低温自然环境下基建锅炉柠檬酸清洗的工艺实施

Technology implementation of new boiler citric acid cleaning on low ambient temperature

在两台亚临界基建锅炉启动前化学清洗过程中,根据小型试验、现场状况,对柠檬酸化学清洗工艺的化学清洗临时系统设计及安装、柠檬酸酸洗、酸洗后水冲洗、钝化等阶段进行了工艺优化调整,使得在新疆寒冷冬季的自然环境下,锅炉清洗质量优良。

On the basis of small test, the scene of citric acid chemical cleaning process condition,chemical cleaning temporary system design and installation, citric acid pickling, pickling water to rinse, after stage of the process passivation were optimized. Excellent cleaning quality for two new critical infrastructure boiler before starting were acguired, in xinjiang, make a cold natural environment.
