    • PURPOSE:To restrict any reaction between the fine powder coal and oxygen and prevent toxication of carbon monoxide or spontaneous combustion by a method wherein inactive gas is fed into the layer of fine powder coal stored in the closed tank and the air in the layer is replaced with the inactive gas. CONSTITUTION:After the fine powder coal 3 is fed into the tank 1, an opening/ closing valve 6 is opened. Then, the inactive gas is fed into the layer of fine powder coal 3 from the blowing port nozzle 5 arranged an appropriate location of the lower part of tank 1, namely at a position lower than X/L=0.6, thereby the air in the tank 1 is discharged out of the tank 1 through the fine powder coal supplying pipe 8 and the air in the layer of fine powder coal 3 is replaced with the noble gas. Then, L is depth of the layer of the fine powder coal 3 and X is a distance ranging from the upper surface of the layer to the nozzle 5.
    • 目的:为了限制细粉煤与氧之间的任何反应,并通过将惰性气体进入储存在密闭罐中的细粉煤层中并且更换层中的空气的方法来防止一氧化碳或自燃的燃烧 与惰性气体。 构成:将细粉煤3送入罐1后,打开/关闭阀6。 然后,将惰性气体从设置在罐1的下部的适当位置(即在低于X / L = 0.6的位置)的吹出口喷嘴5供给到细粉煤层3中,从而将 罐1通过细粉煤供给管8排出罐1,细粉煤层3中的空气被惰性气体代替。 然后,L是细粉煤3的层的深度,X是从层的上表面到喷嘴5的距离。
