3.1 The results obtained by these test methods can be used in combination with other test methods for the selection of a lining in flue gas desulfurization (FGD) systems.
3.2 These methods are intended to evaluate effects of heat alone upon a lining system as applied to a carbon steel substrate. These methods do not produce the thermal gradient that may exist in actual applications. Actual lining performance may also be effected by concurrent physical mechanical or chemical effects.
3.3 These methods evaluate major failure modes of linings applied to square test panels.
3.4 The recommended test temperatures of 200°F (93°C) and 350°F (177°C) are based on typical maximum operating zone temperatures in flue gas desulfurizations systems. Other temperatures may be evaluated as desired.
