Mubvunzo: Dambudziko rekukuvadza kunzvimbo yekupisa pamagumo ejenareta remhepo rinokonzerwa sei?

A: Muswe wemuswe wejenareta uchange uine matambudziko akasiyana-siyana mushure mekushandiswa kwenguva yakareba, iyo inonyanya kuoneka kukuvara.Zvikonzero zvekurasikirwa kwekupisa kwepamusoro pamuswe wemuswe zvinoongororwa zvakadzama pasi apa.

Madota uye slag inopinda muflue kumagumo ine imwe kuoma nekuda kwekuderera kwayo.Kana ichinge yaburitswa pamwe chete neyekutanga kupisa pamusoro peiyo flue gasi, inokonzeresa kukanganisa kumadziro epombi.Kunyanya kune yekupisa kupisa, tembiricha yeflue gasi painopinza yadzika kusvika 450 ° C, madota zvidimbu zvakaoma, uye diki-dhayamita yakatetepa-yakavezwa kabhoni simbi pombi inoshandiswa, iyo inogona kunge iri. kukuvadzwa.

Panguva imwecheteyo, kukuvadzwa zvakare chimwe chezvikonzero nei kupisa kunopisa kunotsemura chikamu chepamusoro cheiyo steam jenareta ina-tube yekupwanya matambudziko.
Kuenzaniswa nekuyerera kwemudhuri wepombi, gasi reflue rine hard particle ash richakonzera kukanganisa kumadziro epombi, iyo inonzi erosion corrosion, inozivikanwawo sekukurwa.
Kune marudzi maviri ekutanga erosive kupfeka uye kukanganisa kukanganisa.Iyo microscopic morphology yemasimbi maviri ekudzivirira haina kufanana.
Kukuvadzwa kwekukukurwa kwevhu ndekwekuti kona yekukanganisa kweguruva pamadziro epombi inoenderana idiki, kunyangwe iri padyo nekuenderana.Madota zvidimbu akaparadzaniswa perpendicular pamusoro pemvura pombi rusvingo, achivaita akanyudzwa mukati akabatwa pombi rusvingo, uye chikamu simba pamharadzano dzemadota particles uye pombi rusvingo pamusoro inoita madota zvimedu kukunguruka pamwe pombi rusvingo pamusoro.chubhu madziro.Basa rekucheka chiso.Kana rusvingo rwepombi rusingagoni kumira chiito chekucheka chesimba rinoguma, pachava nesimbi yesimbi yakavharwa kubva mumuviri wepombi uye yakaderedzwa.Pasi penguva refu yakadzokororwa yekucheka chiito chehuwandu hwemadota, pamusoro pemadziro epombi ichakuvadzwa.
Impact kukuvadzwa kunoreva kuti kona inokonzeresa pakati pehuruva zvidimbu uye pamusoro pemadziro epombi yakakura, kana padyo neakatwasuka, uye pamusoro pemudhuri wepombi inoiswa pakumhanya kunoenderana nekufamba, kuitira kuti madziro epombi epamusoro aite diki. kuchinja kwechimiro kana micro cracks.Pasi penguva refu yakadzokororwa kukanganisa kwenhamba huru yeguruva, iyo flat denatured layer yakasvuuka zvishoma nezvishoma uye yakakuvadzwa.
