对于许多粉末燃料，特别是煤和生物质，焦炭燃烧是时间决定步骤。基于增强ICCD相机，一种新的装置已经开发出来，研究煤粉燃烧，主要是在层流反应器。对于焦炭燃烧表征，典型的测量参数是颗粒温度、尺寸和速度。本文介绍了该摄像装置的工作原理，并通过对煤颗粒在富CO（2）气氛中燃烧的研究，讨论了该装置的性能。
For many pulverized fuels, especially coal and biomass, char combustion is the time determining step. Based on intensified ICCD cameras, a novel setup has been developed to study pulverized fuel combustion, mainly in a laminar flow reactor. For char burning characterization, the typical measurement parameters are particle temperature, size, and velocity. The working principle of the camera setup is introduced and its capabilities are discussed by examination of coal particle combustion under CO(2)-enriched, so-called oxy-fuel atmospheres with varying O(2) content.
