1 Scope
This part of GB 18241 specifies the classification and mark, requirements, test method, inspection rules as well as marking, packaging, transport and storage of lining for flue gas desulfurization (hereafter referred to as “lining”).
This part is mainly applicable to the lining laminated to the wet process flue gas desulfurization device to prevent the device from being corroded by wet and hot sulfur dioxide flue gas, condensed sulfuric acid, lime water suspension, calcium chloride solution and other media.
This part is also applicable to other flue gas desulfurization devices under similar wet desulfurization conditions.
