摘要:It was theoretically grounded and experimentally confirmed that adding nitrogen to the aerosol of inorganic potassium salts considerably increases efficiency of the fireextinguishing of the obtained binary mixture. As a result of the studies we determined that the addition of nitrogen to the aerosol reduces the fireextinguishing concentration of the components of the final binary mixture by 30 %. Experiments confirmed that the optimal ratio of the components in the mixture of a binary mixture, which consists of the aerosol is 10 g/m3 and nitrogen – 12.1 %. It is fireextinguishing for the diffusion flame of heptane and simultaneously provides lifesafe concentration of oxygen. It was found that high efficiency of binary aerosol nitrogen mixture is achieved due to the synergy of the components of the mixture. We defined the value of intensity and decrease in the temperature of the diffusion and kinetic flame with its presence in the aerosolnitrogen mixture. The study of fireextinguishing efficiency of the aerosolnitrogen mixtures is necessary to determine the conditions and methods of the fire extinguishing by the mixture in closed areas.Received dependencies and specifications of aerosolnitrogen mixtures can be the foundation for the creation of ecologically clean, cheap, and simple in the production and operation firefighting tools with high firesuppression efficiency, which can be used for the fire suppression in the areas of temporary stay of people and living organisms without an apparent damage to them as a result of volumetric fire extinguishing by the described mixtures.
