Mashruuca Warshadda Korontada ee Wareegga Isku-dhafan ee Rupsha 800MW (Khulna) waa mashruuca EPC ee warshadda korontada ee gaaska ee ugu weyn Bangladesh. Waxay ku taal Magaalada Khulna, Bangladesh, goobtu waxay u jirtaa 7.7 kiiloomitir oo keliya magaalada Khulna.
Maalgashadayaasha iyo mulkiiluhu waa Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), qandaraaslaha guud ee EPC-na waa iskaashatada Shanghai Electric Group Co., Ltd. (SEC) iyo Ansaldo (AEN) ee Talyaaniga, iyo Fujian Yongfu Electric Power Design Co., Ltd. (YONGFU) ee sahanka mashruuca iyo cutubka naqshadeynta.Mashruuca saldhigga korontada ee isku-dhafka ah ee turbine-ka gaaska ee Bangladesh Rupusha waxaa ka mid ah laba turbine oo gaas ah oo "F" ah (Alstom GT26), laba matoor oo gaas ah, laba kuleyliye kuleyl qashin ah, laba matoor oo uumi ah oo si toos ah hawada loogu qaboojiyo iyo laba matoor oo uumi ah. Warshadda korontada waxay u isticmaashaa gaaska dabiiciga ah shidaalka ugu weyn iyo HSD-ka naaftada xawaaraha sare leh shidaalka kaydka ah. Awoodda warshadda korontada waxaa laga soo diraa khadka iyadoo la adeegsanayo wareegyo laba jibbaaran oo 230kV ah waxaana lagu xiraa saldhigga koonfureed ee PGCB National Grid Khulna.
Bamka biyaha quudinta OTC ee saldhigga korontada isku dhafan ee wareegga gaaska ee 800MW ee Bangladesh Rupusha waxaa loo isticmaalaa biyo joogto ah oo loogu talagalay turbine-ka gaaska OTC iyo in biyo kululaynta lagu siiyo qalabka kululeeyaha OTC iyo qalabka yareeya cadaadiska (fiiri Jaantuska 3). Guud ahaan waxaa jira laba cutub, cutub kastaa wuxuu leeyahay 2 bambo oo biyaha quudinta OTC ah oo awood u leh 100%, mid socda kan kalena heeganka ah. Magaca dhexe ee keenista: Biyaha OTC; Qiimaha PH: 9.2~9.6; adkaanta: 0mmol/l; wadista: ≤ 0.3ms/cm; ka kooban oksijiin: ≤ 7mg/l; ayoonada birta: ≤ 20 mg/l; ayoonada naxaasta: ≤ 5mg/l; Waxaa ku jira silicon dioxide: ≤ 20mg/l.
Hawlgalka wareegga isku dhafan ee cutubka, biyaha quudinta ee ka imanaya dhaqaale-yaqaanka kulaylka qashinka (HRSG) ee cadaadiska sare leh ayaa galaya OTC-ga cadaadiska sare leh, kulaylka ay sii dayso hawada kulul ee la soo celiyayna wuxuu galayaa nidaamka wareegga biyaha uumiga.
Bamka biyaha quudinta ee OTC waxaa looga baahan yahay inuu buuxiyo shuruudaha kala duwan ee hawlgalka ee gaaska turbine OTC. Marka bamka shaqeynaya si kama' ah u dhaco, bamka heeganka ah ayaa si toos ah loo hawlgelin karaa. Si loo buuxiyo shuruudaha gaarka ah ee xaaladaha bilowga, xidhitaanka iyo tijaabada, waxaa gacanta lagu shaqeyn karaa goobta, waxaana lagu qalabeeyay is-dhexgalka kontoroolka fog ee DCS ee qolka kontoroolka cutubka.
