The corrosion of the induced draft fans in petrochemical plant heaters needs to be addressed urgently
Thread Content
We know that in the exhaust fans of heating furnaces in petrochemical plants, the low-temperature, humid flue gases resulting from the combustion of fuel in the heating furnaces can cause \"flue gas dew point corrosion\" on metals, leading to corrosion of the fan surfaces. A 10-mm-thick carbon steel plate developed local perforations after more than 1 year, and the exhaust fan failed and had to be discarded after more than 2 years. Therefore, equipment used under such operating conditions urgently requires anti-corrosion measures. It is recommended that using a polymer material coating can effectively solve this issue.
Applying a coating made of high-temperature and corrosion-resistant polymer materials to the induced draft fan is an effective solution for corrosion protection. This coating can protect the metal surface and extend the service life of the exhaust fan. .
Made of 304 material; it has a low cost and can be used for a long time
