Record 4 2010-09-23

English

Subject field(s)
  • Chemical Engineering
  • Biomass Energy
CONT

Pyrolytic Reactions and Products of Biomass.... Presence of air increases the rate of decomposition and pyrolysis by oxidation of the substrate at the lower temperatures. At the higher temperatures oxidation of the volatile pyrolysis products results in flaming combustion and oxidation of the char leads to smoldering or incandescence combustion according to the rate of reaction. Presence of water and steam is also known to speed up the breakdown and degradation of the molecules by hydrolysis of the substrate and rearrangement of the intermediate products. This process, known as hydrothermolysis, may be catalyzed by acids or alkali reagents as discussed later. At higher temperatures the steam plays a more direct and better known role as a reactant in the gasification of char and related processes. At the higher temperatures, CO2 and H2 could also function as reactants.

Record 6 2005-04-13

English

Subject field(s)
  • Combustion and Fuels (Fireplaces)
  • Brush, Prairie and Forest Fires
DEF

Luminous oxidation of gases evolved from the rapid decomposition of fuel.

OBS

This phase follows the pre-ignition phase and precedes the smoldering combustion phase, which has a much slower combustion rate.

French

Domaine(s)
  • Combustion et combustibles (Foyers)
  • Incendies de végétation
DEF

Phénomène d'oxydation lumineuse des gaz et résultant de la décomposition accélérée de la couche de combustible.

Record 7 2002-04-29

English

Subject field(s)
  • Research Experiments in Space
CONT

The objective of this experiment is to study the effects of oxidizer, flow rate, pressure, and orientation, on the ignition and propagation of smoldering combustion. It includes experiments in normal gravity and in microgravity-the latter are being conducted in the Space Shuttle. This research will improve our ability to predict and prevent smolder-orginated fires on Earth and in space.

Record 8 2001-03-16

English

Subject field(s)
  • Fires and Explosions
  • Brush, Prairie and Forest Fires
DEF

The stage of burning in which the oxidation of solid fuel is accompanied by incandescence.

CONT

In the glowing phase, all volatile materials have already been driven off and there is no visible smoke; this phase follows the smoldering combustion phase and continues until the temperature drops below the combustion threshold value, or until only noncombustible ash remains.

French

Domaine(s)
  • Feux et explosions
  • Incendies de végétation
OBS

combustion couvante : Combustion lente d'un matériau sans émission de lumière visible et généralement mise en évidence par une augmentation de la température et/ou un dégagement de fumée.

OBS

incandescence : combustion en phase solide.

Subject field(s)
  • Combustion and Fuels (Fireplaces)
  • Welding and Soldering (Metals)
DEF

The confines (not necessarily visible) of the combustion process (converting fuel and air into products of combustion).

CONT

smoldering phase : a phase of combustion that can occur after flames die down because the reaction rate of the fire is not high enough to maintain a persistent flame envelope.
