摘要
Abstract
In response to the severe high-temperature corrosion problem of the local water-cooled wall of a 1000 MW double tangential boiler,air flow measurement and damper baffle characteristic testing are conducted through cold aerodynamic field tests,and combined with the verification of reducing gas concentration testing in the near wall area of the water-cooled wall,it is determined that the reasons are:under the misleading of large DCS data deviation,the baffle opening is unreasonable during operation,leading to severe oxygen-deficient combustion in the local area,resulting in severe high-temperature corrosion in that area.After adjusting the operating mode,the situation of oxygen-deficient combustion in the area is greatly alleviated,and the possibility of high-temperature corrosion of the water-cooled wall is greatly reduced.关键词
