高炉制粉系统是为高炉磨制合格的喷吹煤粉。在原煤磨制成煤粉过程中,需要通过干燥炉提供的干燥气,将其含水量由10%降低至2%以下。为保证管道畅通、输气正常,高炉制粉系统中还需安装煤气排水器。其可以连续不断地排除煤气管道中析出的含腐蚀性机械水、冷凝水和污物,对干燥炉的正常燃烧起着至关重要的作用。宝钢集团有限公司四高炉二喷作业区(以下简称“四高炉”)制粉 Blast furnace milling system for blast furnace pulverized coal injection qualified. In the process of pulverizing raw coal into pulverized coal, it is necessary to reduce the water content from 10% to less than 2% through the drying gas provided by the drying furnace. In order to ensure the smooth flow of the pipeline and the normal gas transmission, a gas drainage device needs to be installed in the blast furnace pulping system. It can continuously exclude the gas pipeline containing corrosive mechanical water, condensed water and dirt, the normal combustion of the drying furnace plays a vital role.
