A pulverized coal injection system of Kawasaki`s own design and technology was first installed at No. 5 blast furnace of Chiba Works and started operation in October 1984. To reduce the consumption of costly coking coal and prolong the life of older coke ovens, PCI systems have also been introduced at Mizushima Nos. 3, 4 and Chiba No. 6 blast furnaces. The pulverized coal injection system and operational results at Mizushima No. 3 blast furnace, which is the most modern system in Kawasaki Steel Corporation and started its operation in October 1992, is described in this paper. The subjects discussed in this paper are as follows: (1) Introduction of modernized pulverized coal injection system for Mizushima No. 3 blast furnace, with features (2) Rating up operation of No. 3 PCI; (3) BF operation with a high coal injection rate; and (4) Improved points of equipment, such as a controllability of the PC injection rate.
