IProjekthi ye-Rupsha 800MW Combined Cycle Power Plant (Khulna) yeyona projekthi inkulu ye-EPC yeziko lombane le-injini yegesi enye e-Bangladesh.Ifumaneka kwisiXeko saseKhulna, eBangladesh, indawo ekumgama oziikhilomitha ezisi-7.7 kuphela ukusuka kwisixeko saseKhulna.
Umtyali-mali kunye nomnini yi-Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), kunye nekontraka ye-EPC jikelele yi-consortium ye-Shanghai Electric Group Co., Ltd. (SEC) kunye ne-Italian Ansaldo (AEN), kunye ne-Fujian Yongfu Electric. Power Design Co., Ltd. (YONGFU) Kuvavanyo lweprojekthi kunye neyunithi yoyilo.I-800MW iprojekthi yesikhululo samandla somjikelo odityanisiweyo wesikhululo samandla e-Bangladesh i-Rupusha ibandakanya iiinjini zegesi ze-"F"-class (Alstom GT26) ezimbini, iijenereyitha ze-injini yegesi ezimbini, izibiyitha zobushushu ezibini, ii-injini zomphunga ezimbini ezithe ngqo kunye neejenereyitha ezimbini ze-injini yomphunga.Iziko lombane lisebenzisa irhasi yendalo njengamafutha aphambili kunye ne-HSD yedizili enesantya esiphezulu njengamafutha axhasayo.Amandla omzi-mveliso athunyelwa ngaphandle komgca we-230kV iilophu eziphindwe kabini kwaye ziqhagamshelwe kwisitishi esisezantsi sePGCB National Grid Khulna.
Impompo yamanzi ye-OTC ye-800MW yegesi edityanisiweyo yomjikelezo wesikhululo samandla e-Bangladesh Rupusha isetyenziselwa unikezelo lwamanzi oluqhubekayo kwi-OTC ye-injini yerhasi kunye nokubonelela ngamanzi atshisayo kwi-OTC desuperheater kunye nesinciphisi soxinzelelo (jonga uMfanekiso 3).Kukho iiyunithi ezimbini zizonke, iyunithi nganye ixhotyiswe 2 100% umthamo iimpompo feed water OTC, enye esebenzayo kunye nezinye standby.Ukuhanjiswa kwegama eliphakathi: Unikezelo lwamanzi lwe-OTC;PH ixabiso: 9.2~9.6;ubunzima: 0mmol / l;conductivity: ≤ 0.3ms / cm;umxholo we-oxygen: ≤ 7mg / l;i-iron ions: ≤ 20 mg / l;iiyoni zobhedu: ≤ 5mg/l;Iqulethe i-silicon dioxide: ≤ 20mg/l.
Kumsebenzi womjikelo odityanisiweyo weyunithi, i-feedwater esuka kwibhoyila yobushushu benkunkuma (HRSG) i-high-pressure economizer ingena kwi-OTC yoxinzelelo oluphezulu, kwaye ubushushu obukhutshwe ngumoya oshushu obufunyenweyo bungena kwinkqubo yokujikeleza kwamanzi ngomphunga.
Impompo yamanzi esondlo se-OTC iyafuneka ukuhlangabezana neemeko ezahlukeneyo zokusebenza ze-OTC ye-gas turbine.Xa impompo ebalekayo ihambe ngempazamo, impompo elindileyo inokufakwa ekusebenzeni ngokuzenzekelayo.Ukuze kuhlangatyezwane neemfuno ezikhethekileyo zokuqalisa, ukuvala kunye neemeko zovavanyo, inokuqhutywa ngesandla kwisiza, kwaye ixhotyiswe nge-DCS yokulawula ujongano olukude kwigumbi lokulawula iyunithi.
