Abstract

The object of this study is to investigate the emission characteristics of reclamation of refuse-derived fuel (RDF) to evaluate the feasibility of substitution of RDF for current fuels. The cutting oil collected from a canned-food factory was pretreated, mixed with wood dust and bentonite, and was remolded into pellet RDF. Input materials, including coal, wood dust, and remolded RDF, were reclaimed in a steam generation plant. The pollutant characteristics of bottom ash, fly ash, and flue gas were analyzed to evaluate the combustion performance of the tested fuels. The PCDD/F concentration of the flue gas in the runs without coal (19.6 and 21.9 ng I-TEQ Nm–3) was two orders higher than those in the runs with coal (0.226 and 0.017 ng I-TEQ Nm–3) due to partial smoldering. Except for coal, the substitution of RDF for wood dust also reduced the formation of PCDD/Fs. According to the monitoring data for CO, O2, and combustion efficiency, RDF further improved the combustion condition with the aid of coal. The results show that reclamation of RDF is a promising method to take both waste treatment and energy regeneration into consideration.
