1.绪言 近来高炉脱湿鼓风已经成为降低高炉燃料比的措施之一。高炉需要用大量的风(1100—1200标米~3/吨铁)大气所含湿分随着昼夜与季节而变化。鼓风湿分从风口吹入炉内时,在风口前2200℃的高温区分解。这是个吸热反应,消耗了该区域的热量,相应地降低了风口前的温度。 1. INTRODUCTION Recently blast furnace dehumidification blasting has become one of the measures to reduce the blast furnace fuel ratio. The blast requires a large amount of wind (1100-1200 m 3 / t of iron) and the moisture content of the atmosphere varies with the day and night and the seasons. Blowing wet air blowing into the furnace from the tuyere, in the tuyere 2200 ℃ high temperature decomposition. This is an endothermic reaction that consumes heat in the area and correspondingly reduces the temperature in front of the tuyere.
