摘要
针对传统煤质分析方法检测成本高、工作效率低、后续处理复杂等问题,介绍了国内外近红外光谱技术在煤质分析方面的研究现状,并对近红外光谱技术应用于煤质分析的发展趋势进行展望。近红外光谱技术可准确、快速检测煤中水分;近红外光谱技术测硫时选择性高、重复性好;测氢时样品用量少,操作简单,分析成本低;测定工业分析和发热量时,可大幅减少分析时间,准确度高。提出未来应加快煤质分析中近红外光谱仪的研制,加强近红外光谱在煤质分析的标准编制,研究近红外光谱在其他煤炭检测项目中的应用,加强近红外光谱技术与其他技术相结合的模型研究,研究煤质项目谱图数据库。
The problems with traditional coal quality analysis were high cost,low efficiency and complicated subsequent processing. The ap-plication of near infrared spectroscopy technology at home and abroad in coal quality analysis were introduced. For moisture,hydrogen,proximate analysis and calorific value,the near infrared spectroscopy technology had the advantages of accurate and quick,great selectivityand repeatability,short analysis time and accurate respectively. At last,the authors pointed out that the establishment of correspondingstandard and coal quality spectrum database,the application of near infrared spectroscopy in others detecting items,the models combiningnear infrared spectroscopy with others technologies should be strengthened.
