高氯高碱煤煤质特性与热转化特性对比研究
Comparative Study of High-Chlorine/Alkali Coal:Properties and Thermal Conversion Behavior
摘要
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,B,C),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 Na2O 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 low-medium 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.关键词
