These studies support the national development program in fluidized-bed combustion. The objective of this program is to develop an economically acceptable process for the regeneration of the partly sulfated limestone product of a fluidized-bed coal combustor, and to obtain the design data needed for the construction of larger regenerators. This report presents information on: a thermodynamic analysis of the one-step reductive decomposition regeneration process, an evaluation of a regeneration process using a rotary kiln, and the use of fly ash for the reduction of gaseous SO/sub 2/ elemental sulfur. In the previous year, studies of the effect of limestone sulfation-enhancement agents (e.g., NaCl and CaCl/sub 2/) on corrosion of FBC structural materials were described. Results of these tests are reported here.
