Abstract Systematic experiments were performed on an innovative pulse detonation steam superheater (PDSS) for determining the concentration limits of detonation of the ternary mixtures propane–oxygen–steam at normal atmospheric pressure. The experiments were carried out while varying the fuel–oxygen equivalence ratio (from 0.3 to 1.7) and the volume fraction of steam (from 0 to 0.7). Cyclic detonation of ternary mixtures was shown to be able to create a high-temperature gas medium that has a temperature above 2250 K and contains to 80% highly superheated steam and to 20% CO 2 , and also CO, O 2 , and H 2 at low concentrations at atmospheric pressure. Such medium was proposed to be used for advanced treatment of household and industrial organic waste to produce a gas mixture of CO and H 2 . Because the filling of PDSS with the “cold” ternary gas mixture is periodic, the increase in the temperature of its walls and internals is insignificant, and PDSS can be built from conventional (not necessarily refractory) construction materials.

丙烷-氧气-蒸汽三元混合气的循环爆轰用于生产高过热蒸汽

摘要 在创新的脉冲爆轰蒸汽过热器 (PDSS) 上进行了系统实验,以确定正常大气压下丙烷-氧气-蒸汽三元混合物的爆轰浓度极限。实验是在改变燃料-氧当量比(从 0.3 到 1.7)和蒸汽的体积分数(从 0 到 0.7)的同时进行的。三元混合物的循环爆轰能够产生温度高于 2250 K 的高温气体介质,其中含有 80% 的高度过热蒸汽和 20% 的 CO 2 ,​​以及 CO、O 2 和 H 2在大气压下低浓度。这种介质被提议用于家庭和工业有机废物的深度处理,以产生 CO 和 H 2 的气体混合物。
