摘要
针对强旋流平焰燃烧采用高温低氧燃烧条件,应用粒子成像测速技术(PIV)对烧嘴下方的主要燃烧区速度场进行了测量,同时对炉内温度场,排烟口NOx进行测量。经过实验研究,在高温低氧燃烧条件下,燃烧稳定,燃气燃烧完全,燃烧区温度分布均匀,NOx生成量下降到30×10-6。通过蓄热室,空气由20℃预热到200℃,烟气温度由800℃降低到80℃,达到了节能环保的效果。
Based on the single swirl burner flat - flame combustion, the mode of fuel depth entering is adopted. The article measures central combustion speed field under burner by Particle Image Velocimetry (PIV) technique, as the same time temperature field in the furnace and NO. formation are measured. By experiment research, it appeared that with HTAC technology, combustion was stabilization, and fuel completely burnt, temperature distributing got uniformity, NO, formation decreased to 30 × 10^-6. Though regenerator, air temperature increased from 20℃ to 200℃, smoke temperature decreased from 80092 to 8092, it achieved the effect of energy conservation and environment protect.
