The construction of a bench-scale Circulating Fluidized Bed Absorber (CFBA) unit has been completed, and system calibrations have already been performed. In addition, as a novel method injecting water into CFBA, a toroidal-shaped nozzle was designed and installed in a bed reactor to increase the wetting efficiency of solid sorbents. The experimental set up for low temperature SO{sub 2} removal consists of a bed reactor of 3 inches in diameter and 10 feet in length, two high efficiency cyclones for gas/solid separation, sorbent injection and recycling system, water injection system, gas heating system, and gas flow, concentration, temperature and pressure monitoring system. The toroidal shaped nozzle located at the base of the bed has 12 holes placed symmetrically around the ring at an angle of 50{degrees} with the horizontal, and is made of copper tube.
