| 为解决生物质电厂灰渣的资源化利用问题，从长三角地区10家生物质电厂采集灰渣并进行分析。采用X射线衍射仪、X射线荧光光谱仪、扫描电子显微镜等表征设备，系统分析了生物质电厂灰渣的物相组成、化学特性及微观形貌，探索了灰渣的资源化利用方式。研究结果显示：生物质电厂所用的燃料在很大程度上影响灰渣的化学组分；生物质底渣中SiO2、CaO和Al2O3质量分数多，其中第9家生物质电厂的底渣中含SiO2质量分数最高，达到67.55%；生物质飞灰中含有更多的CaO、Cl?和K2O等物质，并且颗粒较细，孔隙较少，一定程度上可填补生物质底渣的孔隙；生物质底渣和生物质飞灰的协同应用可优化Ca与Si之比，为生物质电厂灰渣的建材化利用提供了新途径。 |

| In order to solve the problem of resource utilization of biomass power plant ash, ashes were collected and analyzed from 10 biomass power plants in the Yangtze River Delta region. The phase composition, chemical characteristics, and micro-morphology of biomass power plant ashes were systematically investigated through various characterization equipment including X-ray diffraction, X-ray fluorescence spectroscopy, and scanning electron microscope, aiming to explore potential resource utilization pathways. The results indicate that the fuel used in biomass power plants largely affects the chemical composition of the ash. The mass fractions of SiO2, CaO, and Al2O3 in the biomass bottom slag are high. Notably, the biomass bottom ash from the 9th biomass power plant shows the highest SiO2 mass fraction at 67.55%. In contrast, biomass fly ash contains elevated levels of CaO, Cl? and K2O, with finer particles and fewer pores. The synergistic application of biomass bottom ash and biomass fly ash can optimize the ratio of Ca and Si, providing a novel approach for the utilization of biomass power plant ash residues in building material production. |
