LEAN-RICH COMBUSTION BURNER HAVING CHARACTERISTICS OF REDUCING POLLUTIONAL MATERIAL AND STABILIZING FLAME

摘要

PURPOSE: A rich-lean burner having a pollutant reduction property and a flame stabilization property is provided to reduce pollutant, and improve a flame stabilization property. CONSTITUTION: A space in which rich gas mixture flows is formed inside of a rich/lean burner having a pollutant reduction property and a flame stabilization property. First flame hole pieces(110) are formed at specific intervals on the upper surface of the burner. Multiple second flame hole pieces(120) are formed between the first flame hole pieces. Multiple first fuel nozzles are installed on the entrance side of the first flame hole pieces in which the rich gas mixture is flowed in, and multiple second fuel nozzles which has a smaller diameter than the first fuel nozzles are installed on the entrance side of the second flame hole pieces in which the lean gas mixture is flowed in.
