Abstract
Most interesting and important gas-dynamic and kinetic parameters of combustion, explosion and detonation of the combustible ammonia/oxygen system in the range from the lower to the upper concentration limit with a change in the initial pressure and temperature are presented. From the point of view of explosion safety, the most important data are on the critical initiation energy, which allows analyzing the relative danger of various mixtures. Critical energy is defined as the minimum energy of the initiator that ensures the propagation of combustion and detonation waves in the mixture under study: the lower the critical initiation energy, the more dangerous the mixture.
