Abstract
A method and apparatus for the lining of rounded arcuate chamber areas is disclosed. One edge of a flexible, rectangular sheet of lining material is attached to the substrate wall of the chamber by welding. The opposite end from the now attached side is compressed laterally to bow the sheet into contact with the wall. Keeper welds or attachments are made, trapping the compressive force. The installers are now free to complete the seam welds around the periphery of the sheet. In the preferred embodiment, the sheet is made of a high nickel alloy (HNA) and the arcuate chamber is a desulfurization duct or absorber tower. Successive sheets are overlapped approximately one inch on the sides and top/bottom.
