In Japan, research and development of the fluidized bed combustion boiler (FBC boiler) for utility and industrial application has been initiated since 1978. At present, for the atmospheric FBC boiler, a unit of 350 MWe output is under construction at Takehara power station, and for the pressurized FBC boiler, a demonstration plant of 71 MWe output has already been installed at Wakamatsu Coal Utilization Research Center. Coal fired operation started in September 1993. Plant shakedown test is now underway. Wakamatsu PFBC Demonstration Plant is fundamentally based on the technology developed by ABB Carbon AB, a Swedish firm. However, various supplemental technologies of Japanese origin have been introduced in this project to improve environmental characteristics, plant heat rate and load controllability. For instances an ultra supercritical (USC) steam turbine and ceramic tube filters are featured in the Wakamatsu plant. The paper describes the outline of Wakamatsu PFBC Project and some major troubles which have been resolved. In addition, the report will provide an update on the operating experience of the Wakamatsu Project.
