根据相似原理，通过物理模型研究了格子体堵塞部位、堵塞率同格子体内气流分布之间的关系。研究表明：中部或底部发生堵塞时，格子体内气流分布的变化规律是相同的，即开始是随着堵塞率的增加，气流分布趋于均匀，堵塞到一定程度后。气流分布均匀性随着堵塞率的增大而变差；中部堵塞气流分布变化趋势比底部塔塞时要快一些；堵塞后，蓄热室的阻力损失变大，但是变化趋势缓慢。传热分析表明：轻微的堵塞会改善格子体内气流分布，提高格子砖利用率．
Based on the similarity principle, the relationship between the clogging rate of the grid body and the airflow distribution in the grid body was studied through a physical model. Studies have shown that: When the middle or bottom clogging occurs, the distribution of air distribution in the grid is the same, that is, with the increase of the clogging rate, the distribution of air flow tends to be even and the clogging is to some extent. The uniformity of airflow distribution becomes worse as the jam rate increases; the distribution trend of air flow in the middle jam is faster than that of the bottom jam; after the jam, the resistance loss of the regenerator increases, but the change trend is slow. The heat transfer analysis shows that slight clogging improves the airflow distribution in the lattice and improves the utilization of the lattice bricks.
