Fluidized Bed Boilers for Biomass - PDF Free Download

Initial bed heating is done using light oil or natural gas start-up burners. Usually the operating bed temperature is between 750 C and 900 C. Control of the bed temperature is easy because of the high heat capacity of the bed. If the properties of the fuel fed to a CFB boiler change drastically, then adjustments to the operation need to be done.
