| 中文摘要 |
| 对我国不同行业典型燃煤设备─电站锅炉、工业锅炉、工业窑炉和民用灶具燃煤烟气中N2O的排放量进行了实际监测,测定的N2O浓度为1.5-57.4mg/m3.通过对燃煤煤质分析和烟灰、炉渣中C含量测定,计算了不同炉具燃煤煤的氧化率和烟气量,进而得到了各种炉具燃煤N2O的排放因子。根据我国煤炭的消费情况,估算了中国燃煤N2O的排放量为35.686Gg/a(以N2O-N计)。 |
| 英文摘要 |
| In this paper the actual emission of N2O from power station boilers,other industrial boilers,industrial kilns and civil coal fired furnace was measured.The concentration of N2O in flue gases was in range of 1.5-57.4 mg/m3.After analyzing coal to be burned and determining carbon content of the slags and ashes,the efficiencies of coal combustion in different boilers were estimated and the flux of the flue gases were calculated.From these data the N2O emission factor was obtained.According to the coal consume profile of our country,the total emission of N2O from burning coal in China was 35.69 Gg/a(N2O-N). |
