Resumo

The pilot-scale coking test retort permits less time consuming investigations with limited quantities of coals in comparison to the semi-industrial scale coke oven. DMT collect coke qualities and carbonization behavior data from coal and coal blend carbonization tests, which done parallel in the pilot-scale coking test retort and semi- industrial coke oven as well as in industrial coking plants, since 15 years. The pilot- scale coking test retort was dedicated for the fast and economical test for the determination of the CRI and CSR of coking coals. The evaluation of this bulk of coal and coke data shows also a high transferability of other important values from the retort test to the industrial coke ovens. DMT will present the comparison between semi-industrial coke oven and the pilot-scale coking test retort in terms of CRI/CSR, mechanical strength and internal gas pressure.
