摘　　要：在煤粉燃烧领域，随着人们普遍对锅炉低负荷燃烧、开发新式燃烧器等方面问题的重视，煤粉的燃烧特性成为最基础也是最关键的课题之一，而其与颗粒直径的关系，综观以往的有关研究，却众说纷坛。文中深刻总结了以往的试验研究及理论研究，指出了其中存在的问题，澄清了研究的误区，提出了正确的研究方向，对这一问题的深入研究有重要的意义。In the field of pulverized coal firing, low load combustion of bOiler anddevelopment of new burner ect. are geherally concerned. Consequently, ignition cbaracte-ristics of pulverized coa1 became one of the most basic and key issues, however, itsrelationship to particle diameter has various opinions from relevant researches. Afterreviewing previous experimental researches and theory studies on this subject, the authorspointed out existing problems, corrected some mistakes, and proposed correct study direc-tion8, which is very important to deep investigation in the field.
