Atmospheric fluidized-bed combustion waste management design guidelines: Final report
Atmospheric Fluidized Bed Combustion (AFBC) is a commercially available and applied coal combustion technology used to control SO2 emissions. This process is rapidly gaining utility acceptance. Because physical and chemical properties of wastes generated by fluidized bed combustors differ from those of conventional coal combustion by-products (fly ash and scrubber sludge), typical waste management practices may need to be altered. This report presents technical guidelines for designing and operating the waste management system of an AFBC facility equipped to burn coal. Waste transfer, storage, pretreatment/conditioning, transport, and disposal are addressed. These guidelines are based on current AFBC waste management practices and associated operating problems as well as critical waste properties (e.g., chemical constituents, gradation, density, moisture content, flowability, strength, leachate properties, etc.). Consequently, the report briefly describes the waste management practices of four existing or planned utility installations and four industrial facilities using bituminous coal as their primary fuel source. Results of waste property tests conducted as part of this study, and test data from other studies are reported and compared. Conceptual designs of both new and retrofit AFBC waste management systems are presented to demonstrate the economic impact of AFBC on waste management. Parametric cost sensitivity analyses illustrate the impact of significant design parameters on waste management costs. 111 refs., 81 figs., 58 tabs.
