湛江发电厂锅炉长期存在高温再热器局部超温、再热器出口两侧汽温偏差大等问题。原因分析 :锅炉炉膛出口存在残余旋转 ,使水平烟道右下部气流形成高温、高速区 ;中、高温再热器之间无混合联箱 ,无交叉 ,使中温再热器的偏差叠加于高温再热器 ,导致高温再热器右侧的温度更高。据此 ,提出锅炉运行优化和设备改造双管齐下的方案 Zhanjiang Power Plant boiler long-term existence of high temperature reheater local over-temperature, reheater exports on both sides of the steam temperature deviation and other issues. Analysis of the reasons: there is a residual rotation of the boiler outlet furnace, so that the lower right of the horizontal flue gas flow to form high temperature and high speed zone; medium and high temperature reheater mixed without mesa, no cross, the temperature reheater bias superimposed on the high temperature and then The heater, causing the temperature of the right side of the high temperature reheater to be higher. Accordingly, put forward the boiler operation optimization and equipment reform two-pronged approach
