摘要
将激光诱导击穿光谱技术(LIBS)应用于测量飞灰中C、Si、Al、Mg和Fe等主要元素,飞灰样品与粘结剂KBr混合压制成压片,对比分析不同环境气体(CO2,空气,N2,Ar)下飞灰等离子体特性,探究环境气体对飞灰测量的影响。研究结果表明Ar环境下光谱强度最高,N2次之,空气环境下强度稍低于N2环境,而CO2环境下不仅整体光谱强度最低,且由于背景气体CO2中存在的C元素被激发,对飞灰含碳量的测量存在严重的干扰。同时对比不同环境条件下的等离子体温度特性,结果表明Ar条件下等离子体温度最高,CO2条件下等离子体温度最低,这也表明在CO2环境下最难激发。
Abstract
Using laser-induced breakdown spectroscopy (LIBS), the main elements in fly ash, including C, Si, Al, Mg and Fe, are measured. KBr is employed as binder to press the fly ash powder to pellets. The differences of fly ash plasma characteristics in different gas environments (CO2, air, N2, Ar ) are analyzed, and their effects to unburned carbon measurements are studied. The results show that the spectral intensities obtained in argon are the highest among the four environments, and intensities in nitrogen take the second place. The intensities in air atmosphere are just a little less than those in nitrogen, while those in carbon dioxide are the least. Furthermore, carbon element in CO2 disturbs the unburned carbon analysis extremely. Comparing the plasma temperatures in different environments, plasma in CO2 atmosphere get the lowest temperature, implying it is the hardest to induce in CO2.
