Co-firing of coal and biomass in Circulating Fluidized Beds

Paper i proceeding, 2006

To fulfil the development needs of OTSC CFB technology, a comprehensive understanding of CFB combustion processes needed to be achieved. Intensive research in laboratory, pilot and fullscale combustors is required to fulfil the abovementioned objectives.In order to study different process characteristics and verify measurements and simulations, experiments were carried out with different size reactors; VTT’s laboratory scale CFB reactor, VTT’s 50 kW pilot CFB reactor, Chalmers’ 12 MW CFB boiler, cold rig and with several commercial boilers.
