Umbhobho weBoiler
Iityhubhu zebhoyila yenye yemibhobho engenamthungo.Iindlela zokuvelisa ziyafana netyhubhu engenamthungo, kodwa ineemfuno ezingqongqo zokwenza imibhobho yentsimbi.Ngokwenqanaba lobushushu, ityhubhu yebhoyila yahlulwe ibe yityhubhu yebhoyila ngokubanzi kunye netyhubhu yebhoyila yoxinzelelo oluphezulu.
Iindlela zokuvelisa:
① Ubushushu betyhubhu yebhoyila ngokubanzi bungaphantsi kwama-450 ℃, kusetyenziswa umbhobho oqengqelekayo oshushu okanye umbhobho otsalwa ngokubanda wenza umbhobho wentsimbi.
② ityhubhu yebhoyila enoxinzelelo oluphezulu isetyenziswa rhoqo kwiimeko zobushushu obuphezulu kunye nombhobho woxinzelelo oluphezulu, ifuthe legesi yobushushu obuphezulu kunye nomphunga wamanzi, i-oxidation kunye nokuhlwa.Umbhobho wensimbi onamandla amakhulu okuqhekeka, ukuchasana okuphezulu kwi-oxygen corrosion kwaye ube nokuzinza okuhle kwentlangano.
Iinjongo zebhobho yebhoyila:
① Iityhubhu zebhoyila ngokubanzi zisetyenziswa ikakhulu ukwenza iityhubhu eludongeni lwamanzi, iityhubhu emanzini abilayo kunye nombhobho oshushu kakhulu, iityhubhu zebhoyila ezishushu kakhulu, umbhobho omkhulu kunye omncinci kunye nezitena zearch.
② ityhubhu yebhoyila enoxinzelelo oluphezulu isetyenziswa ikakhulu ukwenza uxinzelelo oluphezulu kunye netyhubhu yoxinzelelo oluphezulu lwebhoyila, iityhubhu zokufudumeza kwakhona, indlela yomoya, owona mbhobho womphunga.
Udidi:
Iityhubhu zebhoyila ngokubanzi kunye netyhubhu yebhoyila yoxinzelelo oluphezulu ibonakaliswa ekusebenzeni kobushushu obuphezulu.Iityhubhu ze-boiler ngokubanzi, okanye iityhubhu zebhoyila zoxinzelelo oluphezulu ngokwendlela yokusetyenziswa kwazo zinokuhlulwa zibe ziindidi zemibhobho yentsimbi.