4-ta bambo ee biyaha quudinta ee OTC ee ku jira saldhigga korontada ee isku-dhafka ah ee gaaska ee 800MW ee Rupsha, Bangladesh waxaa iibsaday Shanghai Electric Group Co., Ltd. (SEC) iyada oo loo marayo dalab. Ka dib wareegyo badan oo isgaarsiineed oo farsamo, su'aalo iyo jawaabo muuqaal ah, iyo wadahadallo ganacsi, ugu dambeyntii waxay noqdeen koox. Bamka SLDT ee mashiinnada badan ee mashiinnada dhexe ee ay naqshadeysay oo ay samaysay warshadda Dalian ayaa ku dhawaaqday dalabkeedii guusha.
Bamka biyaha quudinta OTC wuxuu adeegsadaa bamka laba-geesoodka ah ee API610-BB4 oo taageero hal-qolof ah oo dhinac-dhinac ah oo dhinac-dhinac ah oo ay naqshadeysay oo ay samaysay warshadda Dalian ee Liancheng Group. Moodelkeedu waa bamka dhul-goosadka ee SLDT80-260D × 9 oo marxalado badan leh.
Bamka biyaha quudinta OTC, hawlgalka bamka saldhiggan wuxuu la xiriiraa badbaadada qalabka oo dhan, shuruudaha badbaadada iyo xasilloonidana aad bay u sarreeyaan.
Bambooyinka biyaha quudinta ee OTC, waxa ugu horreeya ee la tixgelinayo waa dabeecadda horumarsan, bisaylka, badbaadada iyo isku halaynta bamka, iyo is-weydaarsi farsamo oo qoto dheer, la-tashiyo iyo baaritaanno ayaa loo baahan yahay. Bamka biyaha quudinta ee OTC waa qalabka ugu muhiimsan ee saldhigga korontada ee isku-darka ah ee 800MW ee gaaska. Kaliya iyadoo la dooranayo alaab-qeybiyeyaal heer sare ah iyo tignoolajiyada naqshadeynta iyo wax-soo-saarka ee la hagaajiyay ayaa la hubin karaa hawlgalka joogtada ah ee qalabka korontada, kordhinta danaha shirkadaha iyo wareegga muddada-dheer ee saldhigga korontada ee gaaska ee 800MW.
Tartankii guusha lahaa ee bamka biyaha quudinta OTC ee saldhigga korontada isku-dhafka ah ee Rupsha 800MW ee Bangladesh wuxuu muujinayaa in bamka biyaha quudinta OTC ee shirkadda ee ku takhasusay soo saarista korontada gaaska lagu shido ay si buuxda u aqoonsadeen macaamiishu horumarinta buuxda ee xoogga, waxayna sii xoojisay hoggaanka tignoolajiyada ee shirkadda ee warshadaha. Kor u qaad tartanka suuqa.
Intaa waxaa dheer, bamka SLDT taxanaha BB4 ee mashiinnada badan ee mashiinnada dhexe ee ay naqshadeysay oo ay horumarisay warshadda Dalian ee Liancheng Group ayaa si isdaba joog ah loogu isticmaalay mashruuca kookaynta ee Shanxi Lubao Group Co., Ltd. si loo taageero bamka biyaha ee kuleyliyaha qashinka ee qalajinaya (heerkulka biyaha kulayliyaha T=158℃), iyo Cathay Zhongke Clean Bamka biyaha ee kuleyliyaha qashinka (heerkulka biyaha kulayliyaha T=120-130℃) iyo mashaariicda kale ee injineernimada ee mashruuca korontada ee Energy Technology Co., Ltd.
Marka la soo koobo, iyadoo lagu saleynayo fikradda horumarinta cagaaran, abaabul taxaddar leh, maaraynta caatada ah, sii wad inaad siiso macaamiisha adeegyo heer sare ah, la shaqeyso macaamiisha si loo abuuro tamar nadiif ah, kaarboon yar, ammaan ah oo hufan, sii wad inaad qaaddo waddada horumarinta tamarta tayada sare leh, iyo inaad sii waddo abuurista mashaariic cagaaran oo nadiif ah oo kaarboon yar oo tayo sare leh. Waa yoolka iyo ujeeddada aan isbeddelin ee warshadda Dalian ee Kooxda Liancheng.
