Heat & Combustion

The combustion of wood and other raw biomass is very complicated but can be broken down crudely into the steps.

“The solid is heated to about 100ºC and the absorbed water is boiled out of the wood or migrates along the wood grain to cooler areas and re-condenses. At slightly higher temperatures, water that is weakly bound to molecular groups is also given off. Heat transfer through the wood is primarily by convection.”
