鼓风湿度对炼铁焦比的影响,国内外早有研究。1904年美国宾夕法尼亚伊若毕尔工厂第一次采用空气冷凝法进行脱湿鼓风,水分从10～12克/米~3降到3～3.5克/米~3,高炉增产25％,焦比下降20％。50年代,我国高炉广泛采用加湿鼓风,促进了高风温的使用,有利于炉况顺行。但水分分解要消耗热量,因此,1955年全国高炉会议规定蒸汽鼓 Blower humidity on the impact of iron-making coke, both at home and abroad have long been studied. For the first time in 1904, the factory in Ilobil, Pennsylvania, USA, dehumidified by air condensation method. The water content dropped from 10 to 12 g / m 3 to 3 to 3.5 g / m 3. The blast furnace output increased 25% Down 20%. In the 1950s, extensive use of humidifying blast furnace blast furnace, and promote the use of high wind temperatures, is conducive to furnace conditions go. However, the decomposition of water to consume calories, therefore, the 1955 National Blast Furnace provides steam drums
