Theoretical models of large-scale combustion of hydrocarbon fuels are considered. Semi-empirical model of burning fireball is offered. The analysis of the literature on modeling of high-intencity heat flow in the various fields of engineering and technology is lead. For the first time the use of chemical energy of pyrotechnic composition is offered for real fires heat flow modeling in oil and gas industry. The technique of pulse heating experiment on concrete samples in the laboratory conditions is developed. Mathematical modeling of heat and mass transfer processes is lead in the system «pyrotechnic composition – concrete sample». Adequacy of the model to experimental data is establised.
