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.

粒径对低温气体发生器中固体燃料气化的影响


这项工作致力于研究在推进系统的气体发生器条件下多孔材料的气化。固体燃料发动机中可以包含用于产生可燃气体的低温气体发生器。实验研究了乌洛托品粒径对其在低温气体发生器条件下气化特性的影响。为此，使用了各种组分的乌洛托品颗粒：2-3、3-5、5-7 和 7-10 mm。结果表明，存在一个粒度值，高于该值的气化特性实际上与该参数无关。粒度对气化特性的影响仅出现在小于特定粒度的粒度值上。这可以通过颗粒尺寸减小多孔床的渗透率降低来解释。
