Stages of Wood Combustion
Stage 1: The Evaporation of Moisture Anyone who has ever tried to burn wet or unseasoned wood will find this stage very frustrating. During the moisture evaporation stage, instead of producing heat, heat is absorbed. Water trapped inside of the wood is turned into steam and removed from the wood. Once this process is complete, it leads to Stage 2. Stage 2: The Vaporization of Hydrocarbon Compounds Stage 2 we still are not into the heat producing phase (maybe a tiny bit) but we are close! At this point, we are over five hundred degrees and temperatures are on the rise. The chemical structure of the wood starts to break down and the process of pyrolysis begins. Pyrolysis “liberates organic gases and leaves carbon rich charcoal”. This process also creates a mixture of hydrocarbons in the form of liquid tar droplets and combustibles gases, and digging in is very complex. … Continued
