The paper presents preliminary results of performance tests conducted at the Mid-Connecticut Refuse-derived Fuel Facility in February 1989. Objectives of these tests were to evaluate the effects of combustion and flue gas cleaning process conditions on air pollution emissions and residue properties. A cursory analysis of test results support the following tentative conclusions: (1) Combustor emissions of CO and PCDD/PCDF as measured at the SDA inlet were sensitive to the amount and distribution of OFA. Combustion air distributions which result in poor mixing and low excess air margins are believed to be the primary causes of increased CO emissions. (2) PCDD/PCDF stack emissions of < 0.40 nanogram/standard cubic meter were achieved at the Mid-Connecticut Facility when good operating conditions were maintained on both the combustion and FGC processes. (3) FF outlet concentrations of PCDD/PCDF depend on SDA/FF operating conditions. The lowest emissions were associated with medium to low gas temperatures at the SDA outlet, while the SDA lime slurry flow rate was set to provide medium to low SO{sub 2} concentrations at the FF outlet.
