When wood is completely dry and is not a type of artificial wood, the combustion temperature is generally 451 degrees Fahrenheit, according to the Argonne National Laboratory. However, there are many variables, such as moisture, oxygen ability and wood density, that come into play.
Firewood and combustion of wood heat values - for species like Pine, Elm, Hickory and more Sponsored Links Type of wood - whether it is hardwood or softwood - burned in the combustion process is important for the heat value and the energy efficiency.
The ignition point of wood varies depending on the type of wood and the dryness of the wood. Decayed wood ignites at a temperature of 150 C. As the surface temperature of the wood approaches 100 C, the water within the wood boils and then evaporates away, which makes the wood dry enough to ignite.
IGNITION AND CHARRING TEMPERATURES OF WOOD By Forest Products Laboratory, Forest Service U. S. Department of Agricultme 1-----A review of the technical literature reveals but a limited amount of data con-cerning minimum temperatures required to produce charring or ignition of wood.
The autoignition temperature or kindling point of a substance is the lowest temperature at which it spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.The temperature at which a chemical ignites decreases as the pressure or oxygen concentration increases.
In the study of combustion, there are two types of adiabatic flame temperature depending on how the process is completed: the constant volume and constant pressure; both of which describe temperature that combustion products theoretically can reach if no energy is lost to the outside environment. [clarification needed]The constant volume adiabatic flame temperature is the temperature that ...

Wood may be said to burn directly if its surface is irradiated so intensely that the temperature is raised to the point of spontaneous ignition within a fraction of a second,so that pyrolysis and combustion are practically simultaneous.
Now I have taken the temps of the wood with an IR gun at the rear corners where it gets hottest with the stove at max operating temps. These temps are usually around 110 - 131F. Is it true that the ignition point of wood is around 500F. While the walls feel quite warm they are not overly hot to the touch.
in that the temperature reached a plateau in the region 360 -3800C before rising further to the onset of sustained ignition at a higher temperature (average> 4000C). Visual observation ofthe samples at these lower heat fluxes indicated the onset ofglowing combustion at the surface well before flaming was initiated. Glowing was observed to start
