碳氢燃料不完全燃烧所产生的碳黑是一种仅次于二氧化碳的温室物质,开展碳氢火焰中碳黑的检测研究对于充分理解碳黑生成机理、控制碳黑排放有着重要的作用.本文综述了碳氢火焰中碳黑检测的常用方法,包括:热泳探针取样及电镜分析、热电偶颗粒密度法、消光法、激光诱导炽光法、双色法、发射CT法,并详细介绍了各种检测方法的基本原理及应用状况.碳黑检测的发展趋势是要实现对碳氢火焰中温度、碳黑浓度、碳黑尺寸等多参数的多维分布的在线检测;不仅要面向实验室小型燃烧火焰,还要面向工业应用中大尺度火焰;而且对于高压、零重力、微重力等燃烧火焰也要提供合适的检测手段.
Carbon black generated by the incomplete combustion of hydrocarbon fuels is a greenhouse substance second only to carbon dioxide, and the research on the detection of carbon black in the flame of carbon flame plays an important role in fully understanding the formation mechanism of carbon black and controlling carbon black emissions. The common methods of carbon black detection in hydrocarbon flame are summarized, including: sampling and electron microscopy of thermophoresis probe, thermocouple particle density method, extinction method, laser-induced incandescence method, two-color method, emission CT method, The basic principle and application status of various detection methods.The development trend of carbon black detection is to realize on-line detection of the multi-dimensional distribution of multi-parameters such as temperature, carbon black concentration, carbon black size in the hydrocarbon flame, Burning flame, but also for large-scale industrial flame applications; but also for high pressure, zero gravity, microgravity and other combustion flames also need to provide appropriate detection means.
