The process of burning off a stump includes using a chainsaw for cutting and a fire for charring wood. The process is completed by the use of oxygen and the right amount of heat.
In order to burn out the stump, it needs to be cut into small pieces with a chainsaw. The stump will then be placed on top of the fire that needs to be lit. The heat from the fire will cause oxidation in air around it which will then cause combustion in wood and create heat that is necessary for burning out stumps
The process can also be completed by using an oxy-fuel torch as well as creating ash and embers with enough heat that they can ignite wooden logs.
