Abstract
Firing solid biomass fuels with ordinary fuels poses new challenges for power plant operators. Continuous control of biomass fuel feed has major importance in boiler operation especially when co-firing biomass with peat or coal. Performance monitoring of several biomass-fired boilers has been performed by VTT Processes. Monitoring usually includes deposition/corrosion probe measurements and process data analysis. Simultaneously the economy of the boilers is studied in detail with the use of the on-line and long-term operation economics calculators. The developed monitoring methods for deposition rate offer new ways to explore information about the effects of different fuel blends on boiler fouling and work as a new tool for operator’s support. The information can be used in selecting the fuel blend which causes minimum deposition formation. The operational data and operation economics analysis from a 130 MWth BFB-boiler has been used in planning plant’s fuel usage for the next heating season. The whole planning procedure includes analysis of the plant’s technical performance and also the economics of the whole boiler operation. The next stage in this study is to follow the boiler operation with the selected fuel blends.
