Abstract:
Deflagration suppression and explosion isolation apparatus comprising:structure for confining flowable, combustible material which presents a fire and explosion hazard; an elongated conduit communicating with the structure for normally conveying material from the structure to a defined area remote from the structure, said conduit being of a length and configuration longitudinally thereof that upon unforseen ignition of the material in the structure, flame can course along the conduit toward the defined area in the form of a deflagration front that transitions into a detonation state before reaching the defined area; a suppressant device communicating with the conduit in disposition to direct a suppressant agent into the conduit; a pressure detector associated with the structure and said conduit and operable to sense a rise in pressure resulting from ignition of the material in the structure and to activate the suppressant device to deliver suppressant agent into the conduit, said suppressant unit being located on the conduit along the length thereof in disposition to inject suppressant agent into the conduit at a point before the flame can reach the point of suppressant injection; and an isolation assembly connected to the conduit ahead of the protected area is operable in association with the suppressant device to activate a physical barrier to prevent flame and pressure from entering.
