Iprojekthi yeRupsha 800MW Combined Cycle Power Plant (Khulna) yeyona projekthi inkulu ye-EPC yesikhululo samandla se-turbine yegesi eBangladesh. IkwiSixeko saseKhulna, eBangladesh, le ndawo ikumgama weekhilomitha eziyi-7.7 kuphela ukusuka kwisixeko saseKhulna.
Umtyali-mali kunye nomnini yiBangladesh Northwest Power Generation Co., Ltd. (NWPGCL), kwaye ikontrakta jikelele ye-EPC yinkampani yeShanghai Electric Group Co., Ltd. (SEC) kunye ne-Ansaldo yase-Italy (AEN), kunye neFujian Yongfu Electric Power Design Co., Ltd. (YONGFU) Kwicandelo lophando lweprojekthi kunye noyilo.Iprojekthi yesikhululo samandla esijikelezileyo se-800MW gas turbine eBangladesh iRupusha iquka iiturbine ezimbini zegesi ze-“F” (Alstom GT26), iijenereyitha ezimbini ze-turbine yegesi, iibhoyila ezimbini zobushushu obumdaka, iiturbine ezimbini zomphunga ezipholisiweyo ngomoya ngqo kunye neejenereyitha ezimbini ze-turbine yomphunga. Isikhululo samandla sisebenzisa igesi yendalo njengepetroli ephambili kunye ne-HSD yedizili ekhawulezayo njengepetroli yokuxhasa. Amandla esikhululo samandla athunyelwa ngaphandle komgca ngee-230kV double loops kwaye aqhagamshelwe kwisitishi esisezantsi sePGCB National Grid Khulna.
Ipompo yamanzi e-OTC yesikhululo samandla se-turbine yegesi esidibeneyo se-800MW eBangladesh iRupusha isetyenziselwa ukubonelela ngamanzi rhoqo kwi-turbine yegesi i-OTC kunye nokubonelela ngamanzi asusa ubushushu kwi-OTC desuperheater kunye ne-pressure reducer (jonga uMfanekiso 3). Kukho iiyunithi ezimbini zizonke, iyunithi nganye ixhotyiswe ngeempompo zamanzi e-OTC ezingama-2 100%, enye isebenza kwaye enye ikwimeko yokulinda. Igama eliphakathi lokuhanjiswa: Unikezelo lwamanzi lwe-OTC; Ixabiso le-PH: 9.2~9.6; ubunzima: 0mmol/l; ukuqhuba: ≤ 0.3ms/cm; umxholo weoksijini: ≤ 7mg/l; ii-ion zentsimbi: ≤ 20 mg/l; ii-ion zekopolo: ≤ 5mg/l; Iqulethe i-silicon dioxide: ≤ 20mg/l.
Kwinkqubo yokusebenza ngomjikelo odibeneyo weyunithi, amanzi avela kwi-waste heat boiler (HRSG) high-pressure economizer angena kwi-high-pressure OTC, kwaye ubushushu obukhutshwa ngumoya oshushu obufunyenweyo bungena kwinkqubo yokujikeleza kwamanzi ngomphunga.
Impompo yamanzi e-OTC iyadingeka ukuze ihlangabezane neemeko ezahlukeneyo zokusebenza kwe-OTC ye-turbine yegesi. Xa impompo esebenzayo ikhubeka ngengozi, impompo yokulinda inokusetyenziswa ngokuzenzekelayo. Ukuze ihlangabezane neemfuno ezikhethekileyo zokuqalisa, ukuvala kunye neemeko zovavanyo, ingasetyenziswa ngesandla kwindawo, kwaye ixhotyiswe nge-interface yolawulo olukude lwe-DCS kwigumbi lolawulo lweyunithi.
