提高原煤在线组分识别精度的研究

Research on Improvement of Precision of On-Line Identification of Raw Coal Component

介绍了基于双能γ射线透射法的原煤在线组分识别模型,对测量过程中的误差成因进行了阐述,论证了质量厚度和组分几何分布存在跨度变化会引入动态测量误差,提出了实际应用中提高原煤组分在线识别精度的相应对策。

The paper describes the dual energy gamma - ray transmission based on - line raw coal component identification model and discussess on the cause resulting in error during measurement. It is shown that the dynamic error is caused by variation in mass thickness and component geometric distribution. The countermeasures for improvement precision of on - line identification of raw coal is put for-word in the paper.
