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

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

4
From Rocket Fuel to Revolutionary Fire
Extinguisher
Evolution
  • Highly effective fire suppression system
    Advanced product of Russian space technology
  • Conversion of military research into civil
    applications

5
The Secret to Pyrogens Power
Evolution
  • 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

6
Four Main Elements
Technical Characteristics
Directional Plate
Chemical Coolant
Solid Block of Aerosol Generating Composition
Electric Ignition Device
7
Multiple Activation for Ignition
Technical Characteristics
  • Electrical
  • Automatic via detection system or,
  • Manual via manual release point
  • Thermal
  • Automatic via temperature sensitive pyrotechnic
    cord 175 C (347 F)

8
Aerosol Generation
PRODUCT DESCRIPTION
Technical Characteristics
  • 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)

9
Chemical Coolant
Technical Characteristics
  • Polymer composition highly impregnated with
    endothermic ingredients
  • Substances that decomposes at 200-300C
    (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

10
Micron Size Aerosol Particles
Technical Characteristics
BENEFITS
  • Large surface area for extinguishing actions
  • Small amount required for reliable extinguishing
  • Gas-like 3 dimensional distribution
  • Long suspension times

3 Potential Methods of Actuation
How It Works
Fire Conducting Cord Heated gt175C
Electrical Signal from Control Panel (Manual /
Automatic)
Naked Flame via Fire Conducting Cord

17
Extinguishing Actions
How It Works
  • Dual Extinguishing Actions
  • Primary
  • Chemical - Removal of chain carriers
  • Secondary
  • Physical - Heat absorption

18
Dual Extinguishing Actions
How It Works
BENEFITS
  • 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)

19
Extinguishing Actions
How It Works
BENEFITS
  • 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

20
Extinguishing Actions
How It Works
BENEFITS
  • 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)

21
Extinguishing Actions
How It Works
BENEFITS
  • 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)
