摘要
为确定高效低污染燃烧的条件 ,研制了火焰特性实验装置 .在此装置上研究了助燃剂预热温度及氧体积浓度对丙烷火焰特征的影响 .实验中 ,助燃剂预热温度变化范围为 380～ 1 0 0 0℃ ,氧体积浓度变化范围为 2 1 %～ 2 % .实验表明助燃剂温度及其含氧量对火焰特性有非常显著的影响 ,高温低氧条件下的火焰体积、火焰亮度与颜色、火焰形状等特性明显改变 .此外 。
In order to study flame characteristics in conditions of air oxygen content ranging from 21% to 2% and air temperature ranging from 300 ℃ to 1 000 ℃, a furnace with small size chamber was constructed. The oxidizer was heated electrically and diluted by nitrogen. Propane was used as the fuel. It has been observed that the volume, shape and color of the flame changed significantly in the test condition mentioned in the paper. The results confirmed the influence of oxygen and temperature on the fuel combustion.
