摘要
在对燃气和燃煤发电的全生命周期清单分析的基础上,引入环境外部成本概念,计算两种火力发电的生命周期成本.分析结果表明,天然气发电生命周期过程中CO2总排放量为412.78 g/(kW.h),仅为燃煤排放量的48%,其他废气如SO2、CO和PM的生命周期排放总量分别为燃煤的10%,24%和8%.天然气发电的生命周期成本为0.4548元/(kW.h),其中外部成本是0.0587元/(kW.h),仅为燃煤发电的39%.
The life cycle cost of two thermal power generation costs are calculated and analyzed based on the whole life cycle inventory analysis and the concept of environmental costs. The results indicated that the life cycle CO2 emissions of natural gas power generation is 412.78 g/（ kW · h）, 48% of coal - fired power generation. Other emissions such as SO2, CO, and PM are 10%, 24% and 8% of coal - fired power generation respectively. The life cycle cost of gas power generation is 0.454 8 RMB/（kW·h）, and its external cost is 0.058 7 RMB/（ kW · h）, only 39% of coal - fired power generation.
