Umbhobho we-boiler luhlobo lwetyhubhu engenamthungo.Indlela yokuvelisa iyafana nombhobho ongenamthungo, kodwa kukho iimfuno ezingqongqo kuhlobo lwentsimbi esetyenziselwa ukwenza umbhobho wensimbi.Ngokutsho ukusetyenziswa lobushushu yahlulwe zibe ziindidi ezimbini kwibhoyila ityhubhu jikelele kunye noxinzelelo oluphezulu kwibhoyila ityhubhu.

Ipropathi yomatshini wetyhubhu yebhoyili isalathiso esibalulekileyo sokuqinisekisa ukusebenza kokugqibela kwentsimbi.Kuxhomekeke kwimichiza yentsimbi kunye nenkqubo yonyango lokushisa.Kwinqanaba lombhobho wensimbi, ngokweemfuno ezahlukeneyo zokusetyenziswa, kuchazwe iimpawu zokuqina (amandla okuqina, amandla emveliso okanye indawo yesivuno, ukunyusa) kunye nobunzima, izikhombisi zokuqina, kunye neemfuno zomsebenzisi zokusebenza okuphezulu kunye nokuphantsi kobushushu.

① Ubushushu betyhubhu yebhoyila ngokubanzi bungaphantsi kwe-350℃, umbhobho wasekhaya wenziwa ikakhulu kwiNombolo ye-10, akukho.I-20 yentsimbi yekhabhoni eshushu iqengqeleke umbhobho okanye umbhobho ozotyiweyo obandayo.

(2) Iityhubhu zebhoyili ezinoxinzelelo oluphezulu zihlala zisetyenziswa phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.Ngaphantsi kwesenzo segesi ephezulu yokushisa kunye nomphunga wamanzi, i-oxidation kunye ne-corrosion iya kwenzeka.Umbhobho wensimbi ufuneka ukuba ube namandla ahlala ixesha elide, ukuxhatshazwa kwe-corrosion ephezulu ye-oxidation kunye nokuzinza okulungileyo kwe-microstructure.
