分析了煤粉的输送性能，对安钢2000级高炉喷煤系统进行了部分改造并完善了煤量控制，从而解决了喷煤量上不去、波动大的问题。改造后，煤量波动控制在1.5％以下，满足了高炉对喷煤的要求。
分析瞭煤粉的輸送性能，對安鋼2000級高爐噴煤繫統進行瞭部分改造併完善瞭煤量控製，從而解決瞭噴煤量上不去、波動大的問題。改造後，煤量波動控製在1.5％以下，滿足瞭高爐對噴煤的要求。
분석료매분적수송성능，대안강2000급고로분매계통진행료부분개조병완선료매량공제，종이해결료분매량상불거、파동대적문제。개조후，매량파동공제재1.5％이하，만족료고로대분매적요구。
The pneumatic conveying properties of pulverized coal were analyzed .Part of the coal in-jection system and the fine coal quantity adjustment system were modified to solve the coal injection quantity is weak, the problem of large fluctuations.After modification, the coal quantity fluctuation control under 1.5%, meet the requirements of the coal injection in the blast furnace .
