Claim:
A gasification system for gasifying one or more materials, comprising: a gasification chamber capable of gasifying the one or more materials to produce one or more products; at least one moveable agitator arm located within the gasification chamber for fluidizing the one or more materials during gasification, the agitator arm moveable arcuately through the gasification chamber and wherein the agitator arm comprises a circular cross-section; and a plurality of discrete, planar, angled blades spaced radially along the at least one agitator arm wherein each blade circumscribes the at least one agitator arm and comprises a circular cut-out portion at which the blade connects to the at least one agitator arm, wherein the circular cut-out portion is formed in such a way as to allow disposition of the blade at an angle with respect to a central axis through the at least one agitator arm, and wherein each blade other than that one of said blades positioned most radially outward is spaced with respect to a next-adjacent radially outward blade on each agitator arm at such distance that ash within the gasification chamber may be pushed from a position radially aligned with such blade to a position radially aligned with such next-adjacent radially outward blade.
