![]() Ignition and combustion of wood is mainly based on the pyrolysis (i.e. Under the influence of heat, wood produces easily substances that react eagerly with oxygen, leading to the high propensity of wood to ignite and burn. Many materials in our environment, including wood products, burn “indirectly” in the sense that the materials do not actually burn, but combustion takes place as a reaction between oxygen and the gases released from a material (an exception from this rule is the glowing combustion of charred wood where oxygen reacts directly with carbon). transfer of oxygen into reaction areas.įollowing topics are covered in this section:.physical and chemical processes of compounds produced in these changes, both inside the wood and in the gases formed above it.heat induced changes of the internal structure of wood in molecular level.The reduction of ignitability and combustibility of wood products is based on chemical and physical means that have an effect on different stages of ignition and burning, for example: ![]()
