| Abstract: | In this paper the improvement and optimization in blast-furnace PCI technology is des-cribed.The improvement in coal pulverizing system includes:eliminating the primary fan and putting the whole system in subatmospheric pressure,reducing or eliminating the cyclones andadopting mid-speeded grinder in place of ball mill.The improvement in injecting system includes:adopting "single tube-distributor" route,using widely fluidizing technique,adopting dense-phase transportation technique and developing the messuring technique of PC flow rate in each tube and its adjustment method etc |
