An experimental gas generator installation was established and applied to research the self - ignition behavior of ethanol while it was injected into hot oxidizing gas mixture produced by decomposing of h2o2 with high concentration 装置中质量分数为90 %的过氧化氢溶液由高压气挤推,通过催化床完成催化分解,产生高温气体;质量分数为97 %的酒精溶液经由分布喷嘴喷入过氧化氢分解气体中发生自燃,从而提高气体温度。
