摘要
生物质与煤耦合燃烧发电由于具有较低的煤耗和低排放的特性,在“双碳”背景下在我国开始逐步推广应用。然而,生物质燃料成本较高,需要国家根据生物质掺烧量进行相应补贴,因此,生物质掺混比精准的检测将直接决定补贴政策的落实。利用^(14)C检测法可实现对生物质掺烧比的精准检测。本文将从烟气采样、样品^(14)C检测和掺烧比计算3方面详细阐述^(14)C检测法中各过程的具体方法及相应的优缺点,并对测量计算误差进行总结,最后概括了^(14)C检测过程中各阶段遇到的问题,并对未来技术的发展方向提出了参考和建议。
Biomass co-firing with coal for power generation,due to its low coal consumption and low emissions,has begun to be gradually promoted and applied in China under the"dual carbon"context.However,the cost of biomass fuel is relatively high,requiring the state to provide corresponding subsidies based on the amount of biomass mixed in.Therefore,precise detection of the biomass blending ratio will directly determine the effective implementation of subsidy policies.The^(14)C detection method can achieve accurate detection of the biomass blending ratio.This paper will detail the specific methods and corresponding advantages and disadvantages of each process in the^(14)C detection method from three aspects:flue gas sampling,sample^(14)C detection,and blending ratio calculation.It will also summarize the measurement and calculation errors,and finally outline the issues encountered at each stage of the^(14)C detection process,along with suggestions for future technological development directions.
