Iphrojekthi Yesitshalo Sikagesi Esihlanganisiwe iRupsha 800MW (Khulna) iyiphrojekthi enkulu kunazo zonke yesitshalo sikagesi esisodwa i-EPC eBangladesh. Itholakala eKhulna City, eBangladesh, indawo ingamakhilomitha angu-7.7 kuphela ukusuka edolobheni laseKhulna.
Umtshali-zimali kanye nomnikazi yiBangladesh Northwest Power Generation Co., Ltd. (NWPGCL), kanti inkontileka jikelele ye-EPC iyinhlanganisela yeShanghai Electric Group Co., Ltd. (SEC) kanye ne-Ansaldo (AEN) yase-Italy, kanye neFujian Yongfu Electric Power Design Co., Ltd. (YONGFU) Yeyunithi yokuhlola nokuklama iphrojekthi.Iphrojekthi yesiteshi samandla kagesi esihlanganisiwe se-turbine yegesi engu-800MW eBangladesh iRupusha ihlanganisa ama-turbine amabili egesi e-“F” (Alstom GT26), ama-generator amabili e-turbine yegesi, ama-boiler amabili okushisa angcolile, ama-turbine amabili omusi apholile emoyeni kanye nama-generator amabili e-turbine ye-steam. Isitshalo samandla sisebenzisa igesi yemvelo njengophethiloli oyinhloko kanye ne-HSD yedizili yesivinini esiphezulu njengophethiloli wokusekela. Amandla esitshalo samandla athunyelwa ngaphandle komugqa ngezihibe ezimbili ezingama-230kV futhi axhunywe esiteshini esincane esiseningizimu se-PGCB National Grid Khulna.
Iphampu yamanzi e-OTC yesiteshi samandla esihlanganisiwe se-turbine yegesi esingu-800MW eBangladesh i-Rupusha isetshenziselwa ukuphakelwa kwamanzi okuqhubekayo kwi-OTC ye-turbine yegesi kanye nokuhlinzeka ngamanzi okususa ukushisa kwi-OTC desuperheater kanye ne-pressure reducer (bheka Umfanekiso 3). Kunamayunithi amabili esewonke, iyunithi ngayinye ifakwe amaphampu amanzi e-OTC angu-2 angu-100%, elinye lisebenza kanti elinye lilindile. Igama eliphakathi lokulethwa: Ukuphakelwa kwamanzi e-OTC; Inani le-PH: 9.2~9.6; ubulukhuni: 0mmol/l; ukuqhuba: ≤ 0.3ms/cm; okuqukethwe yi-oxygen: ≤ 7mg/l; ama-ion ensimbi: ≤ 20 mg/l; ama-ion ethusi: ≤ 5mg/l; Iqukethe i-silicon dioxide: ≤ 20mg/l.
Ekusebenzeni komjikelezo ohlangene weyunithi, amanzi okuhambisa amanzi avela ku-waste heat boiler (HRSG) high-pressure economizer angena ku-OTC high-pressure, kanti ukushisa okukhishwa umoya oshisayo otholiwe kungena ohlelweni lokujikeleza kwamanzi anomusi.
Iphampu yamanzi okuphakelwa yi-OTC iyadingeka ukuze ihlangabezane nezimo zokusebenza ezahlukahlukene ze-OTC ye-turbine yegesi. Uma iphampu esebenzayo iphuka ngengozi, iphampu yokulinda ingasetshenziswa ngokuzenzakalelayo. Ukuze ihlangabezane nezidingo ezikhethekile zezimo zokuqalisa, ukuvala kanye nokuhlola, ingasebenza ngesandla endaweni, futhi ifakwe isikhombimsebenzisi sokulawula kude se-DCS egumbini lokulawula iyunithi.
