In order to develop a reliable system of a ceramic filter for particulate collection at high temperatures like Pressurized Fluidized Bed Combustion (PFBC), an experimental study was carried out to observe the characteristics of the ceramic filter utilizing a simple block weigh-down. One block weigh-down fixes four commercial filter elements coincidentally by pressing down the individual venturi diffuser. Its operational performance was investigated in the temperature range of 600-800 degrees C in a bench scale unit using oil combustion gas into which fly ash was fed. The transient aspects of the temperature and pressure in the pulse cleaning system were also observed during the pulse cleaning.
