Ii-nozzles ze-silicon carbide ceramic zidlala indima ebalulekileyo kwinkqubo yokukhupha i-sulfurization kwizityalo zamandla. Umsebenzi ophambili wale milomo kukukhuthaza ukutshiza okufanayo kwe-arhente yokukhupha i-sulfurization, nto leyo ibalulekileyo ekunciphiseni ukukhutshwa kwe-sulfur dioxide (SO2) kwiigesi ze-flue. Ukumelana nobushushu obuphezulu kwe-silicon carbide kwenza ezi nozzles zisebenze ngokufanelekileyo phantsi kweemeko ezinzima eziqhelekileyo kwiindawo zokuvelisa umbane. Ngokuqinisekisa ukusasazwa okufanayo kwe-arhente yokukhupha i-sulfurization, ezi nozzles ziphucula kakhulu ukusebenza kakuhle kwe-desulfurization iyonke, ngaloo ndlela zinciphisa kakhulu ukukhutshwa kweegesi ezingcolisayo.
Ukuqina kwee-nozzles ze-silicon carbide yenye inzuzo ephambili. Kwiindawo apho izinto zemveli zinokonakala ngokukhawuleza ngenxa yokugqwala okanye ukuguguleka, i-silicon carbide iyabonakala ngenxa yobomi bayo obude benkonzo. Oku kuhlala ixesha elide kuthetha ukuba iindleko zokugcina ziphantsi kwaye ixesha lokungasebenzi kakuhle kwezityalo zamandla lincinci kuba abaqhubi banokuthembela kwezi nozzles ukuba ziqhubeke nokusebenza ixesha elide. Kwizityalo zamandla ezizama ukuhlangabezana nemigaqo engqongqo yokusingqongileyo, ukukwazi ukugcina ingqibelelo yokusebenza phantsi kweemeko ezinzima kubalulekile.
Ngaphezu koko, ukusetyenziswa kwee-nozzles ze-silicon carbide kudlulela ngaphaya kokususwa kwe-flue gas desulfurization. Kwii-turbines zegesi, ezi nozzles zinceda ekucoceni iigesi ngaphambi kokuba zingene kwi-turbine. Ubunzima obuphezulu kunye namandla e-silicon carbide kwenza ulawulo oluchanekileyo lokuhamba kwegesi, kuqinisekisa ukungcola okuncinci. Le nkqubo yokucoca ibalulekile ekusebenzeni kakuhle kwee-turbines zegesi, njengoko inceda ekuthinteleni umonakalo kunye nokugcina amanqanaba okusebenza afanelekileyo. Ngokusebenzisa ii-nozzles ze-silicon carbide, abaqhubi banokuphucula ukuthembeka kunye nokusebenza kakuhle kweenkqubo ze-turbine zegesi.
Ukuguquguquka kwee-nozzles ze-silicon carbide ceramic kubonakala nakwikhono lazo lokusebenza kwiindawo ezahlukeneyo zoshishino. Ukongeza ekuveliseni umbane kunye nee-turbines zegesi, ezi nozzles zingasetyenziswa nasekucubungulweni kweekhemikhali, ulawulo lwenkunkuma kunye nezinye iindawo ezifuna izixhobo zokusebenza okuphezulu. Ukumelana kwazo neekhemikhali kuzenza zilungele ukusetyenziswa kwiindawo apho kukho izinto ezirhabaxa, ukuqinisekisa ukuba ziyakwazi ukumelana nobunzima beenkqubo ezahlukeneyo zoshishino.
Ukongeza kwiipropati zazo zoomatshini nezekhemikhali, ii-nozzles ze-silicon carbide nazo zinegalelo ekuzinzeni kwendalo. Ngokuphucula ukusebenza kakuhle kwe-desulfurization kunye nokunciphisa ukukhutshwa komoya, ezi nozzles zidlala indima ebalulekileyo ekuncedeni ishishini ukuba lithobele imithetho yokusingqongileyo. Njengoko ulwazi lwehlabathi jikelele ngomgangatho womoya kunye nolawulo longcoliseko luqhubeka lusanda, kulindeleke ukuba imfuno yezisombululo ezisebenzayo ezifana nee-nozzles ze-ceramic ze-silicon carbide kulindeleke ukuba ikhule. Amandla azo okukhuthaza imisebenzi ecocekileyo ahambelana nenjongo ebanzi yokunciphisa impembelelo yokusingqongileyo yemisebenzi yemizi-mveliso.
Ngamafutshane, ii-nozzles ze-silicon carbide ceramic zibaluleke kakhulu kwizicelo zanamhlanje zoshishino, ingakumbi kwi-flue gas desulfurization kunye nokusebenza kwe-gas turbine. Amandla azo aphezulu, ubulukhuni, ukumelana nokugqwala kunye nokumelana nokuguguleka kuzenza zibe zilungele ukuphucula ukusebenza kakuhle kwezityalo zamandla kunye nokunciphisa ukukhutshwa komoya. Njengoko ishishini liqhubeka nokubeka phambili uzinzo kwaye lihambelana nemigangatho yokusingqongileyo, indima yee-nozzles ze-silicon carbide ngokuqinisekileyo iya kuba yinto ebalaseleyo, ivule indlela yeenkqubo zoshishino ezicocekileyo nezisebenzayo.
