PLANT BIOMASS SOLID FUEL
First Claim
1. A solid fuel material for combustion comprising:
- a series of body pieces each formed of compressed materials extruded through a die such that each body piece has a peripheral, longitudinally extending, outer surface with each body piece being severed from next adjacent body pieces to form two surfaces transverse to the peripheral surface;
each body piece having a density greater than 35 lbs/cu ft;
each body piece having an energy content greater than 6500 BTU/lb;
each body piece having dimensions in the transverse direction which are all less than 1.5 inches;
substantially all the body pieces having a length in the longitudinal direction between the transverse surfaces which is less than 4 inches;
wherein the compressed materials comprise plant biomass materials;
wherein the plant biomass material contains at least some components which have a dimension when extended of greater than 1.0 inch.

Abstract
A solid fuel is formed in a cuber to form body pieces formed of materials extruded through a die with a density greater than 35 lbs/cu ft; an energy content greater than 6500 BTU/lb; transverse dimensions less than 1.5 inches; and a length less than 4 inches; from plant biomass material which contains components when extended of greater than 1.0 inch. Primarily the materials are paper or other cellulose product and crop residue such as wheat straw. The cellulose and lignin from these materials act without additional binders as binders and encasing materials. The moisture content is maintained at a target value by mixing selected quantities of the materials without drying. The cubing machine has a feeding system where the space between the inner rotor and outer casing is smaller than 4 inches and the height of the outer flight is less than 1 inch.
