Abstract:

The principle, flow, feature, running of pneumatic delivery of dust collected from coke-making production as well as dust collected from coke-making production which is used for blast furnace pulverized coal injection were introduced, the key technical issue was studied. The production practice showed that long distance non-pollution delivery was realized in pneumatic delivery mode, material can be taken and discharged in many points, the process was automatically controlled. Dust also can be mixed quantitatively with pulverized anthracite injected into blast furnace, part of anthracite can be replaced, so that comprehensive utilization of non secondary pollution of dust collected from de-dusting was realized.
