采用火用方法建立了系统排放的废弃物和废热分析模型 ,从火用的概念出发分析排放物对环境的影响 ,并对一个增压流化床联合循环 (PFBC -CC)发电系统的环境影响进行分析。结果表明 ,系统排放的CO2 和热量对环境的影响是不可忽视的 ,S元素从SO2 转移到CaSO4 可大大降低系统的环境影响。为了用火用方法建立更全面的环境影响分析 ,还需要对参考环境模型进行更深入的研究。
Based on the concept of exergy, the influence of emissions on the environment was analyzed, and the environmental impact of a pressurized fluidized bed combined cycle (PFBC -CC) power generation system was established. Analyze. The results show that the impact of CO2 and heat released by the system on the environment can not be neglected. The transfer of S element from SO2 to CaSO4 can greatly reduce the environmental impact of the system. In order to establish a more comprehensive environmental impact analysis using the exergy approach, further research into the reference environmental model is needed.
