The ways of modernization of portable fire extinguishers for extinguishing forest fires

Goal. Ensuring reliable and efficient operation of portable and manual fire extinguishing devices in emergency situations involving fire hazard forests of Ukraine is one of the urgent tasks. While the effectiveness of existing fire extinguishers and fire protection systems for using them in liquidation of fires on the territory of the rural economy is problematic. For their application it is necessary to have electrical energy, the compressor, which is a source of compressed air, a number of vessels under high pressure, the connecting fittings. Technique. Use as an energy source solid gasifica compounds (TOC) is constrained by low level of knowledge about the processes occurring in the devices of this class. The creation of an Autonomous funds with hazoheneratsiy devices (GHP) that consume energy CBT for protective and preventive measures in emergency situations requires the solution of several problems. One of them is the interaction of the combustion products of the CBA with the active substance. The results of Heating the liquid thermal conductivity, and the presence of jets of combustion products when triggered, causes intense GHP convective flows in the liquid. The intensity varies with device applicable attachments and its location in the free volume of the cylinder. Scientific novelty. For the task applied boundary conditions of the fourth kind for a system of two napavalley bodies, in which different initial temperature and the initial time of the body shown in juxtaposition. The decision held for the plane case. The result shows that the application of CBT to boost liquid fire extinguishers require additional measures to reduce the temperature of the gas mixture. The practical significance. The depth of heating of the liquid substance in contact with a gas mixture can be considered negligible. However, it is necessary to reduce the temperature of combustion products in the case of thermally unstable liquids. To reduce the temperature of combustion products effectively using gazokontrolja head to getgenerator device.
