摘要
分析了华电莱州发电有限公司#2锅炉水冷壁侧墙高温腐蚀的情况及生成原理,提出了在各燃烧器层两侧增加侧壁风,以削弱和预防侧墙水冷壁还原性气氛的生成,进而达到防止水冷壁侧墙高温腐蚀的目的。改造后进行了侧壁风门开度试验,根据试验结果确定不同负荷下侧壁调门开度,并总结了该方案的优点及注意事项。
After analyzing Huadian Laizhou Power Plant Company Limited No. 2 boiler water wall high-temperature corrosion causes,the plan of to provide side wind on the both side of furnace to reduce and prevent reducing atmosphere and high-temperature corrosion on side water wall was claimed. After reconstruction,cheek damper opening test was carried out. Based the test result,the advantaged and notes of reconstruction plan were summarized.
