Ignition Temperatures of Various Common Materials The following data demonstrates that the chemical mixtures found in fireworks are less prone to ignite if heated than are many common materials found in retail stores, warehouses, and homes.

The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a 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.
The minimum temperature needed for self-sustained combustion in absence of a spark or flame, at which the vapours from a volatile liquid will ignite spontaneously. The autoignition temperature (AT) is of interest to the Occupational Safety and Health Administration (OSHA) (US), which lists ATs in its Materials Safety Data Sheets, see there.
In order to get the most heat from your firewood, the moisture content should be 20% or less. Freshly cut firewood or "green" firewood has a moisture content of 50% or more depending on the species. So as you can see, properly stacking firewood and allowing air drying must occur before it is burned in a wood stove.
Wood usually ignites at 250 – 300 C. After ignition, the wood begins to carbonise at a rate of 0.8 mm per minute. Fire progresses slowly in a solid wood product, as the layer of carbon created protects the wood, and slows down the increase in temperature of the wood’s inner parts and thus the progress of the fire.
Cedar kindling is arguably the best kindling available. Why is it so good? Cedar is very porous and it contains natural oils within the wood that burn hot and fast. Cedar lights quickly and easily producing a hot fire, so it's perfect for starting a morning fire in your wood stove because it reduces the possibly of a slow burning, smoldering fire.
of determining the minimum ignition temperature of dust cloud from wood pellets are given in Tab. 4 and Tab. 5. and on Fig. 6 is the time-history of ignition of dust cloud. Fig. 6 Ignition time-history of dust clouds when tested according to EN 50281-2-1:2002
Interesting question. I’m not sure, but I can take an educated guess. The flame you see is of course the burning of vapour in air. The vapour that you see when wood or paper burn is produced by the heat of the flame itself (or that of the match yo...
The author appears to have used paper made with rayon or cotton, which could have a different auto-ignition temperature from pure wood pulp paper, but 450 degrees Celsius still sounds wrong.
The ignition temperature of bamboo from IM is in the range of 241–265 °C, which is located at the normal ignition temperatures of biomass, as shown in Table 1. On account of the increase in the temperature of the first major peak with increasing heating rate, it is not surprising that the ignition temperature goes up when the heating rate rises.
