What temperature will start a fire?
For traditional flames, the minimum temperature is usually around 1100-1200K, which is the the temperature where chain reactions that favor combustion start to dominate. Cool flames are an interesting phenomenon where flames may be sustained at temperatures as low as 400C.
Can a fire start without a spark?
