Coating Layers on Bed Particles during Biomass Fuel

2003-4-18 · Adhesive coating layers on bed particles have been thought to be the cause of the agglomeration in fluidized-bed combustion. The formation of coating layers on particles of different bed materials (quartz, natural sand, and GR Granule) has been studied when the fluidized-bed combustion of various biomass fuels (bark, different types of wood fuel, peat, biosludge, chicken litter, REF, and

Operational problems in biomass combustion

In fluidized bed combustion the alkali metals in the biomass may facilitate agglomeration of the bed material, causing serious problems for using this technology for herbaceous based biofuels. Fluidized bed combustors are frequently used for biomass (e.g. wood and waste material), circulating FBC are the preferred choice in larger units.
