Fire suppression systems

摘要

A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.

1. A method of fire suppression, comprising:
providing a structure having a volume, a source of fuel, an air intake, and an outlet, wherein an air flow path is defined through the structure between the air intake and the outlet and wherein the structure defines a flame holding region capable of sustaining a spatially stable flame in the presence of an oxidizer and a fuel and a flow of at least one of an oxidizer and a fuel to the flame holding region; providing a supply of a reactive agent; injecting the reactive agent into a reaction zone in the volume at which the reactive agent reacts to produce a chemical species that catalytically interferes with flame chemistry; and conveying the catalytic chemical species from the reaction zone to said flame holding region by the flow.
