The report presents further results of studies of the environmental aspects of the pressurized fluidized-bed coal combustion process, using the 218 kg coal/hr 'miniplant' continuous-combustion/sorbent-regeneration system (0.63 MW equivalent), and a 13 kg coal/hr bench-scale system. Previous combustion studies on the miniplant combustor were extended to investigate emissions of SO2, SO3, NOx, and particulates during combustion of a high-sulfur coal, and with the use of precalcined limestone as the SO2 sorbent. Percentage SO2 removals obtained with the high-sulfur coal were similar to earlier ones with intermediate-sulfur coal. Precalcined limestone proved to be as effective as dolomite (on a Ca/S molar basis) in removing SO2. The performance of the miniplant regenerator was demonstrated in an uninterrupted 125-hr run with continuous circulation of sorbent between the combustor and the regenerator. A granular bed filter for high temperature/pressure flue gas particulate removal was installed on the miniplant: initial shakedown was completed with a 24-hr continuous run. Sampling was completed on the miniplant combustor for comprehensive analysis of emissions.
