Abstract：The uniformity of airflow distribution is a key criterion of volume utilization ratio in top combustion hot stove checker chamber，which directly influences the heat storage capacity and hot blast temperature. The momentum and energy equations of a top combustion hot stove were solved by the numerical simulation with the standard k- ε model, and porous medium model，and the influence of checker chamber structure on the airflow distribution was also researched. The results showed that the airflow distribution in the traditional checker chamber with flat roof presented the tendency of higher edge speed and lower center speed，when changing the structure of the checker chamber to the convex top with higher around and lower center，the flow distribution improved significantly.
