Ko te Rupsha 800MW Combined Cycle Power Plant Project (Khulna) ko te kaupapa EPC hiko hiko hiko hiko kotahi i Bangladesh.Kei te taone o Khulna, Bangladesh, ko te waahi kei te 7.7 kiromita noa te tawhiti atu i te taone o Khulna.
Ko te kaipupuri moni me te rangatira ko Bangladesh Northwest Power Generation Co., Ltd. (NWPGCL), a ko te Kaikirimana whanui EPC te roopu o Shanghai Electric Group Co., Ltd. (SEC) me Ansaldo (AEN) o Itari, me Fujian Yongfu Electric Power Design Co., Ltd. (YONGFU) Mo te rangahau kaupapa me te waahanga hoahoa.Kei roto i te kaupapa teihana hiko hiko 800MW i Bangladesh Rupusha e rua nga kapohau hau "F" -class (Alstom GT26), e rua nga kaikohikohiko hiko, e rua nga kohua wera ururua, e rua nga miihini hiko whakamahana-a-rangi me nga kaihanga miihini mamaoa e rua.Ka whakamahia e te tipu hiko te hau maaori hei wahie matua me te HSD tere-tiketike hei wahie whakaora.Ko te mana o te tipu hiko ka tukuna mai i te raina me te 230kV rua nga koropiko, ka hono atu ki te taha tonga o te PGCB National Grid Khulna.
Ko te papu wai whangai OTC o te 800MW kapohau hau whakakotahi i te teihana hiko huringa i Bangladesh Rupusha e whakamahia ana mo te tuku wai tonu ki te miihini hiko OTC me te whakarato wai whakamahana ki te OTC desuperheater me te whakaheke pehanga (tirohia te Whakaahua 3).E rua nga waahanga katoa, ko ia waahanga he 2 100% te kaha o nga papu wai whangai OTC, kotahi e rere ana me tetahi atu e tatari ana.Ingoa Waenga Tukunga: Te tuku wai OTC;Uara PH: 9.2~9.6;pakeke: 0mmol/l;te kawe: ≤ 0.3ms/cm;ihirangi hāora: ≤ 7mg/l;katote rino: ≤ 20 mg/l;katote parahi:≤ 5mg/l;Kei roto i te hauhā hauhā: ≤ 20mg/l.
I roto i te mahinga huringa whakakotahi o te waeine, ka uru te wai whangai mai i te kohu wera para (HRSG) ohaoha pehanga teitei ki te OTC pehanga nui, me te wera i tukuna e te hau wera whakaora ka uru ki te punaha tohanga wai-mamao.
Ko te papu wai whangai OTC e hiahiatia ana ki te whakatutuki i nga ahuatanga whakahaere o te OTC turbine hau.A, no te haere pohehe te papu rere, ka taea te mahi aunoa i te papu tūtatari.Hei whakatutuki i nga whakaritenga motuhake o te tiimata, te kati me nga tikanga whakamatautau, ka taea te whakahaere-a-ringa i runga i te waahi, ka whakauruhia ki te atanga mana mamao DCS i roto i te ruma whakahaere wae.
Ko nga papu wai whangai OTC e 4 i roto i te teihana hiko hiko 800MW i Rupsha, Bangladesh i hokona e Shanghai Electric Group Co., Ltd. (SEC) ma te tuku tono.Whai muri i nga huringa maha o te whakawhitiwhiti korero hangarau, te ataata Q&A, me nga whiriwhiringa pakihi, i te mutunga ka noho hei roopu.Ko te papu SLDT maha-waahanga centrifugal i hangaia, i whakawhanakehia e te tipu Dalian kua panui tana tono toa.
Ko te papu wai whangai OTC e whakamahi ana i te API610-BB4 e rua-mutunga e tautoko ana i te anga kotahi e wehea ana te papu porotiti maha-waahanga whakapae i hangaia, i whakawhanakehia e te tipu Dalian o Liancheng Group.Ko tana tauira ko te SLDT80-260D × 9 maha-waahanga papu centrifugal.
Ko te papu wai whangai OTC, ko te mahi o tenei papu teihana e pa ana ki te haumaru o te taputapu katoa, me nga whakaritenga mo te haumaru me te pumau he tino tiketike.
Mo nga papu wai whangai OTC, ko te mea tuatahi ki te whakaaro ko te ahua matatau, te pakeketanga, te haumaru me te pono o te papu, me nga whakawhitinga hangarau hohonu, me whai korero me nga tirotirohanga.Ko te papu wai whangai OTC te taputapu matua o te teihana hiko hiko 800MW hiko hiko.Ma te whiriwhiri i nga kaiwhakarato tino pai me te hoahoa hoahoa me te hangarau whakangao ka taea te whakarite i te mahi tonu o nga taputapu hiko, te whakanui ake i nga hiahia umanga me te huringa roa o te 800MW teihana hiko hiko hiko.
Ko te tuku angitu o te papu wai whangai OTC mo te Rupsha 800MW hiko hiko hiko hiko i Bangladesh e tohu ana ko te papu wai whangai OTC a te kamupene i roto i te mara o te whakangao hiko puhipuhi hau kua tino mohiohia e nga kaihoko mo tona kaha ake o te kaha, me te whakakotahi ano. te kaiarahi hangarau o te kamupene i roto i te umanga.Whakanuia te whakataetae maakete.
I tua atu, ko te SLDT raupapa BB4 maha-waahanga papu centrifugal hangaia me te whakawhanakehia e te tipu Dalian o Liancheng Group kua karu i whakamahia i roto i te kaupapa coking o Shanxi Lubao Group Co., Ltd. ki te tautoko i te maroke tinei ururua wera kōhua whāngai papu wai. (te pāmahana wai kōhua T=158 ℃), me te Cathay Zhongke Clean Ko te parapara wera wera wai whangai papu wai (kohua wai pāmahana T=120-130 ℃) me etahi atu kaupapa hangarau i roto i te kaupapa hanga hiko o Energy Technology Co., Ltd.
I roto i te poto, i runga i te ariā o te whanaketanga matomato, whakahaere ātaahua, whakahaere hiroki, tonu ki te whakarato kiritaki ki te ratonga tuatahi-akomanga, mahi ki te kiritaki ki te hanga ma, iti-waro, haumaru me te pai pūngao, haere tonu ki te tango i te huarahi o tiketike. -Ko te whakawhanaketanga o te kaha o te kounga, me te hanga tonu i nga kaupapa kaakaariki ma te kounga teitei, iti-waro Ko te whaainga me te kaupapa o te tipu Dalian o Liancheng Group.
