不同粒度气煤和瘦煤参与配煤炼焦比较

Comparison of Different Particle Size Gas Coal and Lean Coal in Coal Blending Coking

既要比较气煤、瘦煤的煤质特征,也要对比胶质层测试后焦块形貌,还要对比焦炭光学组织,结果显示,气煤成焦惰性结构高,在配煤炼焦中,起到瘦化作用,但两者拥有不同的结焦特性,气煤反应活性较高。不管是气煤,还是瘦煤,既要对比自黏结强度,也要对比成焦显微结构特征,结果显示,在配煤炼焦中,气煤的粒度应控制在合理范围,不应过大,也不应过小,助力提升焦炭质量;在配煤炼焦中,瘦煤应适度细粉碎,助力提升焦炭质量。本篇文章主要对比两者之间的各种差异,使其共同发挥配煤炼焦的作用,从而为该领域提供参考意见。

It is necessary to compare the coal quality characteristics of gas coal and lean coal,the morphology of coke block after colloidal layer test,and the optical structure of coke.The results show that gas coal has high coking inert structure and plays a role in coal blending and coking,but they have different coking characteristics and high gas coal reaction activity.The results show that in coal blending and coking,the particle size of gas coal should be controlled within a reasonable range,not too large or too small,so as to help improve the quality of coke;In coal blending and coking,lean coal should be finely crushed to help improve coke quality.This article mainly compares the differences between the two,so as to make them play the role of coal blending and coking and provide reference for this field.
