Technical evaluation of stable and low consumption system of power pipe network for coal injection system of 5 100 m³ blast furnace

As an important auxiliary system of blast furnace, the injection system injects pulverized coal for blast furnace continuously 24 hours a day. If the fault occurs in the injection system, causing coal stoppage, affecting the blast furnace condition, reducing air, destroying the long-term stable production state of the blast furnace, ensuring the stability of the injection system, in the innovation and optimization of the backup system, the influence of the failure of the injection system on the blast furnace can be minimized to ensure the continuity, stability and accuracy of the pulverized coal transportation in the injection system and the smooth operation of the blast furnace.
