THE DEVELOPMENT OF THE AUTOMATIC FIRE EXTINGUISHING UNIT WITH USE OF GAS-GENERATING DEVICES FOR PROTECTION OF TECHNICAL OBJECTS OF SMALL VOLUMES

The variations of temperature of the object gas medium and oxygen concentration in it after operation of the automatic fire extinguishing unit have been studied. The purpose of the work: the development of the automatic nitrogen fire-extinguishing unit fro protection of the command stations of the tactic level, to be located in the bodies-containers of the transport vehicles. The analytic dependences of the temperature variation and the oxygen concentration in the gas medium of the object (of the body-container type) have been obtained after the fire extinguishing with nitrogen. Determined have been the basic factors, influencing on the variation of the initially created concentration composition of the gas medium. The methodical approach to creation of the fire extinguishing units with application of the nitrogen generators has been developed. Introduced in practice have been the department building norms VSN 163-91 "Technical Rules of the Work Production on Mounting, Adjustment and Acceptance in Operation of the Automatic Fire-Extinguishing Units"Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
