Ignition Temperature Of Wood

Department of Agriculture studies on wood ignition conclude that there is not a fixed temperature for ignition and the moment of ignition largely depends on the amount of exposure time the density of the wood and the type of wood.

Ignition temperature of wood. Babrauskas concluded in his analysis that the short term ignition temperature of wood is around 482oF. A previous investigation by RE. 400-500 wood chars at a rate of approximately 30-50 mmhour.

Decayed wood ignites at a temperature of 150 C. Prince 7 demonstrated clearly that what he termed the ignition temperaturefor wood does not have a fixed value but is greatly influenced by the duration of exposureIn that work oven-dry wood specimens 1-14 by 1-14 by 4 inches were exposed continuously to different temperatures maintained constant in an electrically heated apparatus. Wood solids starts to break down converting the fuel gases near 575 o F 300 o C.

As a result the published ignition temperatures of wood will vary widely. Ignition Temperature of Wood Wood placed in an oven at 700F. Wood heats up to approximately 212 o F 100 o C evaporating the moisture in it.

Atreya found that the measured surface temperature at ignition for horizontal and vertical samples ofmahogany lay between 350 and ca. Auto Ignition Temperature The Auto-Ignition Temperature - or the minimum temperature required to ignite a gas or vapor in air without a spark or flame being present - are indicated for some common fuels below. 3900C in the range of irradiances 18 -50 kWm2.

1b for piloted ignition. This temperature is required to supply the activation energy needed for combustionThe temperature at which a chemical ignites decreases as the pressure or oxygen concentration increases. 218-246 Oil soaked lagging ignites.

Temperature Celsius Wood slowly chars 120-150 Decayed wood ignites. Note that there is one value lying outside the range. 25304 MJcord 17055 kgcord 148 MJkg The Combustion Process of Burning Wood.
