  • Patent number: 4191534
    Abstract: A novel fuel log is manufactured by pulverizing raw, carbonaceous material to form granules which are mixed with binder in a hopper and then compacted under pressure to form cylindrical logs. To assure thorough mixing of granules and binder, the binder is sprayed inwardly from the hopper wall while the granules are dispensed from above to drop through the spray. The binder thus tends to coat the entire surface of each granule prior to compaction. Because the surface of each granule is uniformly coated with binder, no voids or discontinuities in the structure are formed. The resulting fuel log is highly resistant to chipping and fracturing, and burning is more uniform.
