Abstract
Cold bed and 30 kWth pilot bed tests using circulating fluidized bed (CFB) were conducted to apply oxyfuel technology for waste sludge combustion as a carbon capture and storage technology. In cold bed test, the minimum fluidization velocity (umf) and superficial velocity for fast fluidization was determined as 0.120 m/s and 2.5 m/s, respectively. In the pilot test, air and oxy-fuel combustion experiments for waste sludge were conducted using CFB unit. The flue-gas temperature in 21∼25% oxy-fuel combustion was higher than that of air and up to 30% oxy-fuel combustion. In addition, the concentration of carbon dioxide was more than 80% with the oxygen injection range from 21% to 25% in oxy-fuel CFB waste sludge combustion.
