Abstract

The object of research is the effect of the ratio of the components of the pyrotechnic mixtures and the pressure of the environment on the temperature of the products of combustion and their content in high-temperature condensate. This topic has its relevance due to the recent increase in the world of pyrotechnic articles of various purposes. One of the most problematic areas is the violation of fire safety rules during their storage, transportation and use. In these modes, their premature operation, resulting in the formation of high-temperature condensed combustion products. These substances collide in different directions and pose a fire hazard to the surrounding objects (buildings and structures of various purposes, timber structures, forests, parks, etc.).

The study used a database on the temperature of combustion products of pyrotechnic mixtures and their contents in high-temperature condensate, which determine their properties in relation to fire risk during operation in external conditions. The data in the study were obtained as a result of standard thermodynamic calculations and were collected using known multiple correlation and regression methods in the form of statistical models.

The obtained calculations established a significant influence of the ratio of the components of the pyrotechnic mixtures and the pressure of the environment on the temperature of their combustion products and their content in high-temperature condensate, which allowed to determine the optimal ranges of parameters of change. This ensures new results. For comparison, calculations were made with separate experimental data for which tungsten-rhenium thermocouples with special screens were used to prevent the adhesion of condensed products and probes for their selection. The results showed that the differences between them did not exceed 8–10 %.
