Uruhu rwa oxyde ya supercritical circular fluidized bed boiler bivuga uruhu rwa oxyde yububyimba runaka bwakozwe nyuma ya firime ya okiside igenda yoroha nyuma yo guteka ikora igihe kirekire, kandi akenshi usanga hariho itandukaniro rinini muburyo bwo kwaguka hagati yuruhu rwa oxyde na umuyoboro w'icyuma.Amashanyarazi amaze gufungwa kugirango akonje, uruhu rwa oxyde ruzagwa, ibyo bikazana guhagarika umuyoboro wubushyuhe.Byongeye kandi, ingano nini ya oxyde izegeranya nyuma yo kugwa, ibyo bizagabanya kugabanuka cyangwa guhagarika umuvuduko wamazi kurukuta rwigitereko cyubushuhe no kwangirika kwingaruka zo gukonjesha mumazi, bizayobora neza. kurukuta rwa tube rushyushye cyangwa guturika.Muri rusange, kugirango hirindwe uruhu rwa oxyde kugwa, hafatwa ingamba nziza mugushushanya, gukora, gushiraho no gukora.By'umwihariko:
1.Mugihe cyogushushanya muri rusange, ubushyuhe bwurukuta rwo gupima ubushyuhe bwumuriro bugomba kugabanuka bishoboka, kandi ingingo zapimwe zigomba kugenzurwa buri gihe kugirango harebwe niba gupima ubushyuhe bwurukuta.Bitewe no gutandukana kwubushyuhe bwubushyuhe, ubushyuhe bwamazi yubushyuhe bugomba kugenzurwa ukurikije ubushyuhe bwemewe bwicyuma.Ubushyuhe bw'icyuma bugomba kugenzurwa cyane mugihe cyo gukora kugirango hatabaho ubushyuhe bukabije.
2.Guhitamo ubushyuhe bwo hejuru bwo gushyushya imiyoboro bigomba gutekerezwa ukurikije ubushyuhe bwo hejuru bwa okiside irwanya ubukana.Kumashanyarazi ya platine, superheater yibanze hamwe nubushyuhe bwa nyuma bwo gushyushya, SA213-TP347HFG na SUPER304H birashobora gukoreshwa nkibikoresho.
3.Kwiyongera kwinshi, kugabanuka kwurwanya no kwinjira no gusohoka muburyo bwa superheater murwego rwose bigomba gutegurwa muburyo bwiza bwo kugenzura no kugabanya gutandukana kwamazi.
4.Kumanika bigomba gutegurwa neza kugirango habeho intera ihagije, kandi umanika umwe agomba kwangwa.Kwimura ibikoresho bimanikwa mubihe bikonje bifatwa nka 40% ~ 60% yibyo bishyushye, kugirango ubushuhe bwa platine bushobora kwitwaza mubukonje kugirango byongere imbaraga zo kurwanya deformasiyo.
5.Wemeze kwaguka kubusa hejuru yubushyuhe bwa platine.Ahantu ubushuhe bwa platine bwanyuze murukuta, hagomba gukoreshwa kwaguka kwicyuma hamwe nuburyo bufatika.Muri icyo gihe, imiterere yinkokora itunganijwe neza yemerewe gusohoka hejuru yubushyuhe bwa platine kugirango yongere ubworoherane bwa platine kandi ikureho deformasiyo yatewe no kwaguka.
6.Mugihe cyo gukora, amazi ya desuperheating hamwe no guhuha soot bizakoreshwa bihamye bikurikije uburyo bwateganijwe bwo gutangira no guhagarika, guhindura imizigo nigipimo cyimihindagurikire yubushyuhe, kugirango bigabanye gutandukana nubushyuhe, kwirinda ubushyuhe bukabije n’imihindagurikire y’ubushyuhe butunguranye, kandi bishimangira kugenzura amazi n’amazi. ;Gukonjesha ku gahato birabujijwe rwose kubitetse bifite ibibazo byikigereranyo nyuma yo guhagarika.
7.Muburyo bwo gutangira, guhagarika no guhindura imitwaro, gerageza kubuza ihindagurika ryubushyuhe bwigihe hamwe nubushyuhe bwimihindagurikire yubushyuhe, kandi ugabanye gukuramo uruhu rwa oxyde.
8.Mugihe cyo kuyitunganya, hagomba gukoreshwa icyuma cyerekana uruhu rwa oxyde kugirango hamenyekane uruhu rwa okiside ya superheater na reheater, kandi ubuzima bwumurimo bwiyo miyoboro buzasuzumwa kandi imiyoboro ifite okiside ikabije isimburwe mugihe.
9.Shimangira igenzura ryubushyuhe hamwe numutwe, kandi urebe neza ko imbere yubushyuhe hasukuye kandi nta myanda.Uhereye ku mikoreshereze nyayo ikoreshwa cyane mu gutekesha ibitanda byogeye muri iki gihe, ikibazo cyacyo ntigikomeye cyane kuruta icy'amakara yatwitswe, nacyo kikaba ari akarusho gakomeye ko kuzenguruka mu mazi.
Hariho impamvu zibiri zingenzi zituma umunzani ugabanuka hejuru yubushyuhe bwo hejuru bwubushyuhe bwo hejuru bwikwirakwizwa ryamazi meza.Imwe ni uko igipimo kigera ku mubyimba runaka;Ibindi ni inshuro nyinshi, nini kandi nini yo hejuru yubushyuhe.Mubihe bisanzwe, dukwiye kugenzura mugihe cyateguwe kubikorwa byo guteka kandi tugahora dusuzuma niba hari akaga kihishe muri boiler.
