What is a smoldering fire?
Compared to flaming fires, smoldering is considered a type of low-intensity fire (Rein, 2016), meaning that fire slowly spreads and can be expected to last for several days, releasing small amounts of energy (Keeley, 2009).
Which one is smoldering stage of fire?
The smouldering stage is a region of fully developed pyrolysis that begins with ignition and includes the initial stage of combustion. Invisible aerosol and visible smoke particles are generated and transported away from the source by moderate convection patterns and background air movement.
What is a flaming combustion?
Flaming combustion is the most common type of combustion. It is the open-flame fire, such as the one seen in a gas burner. Chemically, it is a gas-to-gas reaction, meaning that the fuel has to be in the gaseous state in order to react with the oxidizer, which is already in the gaseous state.
How does smouldering combustion differ from flaming combustion?
The fundamental difference between smouldering and flaming combustion is that smouldering occurs on the surface of the solid rather than in the gas phase. Smouldering emits toxic gases (e.g., carbon monoxide) at a higher yield than flaming fires and leaves behind a significant amount of solid residue.
What is smouldering intensity?
A “smoldering intensity” is like the heat from smoldering fire – you can’t see any flame, but the heat can be intense (very strong).
