Pulojekiti ya Rupsha 800MW Combined Cycle Power Plant (Khulna) ndiye pulojekiti yayikulu kwambiri yamagetsi yamagetsi yamagetsi yamagetsi ya EPC ku Bangladesh. Ili ku Khulna City, Bangladesh, malowa ali pamtunda wa makilomita 7.7 okha kuchokera ku mzinda wa Khulna.
Ogulitsa ndi eni ake ndi Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), ndipo EPC general contractor ndi consortium of Shanghai Electric Group Co., Ltd. (SEC) and Italy's Ansaldo (AEN), and Fujian Yongfu Electric Power Design Co., Ltd. (YONGFU) Pa kafukufuku wa polojekiti ndi kapangidwe kake.Ntchito ya 800MW gasi yophatikiza magetsi ku Bangladesh Rupusha imaphatikizapo makina opangira gasi a "F"-class (Alstom GT26), majenereta awiri a turbine, ma boiler awiri otenthetsera zinyalala, ma turbine awiri achindunji oziziritsidwa ndi mpweya ndi ma jenereta awiri opangira nthunzi. Malo opangira magetsi amagwiritsa ntchito gasi ngati gwero lalikulu lamafuta ndi dizilo lothamanga kwambiri HSD ngati mafuta osungira. Mphamvu yopangira magetsi imatumizidwa kunja kwa mzere ndi 230kV miluko iwiri ndikulumikizidwa ku substation yakumwera ya PGCB National Grid Khulna.
Pampu yamadzi ya OTC ya 800MW gas turbine kuphatikiza magetsi ozungulira ku Bangladesh Rupusha imagwiritsidwa ntchito popereka madzi mosalekeza ku turbine yamafuta OTC komanso kupereka madzi osatentha ku chotenthetsera cha OTC komanso chochepetsera kupanikizika (onani Chithunzi 3). Pali mayunitsi awiri okwana, aliyense unit okonzeka ndi 2 100% mphamvu OTC feedwater mapampu, kuthamanga ndi zina standby. Kutumiza dzina lapakati: Kupereka madzi kwa OTC; Mtengo wa PH: 9.2~9.6; kuuma: 0mmol/l; conductivity: ≤ 0.3ms/cm; mpweya wa okosijeni: ≤ 7mg/l; ayoni chitsulo: ≤ 20 mg/l; ayoni mkuwa: ≤ 5mg/l; Muli silicon dioxide: ≤ 20mg/l.
Pogwiritsa ntchito kagawo kakang'ono ka unit, madzi odyetserako kuchokera ku chimbudzi cha kutentha kwa zinyalala (HRSG) otsika kwambiri amalowa mu OTC yothamanga kwambiri, ndipo kutentha komwe kumatulutsidwa ndi mpweya wotentha wopezekanso kumalowa mu kayendedwe ka madzi a nthunzi.
Pampu yamadzi ya OTC ikufunika kuti ikwaniritse machitidwe osiyanasiyana ogwiritsira ntchito gasi turbine OTC. Pampu yothamanga ikayenda mwangozi, pampu yoyimilirayo imatha kuyikidwa kuti igwire ntchito yokha. Kuti akwaniritse zofunikira zapadera zoyambira, zotsekera ndi zoyeserera, zitha kugwiritsidwa ntchito pamanja pamalopo, ndipo zimakhala ndi mawonekedwe akutali a DCS muchipinda chowongolera ma unit.
Mapampu 4 amadzi a OTC mu 800MW gas turbine kuphatikiza magetsi ozungulira ku Rupsha, Bangladesh adagulidwa ndi Shanghai Electric Group Co., Ltd. (SEC) kudzera pabizinesi. Pambuyo pazokambirana zingapo zaukadaulo, ma Q&A amakanema, ndi zokambirana zamabizinesi, adakhala gulu. Pampu ya SLDT yamitundu yambiri ya centrifugal yopangidwa ndikupangidwa ndi chomera cha Dalian yalengeza kuti idzapambana.
Pampu yamadzi ya OTC imagwiritsa ntchito API610-BB4-mapeto awiri yothandizira chipolopolo chimodzi chogawanika chopingasa chopingasa chamitundumitundu chopangidwa ndikupangidwa ndi chomera cha Dalian cha Liancheng Gulu. Chitsanzo chake ndi SLDT80-260D×9 pampu ya centrifugal yamitundu yambiri.
Pampu yamadzi ya OTC, kugwira ntchito kwa mpope wapa station iyi kumagwirizana ndi chitetezo cha chipangizo chonsecho, ndipo zofunika pachitetezo ndi kukhazikika ndizokwera kwambiri.
Kwa mapampu amadzi a OTC, chinthu choyamba choyenera kuganizira ndi chikhalidwe chapamwamba, kukhwima, chitetezo ndi kudalirika kwa mpope, ndi kusinthana kwakuya kwaukadaulo, kukambirana ndi kufufuza kumafunika. OTC feed water pump ndiye chida chachikulu cha 800MW gasi turbine kuphatikiza magetsi ozungulira. Pokhapokha posankha ogulitsa abwino kwambiri komanso luso lokonzekera bwino komanso luso lopanga zinthu zomwe zingatsimikizidwe kuti zida zamagetsi zizigwiritsidwa ntchito mosalekeza, kukulitsa zokonda zamakampani komanso kuzungulira kwanthawi yayitali kwa 800MW gas turbine power station.
Kuyitanitsa bwino kwa mpope wa OTC feedwater kwa Rupsha 800MW gasi turbine kuphatikiza magetsi ozungulira ku Bangladesh kukuwonetsa kuti pampu yapampu yamadzi ya OTC yamakampani pamakampani opangira magetsi opangidwa ndi gasi yakhala ikudziwika bwino ndi makasitomala chifukwa chakuwongolera kwake kwamphamvu, ndikuphatikizidwanso. utsogoleri waukadaulo wamakampani pamakampani. Limbikitsani kupikisana kwa msika.
Komanso, SLDT mndandanda BB4 Mipikisano siteji centrifugal mpope wopangidwa ndi kupangidwa ndi Dalian chomera Liancheng Gulu wakhala motsatizana ntchito coking ntchito ya Shanxi Lubao Group Co., Ltd. (boiler madzi kutentha T=158 ℃), ndi Cathay Zhongke Clean The zinyalala kutentha kukatentha madzi pompa madzi (boiler madzi kutentha T=120-130℃) ndi ma projekiti ena aumisiri mu projekiti yopangira magetsi ya Energy Technology Co., Ltd.
Mwachidule, potengera lingaliro la chitukuko chobiriwira, bungwe losamala, kasamalidwe kotsamira, pitirizani kupereka makasitomala ndi mautumiki apamwamba, kugwira ntchito ndi makasitomala kuti apange mphamvu zoyera, za carbon, zotetezeka komanso zogwira mtima, pitirizani kutenga msewu wapamwamba. -chitukuko champhamvu champhamvu, ndikupitiriza kupanga mapulojekiti apamwamba a ukhondo, otsika kwambiri a carbon Ndi cholinga chosasintha ndi cholinga cha chomera cha Dalian cha Liancheng Group.
