摘　　要：经过上百年的煤燃烧研究为煤炭的工业应用奠定了坚实的基础,但是煤燃烧的内部稳定性、着火的机制的转变以及污染物的生成依然没有明确的理论指导,光学测量技术的发展为研究燃烧机理提供了合适可靠的工具,燃烧诊断在全球的学术界研究成为热点。本文综述了煤粉燃烧的激光诊断研究特性:着火、燃烧稳定性、挥发分燃烧等,并分析国内外的研究现状。After hundreds of years of research on coal combustion,a solid foundation has been laid for the industrial application of coal.However,there is still no clear theoretical guidance on the internal stability of coal combustion,the transformation of ignition mechanisms,and the generation of pollutants.The development of optical measurement technology provides suitable and reliable tools for studying combustion mechanisms,and combustion diagnosis has become a hot topic in the global academic community.This article reviews the research characteristics of laser diagnosis for coal powder combustion,including ignition,combustion stability,volatile combustion,etc.,and analyzes the current research status at home and abroad.
