Difference:
Fire Flame |
Fire is a chemical reaction (combustion)
Flame is part of flaming combustion and only occurs during the ignition phase |
|
|
Flaming Combustion
|
Gas Fuels
Oxygen travels to the reaction zone |
|
|
Non-flaming Combustion
|
Solid Fuels
Supported by Oxygen that travels to the surface Reaction Zone traves to the Oxygen |
|
|
The Flame Bag is filled with...
Chemical Reactions occur... |
Fuel gases
At the edge of the Flame Bag, where it contacts with Oxygen in the air |
|
|
Pyrolysis
|
Heat Divided
|
|
|
Heat breaks... (2)
|
Fuel into smaller and smaller fragments
Long carbon chains into smaller and smaller chains |
|
|
Smoke
Soot |
Carbon-dioxide, Water, Tar, Soot
Unburned Carbon Chains |
|
|
Scorch or Char
|
To divide the solid fuel through heat, but not ignite it
|
|
|
Pre-Ignition Phase
|
pilot heat dries the fuel by evaporating the moisture
Makes Fuel Bag |
|
|
Ignition Phase
|
Pilot heat ignites fuel
Flaming Combustion |
|
|
Combustion Phase
|
Flaming, then Non-flaming (Glowing or Smoldering). Reaction Zone travels to fuel. Heat pyrolyzes, then pyrolyzed fuel combusts.
Leaves little or no soot. Smoke is now mostly Water and Carbon Dioxide. Mineral ash left over. |
|
|
Convection Column
|
More air increases reaction
More heat increases flow of Winds can add Oxygen therefore increasing the fires size and intensity. Be able to draw a picture |
