Silicon carbide (SiC) ceramic nozzlestau dhau los ua cov khoom tseem ceeb hauv ntau yam kev siv hauv kev lag luam, tshwj xeeb tshaj yog hauv kev ua haujlwm ntawm flue gas desulfurization (FGD). Cov nozzles no tau tsim los kom tiv taus cov xwm txheej hnyav thiab zoo rau cov chaw uas muaj qhov kub thiab txias siab thiab cov tshuaj corrosive. Lawv cov yam ntxwv tshwj xeeb, suav nrog lub zog siab, tawv thiab hnav thiab tiv taus corrosion, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev txhim kho kev ua haujlwm ntawm cov chaw tsim hluav taws xob thiab cov roj turbines.
Cov nozzles ua los ntawm silicon carbide ceramic ua lub luag haujlwm tseem ceeb hauv cov txheej txheem desulfurization hauv cov chaw tsim hluav taws xob. Lub luag haujlwm tseem ceeb ntawm cov nozzles no yog txhawb kev txau cov tshuaj desulfurization sib npaug, uas yog qhov tseem ceeb rau kev txo cov pa roj sulfur dioxide (SO2) hauv cov pa roj flue. Qhov kub siab ntawm silicon carbide ua rau cov nozzles no ua haujlwm tau zoo nyob rau hauv cov xwm txheej hnyav uas feem ntau yog cov chaw tsim hluav taws xob. Los ntawm kev ua kom muaj kev faib tawm ntawm cov neeg sawv cev desulfurization sib npaug, cov nozzles no txhim kho qhov kev ua haujlwm desulfurization tag nrho, yog li txo qis cov pa roj uas ua rau muaj kuab paug.
Qhov ruaj khov ntawm cov silicon carbide nozzles yog lwm qhov zoo tseem ceeb. Hauv cov chaw uas cov khoom siv ib txwm muaj peev xwm lwj sai vim yog xeb lossis hnav, silicon carbide sawv tawm vim nws lub neej ua haujlwm ntev. Qhov ruaj khov no txhais tau tias cov nqi kho qis dua thiab lub sijhawm tsis ua haujlwm rau cov chaw tsim hluav taws xob tsawg dua vim tias cov neeg ua haujlwm tuaj yeem cia siab rau cov nozzles no kom txuas ntxiv ua haujlwm rau lub sijhawm ntev dua. Rau cov chaw tsim hluav taws xob uas siv zog ua raws li cov cai ib puag ncig nruj, lub peev xwm los tswj kev ua haujlwm zoo hauv qab cov xwm txheej nyuaj yog qhov tseem ceeb.
Ntxiv mus, daim ntawv thov ntawm silicon carbide nozzles nthuav dav tshaj qhov flue roj desulfurization. Hauv cov roj turbines, cov nozzles no pab ntxuav cov pa roj ua ntej lawv nkag mus rau hauv lub turbine. Qhov siab hardness thiab lub zog ntawm silicon carbide ua rau muaj kev tswj hwm qhov tseeb ntawm cov roj ntws, kom ntseeg tau tias muaj tsawg kawg nkaus impurities. Cov txheej txheem ntxuav 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 tshaj plaws. Los ntawm kev siv silicon carbide nozzles, cov neeg teb xov tooj tuaj yeem txhim kho kev ntseeg siab thiab kev ua haujlwm ntawm cov roj turbine systems.
Qhov ua tau ntau yam ntawm cov silicon carbide ceramic nozzles kuj pom tseeb hauv lawv lub peev xwm los ua haujlwm hauv ntau qhov chaw ua haujlwm. Ntxiv rau kev tsim hluav taws xob thiab cov roj turbines, cov nozzles no kuj tseem siv tau rau hauv kev ua tshuaj lom neeg, kev tswj hwm pov tseg thiab lwm yam teb uas xav tau cov ntaub ntawv ua tau zoo. Lawv cov tshuaj tiv thaiv ua rau lawv tsim nyog rau kev siv hauv cov chaw uas muaj cov tshuaj corrosive, kom ntseeg tau tias lawv tuaj yeem tiv taus qhov nyuaj ntawm ntau yam txheej txheem kev lag luam.
Ntxiv rau lawv cov khoom siv kho tshuab thiab tshuaj lom neeg, cov nozzles silicon carbide kuj tseem pab txhawb rau kev ruaj khov ntawm ib puag ncig. Los ntawm kev txhim kho kev ua haujlwm desulfurization thiab txo cov pa phem, cov nozzles no ua lub luag haujlwm tseem ceeb hauv kev pab kev lag luam ua raws li cov cai ib puag ncig. Raws li kev paub thoob ntiaj teb txog kev ua pa zoo thiab kev tswj hwm kev ua qias tuaj txuas ntxiv mus, qhov kev thov rau cov kev daws teeb meem zoo xws li silicon carbide ceramic nozzles yuav loj hlob. Lawv lub peev xwm los txhawb kev ua haujlwm huv si sib haum nrog lub hom phiaj dav dua ntawm kev txo qhov cuam tshuam rau ib puag ncig ntawm kev ua haujlwm hauv kev lag luam.
Hauv kev xaus lus, cov silicon carbide ceramic nozzles yog qhov tseem ceeb hauv kev siv niaj hnub no, tshwj xeeb tshaj yog hauv flue gas desulfurization thiab kev ua haujlwm ntawm lub turbine roj. Lawv lub zog siab, qhov nyuaj, kev tiv thaiv corrosion thiab kev tiv thaiv hnav ua rau lawv zoo tagnrho rau kev txhim kho kev ua haujlwm ntawm lub zog fais fab thiab txo cov pa phem. Thaum kev lag luam txuas ntxiv muab qhov tseem ceeb rau kev ruaj khov thiab ua raws li cov qauv ib puag ncig, lub luag haujlwm ntawm silicon carbide nozzles yuav tsis muaj qhov tsis ntseeg tias yuav dhau los ua qhov tseem ceeb dua, paving txoj hauv kev rau cov txheej txheem kev lag luam huv dua thiab ua haujlwm tau zoo dua.
