Description:
The status and potential of granular bed filter (GBF) technology for fine particulate control has been critically reviewed and evaluated with emphasis on high temperature and pressure (HTP) applications. Available theoretical models and experimental data have been evaluated and found to be inadequate for predicting the performance of industrial GBF systems. Additional experimental data were obtained with a bench scale GBF. These data were used as the basis for a clean bed performance model based on inertial impaction as the primary collection mechanism. Predictions were in good agreement with data from industrial GBF systems. The performance and economics of fixed, continuously moving, and intermittently moving GBF systems have been evaluated for HTP applications. This study shows that GBF systems have potential for HTP applications but further development and design improvements will be necessary before these systems can be considered adequate HTP particulate control technologies. Recommendations are made for improving the efficiency and reliability of GBF systems.
