    • A method of combusting carbonaceous fuel in a combustion system. The combustion system includes a source of oxygen and a furnace. The method includes the steps of (a) feeding fuel and combustion gas including oxygen and recycling gas into the furnace for combusting the fuel with the oxygen and producing exhaust gas that includes CO 2 , water and excess oxygen as its main components, (b) conducting the exhaust gas discharged from the furnace into a scrubber so as to remove pollutants from the exhaust gas, (c) dividing the exhaust gas into a first exhaust gas stream and a second exhaust gas stream, and conducting the second exhaust gas stream as a recycling gas stream into the furnace, (d) conducting the first exhaust gas stream into a CO 2 purification and capturing unit (CPU) to produce one or more condensate streams, a purified liquid CO 2 stream and a vent gas stream that includes remaining CO 2 , (e) discharging the purified liquid CO 2 stream from the combustion system, (f) conducting the vent gas stream into an adsorption unit so as to adsorb compounds, including remaining CO 2 , from the vent gas stream to an adsorbing material and to produce a pass-through gas stream, and (g) regenerating the adsorbing material to produce a desorbed gas stream that includes at least a portion of the adsorbed compounds, and conducting at least a portion of the desorbed gas stream into the furnace.
    • 一种在燃烧系统中燃烧碳质燃料的方法。 燃烧系统包括氧源和炉。 该方法包括以下步骤:(a)将包括氧气和再循环气体的燃料和燃烧气体送入炉中,用于燃烧燃料与氧气并产生包含CO 2,水和过量氧气的废气作为其主要成分,(b)导电 废气从炉排出到洗涤器中,以排除废气中的污染物,(c)将排气分成第一废气流和第二废气流,并将第二废气流作为回收 (d)将第一废气流引入二氧化碳净化和捕集单元(CPU)以产生一个或多个冷凝物流,纯化的液体CO 2流和包括剩余CO 2的排出气流(e )从燃烧系统排出净化的液体CO 2流,(f)将排出气流引入吸附单元,以将包括剩余CO 2在内的化合物从排放气流吸附到吸附剂 并且产生直通气体流,和(g)再生吸附材料以产生包含至少一部分吸附化合物的解吸气流,并将至少一部分解吸的气流导入到 炉。
