Energy Balance Analysis of No.1 Sinter Machine at Baosteel

Abstract:

On the basis of the thermal balance, the exergy balance of No.1 sinter machine at Baosteel was analyzed. The exergy efficiency is lower than the thermal efficiency. The main exergy loss are focused on physical water evaporation exergy of sintering mixture, chemical incomplete combustion exergy, irreversible exergy loss of ignition process, irreversible exergy loss of sintering process. The measures of saving exergy of sinter machine are proposed. The exergy efficiency can be increased by increasing the sintering material layer thickness and the temperature of the mixture, reducing the moisture of mixture, choosing the reasonable fuel particle size and particle size distribution, controlling minimum air-fuel ratio, improving material layer permeability and using hot air sintering.
