摘要
2012年3月发现锅炉饱和蒸汽钠离子含量连续超标,最大达到76μg/L。通过检查、分析研究和实验结果,提出汽包裂纹处理的方法及注意事项。将锅水协调pH-磷酸盐处理工艺改为低磷酸盐处理工艺,并修改相应控制标准,提出解决汽包水位偏差和波动的相应对策。经处理,饱和蒸汽钠离子含量达标。
In March 2013, it was found that the sodium （Na ＋ ） content in saturation steam continuously exceeded the stand- ards, and the maximum value reached 76μg/L. Through the inspection, analysis and test results, the treatment and cautions for the cracks of steam drum are proposed. Meanwhile, the pH - phosphate treatment process is changed to low phosphate treatment process, and the relevant control standards are revised. The countermeasures for the deviation and fluctuation of wa- ter level in steam drum are proposed too. After the treatment, the sodium content in saturation steam reaches the standards.
