在煤粉浓缩燃烧器中加入示踪颗粒，利用激光多普勒测速技术对湍流流场的速度场及湍流参数进行测量研究，通过自动数据采集及处理分析系统，获得不同钝体结构的煤粉浓缩燃烧器的速度及湍流强度分布，为钝体的选型和燃烧器的设计、着火燃烧机理的分析提供了理论依据 Tracer particles were added to the pulverized coal enrichment burner, and the velocity field and turbulence parameters of the turbulent flow field were measured and measured by laser Doppler velocimetry. Pulverized coal with different blunt body structure was obtained through automatic data acquisition and processing analysis system Concentration of the burner speed and turbulence intensity distribution for the selection of bluff body and burner design, combustion theory provides a theoretical basis for combustion
