Umushinga wa Rupsha 800MW Uhurijwe hamwe n’umushinga w’amashanyarazi (Khulna) niwo mushinga munini wa gazi ya turbine y’amashanyarazi EPC muri Bangladesh. Ikibanza giherereye mu mujyi wa Khulna, muri Bangaladeshi, ni kilometero 7.7 gusa uvuye mu mujyi wa Khulna.
Umushoramari na nyir'ubwite ni Bangladesh ya Northwest Power Generation Co., Ltd. (NWPGCL), naho umushoramari 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) Kubushakashatsi bwumushinga no gushushanya.800MW ya gaz turbine ikomatanya umushinga w'amashanyarazi muri Bangladesh Rupusha ikubiyemo turbine ebyiri za “F” -class (Alstom GT26), amashanyarazi abiri ya gaz turbine, ibyuma bibiri bishyushya imyanda, ibyuma bibiri bikonjesha ikirere hamwe na moteri ebyiri. Urugomero rw'amashanyarazi rukoresha gaze karemano nkibicanwa nyamukuru na mazutu yihuta ya mazutu HSD nkibicanwa byinyuma. Imbaraga z'urugomero rw'amashanyarazi zoherejwe hanze y'umurongo hamwe na 230kV zibiri kandi zihuzwa na sitasiyo y'amajyepfo ya PGCB National Grid Khulna.
OTC igaburira amazi ya pompe ya 800MW ya gaz turbine ikomatanya amashanyarazi muri Bangladesh Rupusha ikoreshwa mugutanga amazi ahoraho kuri turbine ya gaz OTC no gutanga amazi yangiza kuri OTC desuperheater no kugabanya umuvuduko (reba Ishusho 3). Hariho ibice bibiri byose hamwe, buri gice gifite ubushobozi bwa 2 100% pompe yamazi yo kugaburira OTC, imwe ikora nindi ihagaze. Gutanga izina rito: OTC itanga amazi; Agaciro PH: 9.2 ~ 9.6; gukomera: 0mmol / l; imiyoboro: ≤ 0.3ms / cm; umwuka wa ogisijeni: ≤ 7mg / l; ion ion: ≤ 20 mg / l; ion z'umuringa ： ≤ 5mg / l; Harimo dioxyde ya silicon: ≤ 20mg / l.
Mubikorwa bikomatanyirijwe hamwe, amazi yo kugaburira ava mumashanyarazi (HRSG) yumuvuduko ukabije wubukungu winjira muri OTC yumuvuduko mwinshi, kandi ubushyuhe bwasohowe numwuka ushushe wagaruwe bwinjira muri sisitemu yo kuzenguruka amazi.
Amazi yo kugaburira OTC asabwa kugira ngo yuzuze imikorere itandukanye ya gaz turbine OTC. Iyo pompe ikora igenda kubwimpanuka, pompe ihagaze irashobora gukoreshwa muburyo bwikora. Kugirango wuzuze ibisabwa byihariye byo gutangira, guhagarika no kugerageza ibizamini, birashobora gukorerwa intoki kurubuga, kandi bifite ibikoresho bya DCS bigenzura kure mubyumba bigenzura.
Amapompo 4 ya OTC muri pompe ya 800MW ya turbine ihuriweho na sitasiyo y’amashanyarazi i Rupsha, muri Bangladesh yaguzwe na Shanghai Electric Group Co., Ltd. (SEC) binyuze mu gupiganira amasoko. Nyuma yuburyo bwinshi bwo gutumanaho tekinike, videwo Q&A, nu biganiro byubucuruzi, amaherezo babaye itsinda. SLDT ibyiciro byinshi bya centrifugal pompe yateguwe kandi itunganijwe n uruganda rwa Dalian yatangaje isoko ryatsindiye.
Amazi yo kugaburira OTC akoresha API610-BB4 impande zombi zishyigikira igishishwa kimwe kigabanyijemo ibice bibiri bya centrifugal pompe yateguwe kandi ikorwa n uruganda rwa Dalian rwitsinda rya Liancheng. Icyitegererezo cyayo ni SLDT80-260D × 9 ibyiciro byinshi bya pompe ya centrifugal.
OTC igaburira amazi ya pompe, imikorere yiyi pompe ijyanye numutekano wigikoresho cyose, kandi ibisabwa mumutekano no gutuza ni byinshi cyane.
Kuri pompe y'amazi ya OTC, ikintu cya mbere ugomba gusuzuma ni kamere yateye imbere, gukura, umutekano no kwizerwa bya pompe, kandi harasabwa guhanahana byimbitse tekinike, kugisha inama no gukora iperereza. Amazi ya pompe ya OTC nibikoresho byingenzi bya 800MW ya gaz turbine ihuriweho na sitasiyo yamashanyarazi. Gusa muguhitamo abatanga isoko nziza hamwe nuburyo bunoze bwo gukora no gukoresha ikoranabuhanga birashobora gukorwa neza kugirango ibikoresho byingufu bikomeze gukorwa neza, inyungu zinyungu hamwe nigihe kirekire cyumuriro wa 800MW gazi ya turbine ikora.
Isoko ryiza rya pompe y'amazi ya OTC kuri Rupsha 800MW ya turbine ya gazi ihuriweho na sitasiyo y’amashanyarazi muri Bangladesh yerekana ko pompe y’amazi y’ibiryo ya OTC mu bijyanye n’amashanyarazi akoreshwa na gaze yamenyekanye neza n’abakiriya kubera ko yazamuye imbaraga zuzuye, kandi ikomeza gushimangirwa ubuyobozi bw'ikoranabuhanga mu ruganda. Kongera ubushobozi bwo guhangana ku isoko.
Byongeye kandi, SLDT ikurikirana ya BB4 ibyiciro byinshi bya centrifugal pompe yateguwe kandi itunganijwe n uruganda rwa Dalian rwo muri Liancheng Group rwagiye rukoreshwa mumushinga wa kokiya wa Shanxi Lubao Group Co., Ltd. kugirango ushyigikire imyanda yumuriro wumye (ubushyuhe bwamazi ya Tiler 15 = umushinga wo kubyara ingufu za Technology Technology, Ltd.
Muri make, hashingiwe ku gitekerezo cyiterambere ryicyatsi, ishyirahamwe ryitondewe, gucunga ibinure, komeza guha abakiriya serivisi zo mucyiciro cya mbere, gukorana nabakiriya kugirango habeho ingufu zisukuye, karuboni nkeya, umutekano kandi neza, komeza ufate inzira ndende -terambere ryingufu zingana, kandi ukomeze gukora imishinga yo mu rwego rwohejuru isukuye, karuboni nkeya Nicyerekezo nintego bidahinduka byuruganda rwa Dalian rwitsinda rya Liancheng.
