Ulusu lwe-oxide lwe-supercritical circulating circulating fluidized bed boiler lubhekiselele kwi-oxide yesikhumba sobunzima obuthile obuyilwe emva kokuba ifilimu ye-oxidation iyancipha ngokuthe ngcembe emva kokuba ibhoyila isebenze ixesha elide, kwaye kuhlala kukho umahluko omkhulu kwi-coefficient yokwandiswa phakathi kwesikhumba se-oxide kunye ne-oxidation. umbhobho wentsimbi.Emva kokuba ibhoyili ivaliwe ukupholisa, isikhumba se-oxide siya kuwa, esiya kubangela ukuvaleka kombhobho wokufudumala.Ngaphezu koko, isixa esikhulu somlinganiselo we-oxide uya kuqokelelana emva kokuwa, okuya kukhokelela ekunciphiseni okanye ekuphazamisekeni komthamo womphunga kudonga lwetyhubhu yendawo yokufudumeza kunye nokuwohloka komphumo wokupholisa umphunga kumbhobho, oya kukhokelela ngokuthe ngqo. ukuya kudonga lwetyhubhu olugqithisiweyo okanye ukuqhuma kwetyhubhu.Ngokuqhelekileyo, ukwenzela ukukhusela isikhumba se-oxide ekuweni, amanyathelo afanelekileyo aya kuthathwa ekuyilweni, ukuvelisa, ukufakela kunye nokusebenza.Ngokukodwa:
1.Ngethuba loyilo olupheleleyo lwebhoyili, iindawo zokulinganisa ubushushu bodonga lokuphambuka kwe-thermal kufuneka zincitshiswe kangangoko kunokwenzeka, kwaye iindawo zokulinganisa ziya kuhlolwa rhoqo ukuze kuqinisekiswe ukuchaneka komlinganiselo wokushisa eludongeni.Ngenxa yokuphambuka kwe-thermal yendawo yokufudumala, ukushisa kwe-steam yendawo yokufudumala kuya kulawulwa ngokweqondo lokushisa elivumelekileyo letsimbi.Ubushushu bensimbi buya kulawulwa ngokungqongqo ngexesha lokusebenza ukuze kuqinisekiswe ukuba akukho overheating eyenzekayo.
2.Ukukhethwa kwemibhobho yendawo yokufudumeza ubushushu obuphezulu kuya kuqwalaselwa ngokufanelekileyo ngokwemida yokumelana ne-oxidation yobushushu obuphezulu.Kwiheater yeplaten, iheater ephambili kunye neendawo zokufudumeza zokugqibela zokufudumeza, i-SA213-TP347HFG kunye ne-SUPER304H zingasetyenziswa njengezixhobo.
3.Ukunyuka kwe-enthalpy, ukuchasa ukuhla kunye ne-inlet kunye ne-outlet yeefom ze-superheaters kuwo onke amanqanaba ziya kuyilwa ngokufanelekileyo ukulawula nokunciphisa ukutenxa kokuhamba.
4.I-hanger iya kuyilwa ngokufanelekileyo ukuqinisekisa umda owaneleyo, kwaye i-hanger enye iya kwaliwa.Ukufuduswa kwesixhobo sokuxhoma kwimeko ebandayo kuthathwa njenge-40% ~ 60% yaloo meko eshushu, ukuze umphezulu wokufudumeza weplaten ube ngathi ukwimo ebandayo ukunyusa ukuxhathisa ukonakala.
5.Qinisekisa ukwandiswa okukhululekileyo kwendawo yokufudumeza yeplaten.Kwindawo apho indawo yokufudumeza kweplaten idlula eludongeni, idibansi yokwandiswa kwesinyithi kunye nesakhiwo esifanelekileyo siya kusetyenziswa.Ngelo xesha, ulwakhiwo lwe-elbow oluphuculweyo luyamkelwa kwindawo yokuphuma kwendawo yokufudumeza yeplaten ukunyusa ukuguquguquka kweplaten kunye nokuphelisa ukuguqulwa okubangelwa ukwanda okuvaliweyo.
6.Ngexesha lokusebenza, amanzi ashushu kunye nokuvuthela kwesoot kuya kusetyenziswa ngokuthe gqolo ngokuhambelana neendlela eziyilelweyo zokuqalisa kunye nokuvalwa, utshintsho lomthwalo kunye nenqanaba lokutshintsha lobushushu, ukuze kuncitshiswe ukutenxa kwe-thermal, kuthintelwe ukutshisa kakhulu kunye nokutshintsha kweqondo lobushushu ngequbuliso, kunye nokomeleza ukujongwa komphunga kunye namanzi. ;Ukupholisa umoya okunyanzeliswayo kunqatshelwe ngokungqongqo kwiibhoyili ezineengxaki zesikali emva kokuvalwa.
7.Kwinkqubo yokuqalisa, ukuvala kunye nokutshintsha umthwalo, zama ukunqanda ukuguquguquka kweqondo lobushushu kunye nesantya sokutshintsha kobushushu bomphezulu wokufudumeza, kwaye ucothise ukuxobuka kwesikhumba se-oxide.
8.Ngethuba lokugcinwa, umtshini wesikhumba se-oxide uya kusetyenziselwa ukukhangela isikhumba se-oxide se-superheater kunye ne-reheater, kwaye ubomi benkonzo yeepayipi buya kuvavanywa kwaye imibhobho ene-oxidation enzima iya kutshintshwa ngexesha.
9.Ukuqinisa ukuhlolwa kwendawo yokufudumala kunye nentloko, kwaye uqinisekise ukuba ngaphakathi kwendawo yokufudumala icocekile kwaye ayinayo inkunkuma.Ukusuka kolona setyenziso lwebhoyila yebhedi ejikeleziswa kakhulu ejikelezayo ngoku, ingxaki yayo yesikali incinci kakhulu kunaleyo yebhoyila yamalahle ediliziweyo, ekwaluncedo olukhulu lwebhoyila yebhedi ejikelezayo.
Kukho izizathu ezibini eziphambili zokuwa kwesikali kwindawo yobushushu obuphezulu bebhoyila yebhedi ejikelezayo.Enye kukuba isikali sifikelela kubukhulu obuthile;Enye iqondo eliqhelekileyo, elikhulu kunye neliphezulu lokutshintsha kobushushu.Ngamaxesha aqhelekileyo, kufuneka sijonge kwangexesha ukulungiswa kwebhoyila kwaye sijonge rhoqo ukuba kukho iingozi ezifihlakeleyo kwibhoyila.
