In order to achieve the nation's overall energy consumption target and pollutant emission target set by the 11th Five-Year Plan, to build the resource-conservation and environment-friendly society during the 11th Five-Year Plan period (2006-2010), it is crucial to implement the policy of "Large (units) In and Small (units) Out (LISO)" (i.e., replacing small units with large ones) and accelerate the retirement of small thermal units. According to the statistics, the power industry has made a significant progress in SO2 emission reduction during the first half of 2007. Specifically, with 18.3% growth in power generation, the SO2 emission was reduced by 5.2% compared with the same period in 2006. By the end of July 2007, the retired small units have totaled 6950 MW, 85% of which belongs to the five major power generation groups such as Guodian and Huadian. In this article, the achievements and remaining issues in Henan, Jiangsu, Sichuan Power Companies and East China Grid Company were presented and discussed thoroughly.展开更多
电力碳排放的数据质量取决于电网排放因子的准确性。为了获得用于产品碳足迹计算的电网电力碳足迹排放因子,基于电网排放因子数据和计算方法,将核算范围扩展到电力上游的燃料开采与生产、发电设施建设与退役以及电力生产过程,考虑CO_(2)...电力碳排放的数据质量取决于电网排放因子的准确性。为了获得用于产品碳足迹计算的电网电力碳足迹排放因子,基于电网排放因子数据和计算方法,将核算范围扩展到电力上游的燃料开采与生产、发电设施建设与退役以及电力生产过程,考虑CO_(2)、CH4、N2O等温室气体排放,得到2020年中国区域及省级的电网电力碳足迹排放因子。结果表明:华北地区排放因子最高(1.005 t CO_(2)e/MW·h),南方地区排放因子最低(0.470 t CO_(2)e/MW·h),可再生能源占比高的省份排放因子低,全国排放因子显著降低。研究得到的电网电力碳足迹排放因子可为电力碳排放计算提供参考,建议在计算产品碳足迹时优先使用。展开更多