Amaphampu amane amanzi e-OTC esiteshini samandla kagesi esihlanganisiwe se-turbine yegesi esingu-800MW eRupsha, eBangladesh athengwe yiShanghai Electric Group Co., Ltd. (SEC) ngokubhida. Ngemva kwemijikelezo eminingi yokuxhumana kwezobuchwepheshe, imibuzo nezimpendulo zevidiyo, kanye nezingxoxo zebhizinisi, ekugcineni aba yiqembu. Iphampu ye-centrifugal ye-SLDT enezigaba eziningi eklanywe futhi yathuthukiswa yisitshalo saseDalian imemezele ibhidi layo eliwinile.
Iphampu yamanzi e-OTC isebenzisa iphampu ye-API610-BB4 enezinhlangothi ezimbili esekela i-single-shell ehlukanisiwe nge-radially evundlile enezigaba eziningi eklanywe futhi yathuthukiswa yisitshalo saseDalian seLiancheng Group. Imodeli yayo yiphampu ye-SLDT80-260D×9 enezigaba eziningi.
Iphampu yamanzi ephakelwa yi-OTC, ukusebenza kwale phampu yesiteshi kuhlobene nokuphepha kwedivayisi yonke, futhi izidingo zokuphepha nokuzinza ziphezulu kakhulu.
Kumaphampu amanzi okuhambisa amanzi e-OTC, into yokuqala okufanele icatshangelwe uhlobo oluthuthukisiwe, ukuvuthwa, ukuphepha kanye nokuthembeka kwephampu, kanye nokushintshana okujulile kobuchwepheshe, ukubonisana kanye nophenyo kuyadingeka. Iphampu yamanzi okuhambisa amanzi e-OTC iyimishini eyinhloko yesiteshi samandla esihlanganisiwe se-turbine yegesi esingu-800MW. Kuphela ngokukhetha abaphakeli abahle kakhulu kanye nobuchwepheshe bokuklama kanye nokukhiqiza obuthuthukisiwe lapho ukusebenza okuqhubekayo kwemishini yamandla kungaqinisekiswa khona, ukwandiswa kwezintshisekelo zenkampani kanye nomjikelezo wesikhathi eside wesiteshi samandla se-turbine yegesi esingu-800MW esisebenza khona.
Ukuphumelela kokufakwa kwephampu yamanzi okuhambisa amanzi ye-OTC yesiteshi sikagesi se-Rupsha esingu-800MW eBangladesh kubonisa ukuthi iphampu yamanzi okuhambisa amanzi ye-OTC yenkampani emkhakheni wokukhiqizwa kwamandla kagesi asebenzisa igesi iye yaqashelwa ngokugcwele amakhasimende ngokuthuthukisa amandla ayo aphelele, futhi yaqinisa ubuholi bezobuchwepheshe benkampani embonini. Yandisa ukuncintisana emakethe.
Ngaphezu kwalokho, iphampu ye-SLDT series BB4 multi-stage centrifugal eklanywe futhi yathuthukiswa yisitshalo saseDalian seLiancheng Group isetshenziswe ngokulandelana kuphrojekthi yokupheka yeShanxi Lubao Group Co., Ltd. ukusekela iphampu yamanzi okuphuza i-dry quenching waste heat boiler (izinga lokushisa lamanzi ebhoyila T=158℃), kanye nephampu yamanzi okuphuza i-waste heat boiler (izinga lokushisa lamanzi ebhoyila T=120-130℃) kanye neminye imisebenzi yobunjiniyela kuphrojekthi yokuphehla ugesi ye-Energy Technology Co., Ltd.
Ngamafuphi, ngokusekelwe emcabangweni wokuthuthukiswa okuluhlaza, ukuhleleka okucophelelayo, ukuphathwa okungathathi hlangothi, ukuqhubeka nokuhlinzeka amakhasimende ngezinsizakalo zekilasi eliphezulu, ukusebenza namakhasimende ukudala amandla ahlanzekile, angenakhabhoni eningi, aphephile futhi asebenzayo, ukuqhubeka nokuthatha indlela yokuthuthukiswa kwamandla asezingeni eliphezulu, nokuqhubeka nokudala amaphrojekthi ahlanzekile, angenakhabhoni eningi asezingeni eliphezulu. Umgomo nenhloso engaguquki yesitshalo saseDalian seLiancheng Group.
