摘要

在热重分析仪上考察了内在矿物质和三种无机组分（CaO、Fe

和Al

）对不同还原程度煤显微组分半焦燃烧反应性的影响。结果表明，弱还原性煤显微组分半焦的燃烧反应性高于还原性煤显微组分半焦；内在矿物质降低了镜质组半焦的起燃温度，但对惰质组半焦燃烧有明显抑制作用；三种外加矿物质对还原性煤显微组分半焦燃烧均有抑制作用，抑制顺序为Al

CaO

，而CaO对弱还原性煤显微组分半焦燃烧有一定催化作用，并且Al

和Fe

对弱还原性煤显微组分半焦燃烧抑制作用也低于对还原性煤显微组分半焦燃烧的抑制作用。

Abstract

The effects of intrinsic minerals and three inorganic components (CaO

and Al

) on the semi-coke combustion reactivity of maceral with different reducibility were investigated on a thermogravimetric analyzer. The results indicated that the combustion reactivity of maceral chars from the weakly reductive coal is better than that from the reductive coal. The inherent mineral matter of vitrinite reduces the ignition temperature of vitrinite chars

while the inherent mineral matter of inertinite shows obvious inhibition effect on their chars combustion reaction. Three added mineral matter inhibit the combustion reaction of maceral chars from the reductive coal

and th

e relative inhibiton sequence could be described as follows: Al

CaO

while CaO has a little catalytic effect on the combustion reaction of maceral chars from the weakly reductive coal

and the inhibition effect of Al

and Fe

on the combustion reaction of maceral chars from the weakly reductive coals is lower than that on the combustion reaction of maceral chars from the reductive coal.
