激光诱导击穿光谱分析法在煤质分析中的应用研究

Application of Laser Induced Breakdown Spectral Analysis in Coal Quality Analysis

当前煤质分析主要是采用人工取样和化学检验,其时效性差,误差较大。为此将无放射性激光诱导击穿光谱分析法应用于煤质分析中,实现了在线检测,无放射性和非接触式快速检测,准确性高,为选煤生产工艺提供基础。

At present,the coal quality analysis mainly adopts manual sampling and chemical inspection,which has poor timeliness and large error.Therefore,the non-radioactive laser induced breakdown spectral analysis method is applied to coal quality analysis,which realizes on-line detection,non-radioactive and non-contact rapid detection,high accuracy,and provides the basis for coal preparation production process.
