"Organic contaminants in emissions from refuse-derived fuel combustion were investigated in a 20-inch-diameter atmospheric fluidized-bed combustor. Combinations of coal/Eco-Fuel/ MSW/ toluene were burned in the combustor with temperatures ranging from 1250 to 1550ÀF. A Source Assessment Sampling System (SASS) was used to sample the stack gas; Level 1 methodology was used to analyze the organic contaminant levels. Combustion efficiencies of 93 to 98 percent were achieved in the test burns. Combustion of the Eco-Fuel generated fewer organic emissions than combustion of coal at similar combustion temperatures. The fine particulate collected by the SASS train filter contained higher concentrations of extractable organics than the reactor fly ash and the SASS cyclone samples. Combustion of a toluene/Eco-Fuel mix generated a large number of benzene derivatives not seen in the combustion of pure Eco-Fuel. Polycyclic aromatic hydrocarbons were the dominant organic compounds contained in the XAO-2 resin extract from coal combustion. A number of different priority pollutants were identified in the samples collected."
