Purpose. To study the peculiarities and conditions of appearance of heterophase inhibiting and phlegmatizing compositions generation during fire extinguishing, and to establish the relationship of combustion reaction energy with combustion temperature and dying out temperature.
Methods. Analysis, comparative evaluation of mechanisms of action of inhibiting and phlegmatizing compositions.
Findings. On the basis of the analysis of mechanisms of action of inhibiting and phlegmatizing compositions it is established that the role of generation of heterophase inhibiting and phlegmatizing compositions in fire extinguishing is not studied taking into account the thermal theory of extinguishing and the complete temperature-energy scheme of combustion reaction. Interrelation of combustion reaction energy with combustion temperature and extinguishing temperature is shown. It is proposed to calculate the required intensity of fire extinguishing compositions supply by means of the values of the critical rate of chemical reaction. In case of application of simultaneously inhibiting and phlegmatizing compositions it is proposed to take into account the influence of appearance of their generations on reaching the limiting parameters of fire extinguishing.
Application field of research. Modern approaches to the development of target fire extinguishing compositions. Development of innovative fire extinguishing compositions.
