Indlela yokuphucula ukufana kobushushu be iziko lokumelana ne-tubular?

Eyokuqala: Sebenzisa (iteknoloji entsha) isixhobo sokutsha:

Isitshisi esilawula ubushushu besantya esiphezulu sisetyenziselwa ukufaka endaweni yesitshisi esinesantya esisezantsi. I-high-speed burner ngokusisiseko kukutsha okupheleleyo kwepetroli kunye nomoya ovuthayo kwigumbi lokutsha, kunye negesi ephezulu yokushisa emva kokutshisa ifakwe ngesantya se-100-150m / s, ngaloo ndlela iphucula ukuhanjiswa kobushushu obuguquguqukayo. Ukukhuthaza ukujikeleza kwerhasi kwiziko ukufezekisa injongo yobushushu bomlilo obufanayo. Ukongezelela, ngokungena kumoya wesibini, ukushisa kwegesi yokutshisa i-outlet kuncitshiswe ukusondela kwiqondo lokushisa lokushisa kwe-workpiece, kunye nokushisa kwegesi ye-flue inokulungiswa ukuze kuphuculwe umgangatho wokufudumeza kunye nokugcina i-fuel. Isiphumo esibalulekileyo.

Ezimbini: Lawula uxinzelelo kwiziko:

Xa uxinzelelo kwisithando somlilo lubi, umzekelo, ukuba uxinzelelo kwisithando somlilo -10Pa, isantya sokufunxa i-2.9m / s sinokuveliswa. Ngeli xesha, umthamo omkhulu womoya obandayo ufunxelwa emlonyeni wesithando somlilo kunye nezinye iindawo ezingaqinanga, ezibangela ukuba i-flue gas ishiye isithando somlilo. Ukulahleka kwekhalori ukusuka ekuhambeni kwandisa. Xa uxinzelelo kwisithando somlilo lulungile, i-gas ye-flue ephezulu yokushisa iya kuphuma ngaphandle kwesithando somlilo, eya kubangela ukulahleka kobushushu begesi ye-flue.

Okwesithathu: Phucula inqanaba lolawulo oluzenzekelayo:

Iziphene ezibangelwa kukufudumeza okungafanelekanga zinokwahlulwa zibe:

1. Iziphene ezibangelwa utshintsho kwimo yekhemikhali yomgangatho wangaphandle we-blank ngenxa yempembelelo ye-medium, impembelelo ye-medium, impembelelo ye-medium, utshintsho lwemo yekhemikhali yoluhlu lwangaphandle lwe-blank. kubangelwa i-oxidation, i-decarburization, i-carbonization kunye ne-sulfidation, ukungena kobhedu, njl.

2. Iziphene ezibangelwa utshintsho olungaqhelekanga kwisakhiwo sombutho wangaphakathi, njengokushisa, ukushisa kunye nokungabikho kobushushu.

3. Ngenxa yokusabalalisa okungafaniyo kweqondo lokushisa ngaphakathi kwe-billet, ukugqithiswa kwangaphakathi okugqithisileyo (okufana nokushisa kweqondo lokushisa, ubunzima bezicubu) kuveliswa, kwaye i-billet cracks.
