长焰煤配煤炼焦在平遥煤化的研究与应用

Research and Application of Long Flame Coal in Coal Blending for Coke Making in Pingyao Coal Chemical Industry

长焰煤具有高挥发分、低灰、低硫的特点,在配煤炼焦中适当引入可以降低配煤成本。本文通过40 kg小焦炉试验和大焦炉工业生产数据研究表明,在保证焦炭质量合格的情况下,优化配煤结构,加大长焰煤配比,可以大幅度降低配煤成本,实现效益的最大化。

Long flame coal has the characteristics of high volatile matter,low ash,and low sulfur.Proper introduction in coal blending and coking can reduce the cost of coal blending.This article shows through the 40kg small coke oven test and industrial production data research of large coke ovens that optimizing the coal blending structure and increasing the proportion of long flame coal can significantly reduce the coal blending cost and achieve maximum benefits while ensuring the quality of coke is qualified.
