Mechanism of Fine Coke Generation under Drum Test
The behavior of fine coke generation during the drum test was investigated considering the coke breakage mechanism.Change in fine generation rate,its Weibull analysis and size distribution of fines wereas examined.Coke fines after the drum test wereas divided into the following three classes:.(1) Under 0.5mm fines generated by compressive breakage of coke matrix.(2) 6 to 15mm fines generated by volume breakage induced by cracks and defects in coke lump.(3) 0.5 to 6mm fines influenced by both compressive breakage and volume breakage.Also,the amount of these fines wasere related to the coke properties.The aAmount of 0.5mm under fine and Brinell hardness,which represents the strength of the coke matrix,had good correlation.On the other hand,volume breakage was influenced by the volatile matter content and fluidity of raw coal.
