Operating experience of the first CFB boiler in Spain: HUNOSA`s ``La Pereda`` power station

HUNOSA`s ``La Pereda`` cogeneration facility utilizes one Foster Wheeler circulating fluidized bed boiler which produces 185,000 Kg/h of superheated steam to generate 50 MW of electricity. HUNOSA, a Spanish public mining company, uses as design fuel a mixture of 60% culm waste, 35% run off mine coal and 5% wood waste, with a High Heating Value as low as 8,742 Kj/Kg, and an ash content as high as 61%. The valorization of this waste fuel, which is a subproduct of the company`s local mining activity, was attempted for the first time in Spain, and was possible by using a circulating fluid bed boiler. Foster Wheeler had previous experience firing waste fuels of this type. One of their installations, the Mount Carmel station in Pennsylvania, which uses high ash anthracite culm as design fuel to generate 45 MW of electricity and steam as heating medium for a 40,500 m{sup 2} green house complex, was the reference plant for this project. This paper summarizes La Pereda`s boiler main design characteristics which enabled a successful and efficient unit start-up and initial operation, and describes the results attained during its first year of operation. This project was elected to be partially financed by the European Community, through the Funds for Regional Development, and the General Directorate for Energy within the THERMIE program, as well as by other Spanish official entities. It is the first installation in operation with a circulating fluidized bed boiler in Spain and will serve as a basis to develop an important program of environmental regeneration by using low grade energy resources which were not susceptible to being used until now. The authors believe that the case described might be of interest to all those considering the potential use of waste fuels of this type for steam and electricity generation.
