruj ntawm ntau yam kev lag luam.
Ntxiv rau lawv cov khoom siv kho tshuab thiab tshuaj lom neeg, silicon carbide nozzles kuj ua rau muaj kev ruaj ntseg ib puag ncig. Los ntawm kev txhim kho desulfurization efficiency thiab txo qis emissions, cov nozzles ua lub luag haujlwm tseem ceeb hauv kev pab kev lag luam ua raws li kev cai ib puag ncig. Raws li thoob ntiaj teb kev paub txog huab cua zoo thiab kev tswj hwm kev ua qias tuaj ntxiv, kev thov rau cov kev daws teeb meem zoo xws li silicon carbide ceramic nozzles yuav tsum loj hlob. Lawv lub peev xwm los txhawb kev ua haujlwm huv kom haum nrog lub hom phiaj dav dua ntawm kev txo cov kev cuam tshuam ib puag ncig ntawm kev lag luam.
Nyob rau hauv cov ntsiab lus, silicon carbide ceramic nozzles yog indispensable nyob rau hauv niaj hnub muaj kev siv, tshwj xeeb tshaj yog nyob rau hauv flue gas desulfurization thiab roj turbine lag luam. Lawv qhov tshwj xeeb siab zog, hardness, corrosion kuj thiab hnav kuj ua rau lawv zoo tagnrho rau kev txhim kho fais fab nroj tsuag efficiency thiab txo emissions. Raws li kev lag luam tseem ceeb ua kom muaj kev ruaj ntseg thiab ua raws li cov qauv ntawm ib puag ncig, lub luag haujlwm ntawm silicon carbide nozzles yuav ua rau muaj txiaj ntsig zoo dua, ua rau txoj hauv kev kom huv thiab ua haujlwm zoo dua.
