Q:

How hot is fire?

A:

Wood fires usually burn at a temperature of around 1,950 degrees Celsius. The exact temperature of the flame is dependent on external conditions such as the type of fuel being burned, available ventilation and the form of oxygen available for combustion.

The hottest flame ever produced artificially burned at a recorded 4,990 degrees Celsius. It was accomplished with dicyanoacetelyne as a fuel and an ozone atmosphere. Flames as cool as 120 degrees Celsius have been produced using precisely regulated fuel-air mixtures. This "cool fire" is only 20 degrees hotter than the boiling point of water, so the reaction has trouble maintaining combustion temperature and tends to go out quickly.

  • Q:

    At what temperature does wood catch fire?

    A:

    Dry wood catches fire between about 300 degrees Fahrenheit and 580 degrees Fahrenheit, depending upon the species of wood and the extent of decay present, with more decayed wood being quicker to ignite. The amount of moisture in the wood is the strongest influence on wood reaching this temperature.

  • Q:

    At what temperature does charcoal burn?

    A:

    Burning charcoal can produce temperatures above 1,000 degrees Fahrenheit. With a grill, the type of charcoal and grill used determines the optimal burning temperature. A kettle grill fully loaded with red-hot charcoal can produce up to 700 degrees Fahrenheit. Others can produce temperatures as low as 200 degrees Fahrenheit.

  • Q:

    At what temperature does wood start to burn?

    A:

    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.

  • Q:

    At what temperature does gasoline burn?

    A:

    Gasoline burns at 495 degrees Fahrenheit at standard atmospheric pressure. This ignition temperature is the lowest temperature at which gasoline may undergo combustion. If the temperature is lower than this, a fire is needed to ignite gasoline. If too little air is present, a higher temperature is needed.
