Flue Gas Desulfurization Systems
Of all the problems that could beset a flue gas desulfurization (FGD) system, corrosion is the one that most challenges system designers, manufacturers and users alike. The environment within a FGD system is a complex solids, liquids, and gases interface characterized by critical temperature fluctuations and turbulent chemical reactions. This activity is bound to take its toll on inner surfaces of ductwork, dampers, piping, pumps, and other vessels.
Since the early days of FGD system design stemming from the Clean Air Act of 1970, Duromar has been heavily involved in erosion, corrosion and process control problems. The combination of erosion and corrosion found in these early FGD systems surpassed the resistance capabilities of many of the construction materials in use at that time. This encouraged Duromar to search for new engineering solutions through the use of “state of the art” polymeric technologies. Duromar recognized early that the key to solving many of these problems would be in the use of 100% solids, multi-functional or novolac epoxy systems. These new systems, while outperforming conventional solvent based coatings, would also be non-hazardous to the applicator and non-toxic to the environment. As FGD systems began to emerge, Duromar worked closely with system designers, engineers and utilities to develop linings and repair materials for the protection of components used in and around these systems.
