贮仓式制粉系统磨煤机出口干燥剂的温度的选择一般是按表1选取的。选择的主要依据是防止制粉系统中水汽的结露,以及防止系统中煤粉的爆燃。在实际应用中还要考虑到磨煤设备及粉斗所能允许的最高温度。按表1,在燃用贫煤、无烟煤时,由于燃料的易爆、易燃性较差,因此常选取较高的磨 Silo storage system Pulverizer outlet desiccant temperature is generally selected according to Table 1. The main basis for selection is to prevent condensation of water vapor in the milling system and to prevent deflagration of pulverized coal in the system. In practical applications, we must also take into account the highest temperature that coal grinding equipment and powder hopper can allow. According to Table 1, when using lean coal and anthracite coal, the higher mill is often chosen because of the explosiveness of the fuel and the low flammability.
