摘要：This paper presents supercritical coal-fired power stations integrated with CO2 capture and compression systems based on oxy-combustion.The efficiency and key performance indicators of analysed units with different oxygen generation methods have been compared.The following methods are presented: cryogenic,cryogenic-membrane based on polymer membranes,and membrane methods with three-end and four-end HTM membranes.Loss of efficiency in reference to a plant operating in classic arrangement (without CO2 capture) is given for all analysed systems.The main thermodynamic parameters of the considered power units were presented.The paper is a summary of results of the strategic programme ”Development of oxygen combustion technology for pulverised- and fluidised-bed boilers with integrated CO2 capture” carried out by the authors.
