Numerical simulation and parameters analysis on the gas-solid heat transfer process of high temperature sinter

Based on carefully analyzing the heat transfer mechanism of the cooling process of high temperature sinter, a one-dimensional unsteady mathematical model was established for the gas-solid heat transfer process of high temperature sinter according to energy conservation. The mathematical model was verified to be correct and reliable by real data. Lastly, the model was used to investigate the effects of main operation parameters such as the velocity of cooling air and the moving speed of the trolley on the cooling process of the annular cooler, and some proposals were put forward for operations of the annular cooler.
