摘要

用氢氟酸（ＨＦ）酸洗法制取脱灰煤，通过比较四种原煤（青山煤、合山煤、耒阳煤、金竹山煤）及其脱灰煤的热天平分析所得燃烧分布曲线的特征参数（综合着火指数Ｍ、综合燃烬指数Ｎ，外推起始温度Ｔ１，燃烬温度Ｔ２），并对在几种脱灰煤样中以机械混合或溶液浸泡方式添加了１１种不同种类和形态的矿物质，如ＳＩＯ２、ＣａＣＯ３、ＭｇＯ、Ｎａ２ＣＯ３、Ｋ２ＣＱ３、Ａｌ２Ｏ３、ＴｉＯ２、Ｆｅ２Ｏ３、ＦｅＳ２、硫酸铁铵、硫酸亚铁矮及所得添加矿物质煤样的不同燃烧特性进行研究，获得了矿物质影响煤燃烧特性的一般规律。

Abstract

Presented in this paper is a basic rule of the effect of minal mattsrs on coal combustion Propeties.This rule is obtained through a comparative study on the results of thermogravimetric analysis of four different coals and their deashed samplesand a study on the effect of added mineral materials

such as SiO2

CaCO3

MgO

NaZCO3

KZCO3

A12O3

TiO2

FeZO3

FeS etc

on combustion properties.
