3.2 Biomass Addition to Coal Based Large Fluidized Bed
Boilers
There is also one in development that allows some percentage of biomass addition
to coal in large scale
fl
fluidized bed boilers to gain advantage of using renewable
fuels at high boiler ef
ciencies.
3.3 Biomass-Based Fluidized Bed Combustors
Biomass-based FBC are usually in a smaller size range. They typically range from
30 to 130 MWth. BFBCs as well as CFBCs are applied. Usually different biomass
fuels are burned at the same time in the same combustor. However coal, sludges or
waste is used as well. Such steam generators are used, for example, in the pulp and
paper industry. There are on-going projects to increase their availability and to
decrease their costs. A special focus is on fuel characterization and to burn the fuel
mix in an optimum way.
