Optimization and Innovation of Pulverized Coal Transferring of Coal Injection System for Blast Furnace
This paper introduces granular coal system of 2×1880 m3 blast furnace in Laiwu Section Steel Iron-making Plant.In view of the problems existing in the original pulverized coal transferring process system,injection of granular coal system was optimized and innovated during the overhaul of blast furnace.The measures such as replacing worn pipes and thickening main pipes,increasing shut-off valves and setting reserved openings were adopted to ensure the fluidity of pulverized coal,and injection by six groups of injection tanks into Phase Ⅰ and Phase Ⅱ granular coal collecting systems was achieved,which created conditions for disassembling and replacing the rotary feeder in overhaul.
