Small fires are used in several ways to control large fires.
First, prescribed fires can be used as a technique to reduce forest fuel loads during periods of low forest fire risk. If wildfires later occur, they will not be as intense and may not be able to spread beyond natural or man-made boundaries.
During fire suppression, one of the primary techniques is to make a "fuel separation" between burning fuel and the rest of the world. This is generally accomplished by "containing" the fire in a fireline, using hand tools, bulldozers, retardant bombers, or other means.
However, these often leave large unburned areas between the main fire and the fireline, creating a risk that the main fire could burn with enough intensity to "jump the line" and continue. A "backfire" is used under certain circumstances to ignite fuels along the inside of the fireline, while they can be controlled, making a "black area" with very little forest fuel to burn when the main fire arrives.
The other use of small fires in suppression is to "burn out" small unburned areas within the main fire, so that they do not later rekindle and create enough heat to spread to other unburned fuels.
