Anti-corrosion protection for decommissioned boiler in petrochemical enterprise power plants
Thread Content
May I ask the experts if there are any proven protection and anti-corrosion solutions? The current anti-corrosion measures for this boiler are as follows: On the inner side of the furnace tubes – drying for anti-corrosion during the freezing period, and acetaldoxime for anti-corrosion outside that period； — Outer wall of furnace tube: natural ventilation. During operation, this boiler uses fuel oil and fuel gas as fuel, and corrosive substances resulting from the combustion of fuel oil are present on the outside of the boiler’s furnace tubes. How to protect it? Are there any good approaches? Thank you
We used to keep a lot of quicklime here, replacing it regularly!
The principle of water absorption: CaO + H2O → CaCO3
The principle of water absorption: CaO + H2O → CaCO3; reducing moisture also has a certain effect. Thank you
