Coal carbonization for various kinds of coals has been carried out in a movable-wall test coke oven(0.2W×0.4H×0.45L) to investigate the variation of coking pressure when dried coal is charged in the coke oven. Also fluidity properties of single coals and coal blends have been determined in a Gieseler plastometer. Fluidity of single coal increases with increasing volatile matter content. Fluidity of coal blends is largely depended on that of single coal rather than volatile matter content of coal blends. CO₂ reactivity and coke strength index after reaction with CO₂(CSR) of coke produced from single and coal blends also have been evaluated. With increasing the amount of strong-coking coal, CSR of the coal blend increased but CO₂ reactivity of the coal blend decreased. Effects of coal rank and moisture content on coking pressure in a 30kg of test coke oven were determined. Coals(PH, DP) with high fluidity exhibit high coking pressure but despite of low fluidity a coal(NP) represents the largest coking pressure among the coals tested. Bulk density of the dried coal(5-6 wt%) is 13-20% higher than that of the wet coal(7-9 wt%). Coking pressure of the dried strong-coking coal is approximately two times as high as that of the wet coal and internal gas pressure in the dried coal charge center is also much higher than that in the wet coal charge center.
