Utilizing biomass and waste for power production-a decade of contributing to the understanding, interpretation and analysis of deposits and corrosion products

This paper summarizes our findings, including recent activities on: (1) deposit formation during coal-wheat straw co-firing in suspension-fired boilers; (2) a pilot-scale study of ash and deposit formation in the Sandia Multi-Fuel Combustor (MFC); (3) a full-scale measuring campaign dealing with the effect of co-firing of biomass on the ash and deposit formation; (4) a full-scale measuring campaign addressing low-temperature corrosion of tubes in the air pre-heater of a straw-fired utility boiler; (5) a lab-scale study of the corrosion of superheater materials in straw-fired utility boilers, and, finally; (6) a fundamental study on ash and deposit formation in municipal solid waste incinerators. The paper provides insight into the experience gained on ash, deposit and corrosion formation in thermal fuel conversion systems fired with solid non-fossil fuels, and focuses attention on how these results fit into our current understanding of this subject. A complete and updated list of references covering our research activities within this area during the last decade is provided. In addition, a brief overview of current and future research activities is provided.
