kerosene has got higher ignition temperature.

The wood will not catch fire until it reached its combustion temperature. If at a lower temperature, the wood will simple smoulder, giving out smoke without a flame.
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
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.

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.
The coal dusts have large surface area thus it can easily absorb the heat and reach its ignition temperature and thus can burn easily... Remember a wood fillings can be easily burned in seconds but a wood block cannot be burnt easily as it takes time to transfer heat to all its body and thus reach the ignition temperature...
If the ignition temperature of a substance is lower than the room temperature where it is, then that substance ignites.
1100-1200 degrees Fahrenheit is the minimum ignition temperature.
