摘要:
采用热电偶对甲烷/氧气预混火焰进行 TPD(thermocouple particle densitometry)测量,并将实验结果与激 光消光法(laser extinction method,LE)检测值进行对比,结果表明,在大部分测量区域,TPD 法检测的碳烟体积 分数与 LE 结果吻合较好;而在碳烟初生区域,使用 TPD 法测量时出现了全新的“直径稳定阶段”,该阶段的存 在加剧 TPD 在碳烟初生区域内的碳烟体积分数检测误差;通过调节 C/O 原子数比与预混气出口流速可以控制 “直径稳定阶段”的出现时间,从而更好地利用 TPD 技术.
Abstract:
The thermocouple particle densitometry(TPD)method was adopted to study the methane/oxygen premixed flame.It is shown that the soot volume fraction extracted from TPD matched well with that from laser extinction(LE)method in most areas detected.While new stage appeared in the beginning part of the sooting region, named “steady-diameter stage”,which aggravates the detection error sharply.Both the C/O molar ratio and the velocity of output are important parameters in controlling “steady-diameter stage” for the better use of the TPD method.
