焦炭是高炉炼铁的重要燃料和还原剂,也是整个高炉料柱的支撑剂和疏松剂。减少焦炭中的水分含量有利于降低高炉的综合焦比,减少焦炭的水分波动有利于提高吨铁的热平衡。焦炭有露天敞开式储存和封闭式储存两种方式。在敞开式储存条件下,焦炭容易受到雨水的浸泡,水分增加;在封闭式储存条件下,焦炭不会被雨水浸泡,但工程投资高。通过研究正常焦炭、蜂窝焦和粉焦占不同比例,且在不同初始含水率的条件下,焦炭水分增加与浸泡时间的关系,得出储存方式对不同状态焦炭含水率变化的影响程度,为焦炭储存方式的选择提供依据。
Coke is an important fuel and reductant for blast furnace ironmaking and is also a proppant and bulking agent for the entire blast furnace column. Reduce the moisture content of coke is conducive to reducing the overall coke ratio of the blast furnace to reduce water fluctuations in coke is conducive to improving the thermal balance of iron. Coke open-air storage and closed storage in two ways. Under open storage conditions, coke is susceptible to soaking in the rainwater and increasing moisture; coke is not soaked in rainwater under closed storage conditions, but with high engineering investment. By studying the relationship between normal coke, honeycomb coke and powder coke in different proportions, and under the different initial moisture content, the relationship between coke moisture increase and immersion time, the influence of storage mode on the moisture content of coke Provide a basis for the choice of storage methods.
