Explosion safety in gas transferring systems without using external control

摘要

Flame arresters used in industry at present localize burning without extinguishing it. To stop burning the flow of combustible mixture has to be cut off. A new approach is proposed to extinguish flame without interrupting the flow based on use of catalytically active material as a flame arrester packing (Tyulpinov A.D., Glikin M.A. Elimination of emissions into atmosphere and equipment shutdown during inflammation of combustible gaseous and powder/gas fluids. The 9-th International Symposium on Loss Prevention and Safety Promotion in the Process Industries, Barcelona, May 4-7, 1998). Investigations in this area found out the presence of a high-temperature zone of catalytical oxidation of combustible components. The influence of gas flow rate through the bed on stability of the high-temperature zone position and its velocity in longitudal direction has been studied. The data obtained were used to develop a novel method of explosion protection in operation of gas transferring systems.
