This work supports the development of atmospheric and pressurized fluidized-bed coal combustion. Laboratory and process development studies are aimed at providing needed information on limestone utilization, control of emission of alkali metal compounds and SO/sub 2/ during combustion, particulate loadings of flue gas, and other aspects of fluidized-bed coal combustion. This report presents information on: the SO/sub 2/ reactivities and thus the limestone requirements of sixty different limestones, the morphology of a few selected stones, the effect of water in the gaseous mixture on the SO/sub 2/ reactivities of three limestones, the effect of combustion conditions on the attrition of limestones, the effect of temperature on SO/sub 2/ retention by limestone in a carbon burnup cell, the effect of CaCl/sub 2/ and MgCl/sub 2/ additives on the SO/sub 2/ capacity of limestones, the use of diatomaceous earth and activated bauxite to remove alkali metal compounds from simulated combustion gas mixtures, selection of laser spectroscopy methods to be evaluated for the measurement of gaseous alkali metal species in hot flue gases, the application of acoustic dust conditioning to flue gas cleaning, and the conceptual design of a granular-bed filter for cleaning of flue gas in a 200-MWe fluidized-bed combustion facility.
