Ngexesha lokusebenza kwezityalo zamandla obushushu, ukuguguleka kwezixhobo bekusoloko kuyingxaki ebalulekileyo echaphazela ukusebenza kakuhle kwemveliso kunye nokunyusa iindleko zokulungisa. Iirola zebhanti kunye neepayipi zokuwisa amalahle zenkqubo yokuhambisa amalahle, kunye ne-economizers kunye ne-superheaters zenkqubo yebhoyila, zichaphazeleka kukuguguleka kwexesha elide zizinto kunye nokugqwala okushushu kakhulu, okubangela ukuguguleka okukhulu kakhulu. Kwiminyaka yakutshanje, iithayile ze-alumina ceramic ziye zasetyenziswa kakhulu kwicandelo lokuguguleka kwizityalo zamandla ngenxa yokusebenza kwazo okugqwesileyo, zifezekisa iziphumo ezimangalisayo zokuguguleka kunye nokusombulula le ngxaki ngempumelelo.
Ukusebenza kakuhle kakhulu kokuchasana nokuguguleka kweethayile ze-alumina ceramic kuvela kwiimpawu zazo ezikhethekileyo zezinto. Ii-alumina ceramics zinobunzima obuphezulu kakhulu, zinobunzima be-Mohs obufikelela kwi-9, obulandela idayimani kuphela, kwaye zinokumelana nokukhukuliseka okukhulu kweesuntswana zezinto. Okwangoku, ikwanakho ukumelana nokuguguleka okuhle kakhulu. Ukumelana kwayo nokuguguleka kuphindwe ka-266 kunentsimbi ye-manganese kunye ne-171.5 kunentsimbi ephezulu ye-chromium, enokwandisa kakhulu ubomi benkonzo yezixhobo. Ukongeza, iithayile ze-alumina ceramic nazo zinokumelana okuphezulu kakhulu nobushushu kwaye zinokusebenza ngokuzinzileyo kwindawo enobushushu obuphezulu be-1200℃, nto leyo eyenza ukuba zisebenze ngokugqwesileyo kwizicelo zokulwa nokuguguleka kwezixhobo ezinobushushu obuphezulu kwizityalo zamandla.
Ekusetyenzisweni okusebenzayo kwezityalo zamandla, iindlela zokufakela amaphepha e-alumina ceramic ziyaguquguquka kwaye zahlukahlukene. Eziqhelekileyo ziquka uhlobo lokuncamathelisa, uhlobo lokufaka kunye nohlobo lokuwelda. Ukufakela okuncamathelisayo kukunamathela ngokuqinileyo amaphepha e-ceramic kumphezulu wesixhobo ngokusebenzisa izincamathelisi ezikhethekileyo ezimelana nobushushu obuphezulu nezinamandla aphezulu. Le ndlela kulula ukuyisebenzisa kwaye ifanelekile kwiindawo ezineemilo ezintsonkothileyo. Ukufakelwa okufakelweyo kubandakanya ukucubungula imingxunya kumphezulu wesixhobo ehambelana nomo wephepha le-ceramic kunye nokufaka iphepha le-ceramic kulo. Le ndlela inesiphumo esihle sokulungisa kwaye ifanelekile kwiindawo eziphantsi kwamandla amakhulu okubetha. Ukufakelwa okufakelweyo kubandakanya ukuwelda amaphepha e-ceramic kumphezulu wesixhobo ngenkqubo ekhethekileyo yokuwelda. Inamandla aphezulu oqhagamshelo kwaye ifanelekile kwiindawo ezinobunzima obukhulu kunye neemeko zokusebenza ezinzima.
Umzekelo, thabatha umbhobho welahle othontsizayo wenkqubo yokuhambisa amalahle yesikhululo samandla. Ngaphambi kokufakwa kweepleyiti ze-alumina ceramic, ngenxa yokukhukuliseka okuqhubekayo kwamasuntswana amalahle, udonga lombhobho welahle othontsizayo lwalugugile kakhulu, kwaye kwakufuneka lutshintshwe ngokomndilili rhoqo kwiinyanga ezintandathu. Oku akukonyusanga nje kuphela iindleko zokugcina kodwa kwachaphazela nemveliso eqhelekileyo yesikhululo samandla. Emva kokwamkela ukufakwa kwe-adhesive yeepleyiti ze-alumina ceramic, ukumelana nokuguguleka kombhobho welahle othontsizayo kuphuculwe kakhulu, umjikelo wokutshintshwa wongezwe ukuya kwiminyaka emi-3 ukuya kwemi-5, nto leyo eyanciphisa kakhulu ixesha lokungasebenzi kokugcinwa kunye nokuphucula ukusebenza kakuhle kwemveliso.
Ukusetyenziswa kweethayile ze-alumina ceramic kwiindawo ezifana ne-economizers kunye ne-superheaters zenkqubo ye-boiler nako kufikelele kwiziphumo ezilungileyo zokulwa nokuguguleka. Ezi ndawo ziye zavezwa kumaqondo obushushu aphezulu kunye namanqanaba aphezulu othuli ixesha elide, nto leyo ebangela iingxaki zokuguguleka nokugqwala. Ngokufaka iithayile ze-alumina ceramic ngendlela egqunyiweyo okanye edibeneyo, kwakheka umaleko oqinileyo okhuselayo, omelana ngempumelelo nokuguguleka nokugqwala kothuli olushushu kakhulu, ukunciphisa izinga lomonakalo weendawo, kunye nokuphucula uzinzo kunye nokhuseleko lokusebenza kwe-boiler.
Ukusetyenziswa kweethayile ze-alumina ceramic kwizikhululo zamandla akupheleli nje ekuphuculeni ukusebenza kwezixhobo ezichasene nokuguguleka kodwa kuzisa neenzuzo ezinkulu kwezoqoqosho. Ukunciphisa amaxesha okugcinwa nokutshintshwa kwezixhobo kuye kwehlisa iindleko zokugcinwa kunye nokulahlekelwa lixesha lokungasebenzi. Ukwandisa ubomi benkonzo yezixhobo, ukuphucula ukuthembeka kwazo kunye nokusebenza kakuhle, kunye nokubonelela ngesiqinisekiso esinamandla semveliso ezinzileyo yezikhululo zamandla. Ngokuqhubeka kweteknoloji, amathuba okusetyenziswa kweethayile ze-alumina ceramic kwizikhululo zamandla aya kuba banzi nangakumbi, kwaye kulindeleke ukuba zidlale indima ebalulekileyo kwiindawo ezininzi, zincede izikhululo zamandla zifezekise ukusebenza okusebenzayo, okuzinzileyo noqoqosho.
