Description

Hot gas cleaning technology has become a subject of world attention in terms of improved plant efficiency and lower flue gas emission from power plant. The application of Ceramic Tube Filter (CTF) to Pressurized Fluidized Bed Combustion (PFBC) combined cycle would be very promising as a clean coal technology.<br>71MWe PFBC combined cycle power plant by J-Power/EPDC in Wakamatsu was operated for approximately 11,500h and achieved extremely low dust emission (<0.2 mg/m3N) using a hot gas cleaning system combining cyclones and full scale Ceramic Tube Filter (CTF). The gas turbine installed downstream of the CTF was protected from the severe erosion with fly ash.<br>CTF is one of the key technologies in hot gas cleaning domain. In this paper, the major concerns of CTF such as the seal mechanism, the pressure drop performance and the optimization in reverse cleaning conditions are reviewed for the commercial use of CTF.
