Abstract

Purpose. To improve the device for supplying fire extinguishing powder compositions, to investigate the parameters of supplying fire extinguishing powder by means of the proposed device.

Methods. Experimental determination of the range of fire extinguishing powder jet and working pressure in the fire extinguisher cylinder. Theoretical calculations of the fluidity of fire extinguishing powder composition depending on working pressure in the fire extinguisher cylinder.

Findings. For parallel radiating and receiving surfaces, located arbitrarily relative to each other, the analytical expression is obtained that allows determining the configuration factor of an element of receiving surface by emitting surface which have the shape of an arbitrary convex polygon.

Application field of research. Determination of the fire breaks between buildings, taking into account the individual characteristics of the objects calculated – gabled roof made of combustible materials.
