Abstract

The main objectives of this project are to show the viability of modern Circulating Fluidised Bed (CFB) technology in maximising the use of biomass-based fuels in large-scale power generation. This includes providing the means for safe, sufficient and well-controlled biomass fuel supply and handling, and appropriate and safe boiler operation. These objectives are approached from two directions. On one hand, biomass fuels can cause operation problems in fuel storing, receiving and handling systems due to heterogeneous properties of biomass fuels. On the other hand, biomass fuels may induce deposit formation and corrosion problems in boilers during combustion due to the specific chemical characteristics of biomass fuels. Selected topics from the whole fuel 'life cycle' are tackled starting from fuel procurement and handling, going through combustion, deposit formation and corrosion tests to emission control and monitoring. Co-firing tests are carried out with two pilot-scale rigs and at Alholmens Kraft Ltd, which has the world's largest biofuel-fired CFB (550 MW_th, 165 bar / 545°C).
