在使用管理中,重视运行期的安全管理,一些单位企业忽视停用期的保养和防腐工作,甚至不保养造成了锅炉的腐蚀。在我们北方每年锅炉停用期有6-7个月,如没有采取适当防腐措施,锅炉会产生严重的腐蚀。停用时腐蚀既会造成管壁和锅筒减薄又会增加腐蚀物的厚度,使热传导效率下降又会引发沉积物下的介质浓缩腐蚀,给锅炉的安全经济运行带来很大隐患。做好停炉保养工作是非常重要的。因此从管理角度充分重视锅炉停用期的保养工作,从理论上进一步搞清楚停用期腐蚀产生的原因以及该采取的措施。提高锅炉的使用寿命。本文分析锅炉停用腐蚀的原因,介绍停用期保护方法,选择和保养要求。 In the use of management, emphasis on operational safety management, some units of enterprises neglect the maintenance and corrosion of the suspension period of work, or even maintenance caused boiler corrosion. In our northern region, the annual boiler outage period is 6-7 months. If proper anti-corrosion measures are not taken, the boiler will have serious corrosion. When the corrosion is stopped, the corrosion of the pipe wall and the barrel will increase, and the thickness of the corrosive material will increase. The decrease of the heat conduction efficiency will also lead to the concentrated corrosion of the medium under the sediment, posing a great danger to the safe and economic operation of the boiler. It is very important to do the shutdown maintenance work. Therefore, from the management point of view, full attention should be paid to the maintenance of the boiler’s decommissioning period, so as to further clarify the causes of the corrosion during the decommissioning period and the measures to be taken in theory. Boost the life of the boiler. This article analyzes the causes of boiler deactivation corrosion, describes the out of phase protection methods, selection and maintenance requirements.
