摘要：

An exergoenvironmental analysis model based on life cycle assessment (LCA) and Eco-indicator99 was established to explore the environmental cost formation process in the power production process, taking the 9FA gas-steam combined cycle unit as the research object. The environmental impacts of each component throughout the life cycle were clarified, and the environmental impact factors affecting the component output products were divided, based on the exergoenvironmental analysis of system components. The formation process of the environmental impact of the combined cycle unit and the contribution of individual component to the overall system environmental impact were revealed from the component level. Results showed that the environmental impact of the component itself was small for most components, and the environmental impact caused by the damage constituted the main environmental impact of the component, but the environmental impact of the pollutant reduction in the combustion chamber was greater than that caused by the damage. The environmental impact of electricity production from the combined cycle power plant was 5.80 mPts/MJ, which was nearly half of the environmental impact of electricity production from " ultra-low emission" coal-fired power plants. © 2019, Zhejiang University Press.
