摘　　要：煤自燃引发的火灾不仅会造成人身伤害及经济损失,同时还会破坏环境、污染大气,因此准确的判定煤的自燃倾向性对于火力发电厂运煤系统设计、防火设计以及运行检修具有重要的意义。分析了火力发电厂设计中采用的煤自燃倾向性分类方法存在的问题及目前国家标准煤自燃倾向性色谱鉴定方法的优点,指出在火力发电厂设计时应采用煤自燃倾向色谱鉴定方法作为煤自燃倾向性判定依据。介绍了两种新的煤自燃倾向性鉴定方法,在今后可以作为新的研究方向。The fire caused by coal spontaneous combustion will not only cause personal injury and economic losses,but also damage the environment and pollute the atmosphere.Therefore accurate judging spontaneous combustion tendency of coal for the coal handling system in thermal power plant design,fire protection design and operation and maintenance has important significance.It is important to accuratelydeter minethe tendency of spontaneous combustion of coalfor design of coal handling system and fire protection and operation and maintenance in thermal power plant.The existing problems of the classification method of tendency of spontaneous combustion of coal for plant design and the advantage of identification method of oxygen adsorption with chromatograph is analyzed,and points out that identification method of oxygen adsorption with chromatograph can be used in the design of the thermal power plant.This paper introduces two new identification methods of tendency of spontaneous combustion of coal,which can be used as a new research direction in the future.
