ʻO ka Rupsha 800MW Combined Cycle Power Plant Project (Khulna) ka papahana EPC nui loa ma Bangladesh.Aia ma Khulna City, Bangladesh, he 7.7 kilomita wale nō ka mamao mai ke kūlanakauhale ʻo Khulna.
ʻO ka mea hoʻopukapuka kālā a me ka mea nona ka Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), a ʻo ka EPC general contractor ka consortium o Shanghai Electric Group Co., Ltd. (SEC) a me Ansaldo (AEN) o Italia, a me Fujian Yongfu Electric. Power Design Co., Ltd. (YONGFU) No ka anaina papahana a me ka wae hoʻolālā.ʻO ka 800MW kinoea turbine hui pū ʻia ka mana hoʻokele mana ma Bangladesh Rupusha e loaʻa ana ʻelua "F" -class (Alstom GT26) turbine kinoea, ʻelua mau mea hoʻoheheʻe kinoea, ʻelua pahu wela wela, ʻelua mau pahu hoʻoheheʻe ea hoʻoluʻu pololei a me ʻelua mau mea hoʻoheheʻe mokumahu.Hoʻohana ka mea mana i ke kinoea maoli ma ke ʻano he wahie nui a me ka HSD kiʻekiʻe kiʻekiʻe ma ke ʻano he wahie hoʻihoʻi.Hoʻouna ʻia ka mana o ka mea mana ma waho o ka laina me 230kV mau puka lou a hoʻopili ʻia i ka substation hema o PGCB National Grid Khulna.
Hoʻohana ʻia ka pauma wai hānai OTC o ka 800MW kinoea turbine hui pū ʻia o ka mana uila ma Bangladesh Rupusha no ka hoʻolako ʻana i ka wai i ka turbine gas OTC a no ka hāʻawi ʻana i ka wai desuperheating i ka OTC desuperheater a me ka mea hoʻemi kaomi (e nānā i ke Kiʻi 3).ʻElua mau ʻāpana i ka huina, ua hoʻolako ʻia kēlā me kēia ʻāpana me 2 100% mana OTC feedwater pumps, hoʻokahi e holo ana a me kekahi standby.Ka inoa waena o ka lawe ʻana: OTC wai wai;PH waiwai: 9.2 ~ 9.6;paakiki: 0mmol/l;conductivity: ≤ 0.3ms/cm;maʻiʻo oxygen: ≤ 7mg/l;ion hao: ≤ 20 mg/l;nā iona keleawe:≤ 5mg/l;Loaʻa i ka silicon dioxide: ≤ 20mg/l.
Ma ka hana o ke kaapuni hui o ka hui, komo ka wai hānai mai ka ʻōpala wela (HRSG) kiʻekiʻe-press economizer i ke kiʻekiʻe-press OTC, a me ka wela i hoʻokuʻu ʻia e ka ea wela i hoʻihoʻi ʻia e komo i ka ʻōnaehana kahe wai-mahu.
Pono ka paila wai hānai OTC e hoʻokō i nā kūlana hana like ʻole o ka turbine gas OTC.I ka holo ʻole ʻana o ka pauma holo, hiki ke hoʻokomo maʻalahi i ka pamu kū.I mea e hoʻokō ai i nā koi kūikawā o ka hoʻomaka ʻana, ka pani ʻana a me nā kūlana hoʻāʻo, hiki ke hoʻohana lima ʻia ma ka pūnaewele, a ua hoʻolako ʻia me kahi DCS remote control interface i loko o ka lumi hoʻokele unit.
Ua kūʻai ʻia nā 4 OTC feedwater pumps ma ka 800MW gas turbine combined cycle power station ma Rupsha, Bangladesh e Shanghai Electric Group Co., Ltd. (SEC) ma o ka bidding.Ma hope o nā pōʻai he nui o ke kamaʻilio ʻenehana, wikiō Q&A, a me nā kūkākūkā ʻoihana, ua lilo lākou i hui.ʻO ka SLDT multi-stage centrifugal pump i hoʻolālā ʻia a hoʻomohala ʻia e ka mea kanu Dalian ua hoʻolaha i kāna koho lanakila.
Ke hoʻohana nei ka paila wai hānai OTC i ka API610-BB4 ʻelua-hopena e kākoʻo ana i ka pūpū hoʻokahi-radially split horizontal multi-stage centrifugal pump i hoʻolālā ʻia e ka mea kanu Dalian o Liancheng Group.ʻO kāna kumu hoʻohālike ʻo SLDT80-260D × 9 multi-stage centrifugal pump.
ʻO ka pā wai wai hānai OTC, pili ka hana o kēia pauma keʻena i ka palekana o ka hāmeʻa holoʻokoʻa, a kiʻekiʻe loa nā koi no ka palekana a me ke kūpaʻa.
No nā puna wai hānai OTC, ʻo ka mea mua e noʻonoʻo ai ʻo ia ke ʻano kiʻekiʻe, oʻo, palekana a me ka hilinaʻi o ka paila, a me nā hoʻololi ʻenehana hohonu, koi ʻia nā kūkākūkā a me nā noiʻi.ʻO ka pauma wai hānai OTC ka mea koʻikoʻi o 800MW kinoea turbine hui pū hoʻokele mana.Ma ke koho wale ʻana i nā mea hoʻolako maikaʻi loa a me ka hoʻolālā maikaʻi ʻana a me ka ʻenehana hana e hiki ai ke hōʻoia i ka hoʻomau ʻana o ka hana mana, ka hoʻonui ʻana i nā pono ʻoihana a me ka holo lōʻihi o 800MW gas turbine power station.
ʻO ka kūleʻa kūleʻa o ka ʻOTC feedwater pump no Rupsha 800MW gas turbine combined cycle power station in Bangladesh e hōʻike ana ua ʻike piha ʻia ka ʻoihana ʻo OTC feedwater pump ma ke kahua o ka hoʻomohala ʻana i ke kinoea e nā mea kūʻai aku no kona hoʻomaikaʻi ʻana i ka ikaika, a hoʻohui hou ʻia. ke alakaʻi ʻenehana o ka hui ma ka ʻoihana.Hoʻonui i ka hoʻokūkū mākeke.
Eia kekahi, ua hoʻohana ʻia ka SLDT series BB4 multi-stage centrifugal pump i hoʻolālā ʻia e ka lāʻau Dalian o Liancheng Group i ka hana coking o Shanxi Lubao Group Co., Ltd. (ka wela wai paila T=158 ℃), a me Cathay Zhongke Maʻemaʻe ʻO ka ʻōpala wela wela e hānai ai i ka paila wai (ka wela wai paila T=120-130 ℃) a me nā papahana ʻenekinia ʻē aʻe i ka papahana hana mana o Energy Technology Co., Ltd.
I ka pōkole, ma muli o ka manaʻo o ka'ōmaʻomaʻo ulu, meticulous hui, lean hooponopono, e hoʻomau i ka hoʻolako 'ana i nā mea kūʻai mai me ka mua-papa lawelawe, hana me nā mea kūʻai mai e hana maʻemaʻe, haʻahaʻa-carbon, palekana a me ka efficient ikehu, e hoʻomau i ke ala o kiʻekiʻe. -ʻoi aku ka maikaʻi o ka ikehu, a hoʻomau i ka hana ʻana i nā papahana ʻōmaʻomaʻo maʻemaʻe kiʻekiʻe, haʻahaʻa-carbon ʻO ia ka pahuhopu ʻole a me ke kumu o ka lāʻau Dalian o Liancheng Group.
