What are some qualities of a smoldering fire?
Smoldering is a slow, low temperature, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed phase fuel. It constitutes a serious fire hazard fortwo reasons.
Why do fires smolder?
Slow-starting smoldering fires most often occur when smoking materials, such as cigarettes, are left unattended. These fires produce a large amount of thick smoke, which can contain toxic chemicals like carbon monoxide and cyanide.
How are fires described?
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.

What is a smoldering fire?
Smoldering is characteristically an incomplete combustion, and it releases species and quantities that substantially depart from that in stoichiometric and complete combustion. Smoldering fires are rare events at the local scale but occur regularly at a global scale.
What is smouldering?
Smouldering ( British English) or smoldering ( American English; see spelling differences) is the slow, flameless form of combustion, sustained by the heat evolved when oxygen directly attacks the surface of a condensed-phase fuel.
What is the difference between smouldering and combustion?
Smouldering is a surface phenomenon but can propagate to the interior of a porous fuel if it is permeable to flow. The characteristic temperature and heat released during smouldering are low compared to those in the flaming combustion.
What is the speed of smouldering?
Smouldering propagates in a creeping fashion, around 0.1 mm/s (0.0039 in/s), which is about ten times slower than flames spread over a solid. In spite of its weak combustion characteristics, smouldering is a significant fire hazard.
