Key factor in determining the speed at which matter is combusted

As we know oxygen is a key factor in determining the speed at which matter is combusted. When the supply of oxygen is in unlimited, the rate at which matter is combusted is high resulting in production of large volumes of heat and combustion of all matter. A slow combusting fire’s start point is exhibited by homogenous wall and ceiling destruction. Surfaces such as wood or painted surfaces show a baked picture and there is progressive charring and stains of smoke on doors, windows and window glasses. A fast combusting fire’s start point exhibits extensive overhead destruction with defined combustion patterns on walls and pronounced charring on wood especially the parts that come in direct contact with the flame. A discrete line close to the start point of the fire separates the charred and uncharred areas. There is also a distinct line between the burned and unburned regions on doors and windows.
