摘要

对3种含硫量差异明显的煤进行掺配

采用库伦滴定法对单煤和混煤分别在815、900、1 000℃下灼烧的灰样进行分析

得到相应的固硫率。测定结果表明:混煤的固硫率受温度等因素的影响较大

不具有可加性;(Ca+Mg)/S摩尔比对固硫率的影响随着温度的升高而减弱;在较低的温度(815℃)下

配煤可以提高煤自身的固硫率。

Abstract

Three coal sorts with substantially different sulfer content have been mixedly blended

and the ash samples of said coal sorts being analysed at 815 ℃

900 ℃

and 1 000 ℃ respectively by using Coulometric Titration Method

and the corresponding sulfer-retention rate being obtained.Result of measurement shows that the sulfer-retention rate of blended coals is greatly affected by the temperature and other factors

having no additivity.The influence of(Ca+Mg)/S molar ratio upon the sulfer-retention rate reduces with the temperature increase

at a lower temperature(815 ℃)

coal-bending can enhance the sulfer-retention rate of the coal proper.
