Abstract  

 Combustion and emission characteristics of refuse derived fuel ( RDF ) were experimental studied in a tubular high temperature furnace. The results showed that: 1 The increase of plastic proportion in RDF and oxygen concentration in combustion air lead the increase of NOx emission; but under the pure oxygen environment of RDF combustion, NOx emission is greatly reduced; 2 SO2 concentration increases with increasing plastic proportion in RDF and oxygen concentration in combustion air,; 3 Oxygen concentration in combustion air does not have significance effect on CO emission when it is less than 80% in oxygen-enriched combustion,. In pure oxygen combustion, increasing the plastic ratio can reduce the CO emissions; CO emissions tended to decrease with increasing oxygen concentration, CO emissions is minimum in pure oxygen condition; 4 The emissions of NOx, SO2 and CO are lower than national standard, which indicated that the RDF combustion with oxygen enrichment is beneficial for the c pollutant emissions reduction.

垃圾衍生燃料富氧燃烧污染物排放特性

为了解决城市生活垃圾直接焚烧产生的二次污染问题,将城市生活垃圾制成垃圾衍生燃料(RDF),在高温管式炉内进行富氧燃烧污染物排放特性研究.结果表明: 塑料比例增加,燃烧过程中NOx浓度增大;氧浓度增加,NOx浓度增大;但纯氧条件下RDF燃烧,NOx浓度大大降低.塑料比例增加,燃烧过程中SO2浓度增大;氧浓度增加,SO2浓度降低.当氧浓度为80%时,CO浓度相差不大,纯氧时,塑料比例增大,CO浓度减小;氧浓度增大,CO浓度呈减小趋势,纯氧时CO浓度最小.NOx、SO2、CO的浓度均低于国家标准,说明RDF富氧燃烧有利于降低污染物排放浓度.
