Identify and correct coke drum foundation bolt failures

Research on coke making seeks to take advantage of insights that may help to reduce the proportion of prime coking coals utilised in coke blends and to expand the range of coals that could be used in these operations Sasaki et al 1998 Shifting the coke blend composition toward weakly coking coals is therefore commercially attractive However the role of the coke as a permeable medium is crucial in economic blast furnace operation The degradation of the coke varies with the position in the blast furnace but in all cases involves the combination of reaction with CO 2 H 2 0 or 0 2 and the abrasion of coke lumps against each other and other components of the burden
