Control of emissions from cofiring of coal and RDF. Final report
- Acurex Environmental Corp., Research Triangle Park, NC (United States)
Research has been conducted toward developing technology for co-firing of coal with municipal solid waste (MSW) in order to reduce emissions of chlorinated organic compounds, particularly polychlorinated dibenzo-p-dioxins and furans (PCDDs and PCDFs). Previous bench- and pilot-scale research has shown that presence of SO{sub 2} can inhibit the PCDD and PCDF formation, and suggested co-firing high-sulfur coal with refuse derived fuel (RDF) to reduce the emissions. The objective of this research is to identify the effect of process and co-firing options in reducing PCDD and PCDF yield from waste combustion. Two types of municipal waste based fuels were used: a fluff refuse-derived fuel (simply referred to as RDF) and a densified refuse derived fuel (dRDF). The coal used was high-sulfur Illinois No. 6 coal. Experiments were conducted in US EPA`s recently constructed Multi-Fuel Combustor (MFC), a state-of-the-art facility with fuel handling and combustion release rates representative of large field units. The MFC was fired, at varying rates, with RDF/dRDF and coal, and sampled for PCDD and PCDF. Tests were conducted over a range of process variables such as lime injection, HCl concentration, flue gas temperature, quench, and residence time so that the results are applicable to a wide variety of waste combustors. The data are used for developing a comprehensive statistical model for PCDD and PCDF formation and control.
