抄録

THE CHUGOKU ELECTRIC POWER CO., INC. is constructing Osaki Coal-fired Power Station in NAGASHIMA island, OSAKI in SETO Inland Sea National Park near Hiroshima. This plant which consists of two units of 250MW each is adopting PFBC (Pressurized Fluidized Bed Combustion) in consideration of the environmental advantage and high plant efficiency. This construction started in November 1995 and the test operation of 1-1 unit (250MW) has been under way since March 1999. The commercial operation is planned to start in December 2000. To improve the plant operation and stability, this plant consists of innovative and creative system in which the pressurized fluidized bed is devided into two. Also, other features of this plant are CWP (Coal and Water Paste) supply system as fuel, two stage cyclones as a dust remover system and a single-shaft Gas Turbine for PFBC. This paper mainly discribes the results of the Osaki 1-1 unit's test operation.