Iimpompo zamanzi ezi-4 ze-OTC kwisikhululo samandla esijikelezileyo se-turbine yegesi ye-800MW eRupsha, eBangladesh zathengwa yiShanghai Electric Group Co., Ltd. (SEC) ngokubhida. Emva kwemijikelo emininzi yonxibelelwano lobuchwephesha, imibuzo neempendulo zevidiyo, kunye neengxoxo zoshishino, ekugqibeleni zaba liqela. Ipompo ye-centrifugal ye-SLDT enezigaba ezininzi eyilwe kwaye yaphuhliswa sisityalo saseDalian ibhengeze isicelo sayo esiphumeleleyo.
Ipompo yamanzi ye-OTC isebenzisa ipompo ye-API610-BB4 exhasa i-single-shell ethe tyaba ehlulwe ngokwe-radially multi-stage centrifugal eyilwe kwaye yaphuhliswa sisityalo saseDalian seLiancheng Group. Imodeli yayo yipompo ye-SLDT80-260D×9 multi-stage centrifugal.
Ipompo yamanzi ye-OTC feed, ukusebenza kwale pump yesitishi kunxulumene nokhuseleko lwesixhobo sonke, kwaye iimfuno zokhuseleko nokuzinza ziphezulu kakhulu.
Kwiimpompo zamanzi okuhambisa amanzi ze-OTC, into yokuqala ekufuneka iqwalaselwe bubunjani obuphambili, ukuvuthwa, ukhuseleko kunye nokuthembeka kwempompo, kwaye kufuneka utshintshiselwano olunzulu lobuchwephesha, iingcebiso kunye nophando. Impompo yamanzi okuhambisa amanzi ze-OTC zizixhobo eziphambili zesikhululo samandla esijikelezileyo se-800MW se-turbine yegesi. Kuphela ngokukhetha ababoneleli ababalaseleyo kunye noyilo olucwangcisiweyo kunye netekhnoloji yokuvelisa apho ukusebenza okuqhubekayo kwezixhobo zamandla kunokuqinisekiswa, ukwandiswa kweminqweno yenkampani kunye nomjikelo wexesha elide wesikhululo samandla se-turbine yegesi ye-800MW esiqhutywayo.
Ukuphumelela kwebhidi yepompo yamanzi e-OTC yesikhululo samandla se-turbine yegesi i-Rupsha 800MW eBangladesh kubonisa ukuba ipompo yamanzi e-OTC yenkampani kwicandelo lokuvelisa umbane osebenzisa igesi iye yaqatshelwa ngokupheleleyo ngabathengi ngokuphucula amandla ayo apheleleyo, kwaye yaqinisa ubunkokeli betekhnoloji yenkampani kushishino. Ukuphucula ukhuphiswano lwemarike.
Ukongeza, ipompo ye-SLDT series BB4 multi-stage centrifugal eyilwe kwaye yaphuhliswa sisityalo saseDalian seLiancheng Group isetyenzisiwe ngokulandelelana kwiprojekthi yokucola yeShanxi Lubao Group Co., Ltd. ukuxhasa ipompo yamanzi e-dry quenching waste heat boiler feed (ubushushu bamanzi e-boiler T=158℃), kunye neCathay Zhongke Clean The waste heat boiler feed water pump (ubushushu bamanzi e-boiler T=120-130℃) kunye nezinye iiprojekthi zobunjineli kwiprojekthi yokuvelisa umbane ye-Energy Technology Co., Ltd.
Ngamafutshane, ngokusekelwe kwingcamango yophuhliso oluluhlaza, ulungelelwaniso olucokisekileyo, ulawulo olungenamthungo, ukuqhubeka nokubonelela abathengi ngeenkonzo zodidi oluphezulu, ukusebenza nabathengi ukudala amandla acocekileyo, angenakhabhoni eninzi, akhuselekileyo nasebenzayo, ukuqhubeka nokuthatha indlela yophuhliso lwamandla olukumgangatho ophezulu, kunye nokuqhubeka nokudala iiprojekthi ezicocekileyo, ezingenakhabhoni eninzi. Yinjongo engaguqukiyo kunye nenjongo yesityalo saseDalian seLiancheng Group.
