Isikhumba se-oxide se-supercritical circulating fluidized bed boiler sibhekisela esikhumbeni se-oxide sogqinsi oluthile olwakhiwe ngemva kokuba ifilimu ye-oxidation iyancipha kancane kancane ngemva kokuba i-boiler isebenze isikhathi eside, futhi kuvame ukuba nomehluko omkhulu ku-coefficient yokwandisa phakathi kwesikhumba se-oxide kanye nesikhumba. i-substrate yepayipi yensimbi.Ngemuva kokuthi i-boiler ivaliwe ukupholisa, isikhumba se-oxide sizowa, okuzoholela ekuvinjweni kwepayipi yendawo yokushisa.Ngaphezu kwalokho, inani elikhulu lesikali se-oxide lizoqoqwa ngemva kokuwa, okuzoholela ekunciphiseni noma ekuphazamisekeni kwevolumu ye-steam odongeni lweshubhu yendawo yokushisa kanye nokuwohloka komphumela wokupholisa umusi epayipini, okuzoholela ngokuqondile. ekushiseni ngokweqile kodonga lweshubhu noma ukuqhuma kweshubhu.Ngokuvamile, ukuze kuvikelwe isikhumba se-oxide ekuweni, izinyathelo ezinhle zizothathwa ekwakhiweni, ekukhiqizeni, ekufakeni nasekusebenzeni.Ngokuqondile:
1.Phakathi nomklamo jikelele webhayela, izindawo zokulinganisa izinga lokushisa odongeni lokuchezuka kokushisa kufanele zincishiswe ngangokunokwenzeka, futhi amaphuzu okulinganisa kufanele ahlolwe njalo ukuze kuqinisekiswe ukunemba kwesilinganiso sokushisa odongeni.Ngenxa yokuphambuka okushisayo kwendawo yokushisa, izinga lokushisa le-steam lendawo yokushisa lizolawulwa ngokuvumelana nezinga lokushisa elivumelekile lensimbi.Izinga lokushisa lensimbi kufanele lilawulwe ngokuqinile ngesikhathi sokusebenza ukuze kuqinisekiswe ukuthi akukho ukushisa okweqile okwenzekayo.
2.Ukukhethwa kwamapayipi angaphezulu okushisa okushisa kufanele kucatshangelwe ngokunengqondo ngokwesilinganiso sokumelana ne-oxidation lokushisa eliphezulu.Ku-platen superheater, i-superheater eyinhloko kanye nezindawo zokugcina zokufudumeza kabusha, i-SA213-TP347HFG kanye ne-SUPER304H ingasetshenziswa njengezinto zokwakha.
3.Ukwanda kwe-enthalpy, ukwehla kokumelana kanye nezinhlobo ze-inlet ne-outlet zama-superheaters kuwo wonke amazinga azoklanywa ngendlela enengqondo ukulawula nokunciphisa ukuchezuka kokugeleza.
4.I-hanger izoklanywa ngokunengqondo ukuze kuqinisekiswe imaji eyanele, futhi isiphanyeko esisodwa sizonqatshwa.Ukugudluzwa kwedivayisi elengayo esimweni esibandayo kuthathwa njengo-40% ~60% waleyo esesimweni esishisayo, ukuze indawo yokushisisa eyi-platen ikwazi ukwenziwa sengathi isesimweni esibandayo ukuze kwandiswe ukumelana nokuguquguquka.
5.Qinisekisa ukunwetshwa kwamahhala kwendawo yokushisisa ye-platen.Endaweni lapho indawo yokushisisa edlula odongeni, indawo yokunweba yensimbi enesakhiwo esiphusile izosetshenziswa.Ngasikhathi sinye, ukwakheka kwendololwane okuthuthukisiwe kwamukelwa lapho kuphuma indawo yokushisa ye-platen ukuze kwandiswe ukuguquguquka kwe-platen futhi kuqedwe ukuguqulwa okubangelwa ukunwetshwa okuvinjiwe.
6.Ngesikhathi sokusebenza, amanzi ashisa kakhulu kanye nokuvunguza kwensisi kufanele kusetshenziswe kancane kancane ngokuhambisana nezindlela eziklanyelwe ukuqalisa nokuvala, ukushintsha komthwalo kanye nezinga lokushisa lokushintsha izinga lokushisa, ukuze kuncishiswe ukuchezuka kokushisa, ukugwema ukushisa ngokweqile nokushintsha okungazelelwe kwezinga lokushisa, futhi kuqinise ukugadwa kwesitimu namanzi. ;Ukupholisa umoya ngempoqo akuvunyelwe ngokuphelele kuma-boilers anezinkinga zesikali ngemuva kokuvala.
7.Enqubweni yokuqalisa, ukuvala shaqa kanye noshintsho lomthwalo, zama ukunqanda ukuguquguquka kwezinga lokushisa ngezikhathi ezithile kanye nezinga lokushisa elishintshayo endaweni yokushisa, futhi wehlise ijubane ukuxebuka kwesikhumba se-oxide.
8.Ngesikhathi sokulungiswa, umtshina wesikhumba se-oxide uzosetshenziswa ukuthola isikhumba se-oxide se-superheater kanye ne-heater, futhi impilo yesevisi yamapayipi izohlolwa futhi amapayipi ane-oxidation enamandla azoshintshwa ngesikhathi.
9.Qinisa ukuhlolwa kwendawo yokushisisa kanye nesihloko, futhi uqinisekise ukuthi ingaphakathi lendawo yokushisisa ihlanzekile futhi ayinayo imfucumfucu.Kusukela ekusetshenzisweni kwangempela kukabhayela wombhede ogelezayo ojikelezayo ogelezayo njengamanje, inkinga yawo yesilinganiso ayibi kakhulu kunaleyo yebhayela yamalahle egayiwe, nayo eyinzuzo enkulu yebhayela yombhede ojikelezayo omanzi.
Kunezizathu ezimbili eziyinhloko zokuwa kwesikali endaweni yokushisisa enezinga eliphezulu lokushisa kubhayela wombhede ojikelezayo omanzi.Esinye siwukuthi isikali sifinyelela ubukhulu obuthile;Okunye izinga lokushisa elivamile, elikhulu neliphezulu.Ngezikhathi ezijwayelekile, kufanele sihlole ngesikhathi esifanele ukulungiswa kokusebenza kwe-boiler futhi sihlole njalo ukuthi zikhona yini izingozi ezifihliwe ku-boiler.
