Abstract
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.
Highlights
Due to the current economic growth, the amount of waste generated has increased rapidly during the last several decades
This study investigated the combustion performance of refuse-derived fuel (RDF), wood dust, and coal
For Group I, the PCDD/F concentrations of flue gas (19.6 ng I-TEQ Nm–3 in run-1 and 21.9 ng I-TEQ Nm–3 in run-2) were two orders higher than those (0.017 ng I-TEQ Nm–3 in run-3 and 0.226 ng I-TEQ Nm–3 in run-4) for Group II, indicating that smoldering might occur under combustion conditions without coal
Summary
Due to the current economic growth, the amount of waste generated has increased rapidly during the last several decades. The treatment of waste has become a worldwide issue. A European strategy for waste management imposed a regulation on the following waste hierarchy to apply as a priority in waste management and treatment: prevention, reuse, recycling, recovery of energy or resources, and disposal (Directive 2008/98/EC). Among the management and treatment strategies, the recovery of energy from waste has been investigated for the last few decades (Chang et al, 1999). There are three available processes, including combustion, gasification, and pyrolysis, to convert biowaste into energy. The combustion process, generally called incineration, is the most commonly used treatment technology for solid waste (Lombardi et al, 2015)
