摘要

煤质特性的全面分析是煤种清洁高效利用的前提，选取3种高氯高碱沙尔湖煤(A、B、C)和3种准东高碱煤(准东、宜化、红沙泉)，系统分析6种煤样的基础特性和热重特性．结果表明：沙尔湖煤灰中Na_2O含量(约4.00%)显著低于准东煤(8.98%)、宜化煤(6.47%)和红沙泉煤(9.23%)，但其Cl含量(0.262%～0.491%)远高于其他煤样(0.044%～0.084%)，其中沙尔湖A中Cl含量最高(0.491%)．沙尔湖煤可磨性指数(129～150)较高，但热稳定性(TS+6=47.0%～66.4%)偏低，属于低-中热稳定煤．煤的黏温特性表明沙尔湖A、沙尔湖B、沙尔湖C、准东、宜化5种煤样均属于结晶渣，而红沙泉煤属于塑性渣．沙尔湖煤制水煤浆稳定性和成浆性均较差，难以达到水煤浆工业标准．沙尔湖煤着火点(349～361℃)较准东煤低100℃以上，沙尔湖煤的热解开始温度更低，但其焦炭更易与CO2发生反应．

Abstract

Comprehensive analysis of coal quality characteristics is the premise of clean and efficient utilization of coal types. In this paper

three kinds of high chlorine and high alkali Shaerhu coal(A

and three kinds of high alkali Zhundong coal(Zhundong

Yihua

Hongshaquan) are selected to be systematically analyzed in terms of the basic characteristics and thermogravimetric characteristics. The results demonstrate that the Na_2O content in Shaerhu coal ash(about 4.00%) is significantly lower than that in Zhundong coal ash(8.98%)

Yihua coal ash(6.47%) and Hongshaquan coal ash(9.23%)

but its Cl content(0.262%～0.491%) is higher than that of other coal samples(0.044%～0.084%)

and the Cl content in Shaerhu A is the highest(0.491%). The grindability index(129～150) of Shaerhu coal is high

but the thermal stability(TS+6=47.0%～66.4%) is low. It belonges to lowmedium thermal stability coal. The viscosity-temperature characteristics of coal show that the five coal samples of Shaerhu A

Shaerhu B

Shaerhu C

Zhundong and Yihua belong to crystalline slag

while Hongshaquan coal belongs to plastic slag. The stability and ability of coal water slurry from Shaerhu coal are poor

and it is difficult to meet the industrial standard of coal water slurry. The ignition point(349～361 ℃) of Shaerhu coal is more than 100 ℃ lower than that of Zhundong coal. The initial pyrolysis temperature of Shaerhu coal is lower

but its char is more likely to react with CO2.
