摘　　要：为了探讨单种煤性质对焦炭热性能之间的联系,采用40kg小焦炉实验研究了11种单种煤变质程度、灰分、硫分以及黏结指数对焦炭反应性和反应后焦炭热强度的影响。实验结果表明:单种煤的变质程度对焦炭热性能存在显著影响。同时,单种煤的灰分、硫分以及黏结指数都是影响焦炭热性能的主要因素。In order to investigate the relationship between the properties of single coal and the thermal properties of coke.This paper researches the effects of the coal metamorphism,ash content,sulfur fraction and the bond index of 11 single coals on the reactivity and thermal strength of coke after reaction in the 40 kg small coke oven.The experimental results show that the coal metamorphism of single coal has a significant influence to the thermal performance.Moreover,the ash content,sulfur fraction and the bond index of single coal are the main element to the thermal performance.
