The SOPROLIF 250 Mwe CFB boiler, installed in the Provence Power Plant located near Gardanne in the south of France, has been the largest CFB boiler in operation since April 1996. The purpose of the project was to repower with a CFB boiler 250 Mwe the existing unit 4 of pulverized coal in order to keep on burning the local high sulfur coal while ensuring an environmentally friendly operation. The erection was carried out according to the schedule. The full load was reached in November 1995 and commercial operation started in April 1996 with 5 months delay due to social and technical problems mainly relative to some boiler and steam turbine auxiliaries rather than to the CFB process itself. The training to prepare the transfer from pulverized coal to CFB boiler was carefully prepared and the new process was well accepted by the operators. The SOPROLIF CFB boiler performances which were carried out in May 97 are in accordance with the expected figures. During the first year of operation, the availability reached the contractual figure, which was determined according to such a prototype. The main operation difficulties were due to the coal moisture, which was higher than expected in winter season (problem never met with the existing PC unit due to the drier process in mills). In addition, to reduce NO{sub x} emission, cyclone modification has been performed during the first year of operation through a main overhaul, which impacted the availability of the first year. Since April 97, the availability has been very high. This paper presents the project, describes the technical experience that EDF got from the first year of operation and states the performance test results.