Iimpompo ze-4 ze-OTC zamanzi kwi-800MW ye-gas turbine edibeneyo yomjikelezo wesikhululo samandla e-Rupsha, e-Bangladesh zathengwa yi-Shanghai Electric Group Co., Ltd. (SEC) ngokubhida.Emva kwemijikelo emininzi yonxibelelwano lobugcisa, iQ&A yevidiyo, kunye nothethathethwano lweshishini, ekugqibeleni baba liqela.Ipompo ye-SLDT ye-multi-stage centrifugal eyenzelwe kwaye yaphuhliswa sisityalo saseDalian ibhengeze ukuphumelela kwayo.
Ipompo yamanzi ye-OTC feed isebenzisa i-API610-BB4 isiphelo sesibini esixhasa i-shell-shell radially split horizontal multi-stage centrifugal pump eyilwe kwaye iphuhliswe sisityalo saseDalian seLiancheng Group.Imodeli yayo yi-SLDT80-260D×9 impompo ye-centrifugal enezigaba ezininzi.
Ipompo yamanzi ye-OTC feed, ukusebenza kwale mpompo yesitishi inxulumene nokhuseleko lwesixhobo sonke, kwaye iimfuno zokhuseleko kunye nokuzinza ziphezulu kakhulu.
Kwiimpompo zamanzi ze-OTC, into yokuqala ekufuneka iqwalaselwe yindalo ephambili, ukukhula, ukhuseleko kunye nokuthembeka kwempompo, kunye notshintshiselwano olunzulu lobugcisa, ukubonisana kunye nophando olufunekayo.Impompo yamanzi esondlo se-OTC sisixhobo esingundoqo se-800MW ye-iturbine yerhasi edityanisiweyo kwisikhululo samandla somjikelo wamandla.Kuphela ngokukhetha ababoneleli abagqwesileyo kunye noyilo olulungisiweyo kunye nobugcisa bokuvelisa apho ukusebenza okuqhubekayo kwezixhobo zombane kungaqinisekiswa, ukwandiswa kwemidla yamaqumrhu kunye nomjikelo wexesha elide wesikhululo samandla omoya we-800MW oqhutywayo.
Ibhidi eyimpumelelo yempompo yamanzi ye-OTC ye-Rupsha 800MW ye-iturbine yegesi edityanisiweyo kwisikhululo samandla somjikelo e-Bangladesh ibonisa ukuba i-OTC yenkampani yempompo yamanzi kwindawo yokuvelisa amandla ngegesi iye yamkelwa ngokupheleleyo ngabathengi ngokuphuculwa kwayo okubanzi kwamandla, kwaye idityaniswe ngakumbi. ubunkokeli betekhnoloji yenkampani kushishino.Ukuphucula ukhuphiswano lwemarike.
Ukongeza, uthotho lwe-SLDT lwe-BB4 yenqanaba lempompo ye-centrifugal enemigangatho emininzi eyenzelwe kwaye yaphuhliswa yisityalo saseDalian seLiancheng Group isetyenziswe ngokulandelelana kwiprojekthi yokupheka ye-Shanxi Lubao Group Co., Ltd. (iqondo lobushushu lamanzi ebhoyila T=158℃), kunye neCathay Zhongke Coca Ipompu yamanzi ebhoyila yobushushu benkunkuma (ubushushu bamanzi ebhoyila T=120-130℃) kunye nezinye iiprojekthi zobunjineli kwiprojekthi yokuvelisa amandla e-Energy Technology Co., Ltd.
Ngamafutshane, ngokusekelwe kwingcamango yophuhliso oluluhlaza, umbutho ocokisekileyo, ulawulo oluncinci, luqhubeka nokubonelela abathengi ngeenkonzo zeklasi yokuqala, basebenze kunye nabathengi ukudala i-carbon ecocekileyo, ephantsi, ekhuselekileyo kunye namandla asebenzayo, baqhubeke bethatha indlela ephezulu. -umgangatho wophuhliso lwamandla, kwaye uqhubeke nokudala umgangatho ophezulu ococekileyo, iiprojekthi eziluhlaza eziphantsi kwekhabhoni Yinjongo engatshintshiyo kunye nenjongo yesityalo saseDalian seLiancheng Group.
