Right now, fossil-fired power plants is the main scheme of generating electricity in Taiwan and steam turbine and combined cycle are still dominant.This study used Life Cycle Assessment with two models, including Eco-Indicator 99 and IMPACT 2002+ from SimaPro 7.1 to analyze major environmental impacts of various types of fossil-fired power plants. Also, IMPACT2002+ was applied to compare potential environmental impacts among clean coal technology facilities (IGCC, supercritical Pulverized Coal and ultra-supercritical Pulverized Coal). Furthemore, Eco-efficiency analysis was used to analyze differences and trends of two fossil-fired power plants(Talin and Tungshiau). Results of LCA analyses indicated that the resource damage was the major environmental impact category by Eco-Indicator99, while the clime change was the most environmental burden by IMPACT 2002+. Over all, the gas combined cycle was the best choice either by results of Eco-Indicator 99 or IMPACT 2002+ for the reason that natrual gas is cleaner than coal and oil. Results of IMPACT2002+ indicated that IGCC was the best compared to supercritical and ultra-supercritical PC. Also, IGCC could have more future advantages due to multiple fuel fesibility. The results of Eco-efficiency analysis demonstrated that some generators of Talin power plant have operated over 30 years so the heat rate efficiency and environmental indicators became worse. On the other hand , the Tungshiau power plant , except NO. 3 generator ,has shown better environmental efficiency because of shifting to natural gas. su-jen lin 林素貞 2009 學位論文 ; thesis 144 zh-TW |
