摘　　要：文章利用空气中不同成分在磁场中受力方向不同的原理,提出在燃烧系统中空气侧管路上增设磁场,采用梯度磁场制备富氧空气用于助燃。实验研究了空气侧增设磁场对燃烧的影响。结果表明,增设磁场后炉膛温度有所升高,烟气中残氧量和可燃物质含量均降低,该装置能够大幅度提升可燃物质与氧气的燃烧反应,同时不会增加NO_(x)排放量。Based on the principle that different components in the air are subjected to different forces in the magnetic field,a magnetic field is added to the air pipe of the combustion system to prepare oxygen-rich air for combustion.The effect of the air flow through magnetic field on combustion was experimentally studied.The results show that the temperature in the furnace increases and the residual oxygen and combustible matter in the flue gas decrease after the addition of magnetic field,that magnetic field can improve the combustion reaction between combustible substances and oxygen without increasing the emission of NO_(x).
