【摘要】：为获取大型船舶停泊工况下排放因子,选取在广州港停泊的3艘总吨位40×10~3t的大型货柜船为研究对象,登船采集其辅机尾气样品进行分析,并利用"碳平衡法"计算得到基于燃油消耗量的污染物排放因子.实测3艘大型货柜船CO_2排放因子分别为3 096、3 031和3 028 g·kg~(-1);NO_x排放因子分别为61.8、19.9和27.0 g·kg~(-1);CO排放因子分别为8.0、4.0和5.3 g·kg~(-1);SO_2排放因子分别为31.4、41.9和56.7 g·kg~(-1);PM_(2.5)排放因子分别为2.4、1.1和1.5 g·kg~(-1);VOCs排放因子分别为0.13、0.09和0.17 g·kg~(-1).结合广州港进出港船舶类型、船舶抵港次数、船舶停泊时间等调查数据,初步估算2014年广州港船舶停泊工况NO_x、CO、SO_2、PM_(2.5)和NH3的排放量分别为1 231、226、1 229、47.6和0.04 t,其中总吨位为10×10~3~50×10~3t的船舶对NO_x、CO、SO_2、PM_(2.5)和NH3的分担率最大,其次是总吨位50×10~3t的船舶;VOCs的排放量为33.6 t,总吨位3×10~3t的船舶分担率最大.
[Abstract]:In order to obtain the emission factors of large ships under berthing conditions, three large container ships with 40 脳 10 ~ 3 t gross tonnage berthing in Guangzhou Port were selected as the research objects, and their auxiliary exhaust gas samples were collected from board ships for analysis. The pollutant emission factors based on fuel consumption were calculated by carbon balance method. The CO2 emission factors of 3 large container ships measured were 3 096g / kg ~ (3 031) and 3 028 g / kg / kg ~ (-1) respectively. The emission factors of CO were respectively 61.81.9g / kg ~ (-19.9) and 27.0 g / kg / kg ~ (-1) respectively: 8.0 g / kg ~ (4.0) and 5.3 g / kg / kg ~ (-1) / kg ~ (-1) respectively: 31.41.9 and 56.7 g / kg / kg ~ (-1) respectively.) the emission factors of VOCs were 2.41.1 and 1.5 g / kg / kg ~ (-1) respectively. The factors were 0.130.09 and 0.17 g 路kg ~ (-1), respectively. Combined with the survey data of the type of ships in and out of the port of Guangzhou, the number of times of arrival of ships, the time of berthing of ships, etc., It is estimated that the emission of NOX / COX / COSOG / 2PMSP / (2.5) and NH _ (3) are 1231 / 226 / 1229 / 47.6 and 0.04 t respectively in Guangzhou Port in 2014, of which 10 脳 10 / 10 / 39 / 50 脳 10 / 10 / 3t ships with a gross tonnage of 10 脳 10 / 10 / 3 / t have the highest sharing rate for no / x / C / COSO _ 2PMD / 2.5) and NH _ 3, respectively, and NH _ 3 is the highest in the total tonnage of ships with a total tonnage of 10 脳 10 ~ (3) and 50 脳 10 ~ (3) t. Secondly, the emission of VOCs from ships with a gross tonnage of 50 脳 10 ~ (3) t is 33.6 t, and the ship's share rate of 3 脳 10 ~ (-3) t is the highest.
