Microstructural development of product layer during limestone sulfation and its relationship to agglomeration in large-scale CFB boiler

Agglomeration is one of the major operational problems in fluidized bed system. Agglomeration in a fluidized bed heat exchanger of a 550-MWe circulating-fluidized-bed boiler was investigated, and the particles were found to be agglomerated by two types of microstructures: layer joint and bridge join...
