NOVELTY - System (200) for producing combustible biomaterial, comprises a: lignocellulose rupturing device (208) for rupturing lignocellulose in biomass to produce a ruptured biomass material, where the ruptured biomass material has an inorganic material; washing subassembly (210) designed to wash the ruptured biomass material with a solvent, and to produce an inorganic-material-enriched solvent and an inorganic-material-depleted ruptured biomass; and pyrolyzing subassembly (214) for pyrolyzing the inorganic-material-depleted ruptured biomass to produce a combustible biomaterial.    USE - The system is useful for producing combustible biomaterial, which is useful to produce biocoal (claimed).    ADVANTAGE - The system: provides a combustible biomaterial without fouling and slagging in the combustion chamber, and with higher throughputs and lower capital costs, when compared with conventional systems; utilizes the solvent, which is recyclable and effectively removes the non-combustible inorganic material from biomass; effectively ruptures the lignocellulose to access the combustible and noncombustible inorganic components inside biomass; is capable of processing different types of biomass; provides the low cost combustible biomaterial in the form of pellets, which can easily transported and stored and used as an energy source; eliminates the emission of harmful green house gases; utilizes pyrolyzing subassembly that effectively degrades long-chain polymers of hemicellulose and cellulose into a simpler form e.g. glucose, which can be converted to energy under high-temperature conditions; provides an energy-dense end and hydrophobic biomaterial, thus increasing the gross calorific value of the combustible biomaterial; facilitates the improved separation of solvent from the treated biomass, without incurring high costs, and reduces labor-intensive and time-consuming; avoids the wasting of heat during pyrolysis; facilitates multiple washing cycles, thus avoiding the absorption of inorganic materials by biomass in downstream bins; and consumes relatively small amounts of solvent for washing of large amounts of biomass.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a biomass washing subassembly, comprising: many bins, each of which is designed to hold a single discrete amount of biomass; a solvent dispenser for dispensing solvent at a location from where the solvent washes a first discrete amount of biomass, which is inside the first of many bins, to produce a first effluent stream; a first pump for pumping the first effluent stream to a location from where the first effluent stream washes a second discrete amount of biomass, which is inside the second of many bins, to produce a second effluent stream.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of the system for producing the combustible biomaterial from biomass.
