用化学分析、Ｘ射线能谱、扫描电子显微镜、偏光显微镜、激光粒度分析仪等仪器对沸腾炉燃烧所产生的底灰的化学成分、颗粒形貌、粒度、物理性质和工艺性质等进行了系统的分析，并与全国电厂煤粉炉产粉煤灰的特性进行了对比．结果表明，沸腾炉产底灰具有形态不规则、矿物相中无莫来石矿物、未燃烬炭量低、细度低、比表面积小、火山灰活性高等特点，为沸腾炉底灰的加工利用提供了重要的科学依据．
The chemical compositions, particle morphology, particle size, physical properties and process properties of the bottom ash generated by the combustion in a boiling furnace were systematically analyzed by means of chemical analysis, X-ray energy dispersive spectroscopy, scanning electron microscopy, polarizing microscope and laser particle size analyzer Analysis, and with the national power plant pulverized coal ash production characteristics were compared. The results show that the bottom ash of the fluidized bed furnace has the characteristics of irregular shape, no mullite mineral in the mineral phase, low unburned carbon content, low fineness, small specific surface area and high activity of pozzolana, which provides the processing and utilization of the bottom ash of the fluidized bed Important scientific basis.
