前后墙对冲旋流燃烧锅炉由于炉内燃烧组织方式和炉膛结构特点,水冷壁高温腐蚀主要发生在主燃区和还原区的左右两侧墙上,通过锅炉的摸底工况试验,诊断锅炉运行存在的问题,在此基础上进行燃烧优化调整,降低了水冷壁近壁区域烟气中还原性气体和腐蚀性气体的含量,以此来减缓水冷壁高温腐蚀的速率。The high temperature corrosion of water wall mainly occurs on the left and right sides of the main combustion area and reduction zone due to the combustion organization mode and furnace structure characteristics of the front and rear wall opposed swirl combustion boiler.based on the diagnosis of the problems existing in the boiler operation,the combustion optimization adjustment is carried out to reduce the reducing gas and corrosion in the flue gas near the wall area of the water-cooled wall The content of corrosive gas can slow down the high temperature corrosion rate of water wall.
