Patented Linear, Industrial Boiler CleaningWater Handbook - Preboiler & Industrial Boiler Corrosion …1. Priming - This is the ejection of boiler water into the steam take-off and is generally due to one or more of the following: -Operating the boiler with too high a water level. -Operating the boiler below its design pressure; this increases the volume and the velocity of the steam released from the water surface.

Continuous Blowdown Method of Boiler LayupIf no explosive cleaning has been used in the boiler, then shock wave damage is not possible. However, shock wave damage does not always present itself immediately following explosive cleaning. Primary shock wave damage may not cause through-wall damage, and may leak after some time in service due to a different mechanism.Continuous Blowdown Method of Boiler LayupIf the boiler is equipped with a nondrainable superheater, the superheater is filled with high-quality condensate or demineralized water and treated with a volatile oxygen scavenger and pH control agent. The normal method of filling nondrainable superheaters is by
