Abstract
A method and apparatus for suppressing a fire utilizing non-azide solid gas propellant generation to produce and transport a suitable gas for suppressin g a fire in a normally occupied area. The nitrogen gas produced by the solid propellant gas genreation is optionally treated to remove undesirable elemen ts such as water and/or carbon dioxide from the product gas prior to the delive ry of the product gas to the protected hazard area.
Claims (18)
1. A method of suppressing fires in a space comprising the steps of:
(a) generating a first oxygen displacing fire suppressing gas mixture from at least one non-azide solid propellant chemical, the first fire suppressing gas mixture comprising at least a first gas, said first gas comprising nitrogen;
and (b) delivering at least said first gas into the space, wherein said oxygen displacing fire suppressing gas mixture reduces the concentration of oxygen in said space to below a level necessary to sustain combustion.
(a) generating a first oxygen displacing fire suppressing gas mixture from at least one non-azide solid propellant chemical, the first fire suppressing gas mixture comprising at least a first gas, said first gas comprising nitrogen;
and (b) delivering at least said first gas into the space, wherein said oxygen displacing fire suppressing gas mixture reduces the concentration of oxygen in said space to below a level necessary to sustain combustion.
2. The method as claimed in claim 1 further comprising the step of filtering at lease a percentage of a second gas from the first fire suppressing gas mixture prior to delivery into the space.
3. The method as claimed in claim 2 wherein the second gas comprises water vapor.
4. The method as claimed in claim 3 wherein the second gas comprises CO2
5. The method as claimed in claim 2 wherein substantially all of the second gas is filtered. from the first fire suppressing gas mixture.
6. The method as claimed in claim 1 further comprising the step of reducing the temperature of the second fire suppressing gas mixture.
7. An apparatus for suppressing fires in a normally occupied enclosed space comprising:
(a) a sensor for detecting a fire;
(b) at least one non-azide solid inert gas generator that, in response to receiving a signal from the sensor, ignites to generate only an oxygen displacing fire suppressing gas mixture for delivery into the enclosed space; and (c) an inert gas discharge diffuser to direct the fire suppressing gas mixture iota said enclosed space for reducing the concentration of oxygen in said space to below a- level necessary to sustain combustion.
(a) a sensor for detecting a fire;
(b) at least one non-azide solid inert gas generator that, in response to receiving a signal from the sensor, ignites to generate only an oxygen displacing fire suppressing gas mixture for delivery into the enclosed space; and (c) an inert gas discharge diffuser to direct the fire suppressing gas mixture iota said enclosed space for reducing the concentration of oxygen in said space to below a- level necessary to sustain combustion.
8. The apparatus as claimed in claim 7 wherein the fire suppressing gas mixture includes nitrogen.
9. The apparatus as claimed in claim 8 wherein the fire suppressing gas mixture includes at least one of water vapor and carbon dioxide.
10. The apparatus as claimed in claim 7 wherein the fire suppressing gas mixture comprises at least two gases and the apparatus further comprises at least one filter for filtering at least a portion of at least one of the gases from the fire suppression gas mixture, prior to the delivery thereof to the enclosed space.
11. The apparatus as claimed in claim 10 wherein the filter is adapted to filler substantially all of the at least one of the gases from the first suppressing gas mixture.
12. A gas generator for generating mid delivering an oxygen displacing fire suppressing gas mixture to an enclosed space, comprising:
a housing;
at least one pre-packed non-azide solid propellant disposed within said housing;
a pyrotechnic device for initiating ignition of road solid propellant to thereby generate only said fire suppressing gas mixture; and a discharge diffuser for directing the fire suppressing gas mixture within said enclosed. space so as to reduce the concentration of oxygen in said space to below a level necessary to sustain combustion.
a housing;
at least one pre-packed non-azide solid propellant disposed within said housing;
a pyrotechnic device for initiating ignition of road solid propellant to thereby generate only said fire suppressing gas mixture; and a discharge diffuser for directing the fire suppressing gas mixture within said enclosed. space so as to reduce the concentration of oxygen in said space to below a level necessary to sustain combustion.
13. The gas generator as claimed in claim 12, further comprising at least one filter for filtering at least a portion of one gas from said f re suppressing has mixture.
14. The gas generator as claimed in claim 12, further comprising at least one screen for reducing the temperature of said fire suppressing gas mixture.
15. The gas generator as claimed in claim 12, wherein said discharge diffuser includes a 180° directional cap.
16. The gas generator as claimed in claim 12, wherein said discharge diffuser includes a 360° directional cap.
17. The gas generator as claimed in claim 12, wherein said discharge diffuser includes a perforated cap.
18. The gas generator as claimed in claim 12, wherein said discharge diffuser includes a 90° directional cap.
