The distribution of 24 trace and minor elements in the feed and exit streams from a fluidized-bed combustor equipped with a pulse-jet baghouse for particulate control was investigated. Lignite feed was the major source of aluminum, barium, beryllium, iron, sodium and titanium entering the combustor. The limestone feed was the major source of calcium, magnesium and manganese entering the combustor. Both lignite and limestone were significant sources of chromium, cobalt, nickel, potassium, silicon, vanadium and zinc. Most of the elements left the combustion system in either the primary cyclone catch or the bed drain. The secondary cyclone and baghouse collected most of the remaining trace and minor elements. Particulate emissions to the atmosphere were very low ranging from 0.00026 to 0.00040 lb/10/sup 6/ Btu. Emissions of trace and minor elements, which were also very low, are presented in this report.
