Calorific Value of Coke 2. Influence of the Packing Density of the Coal Batch

Laboratory research indicates that the gross calorific value of blast-furnace coke is greatest for batch with Ro = 0.913–0.942%, Vdaf = 30.9–31.0%, Cdaf = 83.8%, Hdaf = 5.01–5.02%, and $${\text{O}}_{d}^{{daf}}$$ = 8.42–8.45%. Increase in the packing density of coking batch of consistent quality from 800 to 1150 kg/m3 increases the gross calorific value of blast-furnace coke by 0.05–0.12 MJ/kg.
