When working in conditions of dense urban development and the extraction of a piece of stone, the question arises of organizing gentle destruction modes, which requires the use of pyrotechnic compositions operating in deflagration mode. In such compositions, ammonium nitrate, ammonium perchlorate and various nitrates are used as an oxidizing agent. Magnesium is often used as a fuel. In this paper, we studied the combustion of a three-component mixture of sodium nitrate, magnesium, and carbon, obtained by carbonizing the walnut shell, or by grinding the elements of gas masks. Thermodynamic calculations of the combustion of a mixture with different content of components were carried out and the combustion characteristics of the mixture NaNO3/Mg/C(60/20/20) were measured. The prospect of using such a mixture in gas generator cartridges is shown. Presents methods for determining the burning rate, which is easy and affordable, continuous measurement of the current mass or linear burning rate. The results of the experiments are presented after processing with the help of modern programs. As well as the influence of the size of the components and their relationship to the burning rate.
