I-Rupsha 800MW Combined Cycle Power Plant Project (Khulna) iphrojekthi enkulu kunazo zonke ye-EPC yesizinda samandla enjini yegesi eyodwa e-Bangladesh. Itholakala eKhulna City, e-Bangladesh, le ndawo iqhele ngamakhilomitha angu-7.7 ukusuka edolobheni laseKhulna.
Umtshali-zimali nomnikazi yi-Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), kanti usonkontileka jikelele we-EPC uyinhlanganisela ye-Shanghai Electric Group Co., Ltd. (SEC) kanye ne-Italy Ansaldo (AEN), kanye ne-Fujian Yongfu Electric. I-Power Design Co., Ltd. (YONGFU) Yenhlolovo yephrojekthi kanye neyunithi yokuklama.Iphrojekthi yesiteshi samandla kagesi ongumjikelezo ongu-800MW ehlanganisiwe e-Bangladesh Rupusha ihlanganisa izinjini zegesi ezimbili ze-“F”-class (Alstom GT26), amajeneretha kagesi wegesi amabili, amabhoyela okushisa angcolile amabili, izinjini zesitimu esipholile ezimbili eziqondile kanye nezinjini ezimbili ezikhiqiza isitimu. Isikhungo sikagesi sisebenzisa igesi yemvelo njengophethiloli oyinhloko kanye ne-HSD yedizili enesivinini esikhulu njengowokugcina uphethiloli. Amandla esikhungo sikagesi athunyelwa ngaphandle kolayini namalophu aphindwe kabili angu-230kV futhi axhunywe esiteshini esincane esiseningizimu ye-PGCB National Grid Khulna.
Iphampu yamanzi ephakelayo ye-OTC yesiteshi samandla kagesi esiphehla umjikelezo ohlanganisiwe we-800MW e-Bangladesh Rupusha isetshenziselwa ukuhlinzeka ngamanzi okuqhubekayo kwi-OTC ye-gas turbine kanye nokuhlinzeka ngamanzi ashisayo ku-OTC desuperheater kanye nesinciphisi somfutho (bona Umfanekiso 3). Kunamayunithi amabili esewonke, iyunithi ngayinye ifakwe amaphampu amanzi okuphakelayo e-OTC angu-2 100%, eyodwa esebenzayo nenye ibekwe eceleni. Igama eliphakathi nendawo: Ukunikezwa kwamanzi kwe-OTC; PH inani: 9.2~9.6; ubulukhuni: 0mmol/l; conductivity: ≤ 0.3ms / cm; okuqukethwe kwe-oxygen: ≤ 7mg/l; i-iron ions: ≤ 20 mg / l; ion zethusi: ≤ 5mg/l; Iqukethe i-silicon dioxide: ≤ 20mg/l.
Ekusebenzeni komjikelezo ohlangene weyunithi, amanzi okuphakelayo asuka kubhayela wokushisa kukadoti (HRSG) angena ku-OTC enengcindezi ephezulu, futhi ukushisa okukhishwe umoya oshisayo okutholiwe kungena ohlelweni lokujikeleza kwamanzi esitimu.
Iphampu yamanzi okuphakelayo kwe-OTC iyadingeka ukuze ihlangabezane nezimo ezihlukahlukene zokusebenza ze-OTC ye-gas turbine. Uma iphampu egijimayo ihamba ngephutha, iphampu yokulinda ingafakwa ngokuzenzakalelayo ukuthi isebenze. Ukuze kuhlangatshezwane nezidingo ezikhethekile zokuqalisa, ukuvala shaqa kanye nezimo zokuhlola, kungenziwa mathupha esizeni, futhi kufakwe isixhumi esibonakalayo sokulawula kude se-DCS egumbini lokulawula iyunithi.
