Abstract: The thermal balance of No.4 BF and No. 1 BF stove in Baosteel was calculated. On the basis of the re-
sults, the exergy balance was analyzed. The results show that the exergy efficiency is lower than the thermal effi-
ciency. The exergy efficiency of No. 1 BF stove is 6.54% less than No. 4 BF stove. The main loss of exergy is fo-
cused on the burning irreversible process,the waste gas discharging process,the heat exchanging process and the un-
completed burning process. The measures of saving exergy of hot blast stove are proposed. The exergy can be saved
by using reasonable air excess ratio,burning with oxygen-enriched air,reducing the temperature of waste gas,impro-
ving the temperature of cold air and raising the level of heat recovery device.
Key words: hot blast stove; thermal balance;exergy balance;exergy efficiency
