LINING OF LIGHT POLYMERLIMECONCRETE FOR CHIMNEYS Russian patent published in 2003 - IPC

FIELD: protection of internal surface of brick and reinforced concrete chimneys against corrosive attack of effluent gases when they condense. SUBSTANCE: lining of light polymerlimeconcrete comes in the form of internal laying from clay and acid-proof full bricks installed with clearance relative to wall of chimney shaft filled with light polymerlimeconcrete as soon as laying grows which is linked with fittings to polymerlimeconcrete in every 8-10 rows. Compensator with collapsible vertical faces that does not protrude beyond limits of clearance between laying and shaft is installed in middle of barrel, within the confines of one thickness of walls of chimney shaft. EFFECT: simplified process of lining laying, increased height of barrel, reduced total cost of lining laying. 1 dwg
