1、Designation: D5364 14 An American National StandardStandard Guide forDesign, Fabrication, and Erection of Fiberglass Reinforced(FRP) Plastic Chimney Liners with Coal-Fired Units1This standard is issued under the fixed designation D5364; the number immediately following the designation indicates the
2、year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONFederal and state environmental regulations have imp
3、osed strict requirements to clean the gasesleaving a chimney. These regulations have resulted in taller chimneys (6001000 ft (183305 m) andlower gas temperatures (120200F (4993C) due to the use of Air Quality Compliance Systems(ACQS). These regulations led to the development of fiber reinforced plas
4、tics (FRP) chimney linersin the 1970s.Fiberglass-reinforced plastic liners have proven their capability to resist corrosion and carry loadsover long periods of time. Successful service has been demonstrated in the utility and general-processindustries for over 40 years. The taller FRPstructures and
5、larger diameters (1030 ft (39 m) imposednew design, fabrication, and erection challenges.The design, fabrication, and erection of FRP liners involves disciplines which must address thespecific characteristics of the material. Areas that have been shown to be of importance include thefollowing:(1) Fl
6、ue-gas characteristics such as chemical composition, water and acid dew points, operatingand excursion temperature, velocity, etc.(2) Plant operation as it relates to variations in the flue-gas characteristics.(3) Material selection and laminate design.(4) Quality control throughout the design, fabr
7、ication, and erection process to ensure the integrityof the corrosion barrier and the structural laminate.(5) Secondary bonding of attachments, appurtenances, and joints.(6) Installation and handling.(7) Inspections and Confirmation Testing.Chimney components include an outer shell, one or more inne
8、r liners, breeching ductwork, andmiscellaneous platforms, elevators, ladders, and miscellaneous components. The shell providesstructural integrity to environmental forces such as wind, earthquake, ambient temperatures, andsupports the liner or liners. The liner or liners inside the shell protects th
9、e shell from the thermal,chemical, and abrasive environment of the hot boiler gases (generally 120560F (49293C). Theseliners have been made of FRP, acid-resistant brick, carbon steel, stainless steel, high-alloy steel,shotcrete-coated steel, and shotcrete-coated shells. The selection of the material
10、 type depends on thechemical composition and temperature of the flue gas, liner height, diameter, and seismic zone. Also,variations in flue-gas characteristics and durations of transient temperatures affect material selectionand design. For FRP liners, the flue gas maximum operating temperature is g
11、enerally limited to 200F(90C) for 2 hours and for maximum transient temperatures to 400F (204C) for 30 minutes.1. Scope1.1 This guide offers direction and guidance to the userconcerning available techniques and methods for design, ma-terial selection, fabrication, erection, inspection, confirmatoryt

Dueto the variability in liner height, diameter, and the environment,each liner must be designed and detailed individually.1.4 Selection of the ne
14、cessary resins and reinforcements,composition of the laminate, and proper testing methods areoffered.1.5 Once the material is selected and the liner designed,procedures for proper fabrication of the liner are developed.1.6 Field erection, sequence of construction, proper field-joint preparation, and
15、 alignment are reviewed.1.7 Quality control and assurance procedures are developedfor the design, fabrication, and erection phases. The quality-assurance program defines the proper authority andresponsibility, control of design, material, fabrication anderection, inspection procedures, tolerances, a

The quality-control procedures provide the stepsrequired to implement the quality-assurance program.1.8 Appendix X1 includes research and development sub-jects to further support recommendations of this guide.1.9 DisclaimerThe reader is cautioned that independentprofession
