Summary:PROBLEM TO BE SOLVED: To provide systems and method for high-efficiency power production to achieve simultaneous carbon capture using a solid fuel.SOLUTION: The present disclosure relates to a power production system that is adapted to achieve high efficiency power production with complete carbon capture when using a solid or liquid hydrocarbon or carbonaceous fuel. More particularly, the solid or liquid fuel first is partially oxidized in a partial oxidation reactor. The resulting partially oxidized stream that comprises a fuel gas is quenched, filtered, cooled, and then directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle COstream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The expanded and cooled exhaust stream is scrubbed to provide the recycle COstream, which is compressed and passed through the recuperator heat exchanger and the POX heat exchanger in a manner useful to provide increased efficiency to the combined systems.SELECTED DRAWING: Figure 1 【課題】固体燃料を利用し、同時炭素回収を達成する高効率出力発生のための系および方法を提供する。【解決手段】固体または液体炭化水素または炭素系燃料を用いる場合、完全炭素回収を伴って高効率出力発生を達成するよう適応される出力発生系に関する。さらに特定的には、固体または液体燃料は、先ず、部分酸化反応器中で部分的に酸化される。その結果生じる部分酸化流(燃料ガスを含む)は、急冷され、濾過され、冷却され、次に、燃焼燃料として出力発生系の燃焼器に向けられる。部分酸化流は、圧縮再循環CO2流および酸素と併合される。燃焼流は、タービンを横断して拡張されて出力を生成し、レキュペレータ熱変換器に通される。拡張および冷却排出流は浄化されて、再循環CO2流を提供し、これは、圧縮され、統合系に効率増大を提供するために有用なやり方で、レキュペレータ熱交換器およびPOX熱交換器に通される。【選択図】図1
