kerosene has got higher ignition temperature.

Wood needs to reach its ignition temperature to catch fire. When heated only slightly, the temperature may not be high enough to cause ignition. Additionally, a lack of sufficient oxygen or fuel can also prevent wood from catching fire when heated a little.
The ignition temperature is about 250 Celsius for ordinary wood.
For Burning wood:The temperature for the piloted ignition of wood is typically about 350 °C (660 °F), whereas the spontaneous ignition requires a temperature of approximately 600 °C (1100 °F)http://virtual.vtt.fi/virtual/innofirewood/stateoftheart/database/burning/burning.html
The minimum temperature the fuel ignites self sustained combustion is known as spontaneous ignition temperature. The temperature at which the substance is preheated and burns smoothly is known as ignition temperature.
No, although the answer does depend on the temperature scale being used.Most materials have a temperature, the autoignition point, at which they will spontaneously ignite without the need of an external source of ignition. For wood this is around 300 deg C although the exact value will vary from one species to another. At this temperature cellulose, which is present in all wood, starts to disintegrate and releases hydrocarbons. These react with the oxygen in the air and cause ignition.
If the ignition temperature is lower than the room temperature, the substance will not ignite or burn spontaneously at room temperature. Ignition temperature refers to the minimum temperature required for a substance to ignite and sustain combustion, so if it is lower than the room temperature, the substance will remain stable at that temperature.
Yes, wood does have a fire point, which is the temperature at which it will ignite and sustain burning without the need for an external flame. This temperature is typically around 572°F (300°C) for most types of wood.
Varnished wood can catch fire at temperatures above 400 degrees Fahrenheit. The ignition point can vary depending on the type of varnish and other factors like the thickness of the wood. It's important to handle varnished wood safely to prevent fire hazards.
