Apr 13, 2018 · Chlorine species are highly responsible for high-temperature boiler corrosion in waste-to-energy and biomass sectors. Chlorine species dissolve in the flue gas during fuel combustion. The saturated chlorine salts condense at the relatively cold heat exchanger surfaces (cold trap). It can directly cause corrosion on metallic surfaces.

How Thermal Oxidation Can Increase the Sustainability of a

Waste heat boilers for localized DFTOs must be designed and sized for the peak flow and heat load from each oxidizer but will normally operate at just a fraction of that design capacity. It is obvious that the boilers themselves are capital intensive, but a single centralized waste heat boiler also minimizes installation costs

Boiler Water Treatment Guidelines; Columbia Boiler Co

Use proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.
