What is a circulating fluidized bed?
The refuse-derived fuel is fed into a circulating, fluidized bed of red-hot quartz sand that is suspended on jets of hot air. This advanced technology provides efficient, low-pollution burnout: The tiny, red-hot sand particles mix with the combustion air and the RDF. This creates a particularly intense heat and mass transfer. With a circulating, fluidized bed, plant operators can respond quickly and efficiently to changes in fuel properties, allowing them to incinerate refuse-derived fuels with both low and high heat values. The minimum temperature in the combustion chamber is 850 degrees Celsius.
