3、 imposed 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 plastics
4、(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 larger d
5、iameters(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)Flue-gas characteri
6、stics such as chemical composition,water and acid dew points,operating and 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,fabrication,and erection pro
7、cess to ensure the integrity of the corrosion barrier andthe 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 inner liners,breeching ductwork,and
8、 miscellaneous platforms,elevators,ladders,and miscellaneous components.The shell provides structural integrity to environmental forces such as wind,earthquake,ambient temperatures,and supports the liner or liners.The liner or liners inside the shell protects the shell from thethermal,chemical,and a
9、brasive environment of the hot boiler gases(generally 120560F(49293C).These liners have beenmade of FRP,acid-resistant brick,carbon steel,stainless steel,high-alloy steel,shotcrete-coated steel,and shotcrete-coated shells.The selection of the material type depends on the chemical composition and tem
10、perature of the flue gas,liner height,diameter,andseismic zone.Also,variations in flue-gas characteristics and durations of transient temperatures affect material selection anddesign.For FRP liners,the flue gas maximum operating temperature is generally limited to 200F(90C)for 2 hours and formaximum
11、 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,confirmatorytesting,quality control and assurance.1.2 These minimum guidelines
