Igicuruzwa:SA210 Grade A-1 (ASTM A210/ASME SA210) ifite umuyoboro w'icyuma giciriritse cya karuboni gifite amashami menshi - imbere gifite imigozi izunguruka ku buso bw'imbere. Yakozwe no gukurura ubukonje hejuru y'icyuma cyabugenewe gifite imbunda. Yagenewe inkuta z'amazi za boiler zifite umuvuduko mwinshi (ibipimo by'ubushyuhe bukabije n'ubushyuhe burenze 300.000 KW). Imbunda y'imbere itera imbaraga zitandukanya amazi n'umwuka, igatera amazi ku rukuta rw'umuyoboro kugira ngo ikomeze kubira no gukumira firime y'umwuka.
Amagambo y'ingenzi:Umuyoboro wa SA210 ufite imbunda, umuyoboro udafite umugozi wa SA210 wo mu cyiciro cya A-1, umuyoboro wa boiler ufite imbunda nyinshi, umuyoboro ufite imbanda imbere, umuyoboro ukozwe mu imbunda ukonje, umuyoboro w'amazi, umuyoboro ukozwe mu imbunda, umuyoboro wa boiler wa ASME SA210, umuyoboro ukozwe mu imbunda ukonje wa SA210 wo mu cyiciro cya A-1, umuyoboro wa boiler ukora neza cyane, urukuta rw'amazi rwa boiler rufite imbunda, uruganda rukora imiyoboro ifite imbunda, utanga imiyoboro ifite imbunda mu Bushinwa
Icyitonderwa ku mvugo:"Umuyoboro w'amasasu" na "umuyoboro w'amasasu imbere" bivuga ikintu kimwe. Amagambo yombi asobanura imiyoboro idafite umugozi ifite imbavu zizunguruka zikozwe ku buso bw'imbere bukonje bukurura hejuru y'umuyoboro urimo imiyoboro. abantu benshi bayoboraInyito igaragaza imbavu nyinshi zifatanye (ubusanzwe 4 cyangwa 6 zitangira) zigenda ku burebure bw'umuyoboro.
1. Ibikoresho by'ibanze: SA210 Grade A-1 Seamless Medium-Carbon Steel
ASTM A210/ASME SA210 ni yo mabwiriza asanzwe agenga boiler y'icyuma gishyushya ikoze muri karuboni idafite umugozi n'imiyoboro ishyushya cyane. Aya mabwiriza akubiyemo imiyoboro y'icyuma ifite ubugari buke bw'inkuta ku miyoboro ishyushya, harimo impera z'umutekano, imiyoboro ipfundikiye, imiyoboro igumaho, n'imiyoboro ishyushya cyane. SA210 Grade A-1 ni yo mabwiriza akoreshwa cyane muri serivisi rusange y'imiyoboro ishyushya, itanga uburinganire bwiza bw'imbaraga, ubushobozi bwo kugenda, n'igiciro.
Ku bijyanye n'umuvuduko mwinshi n'ubushyuhe bwinshi, SA210 Grade C (ifite karuboni nyinshi, imbaraga nyinshi) irahari. Ariko, Grade A-1 iracyari igipimo ngenderwaho cy'inganda mu gukoresha inkuta z'amazi zisaba ubushobozi bwo gukora neza kugira ngo zikonje kandi zikore neza ku bushyuhe bw'icyuma kugeza kuri 425°C (800°F).

Imiyoboro isanzwe ifite imbunda nyinshi igizwe n'ubwoko bubiri (Ubwoko bwa A n'Ubwoko bwa B) ifite inguni ya dogere 30. Imiyoboro ifite imbunda nyinshi ikozwe neza ishobora kugira inguni ya helix igera kuri 40°+, itanga inyungu yiyongereyeho 20% mu mikoreshereze y'ubushyuhe ugereranije n'imiyoboro isanzwe ifite imbunda.
Amakuru y'ubushakashatsi:Umuyoboro w'imbunda ufite imbavu 4, umurambararo wo hanze wa mm 25, uburebure bw'imbavu bwa mm 0.68, ubugari bw'imbavu bwa mm 9.25, n'inguni ya helix ya 60°, byemejwe mu igerageza. Ubushakashatsi bw'imibare bwemeza ko imiterere y'imiyoboro ifite imbavu z'urukiramende nziza ifite imbavu z'urukiramende (uburebure bwa mm 0.775, inguni za helix za 30° na 58°) yongera urujya n'uruza rw'insinga hafi y'urukuta rw'umuyoboro, birushaho kunoza cyane uburyo bwo kohereza ubushyuhe.
Kongera ubuso bw'ubuso:Ubuso bw'imbere kuri buri gice cy'uburebure bw'imiyoboro y'imbere ifite imbavu ni inshuro zigera kuri 1.5 kugeza kuri 2.4 z'imiyoboro yoroshye ifite umurambararo umwe wo hanze. Uburyo bwo gushushanya bukonje butuma urukuta rw'imbere ruhinduka imiterere y'imiyoboro ifite imbavu ifite ingano nyayo, byongera cyane ubuso bw'umuyoboro butanga ubushyuhe ugereranije n'imiyoboro yambaye ubusa.

