Lub reflector yog tsim los cuam tshuam lub hnub ci mus rau lub concentrator los txhim kho lub zog hloov dua siab tshiab. Qhov zoo thermal conductivity ntawm alkaline refractory cib tuaj yeem ua kom cov txheej txheem hloov hluav taws xob ntawm lub hnub ci zog thiab ntxiv dag zog rau tag nrho cov kev ua tau zoo ntawm lub hnub ci hluav taws xob tsim hluav taws xob.
2. Daim ntawv thov ntawm alkaline magnesia cib nyob rau hauv cua zog tsim
Cua turbines hloov cua zog rau hauv tshuab hluav taws xob los ntawm kev sib hloov cov hniav, thiab tom qab ntawd hloov mus rau hauv hluav taws xob. Hauv cov txheej txheem no, lub combustion chamber yog ib qho ntawm cov khoom tseem ceeb. Nws yog siv los hlawv roj los tsim cov roj kub kub kom tsav lub turbine tig. Vim lub siab kub ntawm cov roj hauv lub turbine, cov khoom siv refractory yuav tsum muaj peev xwm tiv taus qhov kub thiab txias thiab tswj cov qauv kev ruaj ntseg los xyuas kom muaj kev nyab xeeb ntawm lub turbine. Nyob rau hauv lub high-temperature Cheebtsam ntawm cua turbines, xws li tshav kub exchangers thiab tso ducts, high-temperature resistant refractory cov ntaub ntawv kuj yuav tsum tau los xyuas kom meej lub ruaj khov ua hauj lwm ntawm lub system. Qhov zoo thermal conductivity ntawm alkaline magnesia refractory cib ua rau nws ua kom ceev cov cua kub ntawm cov roj kub kub, uas yuav pab tswj kom muaj qhov kub thiab txias hauv qhov system thiab txhim kho kev siv hluav taws xob.
3. Daim ntawv thov ntawm alkaline magnesia cib hauv kev lag luam hydrogen zog
Hauv kev lag luam hydrogen zog, qhov kub-kub reactor yog cov cuab yeej tseem ceeb siv los ua kom tiav cov txheej txheem ntawm kev tsim cov hydrogen xws li chav hloov pauv cov tshuaj tiv thaiv thiab methane hloov pauv cov tshuaj tiv thaiv. Basic magnesite refractory bricks tau dav siv nyob rau hauv hydrogen zog kev lag luam vim lawv zoo heev kub-kub stability thiab corrosion kuj. Ua ntej ntawm tag nrho cov, magnesium refractory cib tuaj yeem tiv taus kev ua haujlwm ntev hauv qhov chaw kub kub, tswj lub cev thiab tshuaj lom neeg ruaj khov, thiab ua kom lub cev ua haujlwm ntawm lub reactor. Qhov thib ob, qhov yooj yim magnesite refractory cib tuaj yeem tiv thaiv kev yaig ntawm cov roj corrosive xws li hydrogen thiab dej vapor, ncua kev pab cuam lub neej ntawm cov cuab yeej, thiab txo cov nqi tu. Nyob rau hauv cov txheej txheem ntawm hydrogen ntau lawm, sab hauv ntawm lub reactor yuav tsum tau tiv thaiv ib tug high-temperature thiab high-pressure ua hauj lwm ib puag ncig, thiab yuav tsum tau tswj kom zoo thermal conductivity los xyuas kom meej lub efficiency ntawm cov tshuaj tiv thaiv txheej txheem. Magnesia alkaline refractory cib muaj cov thermal conductivity zoo, tuaj yeem hloov cov cua sov mus rau tag nrho cov reactor, tswj qhov kub thiab txias, thiab txhim kho cov tshuaj tiv thaiv thiab kev ua haujlwm zoo.
4. Daim ntawv thov ntawm cov txheej txheem magnesia refractory cib hauv biomass zog
Biomass zog yog lub zog tauj dua tshiab uas siv cov khoom siv biomass xws li ntoo thiab straw rau lub zog hloov pauv, suav nrog biomass combustion, gasification, fermentation thiab lwm yam txheej txheem. Nyob rau hauv kev tsim thiab kev siv ntawm biomass zog, alkaline magnesia refractory firebricks feem ntau yog siv rau hauv cov qauv tsim ntawm biomass combustion boilers los yog biomass gasification khoom. Txij li thaum kub-kub combustion gas tsim thaum lub sij hawm biomass combustion muaj siab xav tau rau cov khoom siv sab hauv ntawm cov khoom, cov ntaub ntawv refractory yog xav tau los tsim lub cub tawg thiab cov qauv sab hauv ntawm lub boiler. Basic magnesia yooj yim refractory bricks tau dav siv nyob rau hauv biomass combustion boilers vim lawv zoo kub-kub stability thiab corrosion kuj. Lawv tuaj yeem tiv taus qhov cuam tshuam ntawm qhov kub thiab txias combustion gases thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv. Hauv cov khoom siv biomass gasification, cov khoom siv refractory kuj tseem xav tau los tsim cov qauv sab hauv ntawm lub reactor kom tiv taus qhov yaig ntawm qhov kub thiab txias ib puag ncig thiab corrosive gases. magnesium refractory bricks tau siv dav hauv cov khoom siv biomass gasification vim lawv qhov kub thiab txias tsis kam thiab corrosion kuj, uas tuaj yeem ua haujlwm ruaj khov thiab ua haujlwm zoo ntawm cov khoom siv.
