Background. The work is devoted to the problem of evaluating the efficiency of extinguishing fires of solid combustible substances and materials by a static electric field in the modes of fire controlled by load and fire controlled by ventilation. Materials and methods. To assess the efficiency of extinguishing fires of solid combustible substances and materials with a static electric field, a mathematical model has been developed based on the equations of forced diffusion of the electronic and ionic components of the flame torch when an external static electric field is applied, taking into account the intrinsic electrical properties of the flame torch. Results. Analytical dependences of the parameters of forced diffusion of electric charge carriers in the area of the primary reaction zone of the flame torch under the influence of a homogeneous and inhomogeneous static electric field are obtained, the dependence of the extinguishing time of the fire on the configuration and intensity of the external electric field is shown. Conclusions. The developed mathematical model makes it possible to obtain the values of the fire extinguishing time by a static electric field for various thermodynamic parameters of an internal fire and schemes for applying an external static electric field. The model can be applied in the development and experimental studies of fire extinguishing systems using a static electric field.
