Emission Characteristics of Thermal Power in Guangdong Province and Influence on Atmospheric Environment

  • 摘要: 采用物料衡算及排放因子法建立了2012年广东省火电大气污染物排放(下称火电排放)清单,并运用WRF/SMOKE/CAMx模型分析火电排放对大气环境质量的影响. 结果表明:SO2、NOx、CO、PM10、PM2.5、VOCs和NH3排放量分别为269 408、539 565、301 257、135 920、65 050、18 790、1 949 t. 300 MW以上的机组对火电排放的贡献较大,但125 MW以下的机组单位煤耗污染物排放较高. 春季、夏季、秋季、冬季火电排放所占比例分别为27.1%、25.4%、24.0%和23.5%,24 h排放呈“三峰三谷”特征;排放量较大的城市为广州、佛山、东莞、江门、汕头、潮州和梅州,不同区域火电排放贡献率顺序为珠三角 (46.2%~52.3%)>广东省东部(26.9%~34.3%)>广东省西部(11.9%~14.4%)>广东省北部(5.5%~10.0%). 8月火电排放对珠三角城市ρ(SO2)、ρ(NO2)月均值的贡献率较高,分别为17.0%、11.1%,其次为10月、4月、1月,其影响集中于火电厂所在城市及下风向区域,对不同城市的贡献差异性较大,具有局地特征;火电排放10月对ρ(PM10)、ρ(PM2.5)月均值贡献率(9.1%、10.6%)较高,其次为8月、4月和1月,影响区域更广,对不同城市的贡献差异较小,呈现区域性特征.
