NOVELTY - A system for preparing solid, liquid, and gas product from coal and biomass, comprises: (a) a coal powder grinder and any coal drying device; (b) a first funnel locking system; (c) a coal pyrolytic furnace; (d) a slurry slot; (e) a pump; (f) a coal gasification furnace; (g) a tar recovering unit connected with the pyrolytic furnace; (h) a chilling unit; and (i) a solid-gas separator.    USE - The system is useful for preparing solid, liquid, and gas product from coal and biomass (claimed).    ADVANTAGE - The operation of the system is dependent on the integrated circulation of the heat generated by the system between a pyrolyzing furnace and a gasification furnace and the thermal balance when there is not any external heat supplied in the system; thus, the thermal efficiency of the system is improved greatly and it saves the cost. Moreover, a chilling unit and the chilling medium in the region adjacent to the gas flow outlet of the gasification furnace chill the synthetical gas flow; where the synthetical gas form the chilling unit or the gasification furnace is filled in the pyrolyzing furnace; thus, the operation temperature of the pyrolyzing furnace is controlled in the needed range of the pyrolytic reaction without needing the external thermal source of the pyrolytic reaction.    DETAILED DESCRIPTION - A system for preparing solid, liquid, and gas product from coal and biomass, comprises: (a) a coal powder grinder and any coal drying device; (b) a first funnel locking system; (c) a coal pyrolytic furnace; (d) a slurry slot; (e) a pump; (f) a coal gasification furnace; (g) a tar recovering unit connected with the pyrolytic furnace; (h) a chilling unit; and (i) a solid-gas separator; where the coal powder grinder and any coal drying device, the first funnel locking system, the coal pyrolytic furnace, the slurry slot and the pump, and the tar recovering unit connected with the pyrolytic furnace and the chilling unit are connected via pipes; the gasification furnace is connected with the pyrolytic furnace; and the pipe where the gasification furnace is connected with the pyrolytic furnace and the chilling unit feeds the synthetical gas from the chilling unit or gasification furnace in the pyrolytic furnace to keep the operation temperature of the pyrolytic furnace in the needed range of the pyrolytic reaction without needing the external thermal source of the pyrolytic reaction. An INDEPENDENT CLAIM is a method for preparing solid, liquid, and gas product from coal and biomass, comprising: (a) grinding or drying coal to obtain grinded or dried coal; (b) feeding the grinded or dried coal in the first funnel locking system and pressurizing; (c) feeding the pressurized coal in the pyrolytic furnace and thermally decomposing the coal in to air flow or tar in the pyrolytic furnace; (d) feeding the tar generated in the pyrolytic furnace in the second funnel locking system and further pressurizing or feeding the tar in the slurry slot; (e) feeding the pressurized tar in the gasification furnace and synthesizing the pressurized tar and slurry gas into gas flow or furnace slag; (f) feeding the synthetical air flow and furnace slag in the chilling unit or sprouting the chilling medium in the gasification furnace to form chilled gas flow in the region adjacent to the gas flow outlet and to make the temperature of the synthetical gas flow lower than to the operation temperature of the gasification furnace but higher than the operating temperature of the pyrolytic furnace; (g) discharging the furnace slag in the chilling unit or gasification furnace to perform water quenching process; (h) feeding the synthetical gas in the solid-gas separator from the chilling unit or gasification furnace to separate the same into solid or pure synthetical gas; (i) circulating the pure synthetical gas in the pyrolytic furnace to keep the temperature of the pyrolytic furnace in the range of the pyrolytic reaction; and (j) feeding the pure synthetical gas and the pyrolytic gas flow in the tar recovering unit from the pyrolytic furnace to separate the same into the final synthetical gas and tar; where the pure synthetical gas is fed into the pyrolytic furnace to keep the operation temperature of the pyrolytic furnace in the needed range of the pyrolytic reaction without needing the external thermal source of the pyrolytic reaction.
