Rupsha 800MW Combined Cycle Power Plant Project (Khulna) waa mashruuca tamarta marawaxadaha gaaska kaliya ee EPC ee Bangladesh.Waxay ku taal magaalada Khulna, Bangladesh, goobta ayaa 7.7 kilomitir u jirta magaalada Khulna.
Maalgeliyaha iyo mulkiilaha waa Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), qandaraaslaha guud ee EPC waa daladda Shanghai Electric Group Co., Ltd. (SEC) iyo Talyaaniga Ansaldo (AEN), iyo Fujian Yongfu Electric Naqshadeynta Awoodda Co., Ltd. (YONGFU) ee sahaminta mashruuca iyo qaybta naqshadeynta.Marawaxada gaaska ee 800MW ee isku dhafka ah ee mashruuca saldhiga wareegga korantada ee Bangladesh Rupusha waxa ka mid ah laba marawaxadaha gaaska "F"-heer (Alstom GT26), laba koronto dhaliye gaas, laba kuleyliyaha qashinka ah, laba marawaxadaha uumiga si toos ah u qaboojiyey iyo laba mishiinnada marawaxadaha.Warshada korontadu waxay isticmaashaa gaaska dabiiciga ah shidaalka ugu muhiimsan iyo naaftada xawaaraha sare leh ee HSD sida shidaalka kaydka ah.Awoodda warshadda korantada waxaa laga diraa xariiqda 230kV oo siddo laba jibbaaran waxayna ku xiran tahay saldhigga koonfureed ee PGCB National Grid Khulna.
Matoorka biyaha ee OTC ee 800MW marawaxadaha gaaska isku dhafka ah ee saldhigga korantada wareegga wareegga ee Bangladesh Rupusha waxaa loo isticmaalaa bixinta biyaha joogtada ah ee marawaxadaha gaaska OTC iyo in la siiyo biyaha kululeeyaha kululeeyaha OTC iyo cadaadiska yareeya (eeg sawirka 3).Guud ahaan waxaa jira laba unug, unug kastaa waxa uu ku qalabaysan yahay 2 100% matoorada biyaha quudinta ee OTC, mid socda iyo kan kale oo heegan ah.Bixinta Magaca dhexdhexaadka ah: OTC biyaha;Qiimaha PH: 9.2 ~ 9.6;adkaanta: 0mmol/l;dhaqdhaqaaqa: ≤ 0.3ms / cm;oksijiinta ku jirta: ≤ 7mg/l;ions birta: ≤ 20 mg/l;ions naxaas ah: ≤ 5mg/l;Ka kooban Silicon dioxide: ≤ 20mg/l.
Hawlgalka wareegga isku dhafan ee cutubka, biyaha quudinta ee kuleyliyaha kulaylka qashinka (HRSG) ee dhaqaalaha cadaadiska sarreeya ayaa galaya cadaadiska sare ee OTC, iyo kulaylka ay sii daayaan hawada kulul ee la soo kabsaday waxay gashaa nidaamka wareegga biyaha uumiga.
Bamka biyaha quudinta OTC ayaa looga baahan yahay inuu buuxiyo shuruudaha kala duwan ee hawlgalka marawaxadaha gaaska OTC.Marka bamka ordaya uu si lama filaan ah u socdo, bamka heeganka ah si toos ah ayaa loo hawlgelin karaa.Si loo buuxiyo shuruudaha gaarka ah ee bilawga, xidhitaanka iyo xaaladaha tijaabada, waxaa si gacan ah loogu shaqayn karaa goobta, waxaana lagu qalabeeyaa is-dhexgalka fog ee DCS ee qolka kantaroolka cutubka.
