  1. The New Revolution in Fire Suppression Technology International Aircraft Systems Fire Protection Working Group Atlantic City NJ. 29 Aug 2000

  2. Introduction Contents 1 Evolution of Pyrogen 2 Technical Characteristics 3 Performance and Benefits 4 Typical Applications & Installations 5 Comparison with Other Gases

  3. Evolution What is Pyrogen? Pyrotechnically Generated Aerosol Fire Extinguishing System

  4. Evolution: The Secret to Pyrogen’s Power • Unique formulation of • solid aerosol generating composition ~ derivative of solid rocket fuel • solid chemical coolant ~ ensures flameless operation & rapid expulsion • Produces gas-like fire fighting aerosol with 3 dimensional distribution when ignited

  5. Technical Characteristics: Four Main Elements Directional Plate Chemical Coolant Solid Block of Aerosol Generating Composition Electric Ignition Device

  6. Technical Characteristics: Multiple Activation for Ignition • Electrical • Automatic via detection system or, • Manual via manual release point • Thermal • Automatic via temperature sensitive pyrotechnic cord 175 C (347 F)

  7. Technical Characteristics: PRODUCT DESCRIPTION: Aerosol Generation Ignition of aerosol-forming composition = solid potassium carbonates + carbon dioxide gas + nitrogen gas + water vapor KNO3(s) + CnHmNpOq(s) + C(s) = KHCO3(s) + K2CO3(s) + CO2(g) + N2(g) + H2O(g)

  8. Technical Characteristics: Chemical Coolant • Polymer composition highly impregnated with endothermic ingredients • Substances that decomposes at 200-300°C (392-572F) without melting, generating gases and absorbing approximately 400 calories of heat per one kilogram of their mass. • Cooling is effected at a fantastic rate of 400° per second

  9. Technical Characteristics: BENEFITS: Micron Size Aerosol Particles • Large surface area for extinguishing actions • Small amount required for reliable extinguishing • Gas-like 3 dimensional distribution • Long suspension times

  10. How It Works: 3 Potential Methods of Actuation Fire Conducting Cord Heated >175°C Electrical Signal from Control Panel (Manual / Automatic) Naked Flame via Fire Conducting Cord

  11. How It Works: Chemical coolant decomposes absorbing heat Fire fighting aerosol rapidly generated Aerosol Generated

  12. How It Works: Decomposed chemical coolant Aerosol Discharged Total flooding aerosol demonstrates 3D gas-like properties. Holding times up to 60 minutes.

  13. Basics: O2 O2 O2 Oxygen Heat Fuel Fuel BENEFITS: The Three Elements of Fire Heat

  14. Basics: O2 O2 O2 Oxygen Chain Carriers O, H & OH Heat Fuel Fuel BENEFITS: The Fourth Element of Fire O H OH Heat

  15. How It Works: Extinguishing Actions • Dual Extinguishing Actions • Primary: • Chemical - Removal of chain carriers • Secondary: • Physical - Heat absorption

  16. How It Works: BENEFITS: Dual Extinguishing Actions • Chemical - removal of chain carriers OH, H and O • in gaseous phase: • K + OH = KOH • K + O = KO • KOH + H = K + H2O • on particles surface: • O + H = OH • H + OH = H2O • Physical - heat absorption • KHCO3 = K2CO3 + CO2+ H2O • K2CO3(s) = K2CO3(g)

  17. How It Works: BENEFITS: Extinguishing Actions • Two Chemical Mechanisms • Removal of flame propagation radicals - chain carriers OH, H and O in the flame chain K + OH = KOH KOH + H = K + H2O • Recombination of flame propagation radicals - chain carriers OH, H and O aerosol on particles surface: O + H = OH H + OH = H2O

  18. How It Works: BENEFITS: Extinguishing Actions • Physical - Lowering the fire temperature to a level below which the fire reaction cannot continue thermal cooling • Heat absorption via endothermic phase changes K2CO3(s) = K2CO3(l) = K2CO3(g) • Heat absorption via endothermic decomposition changes 2KHCO3(s) = K2CO3(S) + CO2(G) + H2O(g)

  19. How It Works: BENEFITS: Extinguishing Actions • Physical - Lowering the fire temperature to a level below which the fire reaction cannot continue thermal cooling • Dilution of the fire combustion zone by the aerosol cloud (additional fuel molecules cannot participate in the combustion process) • Physical hindrance to flame propagation (aerosol particles slow down velocity of a flame front propagation)
