These studies support the development program in atmospheric and pressurized fluidized-bed coal combustion. Laboratory and process development-scale studies are aimed at providing information on limestone utilization, control of the emission of alkali metal compounds and SO/sub 2/ during combustion, particulate loading in flue gas, and other aspects of fluidized-bed coal combustion. This report presents information on the effect of bed temperature, superficial gas velocity and gas hourly space velocity on the removal of gaseous NaCl from hot gas streams by a granular bed of diatomaceous earth; results of experiments in which the adsorption capacity for gaseous NaCl of activated bauxite was measured after regeneration by an aqueous leaching process; and an estimate of the cost of using these two sorbents for alkali metal control in a large PFBC. Results are also presented for studies aimed at the development of an acoustic dust conditioning system, and the evaluation of a high-efficiency cylone for removal of particles from a high-pressure, high-temperature gas stream. The relationship of the SO/sub 2/ reactivity of limestones to internal surface area, pore diameter, and pore volume are examined.
