The problem of bed agglomeration has occurred with some Australian black coals in industrial Pressurised Fluidised Bed Combustion (PFBC) in Japanese power plants. This problem was identified as being coal-specific and could significantly limit the operation of the plant. A doctoral thesis study shows that possible factors include both the distribution of coal ash and ash components between bed ash and fly ash and the ash formation process under PFBC conditions, and the temperature at which char particles burn in PFBC.
