Umushinga w’uruganda rukora amashanyarazi rwa Rupsha rwa 800MW (Khulna) ni wo mushinga munini wa EPC w’uruganda rukora amashanyarazi rwa gaze muri Bangladesh. Uherereye mu Mujyi wa Khulna, muri Bangladesh, aho hantu hari ku birometero 7.7 gusa uvuye mu mujyi wa Khulna.
Umushoramari akaba na nyirayo ni Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), naho rwiyemezamirimo mukuru wa EPC ni ihuriro rya Shanghai Electric Group Co., Ltd. (SEC) na Ansaldo yo mu Butaliyani (AEN), na Fujian Yongfu Electric Power Design Co., Ltd. (YONGFU) Ku bijyanye n'ishami rishinzwe ubushakashatsi n'igishushanyo mbonera cy'imishinga.Umushinga w’ingufu za turbine ya gaze ya 800MW muri Bangladesh Rupusha urimo turbine ebyiri za gaze zo mu bwoko bwa "F" (Alstom GT26), moteri ebyiri za gaze, boiler ebyiri zishyushya imyanda, turbine ebyiri zikonjesha umwuka mu buryo butaziguye hamwe na moteri ebyiri za turbine zishyushya umwuka. Uruganda rukoresha gaze karemano nk'amavuta nyamukuru na HSD ya mazutu yihuta nk'amavuta yo kwifashisha. Ingufu z'uruganda zisohoka mu murongo zikoresheje imiyoboro ibiri ya 230kV kandi zihujwe na substation yo mu majyepfo ya PGCB National Grid Khulna.
Pompe y'amazi ya OTC yo muri sitasiyo y'amashanyarazi ya turbine ya gaze ya 800MW muri Bangladesh Rupusha ikoreshwa mu gutanga amazi ahoraho kuri turbine ya gaze OTC no gutanga amazi ashyushye kuri OTC desuperheater na pressure reduction (reba Ishusho ya 3). Hari ibice bibiri muri rusange, buri gice gifite pompe 2 za OTC feeder za OTC zifite ubushobozi bwa 100%, imwe ikora indi ihagaze. Izina ry'itangwa: OTC water supply; Agaciro ka PH: 9.2 ~ 9.6; ubukana: 0mmol / l; conductivity: ≤ 0.3ms / cm; ogisijeni: ≤ 7mg / l; ioni z'icyuma: ≤ 20 mg / l; ioni z'umuringa: ≤ 5mg / l; Irimo silicon dioxide: ≤ 20mg / l.
Mu mikorere y’iyi mashini, amazi aturuka muri boiler y’ubushyuhe bw’imyanda (HRSG) yinjizwa muri OTC ifite umuvuduko mwinshi, naho ubushyuhe buva mu mwuka ushyushye bugasubizwamo bukinjira muri sisitemu yo kuzenguruka amazi n’umwuka.
Pompe y'amazi ya OTC irakenewe kugira ngo yuzuze imiterere itandukanye y'imikorere ya turbine ya gaze OTC. Iyo pompe ikora yaguye ku bw'impanuka, pompe ihoraho ishobora gushyirwa mu bikorwa mu buryo bwikora. Kugira ngo yuzuze ibisabwa byihariye byo gutangiza, kuzimya no gupima, ishobora gukoreshwa n'intoki aho ikorera, kandi ifite uburyo bwo kugenzura bwa DCS mu cyumba cyo kugenzura.
Pompe enye za OTC zikoreshwa mu gukwirakwiza amazi muri sitasiyo y'amashanyarazi ya turbine ya gaze ya 800MW i Rupsha, muri Bangladesh zaguzwe na Shanghai Electric Group Co., Ltd. (SEC) binyuze mu gupiganwa. Nyuma y'inshuro nyinshi z'itumanaho rya tekiniki, ibibazo n'ibisubizo kuri videwo, ndetse n'ibiganiro by'ubucuruzi, amaherezo zabaye itsinda. Pompe ya SLDT ikoresha imashini zikoresha amashanyarazi mu byiciro byinshi yakozwe kandi ikanakorwa n'uruganda rwa Dalian yatangaje ko yatsinze.
Pompe y'amazi ya OTC ikoresha pompe ya API610-BB4 ifite impande ebyiri ishyigikira imashini imwe ifite ibice byinshi kandi ikora neza, yakozwe kandi igakorwa n'uruganda rwa Dalian rwa Liancheng Group. Icyitegererezo cyayo ni pompe ya SLDT80-260D×9 ifite ibice byinshi.
Pompe y'amazi ya OTC, imikorere y'iyi pompe ijyanye n'umutekano w'igikoresho cyose, kandi ibisabwa kugira ngo umutekano n'ubudahangarwa birusheho kuba byinshi.
Ku mapompo ya OTC, ikintu cya mbere kigomba kwitabwaho ni imiterere igezweho, igihe igeze, umutekano n'ubwizerwe bw'ipompo, kandi hakenewe uburyo bwimbitse bwo guhanahana amakuru, inama n'iperereza. Pompo y'amazi ya OTC ni ibikoresho by'ingenzi bya sitasiyo y'amashanyarazi ya turbine ya 800MW. Guhitamo abatanga serivisi nziza n'ikoranabuhanga rigezweho mu gukora ni byo byonyine bishobora gutuma ibikoresho by'amashanyarazi bikomeza gukoreshwa, inyungu z'ibigo birushaho kwiyongera ndetse n'imikorere y'igihe kirekire ya sitasiyo y'amashanyarazi ya turbine ya 800MW ikora.
Ipiganwa ryakozwe neza rya pompe ya OTC yo gukoresha amashanyarazi ya turbine ya gaze ya Rupsha 800MW muri Bangladesh, bigaragaza ko pompe ya OTC y’isosiyete mu bijyanye no gutanga amashanyarazi akoresha gaze yashimwe n’abakiriya bayo kubera kunoza ingufu zayo, kandi binashimangira imiyoborere y’ikoranabuhanga ry’isosiyete mu nganda. Yongera ubushobozi bwo guhangana ku isoko.
Byongeye kandi, pompe ya SLDT series BB4 multi-stage centrifugal yakozwe kandi igategurwa n'uruganda rwa Dalian rwa Liancheng Group yakoreshejwe mu buryo butandukanye mu mushinga wo guteka wa Shanxi Lubao Group Co., Ltd. kugira ngo ishyigikire pompe y'amazi yo gushyushya imyanda (ubushyuhe bw'amazi yo gushyushya T=158℃), na pompe y'amazi yo gushyushya imyanda yo gushyushya Cathay Zhongke Clean The waste heat boiler (ubushyuhe bw'amazi yo gushyushya T=120-130℃) n'indi mishinga y'ubuhanga mu mushinga wo kubyaza ingufu wa Energy Technology Co., Ltd.
Muri make, hashingiwe ku gitekerezo cy’iterambere ryita ku bidukikije, gahunda nziza, imicungire myiza, gukomeza guha abakiriya serivisi zo mu rwego rwo hejuru, gukorana n’abakiriya kugira ngo bakore ingufu zisukuye, zidafite karuboni nyinshi, zitekanye kandi zinoze, gukomeza gufata inzira yo guteza imbere ingufu nziza, no gukomeza gukora imishinga myiza idafite karuboni nyinshi. Ni intego n’intego bidahinduka by’uruganda rwa Dalian rwa Liancheng Group.
