摘要:

采用红外反射法研究飞灰中碳的质量分数.在自行设计的实验台架上,对碳质量分数为3%~14%的烟煤飞灰样品进行测量分析.测量结果表明,样品厚度对反射光强有影响,当样品厚度在1 cm以上时红外反射光强较稳定;当不同样品间碳的质量分数近似相同时,飞灰粒径对反射光强有影响,反射光强与飞灰粒径成正比;对于碳质量分数渐变的多个样品,粒径对反射光强影响不大,红外光反射比能够反映飞灰中碳质量分数的变化.

Abstract:

Carbon mass fraction in flying ash was analyzed by infrared reflection method. Bituminous coal samples with carbon mass fraction between 3% to 14% were measured on the self-designed experiment setup. Results showed that the sample thickness influenced reflected light intensity, the reflected light intensity was more stable when the sample thickness was over 1cm. Particle size impacted the reflected light intensity when the carbon contents were similar in different samples, and the reflected light intensity was proportional to the particle size .In the samples with changing carbon mass fraction, particle size had little impact on reflected light intensity and reflected light intensity ratio can reflect the carbon mass fraction in flying ash.
