As one of the methods for reducing the blast furnace coke rate, there is the technique of injection auxiliary fuels from the tuyers.<BR>Operating problems have been encountered when injecting coal as an auxiliary blast furnace fuel. These must be overcome before coal injection will receive widespred application.<BR>It is possible by such a simple measure as imprving the fuel oil injection equipment somewhat to obtain a slurry injection of 30wt% coal concentration; but at such a high concentration as 50wt%, the burner is liable to be clogged. It is thus necessary to contrive the injection equipment in such a way as to make the injection volumes even for all the tuyeres. By completing such an equipmene, we have been injected slurry of 50wt% coal concentration with satisfactory results.
