NOVELTY - The method comprises transporting a solid fuel briquette through a heat treatment facility, heating the solid fuel briquette as the solid fuel briquette is moved through the heat treatment facility to a specified internal temperature, and maintaining the specified internal temperature for a specified duration of time of 30 seconds. The solid fuel briquette comprises a binder. The specified internal temperature is 400 degrees F. The solid fuel briquette is transported through a cooling station to cool the solid fuel briquette prior to transporting the solid fuel briquette to an accumulation site.    USE - The method is useful for heat treating a solid fuel briquette such as a biomass product, an agro-forestry product, a coal, a sub-bituminous coal, a bituminous coal, a waste coal (claimed), coke, charcoal, peat, wood, briquettes, biodegradable waste, wood-chips, wood-pellets, agro-forestry pellets, living and recently dead biological material or biomass crops such as miscanthus, switchgrass, hemp, maize, poplar, willow, bamboo, sorghum, eucalyptus, pinus, coconut, sunflower, palm, sugar cane, algae, bagasse, straw, grass, vegetable residues and organic garbage to remove contaminants and reduce moisture content.    ADVANTAGE - The method is capable of effectively, rapidly, controllably and economically treating the solid fuel briquette in an environmental-friendly manner, improves the quality of the solid fuel briquette by removing non-coal products, prevents the optimum burning characteristics of the solid fuel briquette and the development of thermally aberrant solid fuel, and provides the solid fuel briquette with sufficient structural integrity and high resistance to degradation upon exposure to water.    DETAILED DESCRIPTION - The method comprises transporting a solid fuel briquette through a heat treatment facility, heating the solid fuel briquette as the solid fuel briquette is moved through the heat treatment facility to a specified internal temperature, and maintaining the specified internal temperature for a specified duration of time of 30 seconds. The solid fuel briquette comprises a binder. The specified internal temperature is 400 degrees F. The solid fuel briquette is transported through a cooling station to cool the solid fuel briquette prior to transporting the solid fuel briquette to an accumulation site. The cooling station comprises a surface application of cooling chemicals to control the solid fuel briquette temperature, a facility for applying a cooling gas to control the solid fuel briquette temperature, a facility for applying a mist of water to enable evaporative cooling of the solid fuel briquette, and a low oxygen environment. The heat treatment facility comprises: a low oxygen environment, which is obtained by injecting steam into the heat treatment facility; and an electromagnetic energy source or a furnace. The structural integrity of the solid fuel briquette is sufficient to enable obtaining a heat-treated solid fuel briquette. The solid fuel briquette is placed in an insulated vessel until the solid fuel briquette reaches a specified internal temperature. The inert gas is introduced to the vessel when the briquette reaches the specified internal temperature. The oxygen is partially or completely removed from the vessel when the briquette reaches the specified internal temperature. An INDEPENDENT CLAIM is included for a solid fuel briquette.
