| 摘 要： | 为了研究输送带速度和光谱仪安装高度对近红外在线检测秸秆-煤混燃物的影响。该研究收集并制备秸秆样品80个、煤样品9个,制备秸秆质量分数为70%～99%的秸秆-煤混燃物样品120个(质量分数增量为1%)、秸秆质量分数为1%～30%的秸秆-煤混燃物样品120个(质量分数增量为1%)。在输送带速度分别为300、600、1 000和1 400 mm/s,光谱仪安装高度分别为50、56、59和65 mm的条件下,使用Thermo Fisher Scientific Antaris Target FT-NIR型光谱仪获取样品近红外光谱。使用线性判别分析法建立定性分析模型,使用偏最小二乘法建立定量分析模型。结果表明,光谱仪安装高度建议为50～65 mm,输送带速度建议小于300 mm/s。该研究可为近红外光谱法在线定性和定量检测生物质-煤混燃物的方法学研究和相关仪器设计提供参考。

| Abstract: | Abstract: In order to study the effect of conveyor speed (V) and spectrometer installation height (H) on on-line measurement of straw-coal blends using near infrared reflectance spectroscopy (NIRS). A total of 80 straw samples, 9 coal samples, 120 straw-coal blend samples with straw content from 70% to 99% (1% wt/wt increments) and 120 straw-coal blend samples with straw content from 1% to 30% (1% wt/wt increments) were prepared. Spectra were obtained using a Thermo Fisher Scientific Antaris Target FT-NIR spectrometer at V=300, 600, 1 000, 1 400 mm/s and H =50, 56, 59, 65 mm, respectively. Linear discriminant analysis method was used for qualitative analysis and partial least squares regression was used for quantitative analysis. The spectrometer installation height is suggested to be 50-65 mm and the conveyor speed less than 300 mm/s. This study can provide references for the methodological research and related equipment design of on-line qualitative and quantitative measurement of biomass-coal blends using NIRS. |
