These studies support development work in atmospheric and pressurized fluidized-bed coal combustion. The relative effects of major economic variables on the economic feasibility of the fluidized-bed reductive decomposition process were determined for coals and sorbents for which cyclic combustion and regeneration data are available. Also, a computational method was developed for predicting the cost of a regeneration system when system size, various economic factors, coal type, sorbent type, and preliminary data on sorbent reactivity are given. A new, automated, atmospheric-pressure, 6-in.-dia, fluidized-bed coal combustion facility is being constructed to study the corrosive effects on materials of construction of (1) agents added to the combustor bed materials to accelerate limestone sulfation rate and (2) combinations of sulfation-accelerating agents and corrosion inhibitors. |
