Purpose. To research the parameters of the fire extinguishing powder supply.
Methods. Experimental determination of the feed intensity and range of the fire extinguishing powder jet.
Findings. Studies of the parameters of the supply of fire extinguishing powder composition to the fire center were carried out, the values of the intensity and range of its supply were obtained using a standard and modernized powder fire extinguisher. According to the results of tests, it was found that at the same initial pressure, amount of powder and spray nozzle in the upgraded fire extinguisher, the range of the jet, the area of spraying and the intensity of supply increases. The effectiveness of extinguishing using the proposed design of the fire extinguisher has been practically proven.
Application field of research. The results of the research can be used to optimize the design of the powder extinguisher, the shape and size of the spray nozzle, as well as to improve the tactics of extinguishing fires using powder extinguishers.
