Gusaba
Ahanini ikoreshwa kumuvuduko mwinshi hamwe nubushyuhe bwo hejuru bwa boiler (Umuyoboro wa superheater, umuyoboro wa reheater, umuyoboro woguhumeka, umuyoboro wingenzi wamazi yo hejuru hamwe na ultra high high boiler). Bitewe nubushyuhe bwo hejuru bwa gazi ya gazi hamwe numwuka wamazi, umuyoboro uzahinduka okiside kandi ukangirika. Birasabwa ko umuyoboro wibyuma ufite igihe kirekire, ukarwanya okiside na ruswa, hamwe nuburyo bwiza bwimiterere.

Uburebure:
Uburebure busanzwe bw'imiyoboro y'ibyuma ni 4 000 mm ~ 12 000 mm. Nyuma yo kugisha inama hagati yuwabitanze nuwaguze, akuzuza amasezerano, irashobora gutangwa imiyoboro yicyuma ifite uburebure burenga mm 12 000 cyangwa ngufi ya mm 000 ariko ntibiri munsi ya mm 3 000; uburebure bugufi Umubare wibyuma bitarenze mm 4000 ariko ntibiri munsi ya 3000 mm ntibishobora kurenga 5% byumubare wibyuma byatanzwe
Uburemere bwo gutanga ：
Iyo umuyoboro wibyuma utanzwe ukurikije diameter yinyuma yinyuma nuburebure bwurukuta rwizina cyangwa diameter yimbere yimbere nubunini bwurukuta rwizina, umuyoboro wibyuma utangwa ukurikije uburemere nyabwo. Irashobora kandi gutangwa ukurikije uburemere bwa theoretical.
Iyo umuyoboro wibyuma utanzwe ukurikije diameter yinyuma nubunini bwurukuta ntarengwa, umuyoboro wibyuma utangwa ukurikije uburemere nyabwo; gutanga no gusaba amashyaka araganira. Kandi bigaragarira mu masezerano. Umuyoboro wibyuma urashobora kandi gutangwa ukurikije uburemere bwa theoretical.
Kwihanganira ibiro ：
Ukurikije ibisabwa nuwaguze, nyuma yo kugisha inama hagati yuwabitanze nuwaguze, no mumasezerano, gutandukana hagati yuburemere nyabwo nuburemere bwamahame bwumuyoboro wibyuma bitanga bigomba kuba byujuje ibi bikurikira:
a) Umuyoboro umwe w'icyuma: ± 10%;
b) Buri cyiciro cyimiyoboro yicyuma gifite ubunini buke bwa 10 t: ± 7.5%.
Ibisabwa
Ikizamini cya Hydraustatic:
Umuyoboro wibyuma ugomba kugeragezwa mumazi umwe umwe. Umuvuduko ntarengwa wikizamini ni 20 MPa. Mugihe cyumuvuduko wikizamini, igihe cyo guhagarara ntigomba kuba munsi ya 10 s, kandi umuyoboro wibyuma ntugomba gutemba.
Umukoresha amaze kubyemera, ikizamini cya hydraulic gishobora gusimburwa na eddy igeragezwa cyangwa igeragezwa rya magnetiki flux.
Ikizamini kidahwitse ：
Imiyoboro isaba ubugenzuzi bwinshi igomba kugenzurwa na ultrasonique imwe imwe. Nyuma yumushyikirano usaba uruhushya rwababuranyi kandi bisobanuwe mumasezerano, ibindi bizamini bidasenya birashobora kongerwaho.
Ikizamini cya Flattening ：
Imiyoboro ifite diameter yo hanze irenga mm 22 igomba gukorerwa ikizamini. Nta gutandukanya kugaragara, ibibara byera, cyangwa umwanda bigomba kubaho mugihe cyubushakashatsi bwose.
Ikizamini cyo gutwika:
Ukurikije ibisabwa n’umuguzi kandi byavuzwe mu masezerano, umuyoboro wibyuma ufite diameter yo hanze ≤76mm hamwe nuburebure bwurukuta ≤8mm birashobora gukorwa ikizamini cyo gutwika. Ubushakashatsi bwakorewe ku bushyuhe bwicyumba hamwe na taper ya 60 °. Nyuma yo gucana, igipimo cyaka cya diameter yo hanze kigomba kuba cyujuje ibisabwa kumeza ikurikira, kandi ibikoresho byikizamini ntibigomba kwerekana ibice cyangwa ibice.
