Bed Agglomeration Problems in Fluidized-Bed Biomass …

Bed material agglomeration was studied experimentally in a fluidized-bed biomass combustor. Four biomass fuels, four bed materials, three bed additives, and three NOx additives were tested in a temperature range of 670−870 °C and at two pressure levels of 1.0 and 1.5 MPa. Two types of agglomeration were observed, a homogeneous and a …