3. Uburyo bwo gukora - Gushushanya hakoreshejwe icyuma gikonjesha
Womic Steel ikora imiyoboro ya boiler ifite umugozi mwinshi ya SA210 Grade A-1 ikoresheje uburyo bwo gushushanya bukonje neza hamwe n'icyuma gifunganye kizunguruka. Uburyo butangirira ku gikoresho cy'umuyoboro gifite umugozi ushyushye, kikaba ari cyo gikoresho cyo gutangira gukora ibikorwa byo gushushanya ubukonje bikurikira. Nyuma yo gushushanya ubukonje bwa mbere hakoreshejwe icyuma gifunganye kugira ngo kigere ku bipimo bito, igikorwa cya nyuma cyo gushushanya gikoresha icyuma gifite umugozi munini.
Igikoresho cyabugenewe (gikozwe mu buryo bwa helical) gishyirwa mu muyoboro w'icyuma kigahambirwa ku gikoresho kizunguruka. Umuyoboro unyuzwa mu cyuma gifasha kugabanya ingufu, kandi uko umuyoboro ugenda uzamuka imbere, umuyoboro urazenguruka, ugakora imbavu nyinshi zihoraho ku buso bw'imbere. Igice cy'umuyoboro gifite imiyoboro yo hanze ingana ku ruhande rw'imbere, hamwe n'ubutaka bwo hanze busimburana hagati y'imiyoboro. Iyo umuyoboro ushyizwe hejuru y'uyu muyoboro urimo imiyoboro, ubutaka bushyira imiterere y'uruziga igenzurwa—ubusanzwe imbavu 4 cyangwa 6 zigororotse—ku rukuta rw'imbere rw'umuyoboro, mu gihe imiyoboro yemerera icyuma gisohoka gutembera.
Uburyo bwo kwigana imibare bugezweho (Finite Element Method, FEM) bukoreshwa mu kunoza imiterere y’ibice mbere yuko umusaruro utangira, bigabanye inenge zo mu rukuta rw’imiyoboro y’amashanyarazi n’uturemangingo. Ibyiza by’ingenzi by’iyi gahunda birimo imiterere y’imbavu ihamye, umusaruro mwinshi, igihe kirekire cy’ibikoresho, imiterere y’imbavu ihoraho, no kurangiza neza imbere. Igipimo cya nyuma kigerwaho ni ugukurura ubukonje kuri OD na WT nyayo, gushyushya neza (guhinduka bisanzwe), no kugenzura 100% NDT.
4. Uburyo bwo kongera ubushyuhe - Impamvu imiyoboro y'amasasu ikora
Mu miyoboro y'amazi yoroshye, utubumbe tw'umwuka duhurira ku buso bw'imbere, bigatuma habaho firime y'umwuka ikomeza. Iyi firime y'umwuka ni igikoresho kibi cy'ubushyuhe, bigatuma imikorere y'ubushyuhe igabanuka cyane kandi ishobora gutera ubushyuhe bwinshi no kwangirika kw'imiyoboro (kuva mu kubirira kwa nucleate, cyangwa DNB).
Imiyoboro ifite imbunda ikemura iki kibazo binyuze mu gutera imbaraga za centrifugal mu muyoboro, ikasunika amazi y'amazi yerekeza ku rukuta rw'umuyoboro mu gihe umwuka werekeza hagati. Ubu buryo butanga inyungu enye z'ingenzi:
Guhagarika DNB— urwego rw'amazi ku rukuta rutuma imiterere y'amazi ikomeza kubira nubwo haba hari ubushyuhe bwinshi.
Kuma bitinze— mu bihe bigoye cyane, gukoresha imbunda byongera igihe cyo kuma, bikingira ubusugire bw'imiyoboro.
Ubwinshi bw'ubushyuhe bukabije— kubira kwa nucleate bigumana ubushyuhe bwinshi cyane.
Kongera ubushobozi bwo kohereza ubushyuhe— nubwo haba hari ubushyuhe buke, umuyoboro w’amazi utuma ubushyuhe burushaho kwiyongera cyane, ariko ukagabanya ubushyuhe bukenewe kugira ngo ubukonje bube buhagije.
Inyigo za CFD zigaragaza ko kunoza ibipimo bya geometrike—harimo umubare w'imitako y'imbunda, uburebure bw'imbavu, n'uburebure bw'umuvuduko w'imbunda—bishobora kongera uburyo ubushyuhe butwara burenga imiterere y'ibanze y'imbunda. Umuvuduko w'amazi uturuka ku mbavu za helical ukora agace gato k'amazi ku rukuta, byongera cyane ubushobozi bwo kohereza ubushyuhe ugereranije n'imiyoboro yoroshye.
5. Igenzura ry'Ubuziranenge n'Isuzuma
