Chirongwa cheRupsha 800MW Combined Cycle Power Plant (Khulna) ndicho chirongwa chikuru cheEPC chekugadzira turbine yegesi muBangladesh. Iri muKhulna City, Bangladesh, nzvimbo iyi iri makiromita 7.7 chete kubva muguta reKhulna.
Mudyari wemari uye muridzi wayo ndiBangladesh Northwest Power Generation Co., Ltd. (NWPGCL), uye kontrakita mukuru weEPC iboka reShanghai Electric Group Co., Ltd. (SEC) neAnsaldo (AEN) yeItaly, uye Fujian Yongfu Electric Power Design Co., Ltd. (YONGFU). Yechikamu chekuongorora mapurojekiti nekugadzira.Chirongwa chemagetsi che800MW gas turbine combined cycle station muBangladesh Rupusha chinosanganisira ma "turbines" maviri egasi e "F"-class (Alstom GT26), majenareta maviri egasi turbine, ma "waste heat boilers" maviri, ma "turbines" maviri esteam anotonhorerwa nemhepo zvakananga uye majenareta maviri esteam turbine. Chiteshi chemagetsi chinoshandisa gasi rechisikigo semafuta makuru uye high-speed diesel HSD semafuta ekuchengetedza. Simba rechiteshi chemagetsi rinotumirwa kunze kwetambo ne230kV double loops uye rakabatana nechikamu chekumaodzanyemba chePGCB National Grid Khulna.
Pombi yemvura yeOTC feed yechiteshi chemagetsi che800MW gas turbine combined cycle muBangladesh Rupusha inoshandiswa kupa mvura nguva dzose kuOTC gas turbine uye kupa mvura yekubvisa kupisa kuOTC desuperheater uye pressure reducer (ona Mufananidzo 3). Kune mayuniti maviri ese, yuniti imwe neimwe ine mapombi maviri eOTC feedwater ane simba re100%, rimwe richimhanya uye rimwe richimira. Zita repakati rekutumira: OTC water supply; PH value: 9.2~9.6; hardness: 0mmol/l; conductivity: ≤ 0.3ms/cm; oxygen content: ≤ 7mg/l; iron ions: ≤ 20 mg/l; copper ions: ≤ 5mg/l; Ine silicon dioxide: ≤ 20mg/l.
Mukushanda kwechikamu ichi pamwe chete, mvura inoyerera kubva muwaste heat boiler (HRSG) high-pressure economizer inopinda mu high-pressure OTC, uye kupisa kunoburitswa nemhepo inopisa inodzoserwa kunopinda mu steam-water circulation system.
Pombi yemvura yeOTC inodiwa kuti ishande mumamiriro akasiyana-siyana eOTC yeturbine yegesi. Kana pombi iri kushanda ikadonha netsaona, pombi iyi inogona kushanda yega. Kuti ishande zvinoenderana nezvinodiwa zvekutanga, kudzima uye kuyedza, inogona kushandiswa nemaoko panzvimbo yacho, uye ine DCS remote control interface mukamuri rekudzora unit.
Mapombi mana emvura eOTC ari muchiteshi chemagetsi che800MW gas turbine combined cycle muRupsha, Bangladesh akatengwa neShanghai Electric Group Co., Ltd. (SEC) kuburikidza nebhidha. Mushure mekutaurirana kwakawanda kwehunyanzvi, mibvunzo nemhinduro zvevhidhiyo, uye hurukuro dzebhizinesi, pakupedzisira vakava boka. Pombi yeSLDT ine nhanho dzakawanda yakagadzirwa uye yakagadzirwa nefekitori yeDalian yazivisa bhidha yayo yakahwina.
Pombi yemvura yeOTC inoshandisa pombi yeAPI610-BB4 ine mativi maviri inotsigira pombi imwe chete ine ganda rakapatsanurwa rakapatsanurwa rakatsetseka rakagadzirwa uye rakagadzirwa neDalian plant yeLiancheng Group. Modhi yayo iSLDT80-260D×9 pombi yepakati ine matanho akawanda.
Pombi yemvura yeOTC feed, mashandiro epombi iyi yechiteshi ane chekuita nekuchengetedzeka kwemudziyo wese, uye zvinodiwa zvekuchengetedza nekugadzikana zvakanyanya.
Kune mapombi emvura yeOTC, chinhu chekutanga chekufunga nezvacho imhando yepamusoro, kukura, kuchengetedzeka uye kuvimbika kwepombi, uye kuchinjana kwakadzama kwehunyanzvi, kubvunzana nekuferefeta zvinodiwa. Pombi yemvura yeOTC ndiyo michina inokosha yechiteshi chemagetsi che800MW gas turbine combined cycle power station. Kungosarudza vatengesi vakanaka chete uye tekinoroji yakagadzirwa zvakanaka uye yekugadzira ndiko kunogona kuve nechokwadi chekuti michina yemagetsi inoramba ichishandiswa, kuwedzera zvido zvemakambani uye kutenderera kwenguva refu kwechiteshi chemagetsi che800MW gas turbine power station.
Kubudirira kwekutenga pombi yemvura yeOTC yeRupsha 800MW gas turbine combined cycle power station muBangladesh kunoratidza kuti pombi yemvura yeOTC yekambani iyi mukugadzira magetsi anoshandiswa negasi yave kuzivikanwa zvizere nevatengi nekuda kwekuvandudza kwayo simba, uye kwakawedzera kusimbisa hutungamiriri hwetekinoroji yekambani muindasitiri iyi. Kuvandudza kukwikwidzana kwemusika.
Pamusoro pezvo, pombi yeSLDT series BB4 multi-stage centrifugal yakagadzirwa uye yakagadzirwa neDalian plant yeLiancheng Group yakashandiswa zvakatevedzana muchirongwa checoking cheShanxi Lubao Group Co., Ltd. kutsigira pombi yemvura yekudyara mvura yedry quenching waste heat boiler (tembiricha yemvura yeboiler T=158℃), uye Cathay Zhongke Clean The waste heat boiler feed water pombi (tembiricha yemvura yeboiler T=120-130℃) nemamwe mapurojekiti einjiniya muchirongwa chekugadzira magetsi cheEnergy Technology Co., Ltd.
Muchidimbu, zvichibva papfungwa yekuvandudza nharaunda, kurongeka kwakanyatsonaka, manejimendi asina kusimba, kuramba tichipa vatengi masevhisi epamusoro-soro, kushanda nevatengi kugadzira simba rakachena, risina kabhoni yakawanda, rakachengeteka uye rinoshanda zvakanaka, kuramba tichitora nzira yekuvandudza simba remhando yepamusoro, uye kuramba tichigadzira mapurojekiti emhando yepamusoro akachena, asina kabhoni yakawanda. Ndicho chinangwa chisingachinji uye chinangwa cheDalian plant yeLiancheng Group.
