Efficiency of Supercritical Coal Power Stations with Integrated CO2 Capture and Compression Systems Based on Oxy-combustion Technology
Journal Title: Acta Energetica - Year 2016, Vol 26, Issue 1
Abstract
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.
