Abstract

The process of high wind and oxygen volume (PHWO), at 'time' aspect, will lead to mass flow increasing and unfavourable and jam-packed gas channels (JGC). Furthermore, there is the most jam-packed state in dripping zone, next in cohesive zone, then in lump zone. Accordingly, a new index is introduced in this article to estimate the crowded state of gas channels. At 'space' aspect, owing to the raceway enlarging and the inactive coke column shrinking, the effective amount of gas channels trends upward, as can mitigate jam-packed state of gas channels to promote the smooth running. Since original gas distribution takes on central gas flow is developed and the edge gas flow is restrained, it is necessary to adjust the charging mode to match.
