Iyo Rupsha 800MW Yakasanganiswa Cycle Power Plant Project (Khulna) ndiyo hombe yega gasi turbine magetsi plant EPC chirongwa muBangladesh. Iri muKhulna Guta, Bangladesh, saiti iyi ingori makiromita 7.7 kubva kuguta reKhulna.
Muridzi wemari nemuridzi ndiBangladesh Northwest Power Generation Co., Ltd. (NWPGCL), uye EPC general kontrakta ndiyo mubatanidzwa weShanghai Electric Group Co., Ltd. (SEC) neItaly Ansaldo (AEN), uye Fujian Yongfu Electric. Power Design Co., Ltd. (YONGFU) Yeongororo yeprojekiti uye dhizaini unit.Iyo 800MW gasi turbine yakasanganiswa cycle power station project muBangladesh Rupusha inosanganisira maviri "F"-class (Alstom GT26) gasi turbines, maviri gasi turbine jenareta, maviri emarara ekupisa boilers, maviri akananga air-akatonhodzwa emhepo turbines uye maviri ehutsi turbine jenareta. Chigadzirwa chemagetsi chinoshandisa gasi remusikirwo semafuta makuru uye high-speed dizeli HSD semafuta ekuchengetedza. Simba remagetsi emagetsi rinotumirwa kunze kwemutsara ne 230kV zvishwe zvakapetwa kaviri uye zvakabatana kune yekumaodzanyemba substation yePGCB National Grid Khulna.
Iyo OTC yekudyisa pombi yemvura ye800MW gasi turbine yakasanganiswa cycle power station muBangladesh Rupusha inoshandiswa kuenderera mberi kwekupa mvura kune gasi turbine OTC uye kupa mvura inopisa kuOTC desuperheater uye pressure reducer (ona Mufananidzo 3). Kune zvikamu zviviri zvakazara, imwe neimwe unit ine 2 100% inokwana OTC feedwater pombi, imwe inomhanya uye imwe yakamira. Delivery medium name: OTC mvura yemvura; PH kukosha: 9.2~9.6; kuoma: 0mmol / l; conductivity: ≤ 0.3ms / cm; oxygen content: ≤ 7mg/l; iron ions: ≤ 20 mg / l; mhangura ions : ≤ 5mg/l; Iine silicon dioxide: ≤ 20mg/l.
Mukushanda kwakabatanidzwa kwechikwata, mvura yekudyisa kubva mumarara inopisa boiler (HRSG) high-pressure economizer inopinda mu-high-pressure OTC, uye kupisa kunobudiswa nemhepo inopisa yakadzoserwa inopinda mumhepo-yemvura inotenderera.
Iyo OTC yekudyisa mvura pombi inodiwa kuti isangane neakasiyana ekushanda mamiriro egasi turbine OTC. Kana pombi inomhanya ikafamba netsaona, pombi yekumira inogona kuiswa pakushanda yega. Kuti isangane nezvinodiwa zvakakosha zvekutanga-up, kuvhara uye bvunzo mamiriro, inogona kushandiswa nemaoko panzvimbo, uye yakashongedzerwa neDCS remote control interface mukamuri yekudzora unit.
Iyo 4 OTC feedwater pombi mu800MW gasi turbine yakasanganiswa kutenderera magetsi chiteshi muRupsha, Bangladesh yakatengwa neShanghai Electric Group Co., Ltd. (SEC) kuburikidza nekubhidha. Mushure mekutenderera kwakawanda kwekutaurirana kwehunyanzvi, vhidhiyo Q&A, uye nhaurirano dzebhizinesi, vakazove boka. Iyo SLDT yakawanda-nhanho centrifugal pombi yakagadzirwa uye yakagadziridzwa neDalian chirimwa yakazivisa kuhwina kwayo.
Iyo OTC yekudyisa pombi yemvura inoshandisa API610-BB4 maviri-magumo anotsigira imwe-shell radially split horizontal multi-stage centrifugal pombi yakagadzirwa uye yakagadziridzwa neDalian chirimwa cheLiancheng Group. Muenzaniso wayo ndeye SLDT80-260D×9 multi-stage centrifugal pombi.
OTC yekudyisa pombi yemvura, kushanda kwepombi yechiteshi ichi kune hukama nekuchengetedzeka kwechishandiso chose, uye zvinodiwa zvekuchengetedza nekugadzikana zvakakwirira kwazvo.
Pamapombi emvura yeOTC, chinhu chekutanga kutarisisa chimiro chepamberi, kukura, kuchengetedzeka uye kuvimbika kwepombi, uye zvakadzama tekinoroji kuchinjana, kubvunzana uye kuongorora kunodiwa. OTC yekudyisa mvura pombi ndiyo yakakosha midziyo ye800MW gasi turbine yakasanganiswa kutenderera magetsi chiteshi. Chete nekusarudza vatengesi vakanaka uye dhizaini yakagadziridzwa uye tekinoroji yekugadzira ndiyo inogona kuenderera kushanda kwemidziyo yemagetsi kuve nechokwadi, kukwidziridzwa kwezvido zvemakambani uye kutenderera kwenguva refu kwe800MW gasi turbine magetsi chiteshi.
Iko kubudirira kubhidha kwepombi yemvura yeOTC yeRupsha 800MW gasi turbine yakasanganiswa kutenderera chiteshi chemagetsi muBangladesh inoratidza kuti kambani yeOTC feedwater pombi mumunda wekugadzira magetsi anopfurwa negasi yakazivikanwa zvizere nevatengi nekuda kwesimba rayo rakakura, uye nekubatanidzwazve. hutungamiri hwekambani tekinoroji muindasitiri. Wedzera kukwikwidza kwemusika.
Pamusoro pezvo, iyo SLDT yakatevedzana BB4 yakawanda-nhanho centrifugal pombi yakagadzirwa uye yakagadziridzwa neDalian chirimwa cheLiancheng Boka yakatevedzana yakashandiswa muchirongwa chekubika cheShanxi Lubao Group Co., Ltd. (boiler mvura tembiricha T=158℃), uye Cathay Zhongke Yakachena Iyo tsvina inopisa bhaira yekudyisa pombi yemvura (boiler mvura tembiricha T=120-130 ℃) nemamwe mapurojekiti einjiniya muchirongwa chekugadzira magetsi cheEnergy Technology Co., Ltd.
Muchidimbu, zvichibva pane pfungwa yekukura kwegirinhi, kurongeka kwakasimba, manejimendi akaonda, ramba uchipa vatengi mabasa ekutanga, shanda nevatengi kugadzira yakachena, yakaderera-kabhoni, yakachengeteka uye inoshanda simba, ramba uchitora mugwagwa wepamusoro. -simba rekusimudzira simba, uye ramba uchigadzira yakakwirira-mhando yakachena, yakaderera-kabhoni yakasvibira mapurojekiti Icho chinangwa chisingachinji uye chinangwa cheDalian chirimwa cheLiancheng Group.
