此文通过理论分析与实践，对大容量锅炉在建成投产前不进行酸洗而代之以碱处理的可行性进行了论证，认为把锅炉的首次酸洗移到投产后的检修中进行，能节省大笔清洗费用，缩短机组建设工期，避免锅炉酸洗后转入保护状态给施工造成的诸多不便；更重要的是用碱处理代替新建大容量锅炉的酸洗在技术上将更为合理。 This paper through the theoretical analysis and practice of large-capacity boilers before the completion of production without pickling and the feasibility of substituting alkali treatment was demonstrated that the first pickling shift to the boiler after the commencement of maintenance, can Save a lot of cleaning costs, shorten the construction period of the unit, to avoid the boiler pickling and then transferred to the protection of the state caused a lot of inconvenience; more importantly, alkali treatment instead of the new high-capacity boiler pickling technically more reasonable.