4-ta matoorada biyaha quudinta ee OTC ee ku jira marawaxadaha gaaska ee 800MW isku darka korantada wareegga wareegga ee Rupsha, Bangladesh waxaa soo iibsatay Shanghai Electric Group Co., Ltd. (SEC) iyadoo loo marayo tartan.Kadib wareegyo badan oo xiriir farsamo ah, Q&A fiidiyoow ah, iyo gorgortan ganacsi, ugu dambeyntii waxay noqdeen koox.SLDT bamka centrifugal ee heerar badan leh oo ay nashqadaysay oo ay samaysay warshadda Dalian ayaa ku dhawaaqday dalabkeeda guusha.
Bamka biyaha quudinta OTC waxay isticmaashaa API610-BB4 laba-dhammaad oo taageeraya hal qolof shucaac ah oo kala qaybsan oo toosan bamka centrifugal ee heerar badan leh oo loogu talagalay oo ay horumarisay warshadda Dalian ee Kooxda Liancheng.Qaabkeedu waa SLDT80-260D × 9 bamka centrifugal ee marxaladaha badan.
OTC quudinta bamka biyaha, hawlgalka bamka saldhiggan wuxuu la xiriiraa badbaadada qalabka oo dhan, iyo shuruudaha badbaadada iyo xasilloonida ayaa aad u sarreeya.
Matoorada biyaha quudinta ee OTC, waxa ugu horreeya ee la tixgelinayo waa dabeecadda horumarsan, qaan-gaarnimada, badbaadada iyo isku halaynta bamka, iyo isweydaarsi farsamo oo qotodheer, la-tashi iyo baaritaan ayaa loo baahan yahay.Matoorka biyaha quudinta OTC waa qalabka muhiimka ah ee marawaxadaha gaaska ee 800MW isku darka saldhigga korantada wareegga.Kaliya adoo dooranaya alaab-qeybiyeyaal aad u fiican iyo naqshadaynta la hagaajiyay iyo tignoolajiyada wax soo saarka ayaa la xaqiijin karaa hawlgalka joogtada ah ee qalabka korantada, kordhinta danaha shirkadaha iyo wareegga muddada fog ee 800MW gaaska tamarta marawaxadaha.
Qandaraaska lagu guulaystay ee bamka biyaha quudinta ee OTC ee Rupsha 800MW marawaxadaha gaaska isku jira saldhiga korantada wareegga wareegga ee Bangladesh waxay tilmaamaysaa in bamka biyaha quudinta ee shirkadda ee beerta tamarta gaaska ay si buuxda macaamiisha u aqoonsadeen horumarkeeda xoogeed ee dhamaystiran, oo la sii xoojiyay. hogaanka teknoolajiyada ee shirkadda ee warshadaha.Kobcinta tartanka suuqa.
Intaa waxaa dheer, SLDT taxanaha BB4 bamka centrifugal multi-stage oo loogu talagalay oo ay horumarisay warshad Dalian ee Liancheng Group ayaa si isdaba joog ah loogu adeegsaday mashruuca coking ee Shanxi Lubao Group Co., Ltd. (heerkulka biyaha kululeeyaha T = 158 ℃), iyo Cathay Zhongke Nadiifi Kuleyliyaha qashinka qashinka wuxuu quudiyaa bamka biyaha (heerkulka biyaha kululeeyaha T = 120-130 ℃) iyo mashaariicda kale ee injineernimada ee mashruuca koronto ee tamarta Technology Co., Ltd.
Marka la soo koobo, iyada oo ku saleysan fikradda horumarinta cagaaran, urur si taxadar leh, maarayn caatada ah, sii wadida bixinta macaamiisha adeegyada heerka koowaad, la shaqeeyaan macaamiisha si ay u abuuraan nadiif, kaarboon-yar, ammaan iyo tamar hufan, sii wad qaadashada wadada sare. Horumarinta tamarta tayada leh, iyo sii wadida abuurista tayada sare ee nadiifka ah, mashaariicda cagaaran ee kaarboon-yar Waa yoolka iyo ujeedada aan isbeddelin ee warshadda Dalian ee Kooxda Liancheng.
