The objective of this research is to determine critical properties of wood fuels in respect of power plant availability, to determine the optimal conditions for reducing detriments, and to study the effect of storing and processing of wood fuels on the boiler operation. Both, the CFB and BFB technologies are studied. The project started in December 2000 and it will be ended in March 2003. Experts of the Energy Production research field at VTT Processes carry out the majority of the research activities. Experts in the research field of Mineral Processing, located in Outokumpu, participate in analytics, and the research field of Material and Manufacturing Technology of VTT Industrial Systems in Otaniemi participates in the research on material effects. System Technology Laboratory of Oulu University, under the supervision of Professor Urpo Kortela, is responsible for the power plant automation and for the research on boiler control technology. Co-operation related to the analytics of heat transfer surface deposition and corrosion with the EU's JRC has continued as established in the Combustion of Forest Chips -project but mainly in a so-colled "CORBI"-EU-project. Additionally, VTT co-operates with Swedish Värmeforsk Ab in the form of information exchange on experiences of wood fuel utilization in Swedish power plants. The following companies participate in the project: Etelä-Savon Energia Oy, Foster Wheeler Energia Oy, Kvaerner Pulping Oy, Simpele pasteboard factory of M-Real Oyj and Värmeforsk Ab (Sweden).
