高炉喷吹煤粉工艺是目前冶炼普遍采用的一项节能降耗的技术手段,由于瞬时喷煤量的较大波动严重地影响了高炉炉况顺行和喷煤水平的提高。实验得出瞬时煤量的波动较大时,可以通过调节二次风流量、喷吹罐压、流化风量等影响参数来抑制其波动,三者之间直接和间接的相互关系,使高炉炉况顺行稳定而提高生产效益。
Blast furnace pulverized coal injection technology is currently widely used in smelting a means of energy saving, due to the instantaneous amount of coal sprayed larger fluctuations have seriously affected the smooth blast furnace conditions and improve the level of coal injection. The experimental results show that when the fluctuation of instantaneous coal amount is large, the fluctuation of secondary air flow, injection tank pressure and fluidized air flow can be restrained by the influencing parameters such as the direct and indirect relationship between the three so that the blast furnace Stable along the line and improve production efficiency.
