摘　　要：超临界墙式切圆锅炉投用后,不久发生了水冷壁管结焦现象,针对燃烧器布置特点,对一次风燃烧器喷口偏向炉心偏转19°,使假想切园直径变小。使煤粉充分燃烧,解决水冷壁结焦现象。Not longer after Supercritical wall tangential boiler come into use, pipe shell of water wall happened coking phenomenon, aiming at the characteristic of arrangement of the burner, we try to de- fleet the nozzle of primary air burner to the centre of boiler for 19°, making the diameter of imaginary circle become smaller. So the pulverized coal can be sufficiently burned. And the water wall coking phenomenon can be solved.

关 键 词：水冷壁结焦 结焦原因分析 燃烧器喷口改造
