摘　　要：生物质与煤耦合燃烧不仅可以提高生物质资源利用率,还可以达到减排效果,以符合碳交易市场要求。将生物质与煤混燃技术广泛应用于发电厂,需要对生物质掺混比进行高精度测定。然而,当前工业技术测量的速度和精度还有待提高。基于加速器质谱(AMS)的^(14)C检测法能够更准确迅速地进行^(14)C含量的测定,从而得出生物质掺混比例。本文阐述了生物质掺混比的高精度快速测定方法,并从采样方法、^(14)C含量测定、掺烧比计算模型、误差分析等方面对基于AMS的^(14)C检测方法进行了分析,并提出了测量方法的改进建议和展望,以期对生物质与煤耦合燃烧输入侧掺混比精确快速测定提供科学参考和建议。The coupling combustion of biomass and coal can not only improve the utilization rate of biomass resources,but also achieve emission reduction effects to meet the requirements of the carbon trading market.The widespread application of biomass and coal co-combustion technology in power plants requires high-precision determination of biomass blending ratio,and the measurement speed and accuracy of current industrial technology need to be improved.The ^(14)C detection method based on accelerator mass spectrometry(AMS)can determine the ^(14)C content more accurately and quickly to obtain the blending ratio of biomass.The high-precision and rapid measurement method of biomass blending ratio was elaborated on in this article,and a comprehensive research progress analysis on the ^(14)C detection method based on AMS from the aspects of sampling method,^(14)C content measurement,blending ratio calculation model and error analysis was conducted.Suggestions and prospects for improving the measurement method were proposed,in order to provide scientific reference and suggestions for the accurate and rapid determination of the blending ratio on the input side of biomass and coal coupling combustion.
