  • Patent number: 5980595
    Abstract: A fuel pellet and a method of manufacturing a fuel pellet capable of burning in either a stoker or pulver furnace, comprising from about 0 to about 80% by weight of cellulosic material, from about 1% to about 50% by weight of densified thermoplastic material, and from about 0 to about 50% by weight of coal. The cellulosic material, densified thermoplastic material and coal are ground from about 80 Mesh to about 200 Mesh, and then blended into a mixture wherein the contents are evenly distributed throughout. Following the blending process, the mixture is forced through a pelletizer. As the pellets are removed from the pelletizer they are immediately cooled so that the densified thermoplastic particles do not melt. The resulting fuel pellets produce from about 10,000 BTU per pound to about 16,000 BTU per pound and leave an ash deposit of about 0 to about 6% by weight, and a sulfur dioxide output of about 0 to about 3% by weight.
