Investigation of Bonding Pattern of Coal Particles and Factors for Determination of Coke Properties during Carbonization

Abstract

The coking mechanism is considered as a process that the pulverized coal is changed into a lump of porous carbon structure after it is softened and melted with thermally decomposition by heating. From this point of view, the following items are investigated.
(1) A bonding pattern for lumping the pulverized coal and a mechanism for the distribution of coke porosity across the oven width.
(2) Analysis of affecting factors of an inherent strength and grafitization which are important for the evaluation of coke qualities.
