Investigation on Improving Combustion Properties of Blast Furnace Pulverized Coal Injection

To improve the combustion properties of blast furnace pulverized anthracite injection,a series of technical measures are tested in laboratory,which include add soft coal and combustion-supporting substance into anthracite,oxygen-enriched blast,enhance wind temperature etc.The results show every measure can improve the combustion properties,the effect of oxygen-enriched blast is especially notable.Injecting blended pulverized coal combined with oxygen-enriched blast and enhancing wind temperature can notably improve the combustion properties of blast furnace pulverized anthracite injection.
