Corrosion in Steam and Condensate Piping Contents: Unlike erosion, which is the physical degradation of a material due to the flow of water, wind, or debris, corrosion is the degradation of a material caused by chemical reactions.
In the boiler plant, cold-end corrosion is related to air pre-heater tubes and condensers. Factors responsible for high corrosion rates are the fuel sulfur content, high dew point of the acidic constituents of flue gases , and moisture content of the fuel and air used for combustion.
Tubes Heat exchangers with shell diameters of 10 inches to more than 100 are typically manufactured to industry standards. Commonly, 0.625 to 1.5" tubing used in exchangers is made from low carbon steel, Admiralty, copper, copper-nickel, stainless steel, Hastelloy, Inconel, or titanium. Tubes can be drawn and thus seamless, or welded.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.. A boiler or steam generator is used wherever a source of …

Overheating conditions may develop during times of low-load operation when adequate distribution of saturated steam across the tube bank at the inlet header has not been achieved. Soluble-salt deposits may form at a superheater tube inlet as a result of excessive entrainment of boiler water solids with the steam. This can result in restricted flow.
