Conveying Property of Injection Pulverized Coal into Blast Furnace

Abstract:

The dynamic characteristic parameter of conveying property of pulverized coal is described with the conveying mass of pulverized coal in unit time. The conveying process of pulverized coal is studied by means of the pulverized coal’s conveying property testing equipment developed by ourselves. Results show that the conveying property of bituminous coal is better than anthracitic coal. If the improvement of conveying property of pulverized coal is considered purely, the size of pulverized coal can properly be reduced and the proportion of anthracitic coal can properly be decreased. The water content of pulverized coal can be controlled from 1% to 2%.
