ʻO ka Papahana Mana Hoʻohuihui Hui Pū ʻIa ʻo Rupsha 800MW (Khulna) ka papahana EPC hale hana mana turbine kinoea hoʻokahi nui loa ma Bangladesh. Aia ma ke kūlanakauhale ʻo Khulna, Bangladesh, he 7.7 kilomita wale nō ka mamao o ke kahua mai ke kūlanakauhale ʻo Khulna.
ʻO ka mea hoʻopukapuka kālā a me ka mea nona ʻo Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), a ʻo ka ʻoihana hana laulā EPC ʻo ia ka hui 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 ʻāpana anamanaʻo a me ka hoʻolālā papahana.ʻO ka papahana kikowaena mana hui pū ʻia o ka turbine kinoea 800MW ma Bangladesh Rupusha e komo pū ana me ʻelua mau turbine kinoea papa "F" (Alstom GT26), ʻelua mau mea hana turbine kinoea, ʻelua mau paila wela ʻōpala, ʻelua mau turbine mahu hoʻomaʻalili ea pololei a me ʻelua mau mea hana turbine mahu. Hoʻohana ka hale hana mana i ke kinoea kūlohelohe ma ke ʻano he wahie nui a me ka diesel HSD wikiwiki kiʻekiʻe ma ke ʻano he wahie kākoʻo. Hoʻouna ʻia ka mana o ka hale hana mana ma waho o ka laina me nā loop pālua 230kV a hoʻopili ʻia i ka substation hema o PGCB National Grid Khulna.
Hoʻohana ʻia ka pamu wai hānai OTC o ke kahua mana hui pū ʻia o ka turbine kinoea 800MW ma Bangladesh Rupusha no ka hoʻolako wai mau i ka turbine kinoea OTC a no ka hoʻolako ʻana i ka wai desuperheating i ka desuperheater OTC a me ka mea hoʻēmi kaomi (e nānā i ke Kiʻi 3). ʻElua mau ʻāpana i ka huina, ua lako kēlā me kēia ʻāpana me 2 mau pamu wai hānai OTC 100% ka mana, hoʻokahi e holo ana a ʻo kekahi e kali ana. Inoa waena hāʻawi: lako wai OTC; waiwai PH: 9.2 ~ 9.6; paʻakikī: 0mmol/l; conductivity: ≤ 0.3ms/cm; ʻike oxygen: ≤ 7mg/l; ions hao: ≤ 20 mg/l; ions keleawe: ≤ 5mg/l; Loaʻa ka silicon dioxide: ≤ 20mg/l.
I ka hana pōʻaiapuni hui pū ʻia o ka ʻāpana, komo ka wai hānai mai ka mea hoʻokele waiwai wela ʻōpala (HRSG) i ka OTC kaomi kiʻekiʻe, a komo ka wela i hoʻokuʻu ʻia e ka ea wela i hoʻōla ʻia i ka ʻōnaehana kaʻapuni mahu-wai.
Pono ka pamu wai hānai OTC e hoʻokō i nā kūlana hana like ʻole o ka turbine kinoea OTC. Ke holo hewa ka pamu e holo ana, hiki ke hoʻokomo ʻia ka pamu kū i ka hana aunoa. 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 kahi, a ua lako pū ʻia me kahi kikowaena mana mamao DCS i loko o ka lumi hoʻomalu o ka ʻāpana.
Ua kūʻai ʻia nā pamu wai hānai OTC 4 ma ke kahua mana paikikala hui kinoea 800MW ma Rupsha, Bangladesh e Shanghai Electric Group Co., Ltd. (SEC) ma o ke kūʻai ʻana. Ma hope o nā pōʻai he nui o ke kamaʻilio loea, wikiō Q&A, a me nā kūkākūkā ʻoihana, ua lilo hope lākou i hui. Ua hoʻolaha ka pamu centrifugal multi-stage SLDT i hoʻolālā ʻia a hoʻomohala ʻia e ka hale hana ʻo Dalian i kāna kūʻai lanakila.
Hoʻohana ka pamu wai hānai OTC i ka pamu centrifugal multi-stage horizontal ʻelua-ʻaoʻao e kākoʻo ana i ka pūpū hoʻokahi i hoʻokaʻawale ʻia me ka radially i hoʻolālā ʻia a hoʻomohala ʻia e ka hale hana Dalian o Liancheng Group. ʻO kāna kumu hoʻohālike he pamu centrifugal multi-stage SLDT80-260D × 9.
ʻO ka pamu wai hānai OTC, pili ka hana o kēia pamu kikowaena i ka palekana o ka hāmeʻa holoʻokoʻa, a kiʻekiʻe loa nā koi no ka palekana a me ke kūpaʻa.
No nā pamu wai hānai OTC, ʻo ka mea mua e noʻonoʻo ai, ʻo ia ke ʻano holomua, ka oʻo ʻana, ka palekana a me ka hilinaʻi o ka pamu, a me nā hoʻololi loea hohonu, nā kūkākūkā a me nā noiʻi e pono ai. ʻO ka pamu wai hānai OTC nā lako koʻikoʻi o ke kahua mana pōʻaiapuni hui turbine kinoea 800MW. Ma ke koho ʻana i nā mea hoʻolako maikaʻi loa a me ka hoʻolālā a me ka ʻenehana hana i hoʻomaikaʻi ʻia hiki ke hōʻoia i ka hana mau o nā lako mana, ka hoʻonui ʻana i nā pono o nā ʻoihana a me ke kaʻina hana lōʻihi o ka holo ʻana o ke kahua mana turbine kinoea 800MW.
ʻO ke kūʻai kūleʻa ʻana o ka pamu wai hānai OTC no ke kahua mana hui pū ʻia o ka turbine kinoea ʻo Rupsha 800MW ma Bangladesh e hōʻike ana ua ʻike piha ʻia ka pamu wai hānai OTC o ka hui ma ke kahua o ka hana mana kinoea e nā mea kūʻai aku no kona hoʻomaikaʻi piha ʻana i ka ikaika, a ua hoʻopaʻa hou i ke alakaʻi ʻenehana o ka hui ma ka ʻoihana. Hoʻonui i ka hoʻokūkū mākeke.
Eia kekahi, ua hoʻohana mau ʻia ka pamu centrifugal multi-stage SLDT series BB4 i hoʻolālā ʻia a hoʻomohala ʻia e ka hale hana Dalian o Liancheng Group i ka papahana coking o Shanxi Lubao Group Co., Ltd. e kākoʻo i ka pamu wai hānai paila wela maloʻo (mahana wai paila T = 158 ℃), a me Cathay Zhongke Clean The neoneo wela boiler feed water pump (mahana 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 ke kumumanaʻo o ka hoʻomohala ʻōmaʻomaʻo, ka hoʻonohonoho pono, ka hoʻokele lean, e hoʻomau i ka hāʻawi ʻana i nā mea kūʻai aku me nā lawelawe papa mua, e hana pū me nā mea kūʻai aku e hana i ka ikehu maʻemaʻe, haʻahaʻa-kalapona, palekana a me ka pono, e hoʻomau i ke ala o ka hoʻomohala ikehu kiʻekiʻe, a e hoʻomau i ka hana ʻana i nā papahana ʻōmaʻomaʻo maʻemaʻe kiʻekiʻe, haʻahaʻa-kalapona. ʻO ia ka pahuhopu a me ke kumu paʻa o ka hale hana Dalian o Liancheng Group.
