AIR DISTRIBUTION NOZZLE FOR FLUIDIZED BED BOILER

摘要

PURPOSE: An air distribution nozzle for a fluidized-bed boiler is provided to prevent the backflow of fluid sand because an air supply pipe is inserted to the inner upper side of an air nozzle cap. CONSTITUTION: An air distribution nozzle for a fluidized-bed boiler comprises a hollow air supply pipe(110) and a hollow spherical air nozzle cap(120). The air nozzle cap is coupled to the top of the air supply pipe. A plurality of air vents(122), each formed in an arc shape, are radially arranged in the center of the bottom of the air nozzle cap in order to discharge air.
