利用在小型流化床试验台上进行了糠醛渣、褐煤及其混合物的着火和燃尽试验。研究了不同混合比下的着火温度的确定，结果表明褐煤中加入糠醛渣后的着火温度明显发生变化。利用烟气分析仪对样品燃烧后所产生的CO2进行跟踪测量，得出各种样品的燃尽时间。在燃尽试验中考察了混合比、床层温度和粒径对燃尽的影响。结果表明燃尽时间随着床温的增加而减小，而随着粒径的增加而增加。混合比对燃尽时间的影响与其它两种因素不同，在一定混合比范围内燃尽时间随着糠醛渣的增加而减小。实验结果表明：提高床层温度、增大燃料混合比，有助于减少燃尽时间。%Experimental study on ignition and burnout characteristics of furfural residue,lignite and their mix-tures was conducted in small circulating fluidized bed. This paper mainly focuses on the determination of igni-tion temperature at different mixing ratios. The results show that the ignition temperature of lignite after the ad-dition of furfural residue has a significant change. The flue gas analyzer was applied to tracking and measure-ment for carbon dioxide produced form samples combustion, and then the burnout time of samples was ob-tained. The influence of mixing ratios,bed layer temperature and particle size was analyzed. The results show that burnout time decreases with the increase of bed layer temperature and increases with the increase of parti-cle size. The influence of mixing ratio to burnout time is different from that of the other two factors. In a certain range of mixing ratio,the burnout time of composite sample decreases with the increase amount of furfural resi-due. The experimental results show with the increase of bed layer temperature,mixing ratio,the burnout time of composite sample can be decreased.
