Abstract

A gasifier for disposing of biomass and other waste materials through a gasification and combustion process. The gasifier includes a primary chamber for receiving and holding biomass or a selected waste product. A heat transfer chamber is disposed adjacent the primary chamber. A burner is associated with the gasifier for generating heat and heating the gasifier during various phases or portions of the gasification and combustion process. In the gasification process, the heat transfer chamber is heated and the heat is transferred to the primary chamber where the biomass is heated. During the gasification process, biomass material is volatized generating fumes and gases that later react and release heat through exothermic reactions. Once the gasification process has been concluded, the process enters a combustion phase where the biomass is actually burned. During the gasification-combustion phases, the amount of heat supplied by the burner will vary. Generally the amount of energy or heat supplied by the burner will decrease throughout the process because the biomass itself will supply substantial amounts of heat through exothermic reactions.
