The studies of the behaviors of unburned pulverized coal in Blast furnace

摘要

The behaviors of unburned pulverized coal into BF had been investigated by experiments. It is found that the unburned pulverized coal mainly retains in area where the gas-flow is slower, it is accumulated in layer of ore at lump zone, in which it reacts with ore intensely at high temerature, so much of it can be used up in BF.
