摘　　要：采用α－萘酚与对氨基苯碘酸重氮盐的偶合竞争串联二级反应体系，研究了气化炉出口面积、长径比，两股射流动量比对射流携带床气化炉内混合过程的影响。结果表明：减少气化炉出口面积可以有效地改善炉内混合状况，增大两股射流之间的动量比对改善炉内混合状况有较好的作用，增大气化炉的长径比对改善炉内混合状况效果并不明显。In this paper micromixing in the jetentrained flow bed gasifier with different areas of exit, different ratios of length to diameter and different momentum ratios has been studied by means of the consecutive competitive azo coupling reactions between 1naphthol and diazotised sulphanilic acid. Results show that smaller outlet and greater momentum ratio can effectively improve mixing status, and that larger ratio of length to diameter play a less important role in mixing.
