分析了对冲布置锅炉水冷壁高温腐蚀的原因，提出了用贴壁风来解决对冲布置锅炉水冷壁高温腐蚀的办法，并用计算机对３００ＭＷ机组前后墙旋流燃烧对冲锅炉燃烧过程进行了不同工况下的数值模拟，包括改变一次风速度、二次风内外风量比例、内二次风旋流强度、贴壁风的位置和速度等，通过比较得到了较为可行的贴壁风布置方案 The reasons of the high temperature corrosion of the water wall of the hedge boilers are analyzed. The method of using the adherent air to solve the high temperature corrosion of the water wall of the hedge boilers is put forward. The combustion process of the front and rear wall swirling combustion hedge boilers of 300 MW units is carried out under different operating conditions Including the change of the primary air velocity, the ratio of the air volume inside and outside the secondary air, the swirling intensity of the internal secondary air, the position and velocity of the adherent wind, and so on, the more feasible arrangement of the adherent wind is obtained
