Stopped beiler corrosion and protection of a hot-water boiler

The phenomenon of corrosion occurred in a stopped hot-water boiler is a ubiquitous problem for heating boilers in northern areas.Employing appropriate methods of protection for a stopped boiler makes it possible to prolong the service life of the boiler and improve its security of run.The mechanism and harmfulness of the corrosion in a stopped hot-water boiler were analysed theoritically.The two novel protection methods, wet-protection measures and dry-protection measures,were proposed.The principles and concrete operating sequences of the two methodswere clarified in detail. The result of experiments shows that the methods are effective for the prevention of the corrosion in a stopped hot-water boiler.The achievement of research has certain directive significance to the run and protection of the boilers.
