Design & Fabrication of Flue Gas Desulfurization System Components for Protective Lining A
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers the design and fabrication of metal components for flue gas desulfurization equipment, including absorber, tanks, chimney liners, ductwork, and associated equipment intended for use in protective lining applications, that are to be lined for corrosion or abrasion resistance, or both. It does not however cover the structural performance of the components and the use of metallic linings. Each of the components shall be designed in such a way that it conforms to the engineering requirements for rigidity wherein the effects of pressure, wind, seismic, and other design loads shall be considered; accessability to welding, grinding, surface preparation, and lining application; shell penetrations; appurtenances inside components such as agitators, anti-swirl baffles, gaging devices, internal piping, ladders, and support brackets; and structural reinforcement members and supports. All internal welds shall be continuous without imperfections and the degree of weld preparation prior to lining shall depend on the type of lining to be applied. Riveted joints and internal bolted joints shall not be used while lap bolted joints shall be avoided whenever possible. Intermittent or spot welding shall not be permitted as well.
Scope
1.1 This specification covers the design and fabrication of metal components for Flue Gas Desulfurization (FGD) equipment, including absorbers, tanks, chimney liners, ductwork and associated equipment that are to be lined for corrosion or abrasion resistance, or both.
1.2 Limitations:
1.2.1 This specification is intended only to define the design considerations for successful application and performance of protective linings for FGD system components.
1.2.2 It does not cover structural performance of FGD components.
1.2.3 It does not cover use of metallic linings.
1.3 This specification represents the minimum requirements for lining work. In cases where the manufacturer's instructions and recommendations differ from this specification, these differences must be resolved before fabrication is started.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
