【讲座简介】：
Coal characterization and prediction of slagging behavior has reached great relevance for coal-fired power plant operators. Especially, for units subject to large fuel quality variability, fuel switching and coal blending. Laser-Induced Breakdown Spectroscopy (LIBS) and Artificial Intelligence (AI) were used in the development of an on-line system for in-situ coal characterization. Demonstration of the system was carried out at several US power plants to measure elemental composition of the coal supply, heating value and ash fusion temperature with great measurement repeatability and accuracy.
煤粉特性及其结渣行为的预测与燃煤电厂的运行性能有着很大的关联。当机组需要更换燃料或需要配煤时更是如此。激光诱导击穿光谱技术和人工智能方法可以应用在原煤特性的在线系统研究上。报告将介绍美国的几所电厂应用该系统测量煤粉的元素组成，热值以及灰熔融温度，并展示系统的可重复性和准确性。
