Different sizes of test coke ovens are employed to simulate industrial oven carbonization conditions in evaluating coking properties of commercially available coal. The evaluation conclusions often demonstrate significant variability due to differences in oven size, heating profile and charge bulk density.
In this study, four American coal samples were carbonized in 480 kg, 350 kg, and 17 kg movable-wall test ovens. The results confirmed that the differences in coal evaluation conclusions were mainly due to oven size, heating profile, and charge bulk density. Combined with other available research conclusions, reasonable carbonization conditions are recommended for American commercial coking coal evaluation.
