Abstract

The magnitude of coke layer collapse is mainly dominated by charging mode. The state of coke stacking after the collapse is also influenced by gas flow and descending velocity distribution. The changes in inclination angle of the coke layer and coke movement accompanied by the collapse have been investigated. The scale collapse depends on the stability of inclined coke layer. On the base of these findings, a mathematical model for quantitative evaluation of coke layer collapse is developed by introducing the theory of soil mechanics.
