摘要

这项工作致力于研究多孔材料在推进系统气体发生器条件下的气化。用于产生可燃气体的低温气体发生器可包含在固体燃料发动机中。实验研究了乌洛托品颗粒大小对其在低温气体发生器条件下气化特性的影响。为此，我们使用了不同馏分的乌洛托品颗粒：2-3、3-5、5-7 和 7-10 毫米。结果表明，在某一粒度值之上，气化特性实际上与该参数无关。粒度对气化特性的影响只出现在低于某一粒度值时。这是因为多孔床的渗透性随着颗粒尺寸的减小而减小。

Effect of particle size on gasification of solid fuel in a low-temperature gas generator

The work is devoted to the study of gasification of porous material under the conditions of a gas generator of a propulsion system. A low-temperature gas generator for producing combustible gases can be included in a solid fuel engine. The effect of urotropine particle size on the characteristics of its gasification under the conditions of a low-temperature gas generator was experimentally studied. For this purpose, urotropine particles of various fractions were used: 2–3, 3–5, 5–7 and 7–10 mm. It is shown that there is a particle size value above which the gasification characteristics are practically independent of this parameter. The effect of particle size on gasification characteristics only appears for particle size values below a certain size. This is explained by a decrease in the permeability of the porous bed as the particle size decreases.
