  • Some aspects of fluidization (Voidage, particle size concepts, minimum fluidization velocity, transport velocity and other basic concepts)
  • Fuel Properties with significance for operation and performance (coal, biomass, and waste)
  • Overall Thermal Design (Heat balance, heat transfer and allocation of heat transfer surfaces, Influence of fuel, co-combustion,)
  • Key Design Factors:  Bed, Furnace, Cyclone, Loop Seal, Fuel feed system and location, External heat exchangers

Day Two

  • Bed Inventory and PSD Management (Pressure drop, and Pressure measurements, circulation loop)
  • Ash Systems and Management (bottom ash, fly ash, ash cooling, recycling)
  • Bed Agglomeration and deposits on heat transfer surface
  • Control Aspects (Bed material control, Bed temperature control)
  • Air Emissions (Type of emissions and how they are influenced, CO, NO, SO2, etc)
  • Part Load and Transient Operation
  • Performance, Troubleshooting
