ABSTRACT:
A chimney lining system is disclosed, in which a membrane, typically 60 mils thick, of corrosion-resistant alloy material is suspended within an external skeletal frame-work of less-expensive carbon steel. Hangers provide for radial expansion of the liner. However, inward movement of the hangers is restrained. Axially spaced circumferential corrugations located midway axially between where two membrane sections are stiffened, joined and connected to the framework, provide for axial expansion. The external framework is disposed within a tubular concrete chimney column. At several levels, grillages support the external framework from the wall of the chimney column. The structural grillages may bear upon load cells equipped to signal the build-up of sludge on the interior of the liner.
