摘要：

This test program was designed to study the formation and emission of PCDD/PCDF during Refuse Derived Fuel combustion. Tests were conducted in a pilot scale RDF incinerator. Incinerator fly ash hold up for one hour at a temperature of 570-degrees-F resulted in an 8 to 20 fold increase in PCDD/PCDF content. Reductions in RDF load were found to decrease PCDD/PCDF emissions. Fluctuations in RDF feed rate produced increases in PCDD/PCDF emissions. Test results suggest the dominant PCDD/PCDF formation mechanism(s) in the incinerator involve organic compounds in entrained fly ash. A combustion strategy for PCDD/PCDF emissions control has been developed. Natural gas co-firing allows RDF load reduction while smoothing temporal and spatial fluctuations in the furnace.
