Caustic Corrosion - an overview | ScienceDirect Topics

Feb 10, 2011 · In fire-tube boilers, a similar type of acid corrosion sometimes occurs if dosing of sodium bisulfite is adopted for the chemical bonding of oxygen. Particularly, when this is applied not in addition to but instead of thermal deaeration, there will usually be an extremely high sulfate concentration in the boiler water.

Boilers - University of Alabama

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

Fouling - Wikipedia

Fouling is the accumulation of unwanted material on solid surfaces. The fouling materials can consist of either living organisms or a non-living substance (inorganic or organic).Fouling is usually distinguished from other surface-growth phenomena in that it occurs on a surface of a component, system, or plant performing a defined and useful function and that the fouling process impedes or

WATER-TUBE BOILERS

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …
