Design and Development of a Ceramic Hot-Gas Filter for Fossil Energy
- ORNL
Advanced coal-fueled, power generation systems utilizing pressurized fluidized bed combustion (PFBC) and integrated gasification combined cycle (IGCC) technologies are currently being developed for high-efficiency, low emissions, and low-cost power generation. In spite of the advantages of these promising technologies, the severe operating environment often leads to material degradation and loss of performance in the barrier filters used for particle entrapment. To address this problem a monolithic cross-flow ceramic hot-gas filter is being designed and developed. Because of testing necessities, a hot-gas candle-filter which integrates the requirements of the cross-flow filter will be fabricated first. As a result, a high-purity, stoichiometric mullite, nine inch long, closed-end, candle-filter prototype was fabricated at Oak Ridge National Laboratory (ORNL) using gelcasting technology.
