Final answer:
Flaming combustion occurs when burning is localized on or near a fuel's surface. It is an exothermic process that releases heat energy.
Step-by-step explanation:
When burning is localized on or near a fuel's surface, it is referred to as flaming combustion. In flaming combustion, a visible flame is produced as a result of the reaction between the fuel and oxygen. This type of combustion is exothermic, meaning that it releases heat energy. The opposite of flaming combustion is nonflaming combustion, which occurs when there is insufficient oxygen or the fuel is not easily vaporized.
