ABSTRACT:
A wood gasification apparatus in which cellulosic material is transported by an auger through a housing and heated to vaporize at least a portion of the cellulosic material by frictional heating. The auger and housing define a spiral void through which the cellulosic material is propelled from the inlet to the outlet, and which continually decreases in volume from the inlet to the outlet. The ever decreasing volume of the void increases the pressure on the cellulosic material and maximizes the frictional heating until the material reaches a vaporization temperature.
