Experimental Study on MnO2 Acting as Pulverized Coal Injection into Blast Furnace

摘要

Catalyst of pulverized coal is one of important measures to improve the combustion process of pulverized coal in the blast furnace injection conditions.This paper mainly studies the effect of anthracite and bituminous coal adding different proportions of MnO2 on its ignition temperature,explosiveness and heat productivity.Also compared and analyzed the different influence of the three test samples on coal catalysis and meanwhile to fine out the best adding ratio of catalystMnO2 to different test samples.
