| 1 | 激光波长对煤激光诱导击穿光谱特性影响的试验研究显示文摘我国电站入炉煤种复杂多变,实时快速获取煤质成分对保障锅炉的安全、高效、低污染运行具有重大意义。将激光诱导击穿光谱(LIBS)技术应用于燃煤煤质测量,观测了不同波长激光(355,532和1 064nm)诱导产生的等离子体时间演变特性和不同电离特性元素的谱线时间特性,对比了出现屏蔽效应时的能量阈值随激光波长的变化特征,并研究了激光波长对煤LIBS光谱特性的影响规律。结果发现:使用532nm激光作为激发光源时,煤LIBS光谱具有最强的谱线信号强度,且出现等离子体屏蔽效应的能量阈值也较高,是一种较理想的激发光源,为LIBS技术在煤质测量领域的工业应用提供了实验依据。 | 钱燕 钟厦 何勇 Ronald Whiddon 王智化 岑可法 | 2017 | 光谱学与光谱分析2017，37，6： | 9 |
| 2 | Release characteristic of different classes of sodium during combustion of Zhun-Dong coal investigated by laser-induced breakdown spectroscopy显示文摘Serious fouling and slagging problems are associated with the combustion of Chinese Zhun-Dong coal due to its high content of sodium(Na). Understanding the release characteristic of Na during the combustion is essential to viable utilization of this coal. In this work, coal samples were treated with a sequence of solvents: water(H2O), ammonium acetate(NH4Ac), hydrochloric acid(HCl), and the release characteristics of various classes of Na during coal combustion were investigated using the technique of laser-induced breakdown spectroscopy. The relative contribution of various Na classes to the Na release during each combustion stage was found to be similar, in the order of H2O-soluble Na [ NH4 Acsoluble Na [ HCl-soluble Na [ insoluble Na. Sodium released during the devolatilization stage can be attributed to each of the sodium classes. After the devolatilization stage,H2O-soluble Na and NH4Ac-soluble Na dominated the Na release during both char and ash stages. Over 64 % of the total Na released during combustion comes from the H2O-soluble Na, which suggests that the Na release during the combustion of Zhun-Dong coal can be reduced effectively after treatment by H2 O washing. | Yong He Kunzan Qiu Ronald Whiddon Zhihua Wang Yanqun Zhu Yingzu Liu Zhongshan Li Kefa Cen | 2015 | Science Bulletin2015，60，22： | 8 |
