ABSTRACT:
A system for sensing and acting to suppress flame conditions as well as an explosion associated with a flame front in an enclosure which is susceptible to fire and explosion condition, such as trash shredders, grain elevators, and enclosed areas where oxygen and combustible material may be present in the necessary proportions to feed a fire of such rapid propagation as to result in explosive proportions resulting in damage to the structure forming the enclosure. The system comprises means distributed about the enclosing structure to sense a flame as well as a sudden rise in pressure and set off a fire and explosion suppressing system which operates to flood the enclosed area with an agent capable of quenching the flame causing the pressure rise, and programmable monitoring control circuits for operating the system and all of its components during the time when a pressure rise signals the development of an explosion, and following the suppression of an explosion.
