Experiment and numerical simulation of sinter cooling in annular cooler

Abstract

Abstract Based on the empirical constant value of the thermal physical parameters of sinter, this paper combines experimental measurement and finite element simulation to study the equivalent thermal conductivity of sinter and establish a heat transfer model suitable for the cooling process of sinter. The influence of the empirical value and the change value on the cooling process is analyzed by analyzing the thermal property parameters of the sinter. The effects of sinter size and inlet air temperature on the cooling process are investigated by using varying thermal physical parameters. The results show that the smaller the particle size is, the higher the inlet air temperature is, and the higher the waste heat utilization rate of the outlet heat exhaust gas is.
