摘要
在2×35 t/h循环流化床锅炉运行过程中,风帽、埋管和旋风分离器顶部等部位发生严重磨损问题。在锅炉改造中,对风帽进行了调平,对埋管加装了防磨措施,并对旋风分离器顶部易发生磨损的部位辐射了耐火浇注料。并在运行过程中严格控制空气过剩系数在1.3以下。运行结果表明,锅炉的磨损问题得到大幅度缓解,在一年的运行过程中没有发生锅炉的非停。
In the operation of the 2 × 35 t/h circulating fluidized bed boiler, there were serious erosion on the air nozzles, immersed tubes and the flue gas exit area of the cyclones. In the boiler retrofits, anti abrasive measures and refractory linings were added to the immersed tubes and the exit area After the boiler retrofits, the above problems become much the past year＇s operation. of the cyclone, respective, as well as the air caps leveling. more relieved and the there was no unplanned downtime in
