AIR NOZZLE OF A CIRCULATING FLUIDIZED BED BOILER, CAPABLE OF PREVENTING ABRASION DUE TO THE TURBULENCE IN THE COMBUSTION AIR

摘要

PURPOSE: An air nozzle of a circulating fluidized bed boiler is provided to smoothly spray combustion air without colliding combustion air sprayed from an adjacent air nozzle and to minimize the loss of pressure due to turbulence in the combustion air. CONSTITUTION: An air nozzle(10) of a circulating fluidized bed boiler(1) comprises an inlet(11) and a spraying hole(13). The inlet is formed to vertically flow air which flows to the lower end portion. The spraying hole is divided to the left side and the right side from the upper end of the inlet and is extended to the lower direction. The spraying holes extended to the right side are individually formed to the upper end of the inlet and the spraying hole.
