ABSTRACT:
A tilted, fixed kiln with rotory steam gasifier having a fixed elongated, pressurizable kiln body member with an input end and an output end and with the center axis supported at an angle to the horizontal so as to bring into effect gravitational forces acting on high moisture content biomass material fed into the input end and travelling through the kiln to the output end and having in the kiln body an axially extending rotor and a motor, radially spaced-apart scoop-like blade elements extending along the axial length of the kiln for tumbling the material, means for increasing the temperature from its input to its output end, spaced-apart blades and chains disposed in the rotor kiln cavities for stirring the biomass material as it travels through the kiln to prevent agglomeration, a plurality of parallel, axially extending hot gas counter-flow feedback pipes arranged around the kiln body and along the backsides of the scoop-like blade elements, a metering auger mounted vertically to the input end of the kiln to assure continuous flow of the biomass into the kiln, and dam-like baffles mounted within the kiln body to increase the volume held in the kiln.
