Agglomeration of bed material: Influence on efficiency of biofuel fluidized bed boiler
The successful design and operation of a fluidized bed combustor requires the ability to control and mitigate ash-related problems. The main ash-related problem of biomass filing boiler is agglomeration. The fluidized bed boiler with steam capacity of 66 t/h (4 MPa, 440 C) was started up at the Arkh...
