摘　　要：应用生命周期分析法(LCA),对塔式太阳能热力电站所用设备材料的生产、运输、电站基本建设等3个过程进行了分析,分别计算出3个过程中的能耗及其对环境的影响,并与燃煤发电进行了比较。结果表明,太阳能热力电站每发电10MWh,即可节省能源3.78t标准煤,少向大气排放粉尘、CO2、NOx、SO2分别为498.7熏9933,49.94,78.75kg。太阳能热力发电具有显著的节能和环保效益。Three stages such material smelting, material transportation and power station building were analyzed by means of life cycle assessment, the energy consumption and environmental impact were calculated in each stage, and the comparison with coal-fired thermal power generation were done as well. The results showed that for every output of ten thousands of kWh electric power, the standard coal consumption could be saved by 3.78 t, the emission of dust, CO2, NOx and SO2 could be decreased by 498.7 kg,9 933 kg, 49.49 kg and 78.75 kg. On the basis of above results, solar thermal power generation had be proved that it had remarkable effect on energy saving and environmental protection.
