Abstract:
1. A method of fabricating a heat exchanger having a heat exchange body and a plurality of seals disposed between a heat exchange body and a housing, the method comprising: preparing a surface of the heat exchanger that is susceptible to pitting and structural deterioration when exposed to a corrosive environment, the heat exchanger adapted for use in reducing a temperature of a flue gas emitted from a coal burning power generator prior to said gas being released into the environment; and powder coating the surface, the powder coating being a resilient coating robustly adhered to the surface and having a high acid resistivity and configured to inhibit the adherence of, and decrease the accumulation of, sulfur-based particles to the powder coated surface, thereby forming a barrier that resists corrosion inducing agents created by the coal burning power generation process from contacting the surface, wherein the coating is a uniform coating with an area density of between about 1.55 g/cm
