Pressurized Fluidized Bed Combustion Combined Cycle Power Generation, namely, PFBC is the clean coal technology, utilizing gas turbine and steam turbine, which is high efficient and friendly to earth. In early 90's, 70 MW class PFBCs had started demonstration and commercial operation all over the world. Kyushu Electric Power Company decided to apply this technology as the real commercial unit, the world largest capacity 360MW, and put into commercial operation in July 2001. To make PFBC feasible as a large scale commercial plant, new technology was applied, such as the unique design of hexagonal furnace, new high strength steel developed for pressure vessel, etc, to reduce size and weight of the plant. As a result of the commissioning, the gross efficiency at the grid, 41.8 %, was demonstrated, being very excellent compared to other coal fired power stations.
