Additive Effects on Soot Formation in Diffusion Flames

进行研究以确定一系列添加剂的效果 C H /O /N扩散火焰中碳烟的形成。 添加剂应 研究的包括：P（OCH 3）3、POBr 3、Sb（OCH 3）3、SbBr 3、CH 3Br、MoBr 4和 (NH4)6M07024。 添加剂的效果由以下因素决定： 在燃料或空气流中不加和加添加剂时的测量：火焰 使用细线热电偶的温度曲线;位置和 C2*、CH* 和碳烟颗粒的发射强度， 带宽摄影.用朗缪尔法测定总正离子浓度 探针; OH浓度使用紫外光吸收;温度将 也可以从OH旋转线比测量;和总烟灰 使用双波长激光消光技术进行浓缩。

Research is conducted to determine the effects of a series of additives on soot formation in C H /O /N diffusion flame. The additives to be studied include: P(OCH3)3, POBr3, Sb(OCH3)3, SbBr3, CH3Br, MoBr4, and (NH4) 6M07024. The effects of the additives are to be determined by measureing without and with additives added to fuel or air flow: flame temperature profiles using fine wire thermocouples; the location and intensity of emission from C2*, CH*, and soot particles using selected bandwidth photography; total positive ion concentrations using langmuir probes; OH concentrations using UV light absorption; temperatures will also be measured from OH rotational line ratios; and total soot concentrations using two wavelength laser extinction techniques.
