| Abstract: | The exergy analysis of the waste heat boiler in fluid catalytic cracking unit was carried out by the exergy analysis method. The exergy efficiency expression of the waste heat boiler system in the operation was analyzed; And practical calculation and analysis were carried out by this method, application status of effective energy from the waste heat boiler was gained, some factors to affect the exergy efficiency of the waste heat boiler were analyzed, it＇s determined that the key link of the exergy loss was smoke exhaust and heat transfer. After transformation of the waste heat boiler with optimal scheme, the exergy efficiency of the waste heat boiler would be increased by 10.4% if the exhaust ~as temnerature droos to 150 ℃. |
