The report gives results of an investigation of particulate, NOx, and trace element control for atmospheric and pressurized fluidized-bed combustion (FBC) systems used with coal. A model, developed previously to project the loading and size distribution of particulate emissions from FBC systems, was used to permit an integrated analysis of particle control options for FBC. An experimental 150 scf/sec high-temperature/-pressure particulate control test facility, treating simulated flue gas, was constructed and shaken down to permit investigation of alternative particulate control devices. Available data on NOx emissions from FBC, and on NOx formation and decomposition, are reviewed to identify significant FBC operating parameters affecting NOx emissions, and to assess formation/decomposition mechanisms that may be controlling in FBC. The previous thermodynamic projections of trace element emissions from FBC were expanded to include aluminum, iron, titanium, cobalt, chromium, manganese, molybdenum, and nickel. These projections provide a first-level approximation of the distribution of volatile and condensed phases of compounds of these metals in FBC effluent streams.
