The Limay Bataan Power station, a 600 MW combined cycle, is now in its 8th successful year of operation. Operating on this specific heavy fuel oil, which is a high viscosity, high ashbearing heavy fuel residue from the refinery at Limay, requires a skilled and experienced crew as the quality of fuel was subject to major changes which are highly relevant to the operating mode. If not treated properly, this fuel could corrode blades within a short operating period.

This paper describes the experiences gained on the fuel handling from the fuel treatment plant to the turbine and also addresses the operation of the combined cycle. Specific operating problems are discussed. The plant is fully operated and maintained by ALSTOM Power O&M Ltd with its local team that has greatly contributed to the success of the plant.
