Regeneration of Sulfated Limestone from FBCs and Corrosive Effects of Sulfation Accelerators in FBCs. Annual Report, July 1977--September 1978
The objectives of this program are to develop an economically and environmentally acceptable process for the regeneration of the partly sulfated product of a fluidized-bed coal combustor, to obtain the design data needed for the construction of larger regenerators, and to determine the possible corrosive effect on metallic alloys of sulfation acceleration agents added to the limestone sorbent. A regeneration process model has been developed; the model has been used to investigate the effects of the main variables on regenerator size and performance and to estimate the economic feasibility of regeneration. The results of an investigation of a regeneration process using a rotary kiln in place of a fluidized bed are reported. An atmospheric pressure FBC was placed into operation to study the corrosion of metallic alloys by limestone treated with various sulfation accelerators such as NaCl or CaCl sub 2 . The results of corrosion studies carried out in a laboratory-scale facility are reported. (ERA citation 04:040129)
