Anticorrosion optimization of reinforced concrete single tube chimney in wet desulfurization condition

Abstract

Abstract:

Since the coalfired power plant adopts wet desulphurization, reinforced concrete single tube chimney has to be used in new projects. To keep this simple and economic chimney available in electric industry, some anticorrosion optimizing measures for chimney structure are proposed after numerous researches were taken on domestic coalfired power plant in current condition and chemical analysis of the flue gas condensation acid was made: using the impermeable concrete cylinder body, sticking two layers of cloth and five glue painting in the lining tube body as seepage prevention and anticorrosion insulation, lining with belt tongueandgroove hydrophobic acidproof brick, closing to the building form of isolation layer. The 210m chimney of Shanxi Guojin Coal Power Company Limited took this measure which is acid resistant and corrosion resistant, and economically applicable. There is no seepage after 3years operation.
