Two methods of improving efficiency of coal based power generation are integrated gasification combined-cycle (IGCC) and pressurized fluidized-bed combustion (PFBC). Both of these options require high-temperature gas stream particle cleanup for optimum efficiency. Candle filters in a pressurized vessel have received the greatest amount of attention in dealing with this topic, but problems still persist and there does not seem to be clear-cut answer to the problem. This research is an investigation of the candle filter cleaning process, a process known as surface regeneration.;The objective of this research program has been to develop the instrumentation necessary to investigate the surface regeneration process in a room temperature test facility (RTTF).;For this project a room temperature chamber was built to observe the candle filter cleaning process, denoted as surface regeneration. Instrumentation was installed so that pressure histories could be obtained. The pressure histories were timed with digital photographs taken so that an approximation could be made of the pressure drop across the filter required for filter ash crack initiation.
