摘    要:在多功能燃烧脱硝实验装置上,对不同种类生物质再燃脱硝进行了实验研究,考察了生物质特性及实验工况对脱硝效果的影响。结果表明,生物质再燃能够取得55%~70%的脱硝效率,当实验参数选取在一定范围内时,随着再燃区温度的提高、过量空气系数的减少、再燃比的增加、NO初始浓度的提高以及燃料粒径的减小,NOx还原率逐渐提高。相同的实验工况下,玉米秸再燃取得的脱硝效果最好,麦秸、花生壳次之,杨木屑较差。

关 键 词:生物质  再燃  脱硝

Abstract:A series of experiments were conducted in a multiple functional combustion test bed with several kinds of biomass as reburning fuel to reduce NOx. The character and experimental parameters are emphasized to examine the influences on NOx reduction. The results show that biomass could get about 55% to 70% NOx reduction. Within a certain range of the parameters tested, NOx reduction increases with the increasing temperature of reburning zone and initial concentration of NO, and with decreasing excess air ratio and diameter of fuel particle. Under the same test conditions, cornstalk gets the highest NOx reduction and wheat straw, peanut shell,wood ship follow in turn.
Keywords:biomass energy  reburning  NOx reduction
