煤油催化重整可燃燃气发生器的试验研究

Experimental Researches on Flammable Gas Generator of Kerosene with Catalytic Reforming Reaction

设计了新型煤油催化重整燃气发生器，在较大油量和较高压力情况下，进行了一系列相关参数的影响试验．试验结果表明：在催化温度较高、头部余气系数保持在0．6～0．8时，其出口燃气温度为400～700℃，可燃气体成分占15％～30％，氢气体积分数最高可达16％，从而可为超燃冲压发动机提供良好的高温含氢可燃燃气，有利于超燃室内的点火和稳定燃烧．

A new type of kerosene gas generator for catalytic reforming reaction was designed. Under high fuel flow rate and high pressure, the effects of different parameters on catalytic reaction were studied through a series of experiments. The resalts show that the exit flammable gas temperature of 400-700 ℃ and the gas composition of 15%-30% will be obtained when the excessive air coefficient is controlled between 0. 6-0. 8 and the catalytic temperature reaches about 500-700 ℃. The hydrogen quantum of 16% will be achieved in the high temperature fuel-rich flammable gases, which can be introduced into the scramjet and will be helpful to its ignition and stable combustion process.
