Pyrolysis is the process of the vaporization or decomposition of organic materials, such as wood or biomass, due to high temperatures in the absence of oxygen.
It involves the thermal degradation of the material, resulting in the release of volatile gases, liquids, and char. Pyrolysis is a key process in the combustion of wood and other fuels, where the heat from the fire causes the organic material to undergo chemical changes, producing combustible gases and leaving behind charcoal or ash.