Amaphampu amanzi okuphakelayo ama-OTC angu-800MW esiteshini samandla omjikelezo ohlangene wamandla kagesi e-Rupsha, e-Bangladesh athengwe yi-Shanghai Electric Group Co., Ltd. (SEC) ngokubhida. Ngemuva kwemizuliswano eminingi yokuxhumana kwezobuchwepheshe, i-Q&A yevidiyo, nezingxoxo zebhizinisi, bagcina sebeyiqembu. Iphampu ye-SLDT yezigaba eziningi eyi-centrifugal eklanywe futhi yathuthukiswa imboni yakwa-Dalian isimemezele ibhidi yayo yokuwina.
Iphampu yamanzi ephakelayo ye-OTC isebenzisa i-API610-BB4 eneziphetho ezimbili esekela igobolondo elilodwa elihlukaniseke ngokuvundlile iphampu ye-centrifugal enezigaba eziningi eklanywe futhi yathuthukiswa isitshalo sase-Dalian se-Liancheng Group. Imodeli yayo yi-SLDT80-260D×9 yephampu ye-centrifugal enezigaba eziningi.
Iphampu yamanzi okuphakelayo kwe-OTC, ukusebenza kwale futha yesiteshi kuhlobene nokuphepha kwayo yonke idivayisi, futhi izidingo zokuphepha nokuzinza ziphezulu kakhulu.
Kumaphampu amanzi okuphakelayo e-OTC, into yokuqala okufanele icatshangelwe imvelo ethuthukisiwe, ukuvuthwa, ukuphepha nokuthembeka kwephampu, nokushintshana okujulile kobuchwepheshe, ukubonisana nophenyo kuyadingeka. Iphampu yamanzi okuphakelayo kwe-OTC iyisisetshenziswa esibalulekile sesiteshi samandla esiphehla umjikelezo wegesi engu-800MW. Kuphela ngokukhetha abahlinzeki abahle kakhulu kanye nomklamo othuthukisiwe kanye nobuchwepheshe bokukhiqiza lapho kungaqinisekiswa khona ukusebenza okuqhubekayo kwezisetshenziswa zikagesi, ukukhuliswa kwezithakazelo zezinkampani kanye nomjikelezo wesikhathi eside wesiteshi samandla kagesi ophehla ugesi ongu-800MW.
Ukubhida okuyimpumelelo kwephampu yamanzi e-OTC ye-Rupsha 800MW gas turbine edidiyelwe esiteshini samandla kagesi e-Bangladesh kukhombisa ukuthi iphampu yenkampani ye-OTC feedwater emkhakheni wokuphehla amandla aphehlwa ngegesi iye yaqashelwa ngokugcwele ngamakhasimende ngokuthuthuka kwayo okuphelele kwamandla, futhi yabuye yahlanganiswa. ubuholi benkampani kwezobuchwepheshe embonini. Thuthukisa ukuncintisana kwemakethe.
Ngaphezu kwalokho, uchungechunge lwe-SLDT BB4 iphampu ye-centrifugal enezigaba eziningi eklanywe futhi yathuthukiswa isitshalo sase-Dalian se-Liancheng Group isetshenziswe ngokulandelana kuphrojekthi yokupheka ye-Shanxi Lubao Group Co., Ltd. (izinga lokushisa lamanzi abilayo T=158℃), kanye ne-Cathay Zhongke Hlanza Iphampu yamanzi kabhoyela oshisayo (izinga lokushisa lamanzi abilayo T=120-130℃) namanye amaphrojekthi wobunjiniyela kuphrojekthi yokukhiqiza amandla ye-Energy Technology Co., Ltd.
Ngamafuphi, ngokusekelwe kumqondo wokuthuthukiswa okuluhlaza, inhlangano ecophelelayo, ukuphathwa kwe-lean, qhubeka nokuhlinzeka amakhasimende ngezinsizakalo ezisezingeni lokuqala, ukusebenza namakhasimende ukudala amandla ahlanzekile, aphansi, aphephile futhi asebenzayo, aqhubeke nokuthatha umgwaqo ophezulu. -ikhwalithi yokuthuthukiswa kwamandla, futhi uqhubeke nokudala amaphrojekthi ahlanzekile ahlanzekile, anekhabhoni ephansi yekhwalithi Kuwumgomo ongaguquki nenjongo yesitshalo saseDalian seLiancheng Group.
