| 摘 要： | 人们已注意到N2O既是温室气体之一,又是同温层中破坏臭氧的重要物质。N2O在循环流化床（CFB）燃烧系统中会大量产生,由于近年来作为废物燃烧器的CFB被广泛地应用,因此废物燃烧过程中N2O生成特性研究已经成为新的焦点。1995年12月,在一小型石英CFB燃烧系统中观察了活性污泥燃烧。试验结果显示:①在850℃时N2O排放超过1830 mg/m3;②活性污泥中N向NO和N2O的转换率与煤炭相比低,③N2O的排放受烟气中O2浓度的影响。

| Abstract: | N2O have been paid attention to not only one of the greenhouse gas but also destruction ozone at stratosphere. N2O is released more at the process of combustion at circulating fluidized bed （CFB）. Recent years, as refuse fuel combustor CFBC was used widely. With the refuse fuel combustion more and more, the studies of N2O formation characteristics had been a new focus. The sludge combustion was observed in the small scale quartz CFB combustion system in Dec. 1995. The experimental result shown that 1) N2O emission is over 1000ppm at 850℃ in CFB; 2) the conversion rate of fuel-N of sludge converting NO and N2O is lower than coal; 3) N2O emission was influenced by O2 concentration in flue gas. |
