Abstract. CO 2 emission from pulverized coal-fired power plants (PC) can be efficiently controlled by adopting the oxy-combustion technology, which adds a cryogenic air separation process (ASU) and a flue gas treatment process (FGU) to the conventional combustion process. To understand the thermodynamic properties of the oxy-combustion process, a simulation study and an exergy analysis of a

2019-12-12 · In an oxy-combustion pulverized-coal-fired power plant (PC), a high CO2 content flue gas could be obtained, and this allows CO2 sequestration in an efficient and energy-saving way. To better understand the thermodynamic characteristics of the oxy-combustion process, a detailed exergy analysis of a 600 MWe oxy-combustion PC was carried out. The whole oxy-combustion PC system was …
