Screw Auger Chippers
The problem of fuel wood preparation for gasification projects is a universal problem and the easiest option is to use chipped wood. Many projects using chipped wood have failed even though the gasification equipment is considered "state of the art".
Chippers using rotary bladed drums or rotating plates with blades produce a fine chip, perfect for combustion but not suitable for gasification. In gasification the fine chip breaks down too quickly and fills the interstitial space between the particles preventing inflow of air and the outflow of gas.
Screw auger chippers provide the best chip size option and this brochure shows an ideal size for most gasifier projects.
