초록 ▼

A pulverized coal combustion burner includes a pulverized coal nozzle, and secondary and tertiary air nozzles provided in concentric relation to the pulverized coal nozzle. A flame stabilizing ring is provided at an outlet end of the pulverized coal nozzle. A separation wall is provided within the pulverized coal nozzle to divide a passage in this nozzle into two passages. A pulverized coal/air mixture flows straight through the two passages, so that recirculation flows of the pulverized coal/air mixture are formed in proximity to the outlet end of the pulverized coal nozzle. As a result, the ignitability of the pulverized coal, as well as a combustion rate, is enhanced, thereby reducing the amount of discharge of NOx.

대표청구항 ▼

A pulverized coal combustion burner comprising: a pulverized coal passage through which a mixture containing pulverized coal and air flows; an air passage for supplying additional air to a flow of said mixture from outside; a wall separating said pulverized coal passage from said air passage; first recirculation flow-forming means provided at a downstream end of said wall for forming recirculation flows of said mixture and said additional air; means for swirling the mixture flowing in said pulverized coal passage, said swirling means having a plurality of openings through which said mixture is supplied and said openings being disposed in a direction of the swirl, and means for converting said swirling mixture into a straight flow.
