FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire-fighting equipment and can be used to measure heat dissipation power of combustion source and determination of fire-extinguishing efficiency of powder fire-extinguishing means in conditions of unsteadiness of gas-powder flow caused by change of powder concentration and gas jet velocity in each point of flow in time. Proposed method allows to measure heat dissipation capacity at fire burning and fire-extinguishing powder impact. Heat removal capacity is measured by means of determination of difference of powers of heat release of incandescent filament introduced into combustion source before and after fire-extinguishing powder supply.
EFFECT: technical result is higher accuracy and information value of determining heat absorption by powder fire-extinguishing means during combustion of analysed liquid.
