Gasifiers

A definition of gasification and gasifiers:

When dry biomass fuel such as wood is burned in any fire, the solid fuel must first be converted into its component combustible gases.  When the making of those gases is separate from where the gases are combusted, the device is called a “gasifier” and the process is “gasification.”  Be prepared for multiple definitions and explanations of gasification and gasifiers.  There are several main types of gasifiers, and many overlapping technologies.  For an in-depth study, you should visit gasifiers.bioenergylists.org for many hours.  What is presented here is brief about the larger gasifiers, and quite detailed for the specifics of micro-gasification.  Large-system gasification has been in use for nearly two centuries, but the two forms of very small scale gasification (called “micro-gasification”) were not practical and commercially available until 2003 and 2006.
