Application of OM-4 chimney lining surface treatment agent

After switching to wet flue gas desulfurization technology for electricity, the temperature of chimney exhaust gas significantly decreased, but the humidity increased significantly, the condensation phenomenon became severe, the upward pulling force of flue gas decreased, and the positive pressure zone increased. For ordinary reinforced concrete chimneys that have been built, due to the change in technology, the ability of chimney lining to prevent flue gas infiltration and corrosion has also significantly decreased beyond the original design conditions. Some newly built power plants are like this, with chimneys built but not yet put into use. According to environmental requirements, wet flue gas desulfurization devices need to be added to meet the environmental standards for flue gas emissions; Some power plants have been in operation for many years and need to install wet flue gas desulfurization devices due to environmental requirements.
