高炉喷吹济阳气煤的可行性研究

 对济阳不同煤层气煤及济阳气煤精煤的基础特性进行了系统研究，并与济钢常用的无烟煤和烟煤进行对比，探讨高炉喷吹气煤部分或完全替代其他煤种的可行性。通过对济阳气煤及对比煤种的工业分析、元素分析、灰成分分析、碱金属分析、可磨性、流动性、着火点、爆炸性、灰熔融特性、发热值、 燃烧性和反应性等的测定及深入分析，结合济钢1750m3高炉配入26%(质量分数，下同)气煤精煤进行喷吹的工业试验情况， 说明济阳气煤是一种非常理想的高炉喷吹燃料，并提出了高炉喷吹气煤要注意的问题。

Feasibility for Injecting Gas Coal From Jiyang Into Blast Furnace

In order to investigate the feasibility for injecting gas coal powder into blast furnace, the basic characteristics of gas coal in different coal bed and clean gas coal were investigated systematically. Also, the research results were compared with common anthracite and bituminous coal in the blast furnace of JIGANG. By the analysis of proximate analysis, ultimate analysis, ash analysis, alkalis metal analysis, grindability index, flowability index, igniting point, explosivity, ash fusion temperature, calorific value, combustibility and reactivity, combining with industrial test for injecting 26% clean gas coal at 1750m3 blast furnace in JIGANG, it is proposed that the gas coal from Jiyang is an ideal solid fuel for injection in blast furnace. Meanwhile, some issues are proposed for guiding the injection of gas coal powder in blast furnace.
