Abstract

PURPOSE: To protect the flue and chimney of a heavy oil combustion furnace of boiler or an incinerator for combustion refuse or the like against corrosion, by spraying aqueous alkaline solution of an anticorrosive agent into the flue.
CONSTITUTION: In order to neutralize or increase the pH of condensate of acidic gas such as SO3 and HCl contained in low-temperature exhaust gas passed through an apparatus for preventing environmental pollution, aqueous alkaline solution of an anticorrosive agent is sprayed into the flue or chimney. By the above method, it is enabled to prevent neutralization of concrete and corrosion of steel members. By further supplying an anticorrosive agent, protection of the steel members against corrosion can be rendered complete.
