6、起草单位:煤炭科学研究总院煤炭分析实验室。本标准主要起草人:皮中原、姚恩题。本标准为首次制定。准标网www.zhunbiao.com免费下载MT/T924-2004工业型煤热稳定性测定方法1范围本标准规定了工业型煤热稳定性测定所用的试样、仪器设备、测定步骤、结果表达和方法的精密度。本方法适用于各种工业型煤。2规范性引用文件下列文件中的条款通过本标准的引用成为本标准的条款。凡是注日期的引用文件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的各方研究是否可使用这些文件的最新版本。凡是

7、不注日期的引用文件，其最新版本适用于本标准。GB/T483煤炭分析试验方法一般规定MT/T915工业型煤样品采取方法定义和术语下列术语和定义适用于本标准.3.1工业型煤industrialbriquette由各种煤加工成具有一定形状、尺寸和强度的煤制品称为型煤。用作工业燃料、工业原料及其他工业用途的型煤称为工业型煤。3.2热稳定性thermalstability型煤在高温燃烧或气化过程中对热的稳定程度，也就是型煤在高温作用下保持原来粒度的性质。方法提要将一定数量的型煤，在(850士15)℃的马弗炉中隔绝空气加热30min，冷却

8、后称量，筛分5min，以粒度大于13mm的残焦质量占各级残焦质量之和的百分数作为热稳定性指标BTS+=;以粒度小于3mm的残焦质量占各级残焦质量之和的百分数作为热稳定性辅助指标BTS_,,5仪器设备5.1马弗炉:恒温区不小于100mmX230mm。带有恒温调节装置并能保持在(
