| 摘 要： | 以1000 MW超超临界水冷和空冷燃煤机组为研究对象,采用生命周期分析方法,建立超超临界水冷和空冷电厂生命周期清单,从能源消耗、环境影响、经济性和综合评价指标进行对比分析。结果表明:空冷电厂较水冷电厂在全生命周期内节水3.08×10~8 m~3,水冷电厂生命周期综合评价指标值较空冷电厂低11.7%,缺水地区发展空冷电厂还需要技术和政策的支持。

| Abstract: | A whole life cycle inventory of 1000 MW Ultra-supercritical water-cooled and air-cooled coal-fired power plants was produced by life cycle analysis methodology.Assessment on the energy consumption,the effects to environment,the cost of life cycle and the comprehensive evaluation indexes were comparatively analyzed for the Ultra-supercritical water-cooled and air-cooled coal-fired power plants.The results show that 3.08×10~8 m~3 water will be saved by the air-cooled power plants than one by the water-cooled power plants and the life-cycle evaluation index value of water-cooled power plants will be lower 11.7%than one of air-cooled power plants in a whole life cycle. So technical and policy support is necessary in order to develop air-cooled power plants in dry-land. |
